1979 Canadian federal election

The 1979 Canadian federal election was held on May 22, 1979, to elect members of the House of Commons of Canada of the 31st Parliament of Canada. It resulted in the defeat of the Liberal Party of Canada after 11 years in power under Prime Minister Pierre Trudeau. Joe Clark led the Progressive Conservative Party to power but with only a minority of seats in the House of Commons. The Liberals, however, beat the Progressive Conservatives in the overall popular vote by more than 400,000 votes (40.11% to 35.89%). At 39, Clark became the youngest Prime Minister in Canadian history.
