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 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.
