Constitution Acts 1867 & 1982: Complete Canadian Constitution Guide
Understand Canada's constitutional structure, the relationship between the Constitution Acts 1867 and 1982, federal and provincial powers, patriation, Charter protections, Indigenous rights and the rules for changing the Constitution.
What are the Constitution Acts 1867 and 1982?
Canada does not have a single constitutional document. The Constitution of Canada consists of written constitutional instruments, constitutional statutes and constitutional principles. Two central written statutes are the Constitution Act, 1867 and the Constitution Act, 1982. The Constitution Act, 1867 created the Canadian federal union and established institutions such as Parliament, the federal executive and provincial governments. It also allocated legislative powers between Parliament and the provinces, especially through Sections 91 and 92. The Constitution Act, 1982 became part of Canada's constitutional framework when the Constitution was patriated from the United Kingdom. It contains the Canadian Charter of Rights and Freedoms, Section 35 Aboriginal and treaty rights, Section 36 equalization and regional development commitments, and Part V's domestic constitutional amendment procedures. The two Acts should therefore be read together rather than treated as competing or replacement documents. The Constitution Act, 1867 remains a foundational constitutional statute, while the Constitution Act, 1982 added major constitutional protections and an amendment framework.
1. Constitution Act, 1867 — Confederation and Federal Structure
The Constitution Act, 1867 established Canada as a federation with a parliamentary form of government under the Crown. It established federal institutions, provincial governments and a constitutional division of legislative responsibilities. The original union on July 1, 1867 consisted of Ontario, Quebec, Nova Scotia and New Brunswick. Additional provinces and territories subsequently became part of Canada under constitutional instruments and legislation. The Act provides for the Senate and House of Commons, the federal executive, provincial constitutions, courts and the distribution of legislative powers. Its structure remains fundamental to Canadian federalism even after the Constitution was patriated in 1982.
2. Federal Institutions under the Constitution Act, 1867
The Constitution Act, 1867 establishes Canada's federal Parliament, consisting of the Senate and the House of Commons, and provides for executive authority exercised by the Governor General on the constitutional advice of ministers. The constitutional structure operates through responsible government, under which the executive is politically accountable to the elected House of Commons. The Constitution also establishes provincial executive and legislative institutions and provides constitutional rules concerning provincial offices, legislatures and courts. The Governor General and Lieutenant Governors represent the Crown constitutionally, while elected governments exercise political responsibility through the parliamentary system.
| Institution | Constitutional Role |
|---|---|
| House of Commons | Elected federal chamber and central forum for responsible government |
| Senate | Upper chamber of Parliament with constitutionally assigned legislative functions |
| Governor General | Crown representative at the federal level exercising constitutional powers according to the Constitution and conventions |
| Prime Minister and Cabinet | Political executive exercising government through responsible parliamentary government |
| Provincial legislatures | Provincial legislative institutions exercising constitutional jurisdiction |
| Lieutenant Governors | Crown representatives in the provinces exercising constitutional functions |
3. Section 91 — Federal Legislative Powers and POGG
Section 91 gives Parliament legislative authority over enumerated federal classes of subjects and also begins with the Peace, Order, and good Government language commonly called the POGG power. POGG is not merely a preamble principle; it is part of the constitutional grant of federal legislative authority. Section 91 includes federal jurisdiction over matters such as trade and commerce, taxation, defence, criminal law, bankruptcy and insolvency, naturalization and aliens, marriage and divorce, navigation and shipping, currency and banking, intellectual property and other listed subjects. The constitutional numbering contains repealed provisions and later additions, including section 1A and 2A. It is therefore misleading to describe Section 91 simply as '29 active head powers.' The legally useful description is that Section 91 enumerates classes of subjects assigned exclusively to Parliament, subject to the Constitution and judicial interpretation.
4. Section 92 — Provincial Legislative Powers
Section 92 gives provincial legislatures exclusive jurisdiction over listed classes of subjects. Important provincial powers include direct taxation for provincial purposes, provincial borrowing, provincial offices, management of provincial public lands, prisons, hospitals and charitable institutions, municipal institutions, local works and undertakings, licences for provincial or local purposes, property and civil rights in the province, and matters of a merely local or private nature. Health is therefore not best described as one single exclusive provincial constitutional head. Provincial jurisdiction includes hospitals under Section 92(7), while other health-related laws can engage several constitutional heads of power. Federal funding and federal health legislation do not automatically convert healthcare delivery into exclusive federal jurisdiction. Section 92's original Class 1 was repealed. Section 92A later added important provincial powers concerning non-renewable natural resources, forestry resources and electrical energy.
| Topic | Constitutional Framework | Important Qualification |
|---|---|---|
| Hospitals | Primarily provincial under s.92(7) | Other health legislation can engage additional constitutional powers |
| Property and civil rights | Provincial under s.92(13) | Subject to other applicable federal heads and constitutional limits |
| Municipal institutions | Provincial under s.92(8) | Municipalities derive their authority from provincial constitutional and statutory arrangements |
| Education | Provincial under s.93 | Subject to specific constitutional protections and amendments |
| Natural resources | Provincial powers include s.92A | Section 92A contains specific rules concerning natural resources, forestry and electricity |
5. Concurrent and Special Powers — Sections 92A, 93, 94A and 95
The Constitution is not limited to the simple federal-versus-provincial division in Sections 91 and 92. Several provisions create concurrent or specialized jurisdiction. Section 92A gives provinces specified legislative powers concerning non-renewable natural resources, forestry resources and electrical energy, with related federal provisions. Section 93 assigns education to the provinces, subject to the constitutional protections and historical denominational-school provisions contained in that section. Section 94A permits Parliament to legislate in relation to old age pensions and supplementary benefits while preserving provincial legislative operation in the same field. Section 95 makes agriculture and immigration concurrent subjects. Provincial immigration laws operate only so long and so far as they are not repugnant to an Act of Parliament.
| Provision | Subject | Constitutional Character |
|---|---|---|
| 92A | Natural resources, forestry and electrical energy | Special provincial powers with federal constitutional qualifications |
| 93 | Education | Provincial jurisdiction subject to constitutional protections |
| 94A | Old age pensions and supplementary benefits | Concurrent legislative framework |
| 95 | Agriculture and immigration | Concurrent federal and provincial jurisdiction |
6. Immigration under Section 95
Immigration is expressly assigned as a concurrent constitutional subject under Section 95. Both Parliament and provincial legislatures may make laws concerning immigration. However, a provincial immigration law has effect only to the extent that it is not repugnant to an Act of Parliament. This means it is inaccurate to describe immigration as an exclusively federal power. Federal legislation occupies a particularly strong constitutional position where there is a conflict with provincial immigration legislation because Section 95 itself specifies the applicable conflict rule. Modern immigration arrangements also involve federal statutes, regulations, administrative agreements and provincial programs. A provincial nominee program therefore does not mean that the province independently controls Canadian immigration as a whole.
7. Taxation — Sections 91(3) and 92(2)
The Constitution gives taxation authority to both levels of government through different provisions. Section 91(3) gives Parliament power over the raising of money by any mode or system of taxation. Section 92(2) gives provincial legislatures power over direct taxation within the province in order to raise revenue for provincial purposes. The constitutional distinction is more precise than saying simply that the federal government controls all taxation or that provinces share one identical taxation power. Courts interpret the tax heads together with the rest of the constitutional distribution of powers and the nature of the particular tax.
| Authority | Basic Constitutional Power |
|---|---|
| Federal Parliament — s.91(3) | Raising of money by any mode or system of taxation |
| Provincial legislatures — s.92(2) | Direct taxation within the province for provincial purposes |
8. Federalism Is Interpreted by the Courts
Sections 91 and 92 do not operate as isolated labels. Canadian constitutional law has developed doctrines to determine how overlapping laws should be characterized and whether both federal and provincial legislation can validly operate. Courts generally identify the true character of legislation by considering its purpose and legal and practical effects. A law is assigned to the level of government whose constitutional head of power supports its pith and substance. A single factual subject, such as health, the environment, labour or privacy, can engage more than one constitutional head of power depending on the legislation. Federal and provincial jurisdiction can therefore overlap without automatically meaning that one level has acted unconstitutionally. The Constitution creates a federal system in which different heads of power may interact.
9. Patriation and the Constitution Act, 1982
The Constitution Act, 1982 transformed Canada's constitutional framework by providing a domestic constitutional amendment procedure and entrenching constitutional rights. It includes the Canadian Charter of Rights and Freedoms, Section 35 Aboriginal and treaty rights, Section 36 equalization and regional development commitments, and Part V's amendment procedures. The Constitution was patriated through the Canada Act 1982 and the Constitution Act, 1982, which came into force on April 17, 1982. This ended the need for the United Kingdom Parliament to enact amendments to Canada's Constitution under the former arrangement.
10. Section 35 — Aboriginal and Treaty Rights
Section 35(1) recognizes and affirms the existing Aboriginal and treaty rights of the Aboriginal peoples of Canada. Section 35(2) specifies that the Aboriginal peoples of Canada include the Indian, Inuit and Métis peoples of Canada. Section 35 is not an absolute prohibition on any government interference with an Aboriginal or treaty right. Canadian constitutional jurisprudence has developed tests governing the identification, infringement and justification of claimed rights. The specific scope of a right depends on the evidence, the nature of the claimed right and the applicable jurisprudence. It is therefore inaccurate to describe Section 35 simply as a constitutional rule making federal and provincial laws incapable of affecting ancestral land or treaty claims.
11. Section 36 — Equalization and Regional Development
Section 36 of the Constitution Act, 1982 contains commitments concerning regional disparities and equalization. Section 36(2) states that Parliament and the Government of Canada are committed to the principle of making equalization payments so that provincial governments have sufficient revenues to provide reasonably comparable levels of public services at reasonably comparable levels of taxation. Section 36 should be understood as a constitutional commitment and framework provision. It should not be paraphrased as an unconditional constitutional guarantee that every resident receives identical public services or that a particular federal transfer amount is fixed permanently by the Constitution.
12. Section 52 — Constitutional Supremacy and Judicial Review
Section 52(1) provides that the Constitution of Canada is the supreme law of Canada and that any law inconsistent with the Constitution is, to the extent of the inconsistency, of no force or effect. This principle supports constitutional judicial review. Courts can determine whether federal or provincial legislation is authorized by the Constitution and whether legislation complies with constitutional rights and other constitutional requirements. The Constitution is therefore superior to ordinary federal and provincial legislation.
13. Part V — How the Constitution Can Be Amended
Part V of the Constitution Act, 1982 establishes several constitutional amendment procedures rather than one universal formula. The correct formula depends on the subject of the proposed amendment. The general procedure in Section 38 generally requires resolutions of the Senate and House of Commons plus resolutions from at least two-thirds of the provinces representing at least 50% of the population of all provinces. Section 41 requires unanimous provincial and federal consent for specified fundamental matters. Section 42 identifies subjects that must use the general formula. Section 43 applies to provisions concerning one or more but not all provinces. Section 44 gives Parliament unilateral authority over certain federal institutional matters, while Section 45 gives provincial legislatures unilateral authority to amend their provincial constitutions, subject to Section 41. Part V also contains procedural rules on initiation, Senate resolution requirements, proclamation and the time limits associated with the general procedure.
14. The 7/50 Formula in Detail
Section 38(1), the general amendment procedure, requires authorization by resolutions of the Senate and House of Commons and by the legislative assemblies of at least two-thirds of the provinces that together represent at least 50% of the population of all the provinces according to the latest general census. The formula is commonly called the 7/50 rule because two-thirds of Canada's ten provinces is seven provinces and the supporting provinces must collectively represent at least 50% of the population of all provinces. The formula is subject to the rest of Part V, including provisions governing provincial dissent, compensation in certain education or cultural transfers, Senate procedures and proclamation timelines.
15. Unanimity, Bilateral and Unilateral Procedures
The Constitution Act, 1982 deliberately distributes different kinds of constitutional amendments across different procedures. Section 41 is the strictest formula. It requires the Senate and House of Commons and the legislative assembly of every province for the specified matters. Section 43 applies where an amendment concerns a provision that applies to one or more, but not all, provinces. It requires federal approval and approval from every affected provincial legislature. Section 44 allows Parliament to amend the Constitution in relation to specified federal institutional matters, subject to the limits in Sections 41 and 42. Section 45 allows a province to amend its own provincial constitution, subject to Section 41.
16. Constitutional Amendment Procedure — Important Timing Rules
Part V contains procedural safeguards in addition to the voting formulas. Under the general procedure, Section 39 provides a one-year minimum period before proclamation unless every provincial legislature has previously adopted a resolution of assent or dissent, and it imposes a three-year maximum period for proclamation after the initiating resolution. Section 47 also provides a mechanism for proceeding without a Senate resolution after the constitutional conditions in that provision are satisfied. These provisions mean that constitutional amendment rules involve more than simply counting provincial approvals. The proposed amendment must also satisfy the procedure applicable to its subject matter.
17. What the Constitution Does Not Mean
The Constitution should not be reduced to a simple statement that 'Ottawa controls national issues and provinces control local issues.' Courts classify laws according to constitutional heads of power and recognize areas of overlap. Likewise, the Constitution Act, 1982 did not replace the Constitution Act, 1867. Canada's present constitutional structure is derived from multiple constitutional instruments. The Charter is part of the Constitution, but constitutional law also includes federalism, institutional arrangements, Aboriginal and treaty rights, amendment procedures and constitutional conventions and principles developed through Canadian constitutional practice and judicial decisions.
Important Legal Distinctions
The 1867 Act established the federal framework and distribution of legislative powers. The 1982 Act added the Charter, Section 35 rights, Section 36 and domestic amendment procedures. Both remain part of Canada's constitutional framework.
The Canada Act 1982 is a United Kingdom statute. The Constitution Act, 1982 is the Canadian constitutional statute that forms part of Canada's Constitution and contains the Charter and other constitutional provisions.
Federal financial support for a provincial policy area does not by itself establish exclusive federal legislative jurisdiction over that subject.
Section 95 itself provides the constitutional rule that provincial immigration laws operate only insofar as they are not repugnant to federal immigration legislation. This should be distinguished from the general federal paramountcy doctrine.
Ordinary federal or provincial legislation generally cannot change constitutional provisions in the same way as ordinary statutes. The applicable constitutional amendment procedure depends on the subject matter and may require provincial, federal or unanimous approval.
Aboriginal and treaty rights under Section 35 are constitutional rights and do not simply operate as ordinary property-law claims. Their scope and infringement are governed by constitutional jurisprudence.
