The 25th Canadian Parliament was in session from September 27, 1962, until February 6, 1963. The membership was set by the 1962 federal election on June 18, 1962, and it changed only somewhat due to resignations and by-elections until it was dissolved prior to the 1963 election. It was controlled by a Progressive Conservative Party minority under Prime Minister John Diefenbaker and the 18th Canadian Ministry. The Official Opposition was the Liberal Party, led by Lester B. Pearson. It was the third shortest parliament in Canadian history. The Speaker was Marcel Lambert.
