Constitution Act, 1867

The Constitution Act, 1867 (formerly the British North America Act, 1867) is the foundational constitutional document of Canada. Enacted by the United Kingdom Parliament, it created the Dominion of Canada by uniting the provinces of Canada (Ontario and Quebec), Nova Scotia, and New Brunswick. The Act established the federal system of government, dividing legislative powers between the federal Parliament and the provincial legislatures. Sections 91 and 92 list the exclusive powers of each level of government. The Act also established the parliamentary system based on the Westminster model, the Crown, the Senate, the House of Commons, and the provincial governments. The Act has been amended numerous times, most significantly by the Constitution Act, 1982, which added the Canadian Charter of Rights and Freedoms and the amending formula.

Significance

The Constitution Act, 1867 is Canada’s founding constitutional document, establishing the federal structure that has shaped Canadian governance for over 150 years. The division of powers between federal and provincial governments has been the subject of extensive judicial interpretation by the Judicial Committee of the Privy Council (pre-1949) and the Supreme Court of Canada. Key doctrines include the ‘peace, order, and good government’ clause (POGG), the ‘aspects’ doctrine allowing dual characterization of laws, and the ‘paramountcy’ doctrine resolving conflicts between federal and provincial laws.
