The 1963 Ontario general election was held on September 25, 1963, to elect the 108 members of the 27th Legislative Assembly of Ontario (Members of Provincial Parliament, or "MPPs") of the Province of Ontario.^[1]

The Ontario Progressive Conservative Party, led by John Robarts, who had replaced Leslie Frost as PC leader and premier in 1961, won a seventh consecutive term in office, and maintained its majority in the legislature, increasing its caucus from the 71 members elected in the previous election to 77 members in an enlarged legislature.

The Ontario Liberal Party, led by John Wintermeyer, increased its caucus from 22 to 24 members, although Wintermeyer lost his seat of Waterloo North. He resigned as party leader but the Liberals continued in their role of official opposition. Robert Gibson of Kenora was re-elected as a Liberal-Labour MPP sitting with the Liberal caucus.

The social democratic Co-operative Commonwealth Federation was formally dissolved and succeeded by the Ontario New Democratic Party in 1961. The newly conglomerated party was still led by Donald C. MacDonald, and won two additional seats, for a total of seven.

The Social Credit Party of Ontario split into two factions mirroring the split in the federal party. The official Social Credit party ran candidates in three rural ridings while the more radical Social Credit Action faction ran candidates in six ridings in Toronto.^[2]
