# 1948 Ontario general election

The 1948 Ontario general election was held on June 7, 1948, to elect the 90 members of the 23rd Legislative Assembly of Ontario (Members of Provincial Parliament, or "MPPs") of the Province of Ontario.
The Ontario Progressive Conservative Party, led by George Drew, won a third consecutive term in office, winning a solid majority of seats in the legislature—53, down from 66 in the previous election. Drew unexpectedly lost his seat, and thereafter announced that rather than return to the legislature, he would seek the leadership of the federal Progressive Conservative Party of Canada.

## Campaign

The majority of races were three-way contests:

## Outcome

Despite winning a majority, Drew lost his own seat to temperance crusader Bill Temple. Instead of seeking a seat in a by-election, Drew left provincial politics to run for, and win, the leadership of the federal Progressive Conservative Party.
Drew was replaced as Ontario PC leader and premier by Thomas Kennedy on an interim basis, and then by Leslie Frost.
The Ontario Liberal Party, led by Farquhar Oliver, increased its caucus from 11 to 14, but lost the role of official opposition. Only one of the three Liberal-Labour MPPs sitting with the Liberal caucus, James Newman, was re-elected.
The social democratic Co-operative Commonwealth Federation (Ontario Section), led by Ted Jolliffe, formed the official opposition by increasing its caucus from 8 to 21 seats.
Two Toronto seats were won by Labor-Progressive Party MPPs J. B. Salsberg and A.A. MacLeod. The LPP was the official name of the Communist Party of Ontario. The LPP only ran two candidates, Salsberg and MacLeod, in 1948 down from 31 candidates in 1945.
