Patriation was subsequently confirmed by the Constitution Act, 1982, part of the Canada Act 1982. A proclamation bringing the Constitution Act, 1982 into effect was signed by Elizabeth II, as Queen of Canada, then-Prime Minister Pierre Trudeau and then-Minister of Justice Jean Chrétien on April 17, 1982, on Parliament Hill, in Ottawa. The queen's constitutional powers over Canada were not affected by the act. Canada has complete sovereignty as an independent country, however, and the Queen's role as monarch of Canada is distinct from her role as the British monarch or the monarch of any of the other Commonwealth realms.
