The 1993 Canadian federal election was held on October 25, 1993, to elect members to the House of Commons of the 35th Parliament of Canada. Considered to be a major political realignment, it was one of the most eventful elections in Canada's history. Two new regionalist parties emerged, finishing second and third in seat count. Most notably, the election marked the worst defeat for a governing party at the federal level and one of the worst ever suffered by a governing party in the Western democratic world. The Liberal Party, led by Jean Chrétien, won a majority government, defeating the governing Progressive Conservative Party in a landslide. The 22.6% gap between the Liberals and the newly formed Reform Party is the largest difference between the top-two popular vote parties in Canadian federal election history.
The election was called on September 8, 1993, by the new Progressive Conservative (PC) leader, Prime Minister Kim Campbell, near the end of her party's five year mandate. When she succeeded longtime Prime Minister Brian Mulroney and assumed office on 25 June, the party was deeply unpopular due to the failure of the Meech Lake and Charlottetown Accords in 1990 and 1992, respectively, the introduction of the Goods and Services Tax in 1991, and the early 1990s recession. The PCs were further weakened by the emergence of new parties that were competing for its core supporters, including the western-based Reform Party of Canada and the Bloc Québécois advocating for Quebecois sovereignty and separatism, both of which ended up heavily splitting the PC vote.
