Which act formally served as the core constitutional document before patriation in 1982?

• A. The Canada Act
• B. The Constitution Act, 1982
• C. The Statute of Westminster
• D. The British North America Act (Constitution Act, 1867)

Answer: (D)

The foundational constitution for Canada prior to patriation was the British North America Act of 1867, later renamed the Constitution Act, 1867. This act created Confederation and established the federal structure, outlining the division of powers between federal and provincial governments and setting up how laws and constitutional governance would operate under the Crown. Even though Canada gained increasing independence with the Statute of Westminster in 1931, changes to the constitution still required British involvement. It wasn’t until patriation in 1982 that Canada took full control, adding the Constitution Act, 1982 and the Charter of Rights and Freedoms, and completing the shift away from reliance on British authority for constitutional amendments. Therefore, the British North America Act (Constitution Act, 1867) served as the constitution’s formal framework before patriation.
