In 1982, Canada “patriated” its Constitution. It transferred the country’s highest law, the British North America Act(which was renamed the Constitution Act, 1867), from the authority of the British Parliament to Canada’s federal and provincial legislatures. The Constitution was also updated with a new amending formula and a Charter of Rights and Freedoms. These changes occurred after a fierce, 18-month political and legal struggle that dominated headlines and the agendas of every government in the country.
