The 1945 Ontario general election was held on June 4, 1945, to elect the 90 members of the 22nd 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 second consecutive term in office, winning a solid majority of seats in the legislature—66, up from 38 in the previous election. The social democratic Co-operative Commonwealth Federation (CCF), led by Ted Jolliffe, was reduced from 34 seats to only 8.
