List of premiers of Ontario

Dalton McGuinty is the current premier of Ontario.

This is a list of the premiers of the province of Ontario, Canada, since Confederation in 1867. Ontario uses a unicameral Westminster-style parliamentary government, in which the premier is the leader of the party that controls the most seats in the Legislative Assembly. The premier is Ontario's head of government, while the Queen of Canada is its head of state and is represented by the Lieutenant Governor of Ontario. The premier picks a cabinet from the elected members to form the Executive Council of Ontario, and presides over that body.

Members are first elected to the legislature during general elections. General elections must be conducted every four years from the date of the last election. An election may also happen if the Governing party loses the confidence of the legislature, by the defeat of a supply bill or tabling of a confidence motion.

This article only covers the time since the Canadian Confederation was created in 1867. For the premiers of Canada West from 1840 to 1867, see List of Joint Premiers of the Province of Canada. The governments of Upper Canada from 1792 to 1840 were mostly controlled by representatives of the Crown.

Notes

1. ^ Macdonald led a Coalition between the Liberal-Conservative Party and the Liberal Party.
2. ^ Resigned to lead the federal Liberal Party when the "dual mandate" rule was abolished
3. ^ Drury led a Coalition between the United Farmers Party and the Labour Party.
4. ^ Drury did not win a seat in the legislature until a 1920 by-election.
5. ^ Drew won the election for his party, but lost his own seat in High Park and resigned rather than seeking a bi-election.
6. ^ Miller's Progressive Conservatives had more seats than Peterson's Liberals in the 33rd legislature, but Peterson had the formal support of the NDP through a signed accord. The two parties defeated Miller with a Motion of no confidence immediately after the election and formed government under Peterson without an official coalition.
