The 32nd Canadian Parliament was in session from April 14, 1980, until July 9, 1984. The membership was set by the 1980 federal election on February 18, 1980, and it only changed slightly due to resignations and by-elections prior to being dissolved before the 1984 election. It was controlled by a Liberal Party majority, led first by Prime Minister Pierre Trudeau and the 22nd Canadian Ministry, and then by Prime Minister John Turner and the 23rd Canadian Ministry. The Official Opposition was the Progressive Conservative Party, led first by Joe Clark, and then Brian Mulroney.
