Who became prime minister of Canada on September 17, 1984?

Martin Brian Mulroney (born March 20, 1939) is a Canadian politician who served as the 18th prime minister of Canada from September 17, 1984, to June 25, 1993. His tenure as prime minister was marked by the introduction of major economic reforms, such as the Canada-U.S. Free Trade Agreement and the Goods and Services Tax, and the rejection of constitutional reforms such as the Meech Lake Accord and the Charlottetown Accord. Prior to his political career, he was a prominent lawyer and businessman in Montreal.

In the general election of 1984 he ran an almost flawless campaign against Prime Minister John Turner's Liberals and won 211 seats, the largest number in Canadian history. Mulroney, who had always emphasized the importance of Québec to the Conservatives, captured the seat of Manicouagan, his home riding. His pledge to bring Québec to the Constitution "with honour and enthusiasm" was decisive in persuading many Québec nationalists to support the Conservatives. The party took 58 of its seats in the province, the breakthrough that Mulroney had promised would take place under his leadership. He was sworn in as the 18th prime minister on 17 September 1984.
