It was the Liberals' first election in almost thirty years not under the leadership of William Lyon Mackenzie King.

King had retired in 1948, and was replaced as Liberal leader and Prime Minister by Louis St. Laurent.

The Liberal Party victory won the largest majority in Canadian history to that point.

The Progressive Conservative Party, led by former Premier of Ontario George Drew, gained little ground in this election.
