Constitution Act, 1982

The Constitution Act, 1982 (French: Loi constitutionnelle de 1982) 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, including renaming it the Constitution Act, 1867. In addition to patriating the Constitution, the Constitution Act, 1982 enacted the Canadian Charter of Rights and Freedoms; guaranteed rights of the Aboriginal peoples of Canada; entrenched provincial jurisdiction over natural resources; provided for future constitutional conferences; and set out the procedures for amending the Constitution in the future. This process was necessary because, after the Statute of Westminster, 1931, Canada allowed the British Parliament to retain the power to amend Canada's constitution, until Canadian governments could agree on an all-in-Canada amending formula. In 1981, following substantial agreement on a new amending formula, the two houses of the Parliament of Canada requested that the Parliament of the United Kingdom give up its power to amend the Constitution of Canada. The enactment of the Canada Act 1982 by the British Parliament in March 1982 confirmed the Patriation of the Constitution and transferred to Canada the power of amending its own Constitution. On April 17, 1982, Queen Elizabeth II and Prime Minister Pierre Trudeau, as well as the Minister of Justice, Jean Chrétien, and André Ouellet, the Registrar General, signed the Proclamation which brought the Constitution Act, 1982 into force.
