The 34th Canadian Parliament was in session from December 12, 1988, until September 8, 1993. The membership was set by the 1988 federal election on November 21, 1988, and it changed only somewhat due to resignations and by-elections until it was dissolved prior to the 1993 election. It was controlled by a Progressive Conservative Party majority, led first by Prime Minister Brian Mulroney and the 24th Canadian Ministry, and then Prime Minister Kim Campbell and the 25th Canadian Ministry. The official opposition was the Liberal Party, led first by John Turner, and after 1990, by Jean Chrétien.
