Constitution Act, 1982

via *wikipedia*:

"The Constitution Act, 1982 (Schedule B of the Canada Act 1982 (UK)) is a part of the Constitution of Canada. The act was introduced as part of Canada's process of patriating the constitution, introducing several amendments^[1] to the British North America Act, 1867, and changing the latter's name in Canada to the Constitution Act, 1867. Elizabeth II, as Queen of Canada, brought the act into effect with a proclamation she signed in Ottawa on April 17, 1982.

The Canadian Charter of Rights and Freedoms forms the first thirty-five sections (counting Section 16.1 and not counting Section 35) of the Constitution Act, 1982.

As of 2015, the government of Quebec has never formally approved of the enactment of the act, though formal consent was never necessary.^[2] Nonetheless, it has remained a persistent political issue in Quebec. The Meech Lake and Charlottetown Accords were designed to secure approval from Quebec, but both efforts failed to do so."
