# 1951 Ontario general election

The 1951 Ontario general election was held on November 22, 1951, to elect the 90 members of the 24th Legislative Assembly of Ontario (Members of Provincial Parliament, or "MPPs") of the Province of Ontario.

## Background

Because of Canada's participation in the Korean War, and because previous legislation governing the participation of active service voters stationed overseas had lapsed, new provision was made to enable the collection of votes of Ontario residents who had returned to active service because of the present conflict. Legislation governing the functioning of elections and the preparation of voters' lists was also revised.

## Outcome

The Ontario Progressive Conservative Party, led by Leslie Frost, won a fourth consecutive term in office, increasing its caucus in the legislature from 53 in the previous election to 79—a solid majority.
The Ontario Liberal Party, led by Walter Thomson, lost six seats, but regained the role of official opposition because of the collapse of the CCF vote. Albert Wren was elected as a Liberal-Labour candidate and sat with the Liberal caucus.
The social democratic Co-operative Commonwealth Federation (CCF), led by Ted Jolliffe, lost all but two of its previous 21 seats with Jolliffe himself being defeated in the riding of York South.
One seat was won by J.B. Salsberg of the Labor-Progressive Party (which was the Communist Party of Ontario). LPP leader A.A. MacLeod lost his downtown Toronto seat of Bellwoods in this election and three other LPP candidates were also defeated.
