It resulted in a majority victory for the incumbent Progressive Conservatives under the leadership of Premier Dufferin Roblin.

Roblin's PCs won 36 seats against 11 for the Liberal-Progressives, led by former Premier Douglas Campbell, and 10 for the social democratic Co-operative Commonwealth Federation led by Lloyd Stinson.

The election is the last one to be fought by candidates with the "Liberal-Progressive," "Co-operative Commonwealth," or "Labor-Progressive" labels in Manitoba.

The Liberal-Progressives dropped the latter half in 1961 and ran all subsequent elections as "Liberals."
