In what year did Canada gain full sovereignty with the Constitution Act?

The year Canada gained full sovereignty with the Constitution Act is 1982. The Constitution Act, 1982, is significant because it patriated the Canadian Constitution from the United Kingdom, which means that Canada gained full legal independence and control over its own constitution. This act included the Canadian Charter of Rights and Freedoms, which established fundamental rights and freedoms for all Canadians. Prior to 1982, while Canada had autonomy in many areas, ultimate legislative authority resided with the British Parliament. The passage of the Constitution Act allowed Canada to amend its constitution without requiring approval from the British Parliament, thereby marking a major step in Canada's development as an independent nation.
