1.1 The Canadian Legal System, Constitutional Divisions & Courts

The Canadian Legal System, Constitutional Divisions & Courts

The practice of applied science and engineering technology in Ontario operates within a well-defined legal architecture. Whether an engineering technician is conducting geotechnical soil compaction testing, or an engineering technologist is specifying HVAC distribution layouts or programming industrial automated control logic, legal rules dictate professional duties, contractual responsibilities, and liabilities. Understanding how laws are created, how legislative powers are divided, and how the Canadian judicial hierarchy interprets legal disputes provides the essential foundation for professional accountability.

What Law Is and How It Is Classified

The PPE eBook opens its law module with basic vocabulary. These terms appear in definition-style questions, so learn them exactly:

• A rule is a principle governing the conduct of members of a group. A law is a rule created and enforced by the authority of a government and the courts. The law means all of a society's laws taken together.
• The rule of law means that the law applies equally to every person in society, including governments and officials. No one is above it.
• Rights (such as freedom of speech or freedom to move within the country) and duties (such as obeying the law and paying taxes) are what laws create and enforce.

In a private-law lawsuit, the party who starts the case is the plaintiff, and the party being sued is the defendant. In a criminal prosecution, the Crown prosecutes an accused.

Where Canadian Law Comes From: The eBook's Three Sources

The eBook groups Canadian law into three sources:

1. Common law and equity: Common law grew from the decisions of the English royal courts. Those decisions became precedents that later courts follow. Equity developed when people petitioned the monarch directly for fairness that the rigid common law courts could not provide. It became a body of principles, such as injunctions, specific performance and rectification, that courts still apply alongside the common law.
2. Statute law: laws passed by an elected legislature (Parliament or a provincial legislature), such as the OACETT Act, 1998 or the Occupational Health and Safety Act.
3. Administrative law: the detailed regulations through which statutes are carried out, and the decisions of the boards, tribunals and agencies to which legislatures delegate authority, such as OHSA regulations, MLITSD inspectors' orders, and professional regulators' by-laws.

The more detailed four-part breakdown below (constitution, statutes, subordinate legislation, case law) covers the same ground. It separates the Constitution out as the supreme law that sits above all three.

1. Primary Sources of Canadian Law

Canadian jurisprudence derives from four distinct, interrelated sources: constitutional law, statutory legislation, subordinate regulations, and common law precedent.

Constitutional Law

The Constitution of Canada represents the supreme law of the nation. Under Section 52(1) of the Constitution Act, 1982, any law that is inconsistent with the provisions of the Constitution is of no force or effect to the extent of the inconsistency. The constitutional framework establishes the structure of government, enshrines the Canadian Charter of Rights and Freedoms, and divides legislative jurisdiction between the federal Parliament and the provincial legislative assemblies.

Statutory Law (Statutes or Acts)

Statutes are formal written laws enacted by elected legislative bodies—either the federal Parliament in Ottawa or the provincial Legislative Assembly of Ontario at Queen's Park. A proposed statute begins as a bill, undergoes three formal readings, is examined in legislative committee, and becomes law upon receiving Royal Assent from the Governor General (federally) or the Lieutenant Governor (provincially). Statutes override common law rules on the same subject, provided the statute falls within the enacting government's constitutional jurisdiction.

Subordinate (Delegated) Legislation

Because elected legislatures lack the time and specialized technical knowledge to draft detailed technical rules, statutes frequently delegate regulatory authority to specialized bodies, government ministries, municipal councils, or self-governing professional associations. Subordinate legislation includes regulations, orders-in-council, municipal by-laws, and professional association by-laws. For example, OACETT By-law 20, which sets out membership classes, governance, and the Registration and Professional Practice Committee's (RPPC's) power to discipline members, is made under the by-law power in section 7 of the Ontario Association of Certified Engineering Technicians and Technologists Act, 1998. The Code of Ethics and Rules of Professional Conduct are approved by OACETT's Board of Directors and given effect through By-law 20.

Common Law and Case Precedent

Common law is judge-made law developed through centuries of judicial decisions. Originating in medieval England, the common law evolves incrementally as judges apply legal principles to specific disputes. When a court decides a case, its written reasons establish a precedent. Future courts faced with similar facts must apply that precedent. Common law governs crucial areas of professional life where statutes have not fully occupied the field, including the fundamental rules of contract formation and the law of torts and negligence.

2. Constitutional Division of Legislative Powers

The distribution of law-making authority in Canada is governed primarily by Sections 91 and 92 of the Constitution Act, 1867 (formerly the British North America Act). The drafters intended to create a strong federal union while granting provinces jurisdiction over matters of local and cultural importance.

Federal Jurisdiction (Section 91)

Section 91 grants the federal Parliament authority to enact laws for the "Peace, Order, and Good Government of Canada" (the POGG power) regarding matters not assigned exclusively to the provinces, as well as specific heads of power, including:

• Regulation of Trade and Commerce (international and interprovincial trade);
• Criminal Law and procedure;
• Navigation, shipping, and federal waterways;
• Aeronautics, telecommunications, and railways connecting provinces;
• Intellectual property (patents, copyrights, trademarks, and industrial designs);
• Banking, currency, and weights and measures;
• National defence.

Engineering technologists working on federally regulated projects (such as aerodromes, interprovincial pipelines, telecommunications broadcasting towers, or nuclear facilities licensed by the Canadian Nuclear Safety Commission) must comply with federal safety regulations and technical statutes that supersede provincial enactments.

Provincial Jurisdiction (Section 92)

Section 92 assigns exclusive legislative authority to provincial legislatures over matters of a local and private nature within the province, including:

• Property and Civil Rights in the Province (Section 92(13)): This is the single most critical constitutional provision for engineering professionals. It provides the legal foundation for contract law, tort law, workplace safety (Occupational Health and Safety Act), employment standards, environmental regulation on non-federal lands, and the regulation of professions and trades.
• Municipal Institutions (Section 92(8)): Empowers provinces to create municipalities and delegate local zoning, planning, and building permit authority.
• Local Works and Undertakings (Section 92(10)): Grants authority over local construction, highways, bridges, and municipal infrastructure (unless declared by Parliament to be for the general advantage of Canada).

The Constitutional Basis for Professional Self-Regulation

Because Section 92(13) reserves "Property and Civil Rights" to the provinces, there is no single national engineering or technology licensing statute in Canada. Instead, every province and territory has enacted its own professional legislation. In Ontario, the legislature passed the OACETT Act, 1998 (a special private act) establishing OACETT as a self-governing professional association with title protection for Certified Engineering Technologists (C.E.T.) and Certified Technicians (C.Tech.). Similarly, the Professional Engineers Act governs licensed Professional Engineers (P.Eng.).

3. Canada's Bijuridical Tradition: Common Law vs. Civil Law

Canada is a bijuridical nation, operating two legal traditions concurrently.

In Ontario and all other common law jurisdictions, private law disputes regarding contracts, torts, and construction claims depend heavily on judge-made case law. In Quebec, private civil matters are governed by the codified articles of the Civil Code of Québec. However, Canadian federal statutes, criminal law, and constitutional law apply uniformly across all provinces, including Quebec.

4. The Doctrine of Stare Decisis

The bedrock of the Canadian common law system is the principle of stare decisis—a Latin phrase meaning "to stand by things decided." Stare decisis requires courts to adhere to previously established legal principles from higher courts when adjudicating cases with similar material facts.

Vertical and Horizontal Stare Decisis

• Vertical Stare Decisis: Decisions issued by higher courts are strictly binding on all lower courts within the same judicial hierarchy. A ruling of the Supreme Court of Canada binds every court across Canada. A decision of the Court of Appeal for Ontario binds all Ontario trial judges in the Superior Court of Justice and the Ontario Court of Justice.
• Horizontal Stare Decisis: Appellate courts generally follow their own prior decisions to promote legal consistency, predictability, and commercial certainty, departing from them only under exceptional circumstances where a prior ruling is proven manifestly erroneous.

Ratio Decidendi vs. Obiter Dicta

When reading a legal judgment, practitioners and legal counsel distinguish between two elements:

• Ratio Decidendi ("Reason for the Decision"): The essential legal principle, rationale, or rule of law necessary to resolve the specific dispute between the parties. The ratio decidendi constitutes the binding precedent.
• Obiter Dicta ("Remarks by the Way"): Additional commentary, observations, hypotheticals, or background musings expressed by the judge that are not strictly essential to deciding the case. Obiter remarks are persuasive but not binding on subsequent courts.

Distinguishing Cases

A trial judge is not forced to apply a precedent if the material facts of the current case differ fundamentally from the earlier decision. When a judge determines that factual differences justify applying a different legal rule, the judge is said to distinguish the precedent.

5. Court Hierarchy in Ontario and Canada

The Canadian judicial branch is organized into a hierarchical pyramid. Understanding this hierarchy is essential for knowing how engineering disputes, regulatory infractions, and disciplinary appeals move through the justice system.

1. Supreme Court of Canada (SCC)

Located in Ottawa, the Supreme Court of Canada is the final general court of appeal for all legal matters in Canada, including constitutional, criminal, administrative, and civil law disputes. Composed of nine justices appointed by the Governor General on the advice of the Prime Minister (with three justices by statute drawn from Quebec to address civil law), the SCC hears cases only by granting "leave to appeal" on matters of public importance or significant national jurisprudence.

2. Court of Appeal for Ontario (ONCA)

The Court of Appeal for Ontario is the province's highest court. It sits in Toronto and hears appeals from civil and criminal judgments rendered by the Superior Court of Justice and the Divisional Court. Decisions of the ONCA establish binding precedent across Ontario unless overturned by the Supreme Court of Canada.

3. Ontario Superior Court of Justice (SCJ)

The Superior Court of Justice is a trial court of inherent jurisdiction under Section 96 of the Constitution Act, 1867. It hears all general civil lawsuits (including contract breaches, professional negligence actions against engineering technologists, construction lien disputes, and wrongful dismissal claims) regardless of the dollar amount in controversy. The SCJ also houses two specialized branches:

• Divisional Court: An appellate branch of the SCJ that hears statutory appeals and applications for judicial review from provincial administrative tribunals, boards, and professional discipline bodies.
• Small Claims Court: Hears civil monetary claims up to $35,000. It provides an accessible, cost-effective forum for resolving minor contractor disputes, unpaid consulting fees, and property damage claims.

4. Ontario Court of Justice (OCJ)

The Ontario Court of Justice handles provincial regulatory offences and summary criminal proceedings. In the engineering and construction sector, charges under the Occupational Health and Safety Act (OHSA) or the Environmental Protection Act (EPA)—such as critical workplace injuries, trench collapses, or toxic chemical spills—are prosecuted by Crown attorneys or ministry inspectors in the OCJ. The OCJ does not have jurisdiction over private civil lawsuits.

5. Federal Courts

The Federal Court and the Federal Court of Appeal exercise specialized jurisdiction over legal matters under federal statutory jurisdiction. They adjudicate disputes concerning intellectual property (patents, registered trademarks, industrial designs, and copyright), maritime and admiralty law, citizenship and immigration, and judicial reviews of federal administrative boards and tribunals (such as the Canadian Radio-television and Telecommunications Commission or the Canadian Nuclear Safety Commission).

6. Administrative Tribunals and Professional Self-Regulation

Beyond the traditional courtroom, administrative tribunals play an indispensable role in Canadian public administration and professional governance. Tribunals are quasi-judicial bodies established by enabling legislation to resolve specialized disputes efficiently, economically, and with deep domain expertise.

Tribunals in Professional Practice

Professional regulatory bodies often act like administrative tribunals when they decide a member's rights. OACETT's discipline power is not set out in detail in the OACETT Act, 1998. The Act's objects include maintaining discipline among members (s. 2). By-law 20, s. 2.5, gives the Registration and Professional Practice Committee (RPPC) the power to reprimand, suspend, or expel a member for professional misconduct or incompetence, after notice and an opportunity to be heard. The RPPC works through two subcommittees set up in its Terms of Reference:

1. The Complaints Subcommittee (TOR102.1): Reviews complaints sent to it by the Registrar. It can refer the matter to discipline, decline to refer it, have the Registrar give the member written advice, or require that the member be cautioned or admonished.
2. The Discipline Subcommittee (TOR102.6): An ad hoc panel of at least three certified members, appointed for a specific complaint, that holds a hearing. If an allegation is proven, it can order revocation or suspension of membership, terms and conditions, a reprimand, publication of the decision, or a fine.

Principles of Natural Justice and Procedural Fairness

Administrative tribunals are not bound by the strict, formal rules of court evidence, but they are strictly bound by the principles of natural justice and procedural fairness. Every member brought before a disciplinary panel has the right to:

• Be given full, written notice of the specific allegations;
• Have a reasonable opportunity to prepare and present a defense (the right to be heard - audi alteram partem);
• Be represented by legal counsel;
• Cross-examine witnesses and inspect all documentary evidence;
• Receive a decision from an impartial and unbiased tribunal (nemo judex in sua causa);
• Receive written reasons explaining the outcome and any penalties imposed.

Judicial Review

If an administrative tribunal exceeds its statutory jurisdiction, violates procedural fairness, or issues an unreasonable decision, the affected party can apply to the courts for judicial review. In Ontario, judicial reviews of professional discipline decisions are heard by the Divisional Court of the Superior Court of Justice. Under the Supreme Court of Canada's landmark framework in Canada (Minister of Citizenship and Immigration) v. Vavilov (2019 SCC 65), courts generally review tribunal decisions on a standard of reasonableness, intervening only where the decision exhibits fatal flaws in logic, evidentiary support, or statutory interpretation.
