The Canada Act 1982 receives the Royal Assent from Queen Elizabeth II, setting the stage for the Queen of Canada to proclaim the Constitution Act, 1982.

The Canada Act 1982 is an act of the Parliament of the United Kingdom and one of the enactments which make up the Constitution of Canada. It was enacted at the request of the Senate and House of Commons of Canada to patriate Canada's constitution, ending the power of the British Parliament to amend the constitution. The act also formally ended the "request and consent" provisions of the Statute of Westminster 1931 in relation to Canada, whereby the British parliament had a general power to pass laws extending to Canada at its own request.
