Chapter 1: The Legal Environment of Business

Legal disputes are costly, time-consuming, and damaging to business relationships and reputations. The primary goal of business law education for future managers and financial professionals is not to produce lawyers but to cultivate legal risk awareness: the ability to recognize legally significant situations early, understand the range of possible outcomes, and make decisions that minimize legal exposure.

Legal risk management is an ongoing process, not a one-time exercise. It requires integrating legal thinking into business decisions from the earliest planning stages — in contract negotiations, in the choice of business structure, in hiring practices, and in dealings with property. For accounting and finance students, the stakes are especially high: CPA professional standards require practitioners to understand the legal implications of financial reporting, audit engagements, tax advice, and corporate governance.

Why accountants and financial professionals face heightened legal exposure: Accountants prepare and attest to financial statements relied upon by investors, creditors, and regulators. Auditors issue opinions on which third parties depend. Errors, omissions, and misrepresentations in this context can result in civil liability in negligence or contract, regulatory sanctions by the CPA profession, and, in the most serious cases, criminal prosecution under the Criminal Code or securities legislation. Understanding business law is therefore part of professional competence, not merely a theoretical exercise.

1.2 Sources of Law in Canada

Canadian law draws from multiple sources organized in a constitutional hierarchy:

  1. The Constitution Act, 1982 (including the Canadian Charter of Rights and Freedoms): The supreme law of Canada. Any statute or government action inconsistent with the Constitution is invalid to the extent of the inconsistency (s. 52). The Charter protects fundamental freedoms, equality rights, and legal rights, and applies to government action — not private parties. However, governments legislating in commercial areas (employment, securities, competition) must do so consistently with Charter values.

  2. Statute law: Legislation enacted by Parliament (federal) or provincial legislatures within their respective jurisdictions. The division of legislative powers between federal and provincial governments (ss. 91 and 92 of the Constitution Act, 1867) is fundamental to Canadian law. Federal jurisdiction includes criminal law, banking, bankruptcy, patents, copyrights, trade and commerce, and interprovincial and international trade. Provincial jurisdiction includes property and civil rights, contracts, torts, labour relations, and corporate law (provincially incorporated companies).

  3. Common law (case law / judge-made law): The body of principles derived from judicial decisions over centuries. Judges in common law jurisdictions are bound by the doctrine of stare decisis — the principle that courts must follow binding precedent from higher courts within the same jurisdiction. Lower courts are bound by decisions of courts above them in the same hierarchy. The common law evolves incrementally as judges apply existing principles to new factual situations.

  4. Equity: A supplementary body of law developed by courts of equity (Chancery) in England to remedy the rigidities of early common law. Where the strict common law rule produced injustice, equity intervened with discretionary relief. Equitable doctrines — including promissory estoppel, constructive trust, resulting trust, and fiduciary duty — and equitable remedies (injunctions, specific performance, rescission, account of profits) remain vital in Canadian law.

  5. Civil law (Quebec): Quebec’s private law is based on the Civil Code of Québec (CCQ), derived from the French civil law tradition rather than English common law. Unlike common law, the civil law system is codified: the Code is the primary source of private rights and obligations. Federal law and public law apply uniformly across Canada including Quebec. Lawyers and judges in Quebec reason from the Code’s general principles and underlying philosophy rather than from precedent alone.

Stare decisis: Latin for "to stand by things decided." The principle that courts are bound by their own previous decisions and by the decisions of higher courts in the same judicial hierarchy. A decision of the Supreme Court of Canada is binding on all Canadian courts. A decision of the Ontario Court of Appeal is binding on Ontario courts below it, but only persuasive (not binding) in other provinces. Stare decisis promotes predictability, consistency, and fairness in the law.
Ratio decidendi vs. obiter dicta: The ratio decidendi ("reason for deciding") is the legal principle necessary to the outcome of the case — this is the binding part of a precedent. Obiter dicta ("things said in passing") are observations made by the judge that were not strictly necessary to decide the case; they are persuasive but not binding.

1.3 The Canadian Court System

Canada’s court system has multiple levels. Understanding the hierarchy is essential for knowing which decisions are binding and what routes of appeal exist.

Court LevelJurisdiction / Role
Provincial/Territorial CourtsTrial courts of first instance for most civil (small claims) and criminal matters; Family Court in some provinces
Superior Courts of the ProvincesHighest trial courts; unlimited monetary jurisdiction; can hear judicial review of administrative tribunals
Courts of AppealIntermediate appellate courts; hear appeals from Superior Courts; decisions binding on lower courts in the province
Federal CourtSpecialized jurisdiction: judicial review of federal administrative decisions, intellectual property, immigration, admiralty
Federal Court of AppealAppeals from the Federal Court
Supreme Court of CanadaFinal court of appeal for all of Canada; nine judges (by convention, three from Quebec); leave to appeal required in most cases; decisions binding on all Canadian courts

Civil vs. Criminal Law: Business law is primarily concerned with civil law (private disputes between parties), not criminal law (offences against the state). In a civil case, the plaintiff seeks a remedy (typically damages) from the defendant. The standard of proof in civil cases is the balance of probabilities (more likely than not — i.e., greater than 50%). The criminal standard is “beyond a reasonable doubt,” a significantly higher threshold. This distinction matters in professional liability: an accountant acquitted of fraud under the criminal standard may still be found liable in a civil suit.

Administrative Law and Tribunals: Many business disputes are resolved not by courts but by specialized administrative tribunals — the Ontario Securities Commission, the Canadian Human Rights Commission, the Competition Tribunal, labour boards, and others. These bodies have statutory authority to investigate, adjudicate, and impose remedies. Their decisions are subject to judicial review by the Superior Court on grounds of unreasonableness or breach of procedural fairness.

1.4 Dispute Resolution

Not all legal disputes are resolved through court litigation. Alternative dispute resolution (ADR) mechanisms are often faster, cheaper, and more private:

  • Negotiation: Direct discussion between parties to reach a settlement without third-party involvement. Most civil disputes — including most commercial contract disputes — are settled through negotiation, often well before trial.
  • Mediation: A neutral third party (mediator) facilitates discussion and helps parties identify common ground but has no power to impose a solution; the parties must agree voluntarily. Mediation is mandatory in many Ontario family law and civil proceedings. It is increasingly common in commercial and employment contexts.
  • Arbitration: A neutral arbitrator (or panel) hears evidence and arguments and renders a binding decision. Arbitration clauses are common in commercial contracts, employment agreements, and consumer service agreements. In Canada, the Arbitration Act (provincial) and the Commercial Arbitration Act (federal) govern domestic arbitration; international commercial arbitration is governed by the United Nations Commission on International Trade Law (UNCITRAL) Model Law, adopted federally and by most provinces.
  • Litigation: Court-based adjudication; results in a binding, publicly enforceable judgment. Litigation is public (unless the court orders confidentiality), expensive, slow, and adversarial — features that have driven the growth of ADR in commercial practice.
Example — Arbitration in commercial contracts: A large construction contract between a real estate developer and a general contractor contains an arbitration clause: "Any dispute arising out of this Agreement shall be referred to binding arbitration under the Rules of the ADR Institute of Canada." When a payment dispute arises, neither party can sue in court — they must arbitrate. The arbitration award is enforceable as a court judgment. The parties benefit from a faster resolution, a technically expert arbitrator (often a retired judge or senior construction lawyer), and confidentiality of the proceedings and outcome.

Legal risk management involves three stages:

  1. Risk identification: Recognizing which aspects of a planned activity carry legal exposure. For example, entering a new market involves exposure to local contract law, regulatory requirements, intellectual property issues, and employment law in the new jurisdiction.
  2. Risk assessment: Evaluating the likelihood and potential magnitude of each identified risk. A low-probability but catastrophic risk (e.g., product liability) requires different treatment than a high-probability but low-magnitude risk (e.g., a minor contract dispute).
  3. Risk treatment: Choosing a response — avoid the risk (decline the transaction), mitigate it (e.g., through well-drafted contracts, insurance, corporate structure), transfer it (e.g., through indemnification clauses or liability insurance), or accept it (proceed knowing the exposure).
Example: A small business planning to hire its first employee faces legal risks in: employment standards compliance, human rights obligations, occupational health and safety, payroll tax remittance, and potential wrongful dismissal claims. Identifying these risks before the hire — rather than after a complaint is filed — allows for proper employment contracts, workplace policies, and HR procedures to be put in place at minimal cost.

Chapter 2: Tort Law

2.1 What Is a Tort?

A tort is a civil wrong — an act or omission that causes harm to another person, giving rise to liability in damages. Tort law serves to compensate those who are harmed by the wrongful conduct of others and to deter such conduct. Unlike contract law (which arises from agreement between parties), tort obligations are imposed by law regardless of any agreement between the parties. A person can be liable in tort to a complete stranger.

Tort: A wrongful act or omission, other than a breach of contract, that causes harm to another and gives rise to civil liability for damages. Torts can be intentional (battery, fraud, defamation) or unintentional (negligence). The same act may give rise to both tortious liability and criminal prosecution — for example, an assault is both a tort (the victim can sue for damages) and a crime (the state can prosecute).

The primary categories of tort relevant to business are:

  • Negligence (including negligent misrepresentation)
  • Intentional torts (fraud/deceit, defamation, inducing breach of contract, passing off)
  • Occupiers’ liability
  • Products liability

2.2 Negligence

Negligence is the most commercially significant tort. It arises when a person fails to take reasonable care and that failure causes foreseeable harm to another person who was owed a duty of care.

2.2.1 The Historical Development: Donoghue v. Stevenson

The modern law of negligence was born in the landmark House of Lords decision Donoghue v. Stevenson [1932] AC 562. Mrs. Donoghue consumed a ginger beer manufactured by Stevenson that a friend had purchased on her behalf. The bottle contained a decomposed snail. She became ill. She could not sue in contract (she was not a party to the purchase contract). The House of Lords, by majority, held she could sue in tort.

Lord Atkin formulated the neighbour principle: “You must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour. Who, then, in law is my neighbour? The answer seems to be — persons who are so closely and directly affected by my act that I ought reasonably to have them in contemplation as being so affected when I am directing my mind to the acts or omissions which are called in question.”

Donoghue v. Stevenson established two enduring propositions: (1) manufacturers owe a duty of care to the ultimate consumer of their products, and (2) a duty of care in negligence does not depend on a pre-existing contract.

2.2.2 The Anns/Cooper Test — The Canadian Framework for Duty of Care

The Supreme Court of Canada refined the framework for recognizing new duties of care in Cooper v. Hobart [2001] 3 SCR 537, drawing on the English decision in Anns v. Merton London Borough Council [1978] AC 728. The Anns/Cooper test is a two-stage analysis:

Stage 1 — Prima facie duty of care:

  • (a) Was there a sufficiently close relationship of proximity between the parties such that it was reasonably foreseeable that the defendant’s carelessness could cause harm to the plaintiff?
  • (b) Are there any reasons of policy why this prima facie duty should be negatived or limited?

Stage 2 — Residual policy considerations: Even where proximity is established, are there broader policy reasons to deny liability (e.g., the floodgates concern — unlimited liability to an indeterminate class)?

Established vs. novel duty situations: Where a duty of care has already been recognized in a prior case (e.g., manufacturer to consumer, driver to other road users, employer to employee), courts apply the established category directly without re-running the Anns/Cooper analysis. The two-stage test is reserved for genuinely novel factual situations where no established precedent exists.

2.2.3 The Five Elements of Negligence

  1. Duty of care: Did the defendant owe the plaintiff a legal duty to take care? Established by relationship proximity and reasonable foreseeability as above.

  2. Standard of care: What would a reasonable person (a person of ordinary prudence) have done in the circumstances? The standard is objective — courts do not ask what this particular defendant intended to do, but what a hypothetical reasonable person would have done.

  3. Breach of the standard: Did the defendant fall below the reasonable person standard? Courts consider the probability of harm, the severity of potential harm, the utility or social value of the defendant’s conduct, and the burden of taking precautions.

  4. Causation — factual (“but for” test): Did the defendant’s breach actually cause the plaintiff’s loss? The test is: but for the defendant’s negligence, would the plaintiff have suffered the harm? If the harm would have occurred anyway, the negligence is not a cause in fact.

  5. Remoteness of damage: Was the plaintiff’s loss a foreseeable consequence of the breach? The defendant is not liable for damage that is too remote — harm of a type that could not have been reasonably foreseen. The thin skull (or “eggshell skull”) rule: a defendant must take the plaintiff as they find them — if the plaintiff has a pre-existing vulnerability that causes a foreseeable type of harm to be unusually severe, the defendant is liable for the full extent of the harm.

Example — Factual causation: An auditor negligently fails to detect a fraudulent journal entry that materially overstates revenue. The client's board of directors, relying on the audited financial statements, extends credit to a customer who subsequently defaults. The question is whether the auditor's negligence caused the credit loss: but for the negligent audit, would the board have extended credit? If the board would have extended credit regardless of the financial statement figures, the causal link is broken.

2.2.4 The Reasonable Person Standard

The benchmark for breach is the reasonable person: a person of ordinary prudence, knowledge, and skill, who takes appropriate precautions against foreseeable risks. The standard is context-sensitive:

  • Ordinary persons are held to the standard of a reasonable adult of ordinary competence
  • Professionals (accountants, lawyers, engineers, physicians) are held to a higher standard — the conduct of a reasonably competent member of that profession. This is assessed by reference to professional standards, codes of practice, and expert evidence
  • Learners: A learner driver is held to the standard of a reasonably competent driver, not a novice — which is why learner drivers must be supervised

2.2.5 Contributory Negligence and Apportionment

In most provinces, if the plaintiff was also negligent and contributed to the harm, damages are apportioned between the parties under the principle of contributory negligence (comparative fault). Each province has enacted legislation (e.g., Ontario’s Contributory Negligence Act) providing that the plaintiff’s damages are reduced by the percentage that their own negligence contributed to the total harm.

Contributory negligence: A partial defence in negligence. Where the plaintiff's own failure to take reasonable care contributed to the harm they suffered, their damages are reduced in proportion to their degree of fault. The plaintiff is not barred from recovery entirely (as under the old common law rule) but recovers a reduced amount.

2.3 Professional Negligence and Negligent Misrepresentation

Professional negligence is particularly relevant to accountants, auditors, and financial advisors. A professional who carelessly provides incorrect advice or information may be liable for the financial losses that flow from reliance on that advice.

2.3.1 Hedley Byrne — Liability for Negligent Misrepresentation

The House of Lords in Hedley Byrne & Co. Ltd. v. Heller & Partners Ltd. [1964] AC 465 established that liability in negligence can arise from a carelessly made statement (not just a carelessly performed act) causing pure economic loss. The plaintiffs, an advertising agency, relied on a credit reference negligently provided by the defendant bank about a mutual client. The House of Lords held that, absent a contractual disclaimer (which saved the defendant on the facts), a duty of care could arise where:

  • The defendant voluntarily assumes responsibility for providing information
  • The defendant knows (or ought to know) the information will be relied upon by the plaintiff
  • The plaintiff reasonably relies on the information
  • The reliance causes financial loss

Hedley Byrne is the foundation of the tort of negligent misrepresentation and of liability for pure economic loss — that is, financial loss unaccompanied by physical injury or property damage.

2.3.2 Hercules Management Ltd. v. Ernst & Young — Auditor Liability in Canada

The landmark Supreme Court of Canada decision in Hercules Management Ltd. v. Ernst & Young [1997] 2 SCR 165 defined the scope of auditor liability in Canada. The plaintiffs were shareholders who suffered investment losses after relying on audited financial statements that were negligently prepared. They sued the auditors for negligent misrepresentation.

The SCC applied the Anns/Kamloops test and held:

  • At Stage 1, there was a prima facie duty of care: it was reasonably foreseeable that shareholders would rely on the audited financial statements, and there was proximity between auditors and shareholders as a class.
  • At Stage 2, policy considerations limited the duty: unlimited liability to an indeterminate class of claimants (the floodgates concern) justified restricting the duty. Auditors owe a duty of care to the class of persons for whose benefit the audit was conducted (e.g., the company, and shareholders acting collectively in exercising corporate governance rights), but not to individual shareholders using the statements to make personal investment decisions.
Practical implication of Hercules: Auditors who issue financial statements to a defined, limited group of identifiable recipients — such as under an engagement letter specifying that the report is for the use of a specific lender or investor — may face greater exposure to that known group. The broader the distribution and the more varied the potential uses, the more likely Stage 2 policy considerations will limit liability. Professional accountants should ensure engagement letters clearly specify the purpose and intended users of any report or opinion.

2.3.3 Elements of Negligent Misrepresentation (Summary)

For a claim in negligent misrepresentation to succeed, the plaintiff must establish:

  1. There was a duty of care based on a special relationship (voluntary assumption of responsibility, reliance)
  2. The representation was false (incorrect information or advice)
  3. The defendant was negligent in making the representation (fell below the standard of a reasonable professional)
  4. The plaintiff relied on the representation
  5. The reliance was reasonable in the circumstances
  6. The plaintiff suffered loss as a result

2.4 Vicarious Liability

An employer is vicariously liable for torts committed by an employee in the course of employment, even if the employer was not personally at fault. The rationale is that employers benefit from the work of employees and are better positioned to bear and distribute the loss through insurance and pricing.

Vicarious liability: The liability imposed on one person (the employer or principal) for the tortious acts of another (the employee or agent) committed within the scope of the employment or agency relationship. The employee remains personally liable; vicarious liability is in addition to, not instead of, the employee's own liability.

The scope of vicarious liability has expanded in Canada. The Supreme Court of Canada in Bazley v. Curry [1999] 2 SCR 534 established a two-step approach: (1) Is there a precedent establishing vicarious liability on analogous facts? If so, apply it. (2) If not, should vicarious liability be imposed based on policy? Policy supports vicarious liability where the employment enterprise created or materially enhanced the risk that materialized in the tort.

In professional services firms (accounting firms, law firms), vicarious liability is particularly significant: a partner or senior professional who negligently causes loss to a client creates liability for the entire firm.

2.5 Intentional Torts in Business

Several intentional torts arise in commercial and professional contexts:

2.5.1 Fraud (Deceit)

Fraud (or the tort of deceit) requires: (1) a false representation of fact; (2) made with knowledge of its falsity (or reckless as to whether it was true); (3) with intent that the plaintiff would rely on it; (4) the plaintiff does rely; and (5) suffers damage as a result. Unlike negligent misrepresentation, fraud requires conscious dishonesty. Fraud in a financial reporting context — deliberately falsifying financial statements — can give rise to civil liability in the tort of deceit in addition to criminal prosecution under ss. 380 and 382 of the Criminal Code (fraud and market manipulation).

2.5.2 Defamation

Defamation is the publication of a false statement of fact to at least one person other than the claimant, identifying the claimant, that damages the claimant’s reputation. In business contexts, defamation arises in:

  • Employment references (negative statements about a former employee)
  • Credit reports (false statements about a company’s creditworthiness)
  • Competitive disparagement (false statements about a competitor’s products)

Key defences include:

  • Truth (justification): A true statement cannot be defamatory
  • Qualified privilege: Statements made in good faith in circumstances where there is a duty (social, moral, or legal) to communicate and a corresponding interest in receiving the information are protected, provided there is no malice. Employment references attract qualified privilege.
  • Fair comment: Honest opinion on a matter of public interest

2.5.3 Passing Off

Passing off occurs when a business represents its goods or services as those of another, causing confusion and damage to the latter’s goodwill. The three elements are: (1) the plaintiff has goodwill in a distinctive get-up (name, logo, trade dress); (2) the defendant made a misrepresentation likely to confuse the public; (3) the plaintiff suffered or is likely to suffer damage. Passing off is the common law forerunner of statutory trademark protection.

2.5.4 Inducing Breach of Contract

A defendant who intentionally and without justification induces a third party to breach their contract with the plaintiff is liable for the resulting damage. This tort is relevant in competitive business situations — for example, where a company induces key employees of a competitor to break their employment contracts.

2.6 Occupiers’ Liability

The owner or occupier of land or premises has legal obligations toward those who enter. Canadian provinces have generally enacted Occupiers’ Liability Acts (e.g., Ontario’s Occupiers’ Liability Act, RSO 1990, c. O.2) that replace the old common law categories with a single standard: the occupier must take reasonable care in all the circumstances to make the premises reasonably safe. Retail businesses, offices, and commercial landlords are routinely defendants in slip-and-fall and related claims.


Chapter 3: Contract Law

3.1 What Makes a Contract?

A contract is a legally enforceable agreement. For a contract to be valid and enforceable, all of the following elements must be present:

ElementRequirement
OfferA definite, complete proposal communicated to the offeree with intention to be bound
AcceptanceUnconditional agreement to all terms of the offer (mirror image rule)
ConsiderationValue given by each party in exchange for the other’s promise
Intention to create legal relationsObjective intention that the agreement be legally binding
CapacityBoth parties must have legal capacity to contract
LegalityThe purpose and subject matter must not be illegal or contrary to public policy
Consideration: Something of value given or promised by each party to a contract in exchange for the other's promise. Consideration must be: (1) sufficient — have some legal value (a peppercorn is sufficient); (2) not past — something already done before the promise is not good consideration; (3) not illusory — a promise to do something one is already legally obliged to do is generally not consideration. Consideration need not be adequate (equal in monetary value).
Example — Past consideration: An employee saves her employer from a fire at great personal risk. The next day, the grateful employer promises her a \$10,000 bonus. Later, the employer refuses to pay. The employee cannot enforce the promise because her act of saving the employer happened before the promise — it is past consideration. There was no bargained-for exchange. However, if the employer had promised the bonus before the act (inducing it), there would be consideration and an enforceable contract.

3.2 Formation of a Contract

3.2.1 Offer

An offer is a definite, complete proposal to enter into an agreement on specified terms, communicated to the offeree, with the intention to be legally bound upon acceptance. An offer must be distinguished from:

  • Invitation to treat: A preliminary communication inviting offers, not itself an offer. Examples: advertisements in newspapers, price tags in stores, auction listings, requests for tenders. In Pharmaceutical Society of Great Britain v. Boots Cash Chemists [1953] 1 QB 401, the display of goods on shelves was an invitation to treat; the customer makes the offer at the cash register.
  • Preliminary negotiations: Expressions of interest, letters of intent (unless clearly binding), and negotiations that have not yet crystallized into a definite proposal

An offer may be terminated by:

  • Revocation: Withdrawal by the offeror before acceptance. Must be communicated to the offeree. An option contract (supported by consideration) irrevocably holds the offer open for the option period.
  • Rejection or counter-offer: A counter-offer (conditional or modified acceptance) terminates the original offer and creates a new one (Hyde v. Wrench (1840))
  • Lapse of time: An offer lapses after the stated time, or (if no time stated) after a reasonable time
  • Death or mental incapacity of the offeror (in most cases)

3.2.2 Acceptance

Acceptance must be: (1) unconditional and complete (the mirror image rule — the acceptance must match the offer exactly); (2) communicated to the offeror (generally, acceptance is effective when received by the offeror); (3) made while the offer is still open.

The postal rule (mailbox rule): An exception to the communication requirement. Where it is within the reasonable contemplation of the parties that the post might be used as the means of communicating acceptance, acceptance is complete and binding at the moment the acceptance letter is posted, even before it is received. This rule creates certainty but can produce anomalous results; it has largely been displaced in practice by electronic communication.

Electronic contracts: Provincial Electronic Commerce Acts (e.g., Ontario’s Electronic Commerce Act, 2000) confirm that contracts can be validly formed electronically. An electronic acceptance is effective when it enters the offeror’s information system in a readable form.

The law presumes that:

  • Commercial/business agreements are intended to be legally binding. Businesses deal on the assumption that their agreements will be enforceable.
  • Domestic and social agreements are presumed not to be legally binding (e.g., a promise between spouses, an agreement to meet for lunch). The presumption can be rebutted by evidence of clear intention to create legal relations.

3.2.4 Capacity

  • Minors (persons under the age of majority): The age of majority is 18 in Ontario, Manitoba, Quebec, Prince Edward Island, Saskatchewan, and Alberta; 19 in British Columbia, New Brunswick, Newfoundland and Labrador, Nova Scotia, Nunavut, Northwest Territories, and Yukon. Contracts with minors are generally voidable at the minor’s option. Contracts for necessaries (food, clothing, shelter, education appropriate to the minor’s station in life) are enforceable. A minor who repudiates a contract on reaching the age of majority must act promptly.
  • Mental incapacity: A contract is voidable where a party lacked the mental capacity to understand the nature of the contract, and the other party knew (or ought to have known) of the incapacity. A person under a formal legal guardianship order cannot contract.
  • Corporations: A corporation has contractual capacity for anything within its corporate purposes. Historically, the ultra vires doctrine invalidated contracts beyond the corporation’s objects; modern corporation statutes (CBCA, OBCA) generally eliminate the ultra vires doctrine and provide full contracting capacity.
  • Intoxication: A contract may be voidable if a party was so intoxicated that they could not understand what they were doing, and the other party was aware of this.

3.2.5 Legality

A contract whose purpose or subject matter is illegal is void (has no legal effect). Categories of illegal contracts include:

  • Contracts to commit a crime or a tort
  • Contracts prohibited by statute (e.g., unlicensed activity in a regulated profession)
  • Contracts contrary to public policy — including contracts in restraint of trade that are unreasonably broad

Restraint of trade clauses: Non-competition and non-solicitation agreements in employment or business sale contracts are enforceable only if they are reasonable in scope, geographic area, and duration. Courts will refuse to enforce an unreasonably broad restraint. Ontario’s Working for Workers Act, 2021 and 2022 amendments introduced new restrictions on non-competition agreements in employment.

3.3 Terms of a Contract

3.3.1 Express and Implied Terms

  • Express terms: Terms explicitly agreed to by the parties, either orally or in writing
  • Implied terms: Not stated explicitly but read into the contract by:
    • Fact (the business efficacy test and the officious bystander test): implied where necessary to give the contract its obvious commercial effect
    • Law: terms implied into certain classes of contract by statute — e.g., the Sale of Goods Act implies conditions of merchantable quality and fitness for purpose into sales of goods by a dealer
    • Custom: terms customary in a particular trade or industry may be implied if well-known and invariably acted upon

3.3.2 Conditions vs. Warranties

The classification of a term as a condition or warranty determines the remedy available for breach:

Condition: A fundamental term going to the root of the contract. Breach of a condition entitles the innocent party to treat the contract as discharged (terminated) and to claim damages. The innocent party may also elect to affirm the contract and sue for damages only.
Warranty: A minor or subsidiary term. Breach of a warranty gives the innocent party a right to damages only — the contract continues in force. The innocent party cannot terminate merely because of a warranty breach.

Some terms are innominate (intermediate) terms: the remedy depends on the severity of the consequences of the breach. A serious breach with severe consequences is treated like a breach of condition; a minor breach with trivial consequences is treated like a breach of warranty.

3.3.3 The Parol Evidence Rule and Its Exceptions

Where parties have reduced their agreement to writing, the parol evidence rule holds that extrinsic evidence (oral statements, prior negotiations, collateral agreements) cannot be used to add to, vary, or contradict the written terms. The rule promotes certainty and protects written agreements from being undermined by disputed oral evidence.

Major exceptions:

  • Evidence to prove the contract is voidable (e.g., for misrepresentation or duress)
  • Evidence to interpret an ambiguous term
  • Evidence of a collateral contract (a separate, valid contract made at the same time)
  • Evidence of a condition precedent to the contract coming into effect
  • Evidence of custom or trade usage

3.3.4 Exemption (Exclusion) Clauses

Clauses that exclude or limit liability are frequently encountered in commercial contracts and consumer transactions (e.g., parking lot disclaimers, software licence agreements, shipping terms). Such clauses are enforceable only if:

  1. Incorporated into the contract: The other party must have been aware of the clause before or at the time the contract was formed. A clause introduced after formation does not bind the party (e.g., a disclaimer on a receipt presented after payment).
  2. Clearly worded to cover the breach in question: Exemption clauses are construed contra proferentem — any ambiguity is resolved against the party who drafted and seeks to rely on the clause.
  3. Not voided by statute: Consumer protection legislation (e.g., Ontario’s Consumer Protection Act, 2002) renders void any clause that purports to limit statutory implied conditions of quality in consumer transactions.
Example — Contra proferentem: A storage facility contract states: "The company shall not be liable for loss of or damage to goods." A customer's goods are destroyed due to a fire caused by the storage facility's employee's negligence. The company claims the clause exempts it. A court applying contra proferentem might hold that "damage to goods" does not clearly include damage caused by the company's own negligence — the clause must be construed against the drafter (the storage company), so the exemption does not apply. To be effective, the clause would need to explicitly state "including damage caused by our own negligence or that of our employees."

3.3.5 Standard Form Contracts and Unconscionability

Standard form (boilerplate) contracts — prepared by one party for use in many identical transactions — pervade commerce: employment contracts, insurance policies, software licences, bank loan agreements, franchise agreements, and consumer service terms. They present one-sided drafting and unequal bargaining power: the other party must accept all terms or decline the deal entirely (“take it or leave it”).

Courts have developed doctrines to police unfair standard form contracts:

  • Unconscionability: Where there is an inequality of bargaining power and the resulting contract is improvident (unreasonably advantageous to the stronger party), courts may refuse enforcement or may sever the offending term
  • Reasonable expectations: In insurance contracts, courts may hold that policy terms that defeat the insured’s reasonable expectations of coverage are unenforceable
  • Statutory control: The Consumer Protection Act and Insurance Act impose mandatory terms and prohibit unfair practices in consumer and insurance contracts

3.4 Representations vs. Terms

A representation is a statement of fact made before or during negotiations that induces the other party to enter the contract but does not become a term of the contract. A term is a promise that forms part of the contract and creates contractual obligations. The distinction matters for remedies:

  • Breach of a term → remedies in contract (damages, possibly termination)
  • A false representation → remedies in tort (rescission of the contract, damages for misrepresentation)

Factors for determining whether a statement is a term or representation:

  • Importance attached to the statement by the parties
  • Whether the party making the statement had special knowledge or skill
  • Whether there was an interval of time between the statement and the formation of the contract
  • Whether the statement was reduced to writing

3.5 Vitiating Factors — Setting Aside the Contract

3.5.1 Misrepresentation

A misrepresentation is a false statement of existing fact (not opinion, not law, not prediction) made by one party to the other that induces the other to enter the contract. A misrepresentation makes the contract voidable at the innocent party’s option.

Type of MisrepresentationDefinitionRemedies
FraudulentMade knowingly, or without belief in its truth, or recklesslyRescission + damages in tort (deceit)
NegligentMade carelessly by a person in a special relationshipRescission + damages in tort (negligent misrepresentation)
InnocentMade without fault, in reasonable belief of truthRescission (damages at court’s discretion under some statutes)

The remedy of rescission is the setting aside of the contract and the restoration of each party to their pre-contract position. Rescission may be barred if the innocent party has affirmed the contract, if third party rights have intervened, or if restitution in integrum is impossible.

3.5.2 Mistake

Common mistake: Both parties share the same fundamental mistaken belief at the time of contracting. If the mistake goes to the root of the contract (e.g., the subject matter does not exist, Couturier v. Hastie (1856)), the contract is void at common law or may be rescinded in equity.

Mutual mistake: The parties are at cross-purposes, each intending something different. If the parties’ intentions are so divergent that no agreement was ever reached, the contract is void.

Unilateral mistake: Only one party is mistaken, and the other knows it. The contract is generally not void, but equity may grant rescission in very limited circumstances (e.g., where the other party deliberately created or took advantage of the mistake).

Non est factum (“it is not my deed”): A special plea where a party signed a document fundamentally different in character from what they believed they were signing, without negligence. If established, the contract is void even against a third party — making it relevant in secured lending and real property transactions.

3.5.3 Undue Influence

Undue influence arises where one party dominates the other’s will, taking unfair advantage of a position of trust or influence. Actual undue influence must be proven on the facts. Presumed undue influence arises automatically from certain recognized relationships (solicitor-client, trustee-beneficiary, parent-child, doctor-patient, religious adviser-disciple). Where the presumption applies, the dominant party must rebut it by showing independent advice and free exercise of will.

In commercial lending, undue influence is most frequently raised where a spouse guarantees a business partner’s (often their spouse’s) loan to a bank. Courts have developed specific guidance on when banks are put on inquiry regarding potential undue influence (Royal Bank of Scotland v. Etridge (No.2) [2001] UKHL 44 — the English decision is persuasive in Canada).

3.5.4 Duress

Physical duress (threats of physical harm) has long made a contract voidable. Modern courts also recognize economic duress: illegitimate commercial pressure that leaves the victim with no practical alternative but to capitulate. Economic duress typically requires (1) illegitimate pressure (e.g., a threat to breach a contract unless more money is paid), (2) the pressure was a significant cause of the party’s assent, and (3) the party had no reasonable alternative.

3.5.5 Unconscionability

The doctrine of unconscionability allows courts to refuse enforcement of — or to modify — contracts that are grossly unfair and formed in circumstances of inequality. The two requirements are: (1) inequality of bargaining power (including poverty, ignorance, need, or emotional vulnerability); and (2) a substantively improvident bargain. Where established, the court may void the contract or sever the unconscionable term.

3.6 Discharge of a Contract

A contract is discharged when the parties’ obligations under it are ended.

3.6.1 Discharge by Performance

The most common mode: both parties fully and precisely perform all their contractual obligations. Substantial performance may discharge obligations while the partially performing party may have to compensate for any shortfall.

3.6.2 Discharge by Agreement

Parties may agree to end their contract (rescission by mutual consent), to vary its terms (variation), or to substitute a new contract in its place (novation).

3.6.3 Discharge by Frustration

A contract is frustrated when, after formation, an unforeseen event occurs that makes performance impossible, illegal, or radically different from what the parties contemplated. The doctrine discharges both parties from further performance.

Frustration: The doctrine that discharges a contract when a supervening event, not caused by either party and not contemplated by the contract, makes performance impossible or radically different. Classic examples: destruction of the specific subject matter (*Taylor v. Caldwell* (1863) — a music hall burned down); supervening illegality; death or incapacity of the required performer; cancellation of the event for which the contract was made (coronation cases).

COVID-19 and frustration: The pandemic raised numerous frustration arguments in Canada. Courts examined whether commercial lease obligations, event venue contracts, and supply contracts were frustrated when government orders prohibited the relevant activities. Many courts found the doctrine difficult to apply where the contract merely became less profitable rather than impossible to perform.

Provincial legislation (e.g., Ontario’s Frustrated Contracts Act) governs the restitutionary consequences — restoring benefits conferred before the frustrating event and apportioning losses equitably.

3.6.4 Discharge by Breach

A party who commits a sufficiently serious breach (breach of a condition, or a repudiatory breach going to the root of the contract) gives the innocent party the right to elect:

  • Accept the repudiation: Treat the contract as discharged, claim damages, and be free from further performance obligations
  • Affirm the contract: Continue to demand performance, hold the contract alive, and sue for damages when they fall due

3.7 Remedies for Breach of Contract

3.7.1 Damages

Damages are the primary remedy for breach of contract. The expectation interest (putting the plaintiff in the position they would have been in had the contract been performed) is the primary measure.

Heads of damages:

  • Expectation (loss of bargain): The value of what the plaintiff was promised minus what they actually received
  • Reliance loss: Expenditures incurred in reliance on the contract that have been wasted by the breach
  • Consequential (special) losses: Additional losses flowing from the breach, beyond the direct loss

The rule in Hadley v. Baxendale (1854) 9 Exch 341 limits recoverable damages to losses that:

  1. Arise naturally from the breach in the ordinary course of things (general/direct damages); or
  2. Were within the reasonable contemplation of both parties at the time of contracting as a probable consequence of breach (special/consequential damages, recoverable only if the defendant had actual knowledge of the special circumstances)
Mitigation: The innocent party has a duty to take reasonable steps to minimize their loss following a breach. Damages will not be awarded for losses that the plaintiff could have avoided through reasonable effort. For example, a wrongfully dismissed employee must take reasonable steps to find comparable employment; damages are reduced by what they did (or reasonably should have) earn in new employment.

Liquidated damages vs. penalty clauses: Parties may pre-agree the damages payable on breach (liquidated damages). A liquidated damages clause is enforceable if it is a genuine pre-estimate of loss at the time of contracting. A penalty clause — one that imposes a sum grossly disproportionate to any conceivable loss and is designed to deter breach rather than compensate — is unenforceable at common law.

3.7.2 Specific Performance

An equitable remedy ordering the breaching party to actually perform their contractual obligations. Courts award specific performance only when damages are an inadequate remedy:

  • Contracts for unique property (land, rare chattels, unique goods)
  • Where the subject matter is so distinctive that no substitute can be obtained

Specific performance is discretionary: courts may refuse it where the contract involved personal services (courts will not compel personal service — it would amount to forced labour), where hardship would result, or where the plaintiff has acted inequitably.

3.7.3 Injunction

An equitable remedy prohibiting a party from doing something. In contract law, injunctions are used to enforce negative contractual obligations — e.g., a non-competition or non-solicitation clause after employment ends. An injunction will not compel a former employee to work for an employer, but it can restrain them from working for a competitor in breach of a valid non-competition agreement.

Interlocutory (interim) injunctions are granted pending trial where: (1) there is a serious question to be tried; (2) the balance of convenience favours granting the injunction; and (3) damages would not be an adequate remedy (American Cyanamid v. Ethicon [1975] AC 396, adopted in Canada).

3.7.4 Rescission

Rescission is the setting aside of a contract for a vitiating factor (misrepresentation, mistake, duress, undue influence). It restores both parties to their pre-contract positions. Rescission is lost if the innocent party affirms the contract after discovering the vitiating factor.


Chapter 4: Business Organizations

4.1 Choice of Business Form

The legal structure chosen for a business has profound consequences for liability, taxation, management flexibility, and financing. The main options in Canada are: sole proprietorship, general partnership, limited partnership, limited liability partnership, corporation, and (in Quebec) the general partnership with legal personality.

4.2 Sole Proprietorship

The simplest form — one owner who operates the business personally. Key characteristics:

  • The proprietor has unlimited personal liability for all debts and obligations of the business
  • There is no legal distinction between the business and the individual — they are the same legal person
  • Income is taxed at the individual’s marginal tax rate (no separate corporate tax filing)
  • Easy and cheap to establish; terminates on the death of the proprietor
  • Common for small tradespeople, consultants, and professionals in the early stages of practice

4.3 General Partnership

Two or more persons carrying on business in common with a view to profit. By default, governed by provincial Partnership Acts (e.g., Partnerships Act, RSO 1990, c. P.5, based on the English Partnership Act, 1890).

Key features:

Mutual agency: Each partner is an agent of the firm and of every other partner for the purposes of the firm's business. An act of a partner carried out in the ordinary course of the firm's business binds all partners, even if the other partners did not consent and even if the act was beyond that partner's internal authority — provided the third party was not aware of the limitation.
Joint and several liability: Each partner is personally liable for all debts and obligations of the partnership — not just their proportionate share, and not just debts incurred by themselves. A creditor can sue any one partner (or all of them) for the full amount of any partnership debt. This is perhaps the most significant risk of the general partnership form.
  • No separate legal personality in most common law provinces (unlike a corporation): the partnership is not a separate legal person apart from its partners. (This differs from civil law — in Quebec, a general partnership (société en nom collectif) is a legal person.)
  • Division of profits and management: Partners share profits and management equally unless the partnership agreement provides otherwise
  • Good faith and fiduciary duties: Partners owe each other duties of good faith, loyalty, and account for secret profits
Example — Joint and several liability: A three-partner accounting firm's junior partner, while engaged in firm business, negligently advises a client, causing a \$900,000 loss. The client sues. All three partners are jointly and severally liable for the full \$900,000 — the client can recover the entire amount from any one of them, regardless of their internal profit-sharing arrangement. The partner who pays can seek contribution from the others under the partnership agreement, but that is an internal matter.

4.4 Limited Partnership

A hybrid form established by provincial Limited Partnerships Acts. It requires:

  • At least one general partner: has unlimited liability and management authority; runs the business
  • At least one limited partner: liability is limited to their capital contribution; no management participation

The critical rule: if a limited partner takes part in control of the business, they may lose limited liability and be treated as a general partner. Limited partnerships are commonly used for investment funds, real estate ventures, and tax shelter structures, where investors (limited partners) seek limited liability and pass-through tax treatment without management responsibility.

4.5 Limited Liability Partnership (LLP)

The LLP form is used by professional firms (lawyers, accountants) that cannot incorporate but want to protect innocent partners from liability for colleagues’ professional negligence. In an LLP:

  • Each partner’s personal assets are shielded from the negligent acts of other partners (in which they had no involvement)
  • Partners remain personally liable for their own negligence and for firm debts generally
  • LLPs must be registered and are available only in certain provinces for designated professions

4.6 The Corporation

The corporation is the dominant vehicle for larger businesses and many small ones. It is created by filing articles of incorporation under either federal (Canada Business Corporations Act, CBCA) or provincial legislation (Business Corporations Act, OBCA in Ontario; Business Corporations Act, BCBCA in British Columbia; similar legislation in each province).

The foundational principle of corporate law is separate legal personality: a corporation is a legal person distinct from its shareholders, directors, and officers.

The House of Lords established this definitively in Salomon v. A. Salomon & Co. Ltd. [1897] AC 22. Mr. Salomon incorporated his boot-making business and sold it to the corporation for shares and secured debentures. When the company became insolvent, unsecured creditors argued that the company and Mr. Salomon were one and the same, so he should be personally liable. The House of Lords unanimously rejected this argument: the corporation was validly incorporated and was a legal person entirely separate from Mr. Salomon. As a secured creditor, Salomon ranked ahead of unsecured creditors. Separate personality is not a sham merely because one person controls the company.

Consequences of separate legal personality:

  • The corporation can own property in its own name
  • The corporation can sue and be sued in its own name
  • The corporation can enter contracts in its own name
  • Shareholders are generally not liable for the debts and obligations of the corporation
  • The corporation continues to exist regardless of changes in ownership or the death of shareholders
  • The corporation can continue indefinitely (perpetual succession)

4.6.2 Limited Liability of Shareholders

Shareholders’ liability is limited to the amount they agreed to pay for their shares. Once shares are fully paid, the shareholder has no further obligation. This feature facilitates investment by separating the risk of ownership from unlimited personal exposure. Small business owners often give up this protection by personally guaranteeing corporate loans — banks routinely require personal guarantees from shareholders of closely held corporations.

4.6.3 Lifting the Corporate Veil

Courts will disregard the separate corporate personality — “lift” or “pierce the corporate veil” — in limited circumstances:

  • Statutory piercing: Some statutes impose personal liability on directors or officers (e.g., for unremitted source deductions, unpaid wages, environmental liability under certain statutes)
  • Fraud or sham: Where the corporate form is used as a tool to perpetrate fraud, or where the corporation is a mere sham with no independent existence — the court will look through it
  • Agency: Where the corporation acts as agent for the shareholder (rarely found; courts scrutinize such arrangements carefully)
  • Single economic enterprise: Canadian courts have generally been reluctant to pierce the veil merely because of related-party transactions or common control among a corporate group (Clarkson Co. v. Zhelka (1967) 64 DLR (2d) 457)
For accounting students: The limited liability of corporations and the circumstances in which it may be lost (personal guarantees, director liability for taxes, piercing the veil in regulated contexts) are directly relevant to financial planning, corporate restructuring, and advice on business structures.

4.6.4 Corporate Governance — Directors and Officers

Board of Directors: The corporation is managed by or under the direction of a board of directors (s. 102 CBCA). Directors are elected by shareholders and are responsible for overseeing management, approving major decisions (mergers, significant contracts, financial statements), and ensuring the corporation acts within its legal obligations.

Officers: Appointed by the board; responsible for day-to-day management. Typical officers: CEO (Chief Executive Officer), CFO (Chief Financial Officer), Secretary, and others.

Duties of Directors and Officers — under the CBCA (s. 122) and equivalent provincial statutes, directors and officers owe two fundamental duties to the corporation:

Duty of care (s. 122(1)(b) CBCA): Every director and officer of a corporation in exercising their powers and discharging their duties shall act with the care, diligence, and skill that a reasonably prudent person would exercise in comparable circumstances. This is an objective standard.
Fiduciary duty / duty of loyalty (s. 122(1)(a) CBCA): Every director and officer shall act honestly and in good faith with a view to the best interests of the corporation. This duty requires directors to: avoid conflicts of interest, disclose conflicts if they arise, not appropriate corporate opportunities for personal benefit, and not make secret profits.

The Business Judgment Rule: Courts defer to the business decisions of directors made in good faith, after reasonable inquiry, and within the range of reasonable alternatives — even if the decision later proves wrong. Courts recognize they should not second-guess commercial judgments made at the time with the information available. To benefit from the rule, directors must be informed (they must make reasonable inquiry) and must act in the corporation’s interests without conflict.

Conflicts of interest: A director who has a material interest in a contract or transaction with the corporation must disclose the conflict (s. 120 CBCA) and, in most cases, abstain from voting. Failure to disclose creates liability to account for profits and may result in the transaction being voided.

Personal liability of directors — beyond the fiduciary and duty of care claims:

  • Wages: Directors are jointly and severally liable for up to 6 months of wages unpaid by the corporation if the corporation becomes insolvent and wage claims are not satisfied (s. 119 CBCA)
  • Source deductions: Under the Income Tax Act, directors may be personally liable for a corporation’s failure to remit employee source deductions (CPP, EI, income tax) — subject to a due diligence defence
  • Environmental: In some contexts, directors may face personal liability under environmental statutes if they fail to prevent contraventions

4.6.5 Shareholders’ Rights

Under the CBCA and equivalent legislation, shareholders have:

  • The right to elect (and remove) directors
  • The right to vote on fundamental changes (amalgamation, continuance, sale of substantially all assets, dissolution)
  • The right to receive financial statements and attend annual meetings
  • Dissent and appraisal rights (s. 190 CBCA): Shareholders who object to certain fundamental changes may dissent and demand fair value for their shares
  • Oppression remedy (s. 241 CBCA): A shareholder (or other stakeholder) who is being treated in a way that is oppressive, unfairly prejudicial, or that unfairly disregards their interests may apply to court for a broad range of remedies — the most powerful and widely used shareholder remedy in Canada
Example — Oppression remedy: Two equal shareholders in a private corporation have a falling-out. The majority shareholder, who is also the sole director, stops paying dividends, increases her own salary to excessive levels, and excludes the minority from management. The minority shareholder applies to the court under s. 241 CBCA. The court may order: payment of dividends, reduction of salary, appointment of an independent director, or (in an extreme case) the buyout of the minority's shares at fair value.

Chapter 5: Property Law

5.1 Real Property

Real property (real estate) includes land and anything permanently attached to it (buildings, fixtures). The law governing real property in common law provinces descends from the English feudal tenure system. Key concepts:

  • Fee simple: The largest ownership interest in land — the right to use, sell, mortgage, lease, or bequeath the property. Effectively full ownership.
  • Leasehold: A time-limited right to occupy property under a lease agreement, governed by both contract law (the lease) and provincial landlord-tenant legislation (Commercial Tenancies Act, Residential Tenancies Act)
  • Easements: Rights to use another’s land for a specific purpose (e.g., right of way, utilities)
  • Restrictive covenants: Promises that burden land (e.g., prohibiting commercial use of residential property); can “run with the land” and bind successors in title
  • Mortgages: A security interest in land granted by the borrower (mortgagor) to the lender (mortgagee) to secure a loan. On default, the mortgagee may exercise power of sale (sell the property without court order, in most provinces) or seek foreclosure (transfer title to the lender)

Land title registration: Most Canadian provinces use Torrens title systems (Land Titles Acts) that guarantee the accuracy of the registered title. Registration gives notice to the world; an unregistered interest may be defeated by a subsequent purchaser who registers first without notice of the prior interest. Ontario’s land registration system operates electronically through Teraview.

5.2 Personal Property

Personal property includes all property other than real estate:

  • Tangible property (chattels): Physical, movable objects — inventory, equipment, vehicles, goods
  • Intangible property (choses in action): Rights enforceable by legal action — accounts receivable, intellectual property rights, contractual rights, shares

5.2.1 Personal Property Security — the PPSA

When a lender takes security over personal property (e.g., a bank financing a business’s inventory, a car dealer’s floorplan financing), the security interest must be perfected to be effective against third parties. Each common law province has enacted a Personal Property Security Act (PPSA) governing security interests in personal property.

Key PPSA concepts:

Attachment: The security interest is created and binding between the parties when: (1) value has been given; (2) the debtor has rights in the collateral; and (3) the parties have a security agreement (in writing or evidenced in writing, signed by the debtor, describing the collateral).
Perfection: The process by which the secured party establishes priority over third parties (other creditors, the trustee in bankruptcy, buyers). Perfection is typically achieved by registration in the PPSA registry (filing a financing statement) or by possession of the collateral. An unperfected security interest is effective between the debtor and secured party but loses priority to a perfected security interest, a subsequent lien holder, and the trustee in bankruptcy.

Priority among competing secured creditors is generally determined by first to file or first to perfect (the rule varies slightly by type of collateral). A purchase money security interest (PMSI) — a security interest that enables the debtor to acquire the specific collateral (e.g., a vendor who sells goods on secured credit) — has “super-priority” over prior perfected security interests, provided it is registered within specific time periods.

5.3 Intellectual Property

Intellectual property (IP) protects creations of the mind. IP rights are territorial (must be obtained in each country where protection is sought) and time-limited. The main forms in Canada:

TypeGoverning StatuteDurationSubject Matter
PatentPatent Act, RSC 1985, c. P-420 years from filing dateNovel, useful, non-obvious inventions (products, processes, machines, compositions of matter)
CopyrightCopyright Act, RSC 1985, c. C-42Life of author + 70 years (general rule)Original literary, dramatic, musical, and artistic works; software; compilations
TrademarkTrademarks Act, RSC 1985, c. T-13Renewable 10-year terms (indefinitely)Distinctive marks, logos, trade dress, certification marks, distinguishing guises
Industrial DesignIndustrial Design Act, RSC 1985, c. I-910 yearsVisual features (shape, pattern, ornamentation) of mass-produced articles
Trade SecretCommon law (confidentiality)Indefinite (while secret maintained)Confidential business information, formulae, processes, customer lists

5.3.1 Patents

A patent grants the inventor the exclusive right to make, use, and sell an invention for 20 years from the filing date, in exchange for disclosure. Requirements:

  • Novelty: The invention must not have been publicly disclosed before the filing date (subject to limited grace periods in Canada)
  • Utility: The invention must be useful — it must achieve its claimed purpose
  • Non-obviousness (inventive step): The invention must not be obvious to a person skilled in the relevant field

Patent protection is critical in the pharmaceutical, technology, and manufacturing industries. The race to file is important: Canada’s patent system requires the first to file (not the first to invent).

Copyright arises automatically upon creation of an original work — no registration is required in Canada (though registration is available and creates a presumption of ownership and subsistence). Copyright protects the expression of an idea, not the idea itself. The owner has the exclusive right to reproduce, perform, publish, communicate, and adapt the work.

Software: Computer programs are protected as literary works under the Copyright Act. Copyright in software does not protect the underlying ideas, algorithms, or functionality — only the specific code.

Fair dealing: Users have the right to make fair use of copyrighted works for research, private study, education, parody, criticism, review, and news reporting. The Copyright Act (s. 29) and the Supreme Court of Canada in CCH Canadian Ltd. v. Law Society of Upper Canada [2004] 1 SCR 339 established that fair dealing is a user’s right, to be interpreted broadly and in a user-friendly manner.

Moral rights: Independent of economic rights, the author of a copyrighted work has moral rights — the right to the integrity of the work (not to have it distorted or modified in a way prejudicial to honour or reputation) and the right of attribution (to be associated with the work). Moral rights cannot be assigned but can be waived.

5.3.3 Trademarks

A trademark is a sign used to distinguish the goods or services of one business from those of another. It may consist of words, names, designs, logos, slogans, sounds, scents, or a combination. Registration in the Trademarks Register (Canadian Intellectual Property Office) provides nationwide exclusivity and the presumption of validity.

Use is essential to maintaining trademark rights — a trademark not used in Canada for 3 years may be expunged for non-use. Trademark infringement occurs when an unauthorized party uses a confusingly similar mark in the same or related goods/services. Dilution (a broader form of protection for famous marks) is actionable under the Trademarks Act.

5.3.4 Trade Secrets

A trade secret is confidential business information — a formula, process, customer list, business method, or other information — that provides a competitive advantage. Unlike patents, trade secrets do not expire, but they require active measures to maintain secrecy. Disclosure (without breach of confidence) ends protection.

Protection arises through:

  • Contractual confidentiality obligations in employment agreements and supplier/customer NDAs
  • The common law duty of confidence (equitable in origin): a party who receives confidential information in circumstances importing an obligation of confidence cannot misuse or disclose it

Employee duty of confidentiality: Employees have an implied duty not to disclose their employer’s confidential information during and after employment. Specific post-employment obligations should be set out in written confidentiality agreements.


Chapter 6: Employment and Professional Relationships

6.1 Employee vs. Independent Contractor

The distinction between an employee and an independent contractor has major legal consequences:

IssueEmployeeIndependent Contractor
Employment standardsProtected by ESA (minimum wage, overtime, notice)Not protected
Human rightsProtectedProtected (under service provider rules in some contexts)
Vicarious liabilityEmployer liable for employee’s tortsPrincipal generally not liable
Source deductionsEmployer must withhold income tax, CPP, EIContractor remits own taxes
Wrongful dismissalCommon law and ESA applyOnly contractual remedies
BenefitsEmployer typically provides benefitsContractor provides own

Courts apply a multi-factor test (Sagaz Industries Canada Inc. v. 671122 Ontario Ltd. [2001] 2 SCR 983) asking: whose business is it? Factors include:

  • Control: Does the company direct when, where, and how the work is done?
  • Ownership of tools and equipment: Who provides the tools?
  • Chance of profit / risk of loss: Can the worker profit or lose money as a business person?
  • Integration: Is the work integral to the company’s core business (employee), or is it provided as an external business service (contractor)?

No single factor is determinative. Courts and the CRA look at the totality of the relationship. Misclassification of employees as contractors carries significant liability: back taxes, penalties, ESA claims, EI and CPP arrears.

6.2 Employment Standards

Provincial Employment Standards Acts (ESA) — and the federal Canada Labour Code for federally regulated industries — establish minimum conditions for employees. These are floors, not ceilings; the employment contract can provide better terms but not worse.

Key ESA entitlements (Ontario — Employment Standards Act, 2000, SO 2000, c. 41):

  • Minimum wage: Set by regulation; as of 2024, $16.55/hr (general)
  • Hours of work: Maximum 8 hours/day, 48 hours/week without agreement; averaging provisions available by agreement
  • Overtime pay: 1.5× regular rate for hours over 44/week (Ontario); overtime averaging available with employee agreement
  • Vacation: Minimum 2 weeks of vacation (or 4% vacation pay) after each year of employment; 3 weeks (6%) after 5 years
  • Public holidays: 9 public holidays per year; employees entitled to the holiday off with public holiday pay, or to substitute holiday and premium pay
  • Pregnancy and parental leave: Up to 17 weeks of pregnancy leave and up to 61 weeks of parental leave (top-up with Employment Insurance benefits available)
  • Personal emergency leave / sick days: 3 days of paid sick leave; additional unpaid leaves available
  • Termination notice: Minimum notice periods based on years of service (1 week per year, up to 8 weeks)
  • Severance pay: Separate from notice; payable when an employee has 5+ years of service and the employer has a $2.5M payroll or is severing 50+ employees in 6 months. Calculated at 1 week per year of service, up to 26 weeks.

6.3 Wrongful Dismissal

Canadian law provides that employment may be terminated:

6.3.1 Dismissal for Cause (Summary Dismissal)

An employer may dismiss an employee without notice or pay in lieu only for just cause — serious misconduct or incompetence that fundamentally undermines the employment relationship. The standard is high. Examples:

  • Theft or fraud from the employer
  • Serious insubordination
  • Gross negligence or gross incompetence (after warnings and opportunity to improve)
  • Sexual harassment of colleagues

A single incident of misconduct may or may not constitute just cause, depending on severity and context. Courts require proportionality: is dismissal a proportionate response to the wrongdoing? (*McKinley v. BC Tel [2001] 2 SCR 161 — the SCC adopted a contextual approach to just cause for dishonesty)

6.3.2 Dismissal Without Cause — Reasonable Notice

An employer may always dismiss a non-unionized employee without cause, provided reasonable notice (or pay in lieu) is given. The ESA sets minimum notice periods. The common law provides a separate, additional entitlement to reasonable notice at common law, which is substantially longer:

The common law Bardal factors (Bardal v. Globe & Mail Ltd. (1960) 24 DLR (2d) 140) for determining reasonable notice:

  • Length of service (the most important factor)
  • Character of employment (seniority, responsibility)
  • Age of the employee
  • Availability of similar employment in the market

Common law notice periods can range from a few months for junior short-service employees to 24 months or more for long-service senior managers. The common law entitlement can be reduced or eliminated by a clear contractual provision that limits notice to the ESA minimum — provided the clause is drafted clearly and was properly communicated to the employee.

6.3.3 Constructive Dismissal

A constructive dismissal occurs when the employer unilaterally makes a fundamental change to the essential terms of employment, and the employee is entitled to treat this as a termination and claim reasonable notice or pay in lieu. Examples:

  • Significant reduction in compensation or benefits
  • Demotion to a substantially inferior position
  • Relocation to a distant city without reasonable justification
  • Making the workplace so hostile that no reasonable person would stay

The employee must act promptly upon discovering the constructive dismissal. Continuing to work without objection for a prolonged period may constitute acquiescence.

6.4 Human Rights in Employment

The Canadian Human Rights Act (federal) and provincial human rights codes (e.g., Ontario’s Human Rights Code, RSO 1990, c. H.19) prohibit discrimination in employment on protected grounds. Protected grounds in Ontario include:

race, ancestry, place of origin, colour, ethnic origin, citizenship, creed, sex (including pregnancy and breastfeeding), sexual orientation, gender identity, gender expression, age, marital status, family status, disability, record of offences.

The duty to accommodate requires employers to modify workplace rules, practices, or conditions to meet the needs of an employee or applicant with a protected characteristic, up to the point of undue hardship (assessed by reference to cost, health, safety, and other factors). Accommodation is a collaborative process — the employee must participate and provide information to facilitate accommodation.

Harassment: Employers have a legal obligation to maintain a harassment-free workplace. Harassment on any prohibited ground (including sexual harassment) constitutes a human rights violation. Employers may be held vicariously liable for harassment by supervisors and, in some circumstances, by co-workers.

6.5 Agency Law

An agent is a person who has authority to act on behalf of a principal, creating legal relationships between the principal and third parties. Agency underpins virtually all business activity: corporations act only through agents (directors, officers, employees); sales transactions involve agents; real estate, banking, insurance, and investment transactions involve agents.

6.5.1 Types of Authority

Actual authority: Authority actually conferred on the agent by the principal. It may be express (explicitly stated — in a contract, board resolution, or verbal instruction) or implied (necessarily incidental to the express authority — for example, an agent expressly authorized to sell goods has implied authority to give warranties customary in the trade).
Apparent (ostensible) authority: Authority that the principal's words or conduct lead a third party to reasonably believe the agent has, even if no actual authority was conferred. The principal is estopped (prevented) from denying the agent's authority to a third party who reasonably relied on the appearance of authority. This protects innocent third parties who deal in good faith.
Example — Apparent authority: A corporation holds out its CFO as having authority to approve contracts up to \$500,000. The CFO's actual authority is limited to \$200,000. She signs a \$400,000 contract with a supplier. The corporation is bound, because the supplier reasonably relied on the apparent authority created by the corporation's own conduct. The corporation can discipline or seek indemnity from the CFO internally, but cannot deny the contract to the innocent supplier.

Ratification: A principal may retrospectively ratify (adopt) an agent’s unauthorized act, binding the principal as if the authority had existed at the time. Requirements: the principal must have existed at the time of the act (companies cannot ratify pre-incorporation contracts under the common law — see CBCA s. 14 for the statutory solution), must have had legal capacity, and must ratify the whole act.

6.5.2 Disclosed and Undisclosed Principals

  • Disclosed principal: The third party knows they are dealing with an agent and knows (or can ascertain) who the principal is. The contract is between the third party and the principal; the agent drops out and is not personally liable (unless they guarantee the contract or act fraudulently).
  • Undisclosed principal: The third party believes they are dealing with the agent as principal and does not know of the agency. When the principal is later revealed, the third party can elect to sue either the agent or the principal. The principal can enforce the contract against the third party. This doctrine has important commercial applications.

6.5.3 Agent’s Duties — Fiduciary Obligations

An agent owes fiduciary duties to the principal:

  • Duty to act in the principal’s best interests — not for personal benefit at the principal’s expense
  • Duty to avoid conflicts of interest — must not place themselves in a position where their personal interest conflicts with the duty owed to the principal, without disclosure and consent
  • Duty not to make secret profits — any profit made in connection with the agency must be disclosed and, if unauthorized, must be paid over to the principal
  • Duty of confidentiality — must not misuse the principal’s confidential information

Chapter 7: Credit and Negotiable Instruments

7.1 Credit and the Role of Security

Business credit — whether trade credit, bank loans, bond issuances, or lease financing — is the lifeblood of commerce. A lender or credit grantor seeks to ensure repayment by obtaining security over the debtor’s assets. If the debtor defaults, the secured creditor can realize on the security (seize and sell assets) to recover the debt, without the need to share in the debtor’s general insolvency proceedings.

Types of credit security:

  • Secured by real property: Mortgages and charges over land
  • Secured by personal property: Security interests under the PPSA (inventory, equipment, accounts receivable, intellectual property)
  • Personal guarantees: Guarantor (often a shareholder or director) promises to pay if the principal debtor defaults

7.2 Negotiable Instruments

A negotiable instrument is a signed, written document that contains an unconditional promise or order to pay a fixed sum of money — and that, by virtue of its negotiability, can be transferred to a new holder who acquires good title free of defects in the transferor’s title.

The Bills of Exchange Act, RSC 1985, c. B-4 (federal) governs negotiable instruments in Canada:

Promissory note: A written, unconditional promise by one party (the maker) to pay a specified sum of money to another party (the payee) at a specified time or on demand. Promissory notes are commonly used in loan transactions, real estate mortgages, and commercial credit.
Bill of exchange: A written order by one party (the drawer) directing another party (the drawee) to pay a fixed sum to a third party (the payee) or to the drawer. A cheque is a bill of exchange drawn on a bank, payable on demand.
Holder in due course: A person who takes a negotiable instrument for value, in good faith, and without notice of any defect, prior claim, or dishonour. A holder in due course takes the instrument free of most personal defences that the maker might assert against the original payee — making negotiable instruments highly liquid and commercially reliable.

7.3 Bankruptcy and Insolvency

When a business cannot pay its debts as they fall due, Canadian insolvency law provides two principal statutory frameworks:

Bankruptcy and Insolvency Act (BIA), RSC 1985, c. B-3:

  • Voluntary assignment into bankruptcy (by the debtor) or involuntary (petition by creditors owed $1,000+)
  • A trustee in bankruptcy is appointed to take possession of the debtor’s property, liquidate it, and distribute the proceeds to creditors
  • The bankruptcy order discharges the debtor (individual) from most pre-bankruptcy debts

Companies’ Creditors Arrangement Act (CCAA), RSC 1985, c. C-36:

  • Available to corporations with debts exceeding $5 million
  • Allows court-supervised restructuring while the company continues to operate
  • A “stay of proceedings” prevents creditors from taking enforcement action while the company negotiates a plan of arrangement
  • The plan must be approved by a majority in number and two-thirds in value of each class of creditors, and then sanctioned by the court

Priority of creditors in a bankruptcy or insolvency proceeding:

  1. Secured creditors (as to their collateral)
  2. Super-priority claims: government deemed trusts (source deductions, GST/HST held in trust for CRA), wage-earner protection (up to $2,000 in unpaid wages)
  3. Preferred unsecured creditors (certain wages, landlord claims)
  4. Ordinary unsecured creditors (trade creditors, bank loans without security)
  5. Shareholders (subordinate to all creditors)

Chapter 8: Securities Regulation

8.1 Overview of Canadian Securities Regulation

Securities regulation in Canada is primarily provincial and territorial — each province and territory has its own securities commission (e.g., the Ontario Securities Commission, the British Columbia Securities Commission, the Autorité des marchés financiers in Quebec) and securities legislation (Securities Act). The Canadian Securities Administrators (CSA) is an umbrella organization that coordinates national rules and instruments.

Unlike the United States, Canada does not have a single federal securities regulator, though a Cooperative Capital Markets Regulatory System has been developed among participating jurisdictions (Ontario, British Columbia, and others).

8.2 Public Markets and Continuous Disclosure

A company that distributes its securities to the public must file a prospectus — a full, true, and plain disclosure document — and obtain receipts from the relevant securities commissions. Once a reporting issuer, the company is subject to continuous disclosure obligations:

  • Annual financial statements (audited) and management’s discussion and analysis (MD&A)
  • Quarterly financial statements (interim financial reports)
  • Annual information form (AIF)
  • Material change reports: any change in the business, operations, or capital of the issuer that would reasonably be expected to have a significant effect on the market price of a security must be disclosed promptly (generally within 2 business days)
  • Management information circular (for shareholder meetings with proxy solicitation)
Civil liability for misrepresentation in disclosure documents: Investors who acquire securities in a prospectus distribution and suffer loss due to a misrepresentation in the prospectus have a statutory right of action against the issuer, directors, officers, underwriters, and experts (auditors, lawyers). This secondary market civil liability applies to misrepresentations in continuous disclosure documents — a reporting issuer and its responsible officers and directors can face significant statutory civil liability for false or misleading disclosure.

8.3 Insider Trading

Insider trading involves trading in a company’s securities while in possession of material non-public information (MNPI) about that company. It is prohibited because it undermines market integrity and investor confidence.

Material non-public information (MNPI): Information that has not been generally disclosed and that a reasonable investor would consider important in making an investment decision. Examples: upcoming merger or acquisition, earnings results significantly different from analyst expectations, a major contract win or loss, a product recall, regulatory approval or rejection.

Who is an insider? Under Ontario’s Securities Act, an “insider” includes officers and directors of the issuer, persons who own more than 10% of voting securities, and persons who receive MNPI in a special relationship with the issuer (auditors, lawyers, bankers, family members who receive tips).

Consequences of insider trading:

  • Regulatory sanctions: Suspension of trading, disgorgement of profits, administrative penalties (the OSC can impose penalties up to $1 million per offence and order disgorgement)
  • Criminal liability: Under the Criminal Code (ss. 382.1 and 380), insider trading and market manipulation are criminal offences carrying imprisonment up to 14 years
  • Civil liability: The Securities Act provides a cause of action to persons who traded on the other side of the insider’s trade

The “tipping” prohibition: It is also illegal to communicate MNPI (tip) to another person who then trades or recommends trading on the basis of the information. Both the tipper and the tippee face liability.

8.4 Market Manipulation and Fraud

Securities legislation also prohibits:

  • Market manipulation: Trading or other conduct intended to create a false or misleading appearance of trading activity or an artificial price for a security
  • Securities fraud: Engaging in a course of conduct that the person knows is likely to artificially increase or decrease the price of a security

These offences apply to a broad class of persons, not just registered insiders.


Chapter 9: Professional Liability and Ethics

Professional accountants in Canada (CPAs) operate within a web of legal obligations arising from: the law of contract (the engagement letter), the law of torts (negligence and negligent misrepresentation), securities legislation (continuous disclosure obligations and statutory civil liability), and professional regulation (CPA Ontario Rules of Professional Conduct). Understanding these overlapping obligations is essential for practitioners.

9.2 Engagement Letters and Contractual Obligations

An accountant’s engagement with a client is contractual in nature. The engagement letter defines:

  • The scope of services to be provided
  • The applicable standards (GAAP, GAAS, CPA Canada Handbook standards)
  • The limitations on the accountant’s role
  • Reporting deliverables and timelines
  • Fees
  • Limitations on liability (subject to applicable law — professional liability cannot always be contractually limited below the statutory minimum)

A clear, comprehensive engagement letter is the first line of risk management for practitioners. It defines the scope of duty and sets out expectations in writing, reducing the risk of scope creep and disputed obligations.

9.3 The Duty of Confidentiality

Accountants owe a strict duty of confidentiality to clients, arising in contract (the engagement agreement), by professional regulation (CPA Ontario Rule 208), and at common law (the equitable duty of confidence). This means:

  • Client information cannot be disclosed to third parties without the client’s consent
  • Client files cannot be shared without authorization
  • Confidentiality continues after the engagement ends

Exceptions: Confidentiality must be breached in limited circumstances:

  • Legal compulsion (court order, subpoena, regulatory demand)
  • Mandatory reporting under anti-money laundering legislation (Proceeds of Crime (Money Laundering) and Terrorist Financing Act)
  • Reporting under securities legislation (for public company auditors, certain obligations to report to audit committees)

9.4 Liability to Third Parties — The Expanding Duty of Care

Following Hercules Management, the scope of auditors’ duty of care to third parties (shareholders, creditors, investors) is limited. Auditors can reduce exposure by:

  • Clearly defining the intended users of the financial statements in the engagement letter
  • Including appropriate disclaimer language (without disclaimer language that is disproportionately broad)
  • Following professional standards meticulously and documenting the audit work

However, where an auditor addresses a report specifically to a named third party (e.g., a lender conducting due diligence), the proximity required for a duty of care may exist and the auditor may owe that third party a duty of care.

9.5 Anti-Money Laundering Obligations

The Proceeds of Crime (Money Laundering) and Terrorist Financing Act (PCMLTFA), SC 2000, c. 17, imposes obligations on certain reporting entities — including accounting firms performing specific financial services — to:

  • Identify clients (Know Your Client — KYC requirements)
  • Keep records of transactions and client identification
  • Report suspicious transactions and large cash transactions to FINTRAC (Financial Transactions and Reports Analysis Centre of Canada)

Failure to comply can result in significant administrative penalties and criminal liability. For accounting students, understanding AML obligations is increasingly part of professional competence in audit, assurance, and advisory services.


Chapter 10: Contract Law in Practice — Drafting and Risk Management

10.1 The Anatomy of a Commercial Contract

A well-drafted commercial contract typically includes:

  1. Recitals: Background and context (the “whereas” clauses), not legally operative but useful for interpretation
  2. Definitions: Defined terms used throughout the agreement (reduce ambiguity and length)
  3. Operative provisions: The core obligations of each party — what each is promising to do or not do
  4. Conditions precedent: Events that must occur before obligations arise (e.g., receipt of regulatory approval, completion of due diligence)
  5. Representations and warranties: Statements of fact as at the date of the contract (or closing), with consequences if false
  6. Covenants: Ongoing obligations during the term
  7. Indemnification clauses: One party agrees to compensate the other for specified losses
  8. Limitation of liability clause: Caps the maximum liability of one or both parties
  9. Dispute resolution clause: Specifies how disputes will be resolved (negotiation, mediation, arbitration, litigation; governing law; jurisdiction)
  10. Term and termination: Duration of the contract and conditions for early termination
  11. General provisions (boilerplate): Choice of law, entire agreement, severability, waiver, notices, counterparts, assignment

10.2 Representations and Warranties in Business Transactions

In mergers and acquisitions, real estate transactions, and major commercial deals, the representations and warranties (R&W) section is often the most heavily negotiated. The seller makes statements about the state of the business or property; if any statement is false, the buyer has a claim for breach of warranty (in contract) or misrepresentation (in tort).

Indemnification: A seller who makes representations and warranties typically also agrees to indemnify the buyer for losses arising from breaches. The indemnification provisions include:

  • A basket (deductible): The buyer can only claim indemnification if losses exceed a threshold
  • A cap: Maximum aggregate indemnification liability (often the purchase price)
  • Survival period: How long after closing the R&W can be sued upon (typically 12–24 months for general R&W; longer for fundamental representations like title and authority)
  • Representations and warranties insurance: A third-party insurer covers the buyer’s losses from R&W breaches, reducing reliance on the seller’s covenant to pay

10.3 Resolving Contract Disputes — Practical Considerations

When a contract dispute arises, the practical sequence is:

  1. Read the contract carefully: What are the precise obligations? Is there a dispute resolution clause? A limitation of liability clause? A notice requirement for claims?
  2. Preserve evidence: Collect correspondence, emails, records of performance and non-performance
  3. Give notice: Many contracts require written notice of breach within a specified period; failure to give timely notice can waive the claim
  4. Consider your remedies: Are you seeking damages, specific performance, rescission? What are you actually trying to achieve?
  5. Attempt negotiation: Most commercial disputes settle; litigation is expensive and uncertain
  6. Consider ADR: Is arbitration required by the contract? Is mediation practical?
  7. Assess limitation periods: Every civil claim must be brought within the applicable limitation period or it is barred. In Ontario, the Limitations Act, 2002 establishes a basic two-year limitation period from the date the claim was discovered (or ought to have been discovered). Missing the limitation period is catastrophic — even a meritorious claim is lost.
Limitation periods for accounting students: The two-year basic limitation period in Ontario runs from the date the claimant knew (or ought to have known) that: (1) the injury occurred; (2) the injury was caused by an act or omission; and (3) the act or omission was that of the person against whom the claim is made. In professional liability claims against accountants or auditors, identifying when the client "ought to have known" about the negligence is often a critical and contested issue.
