The 1984 Canadian federal election was held on September 4 of that year to elect members of the House of Commons of Canada of the 33rd Parliament of Canada. The Progressive Conservative Party, led by Brian Mulroney, won the largest landslide majority government (by total number of seats) in Canadian history, while the Liberals suffered what at that time was the worst defeat for a governing party at the federal level. Only the Progressive Conservatives faced a larger defeat, when cut to two seats in 1993.
