Jean Chrétien in the context of "Lester B. Pearson"

Patriation is the political process that led to full Canadian sovereignty, culminating with the Constitution Act, 1982. The process was necessary because, at the time, under the Statute of Westminster, 1931, and with Canada's agreement, the British Parliament retained the power to amend Canada's British North America Acts and to enact, more generally, for Canada at the request and with the consent of the Dominion. That authority was removed from the UK by the enactment of the Canada Act, 1982, on March 29, 1982, by the Parliament of the United Kingdom, as requested by the Parliament of Canada.

A proclamation bringing the Constitution Act, 1982, into effect was signed by Elizabeth II, as Queen of Canada, Prime Minister Pierre Trudeau, and Minister of Justice Jean Chrétien on April 17, 1982, on Parliament Hill in Ottawa. The patriation process saw the provinces granted influence in constitutional matters and resulted in the constitution being amendable by Canada only and according to its amending formula, with no role for the United Kingdom.

The Controlled Drugs and Substances Act (French: Loi réglementant certaines drogues et autres substances) is Canada's federal drug control statute. Passed in 1996 under Prime Minister Jean Chrétien's government, it repeals the Narcotic Control Act and Parts III and IV of the Food and Drugs Act, and establishes eight Schedules of controlled substances and two Classes of precursors. It provides that "The Governor in Council may, by order, amend any of Schedules I to VIII by adding to them or deleting from them any item or portion of an item, where the Governor in Council deems the amendment to be necessary in the public interest."

The Act serves as the implementing legislation for the Single Convention on Narcotic Drugs, the Convention on Psychotropic Substances, and the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances.
