In one of the largest landslide victories in Canadian political history, the Progressive Conservative Party (PC), led by Brian Mulroney defeated the incumbent governing Liberal Party led by Prime Minister John Turner.

Mulroney's landslide majority government win came as a result of his building of a 'grand coalition' that comprised socially conservative populists from the West, fiscal conservatives from the East, and Quebec nationalists. Mulroney's PCs won the largest number of seats in Canadian history (at 211) and his party also won the second-largest percentage of seats in Canadian history (at 74.8%), only ranking behind Progressive Conservative Prime Minister John Diefenbaker's triumph in the 1958 federal election (at 78.5%). The Liberals suffered what at that time was the worst defeat for a governing party at the federal level. This election was also the last time that the winning party received over 50% of the national popular vote.

The election marked the end of the Liberals' long dominance of federal politics in Quebec, a province which had been the bedrock of Liberal support for almost a century; they did not win a majority of Quebec seats again until three decades later in 2015.
