Ontario Election Results since 1867


The first Ontario election ended in a draw. The Liberal and Conservative parties agreed to form a Conservative-led coalition government, naming John Sandfield Macdonald premier.


The Conservatives jumped up to 69 seats and claimed their first outright victory as a party.

After 34 years of Liberal rule, the Conservatives would be in office for most of the next 30 years.


After running without a party leader, the United Farmers of Ontario formed a coalition government with the Labour Party following their victory.

The group is one of only two parties other than the Liberal and Conservative parties to ever win an Ontario election.


The Conservatives narrowly defeated the surprising Co-operative Commonwealth Party. The victory would kick off 42 years of Conservative rule in the province.

The Co-operative Commonwealth Party also became the official opposition. The party would later become the NDP in 1961 after failing to ever take office.


Despite taking only 48 seats to the Conservatives’ 52, the Liberals formed an NDP-backed minority government a month after the election, following a vote of no confidence.


The New Democratic Party, led by Bob Rae, won their first election with a dramatic swing from Liberal voters.


The Liberals took 53 seats in an election with the lowest voter turnout in history. Only 49.2 per cent of eligible voters went to the polls, dipping below the previous low of 52.5 per cent in 2007.
