# 2025 Ontario general election

The 2025 Ontario general election was held on February 27, 2025, to elect the 44th Parliament of Ontario. On January 24, 2025, Premier Doug Ford confirmed that he would be asking the lieutenant governor to dissolve the legislature and call for a snap election.
The incumbent Progressive Conservative Party of Ontario (PC) government, led by Premier Doug Ford since 2018, was seeking re-election to a third consecutive term. The PC's primary opponents were the Ontario New Democratic Party (NDP) led by Marit Stiles, the Ontario Liberal Party (OLP) led by Bonnie Crombie, and the Green Party of Ontario (GPO) led by Mike Schreiner. The Progressive Conservatives led by Doug Ford were reelected with a third consecutive majority government, the first premier to do so since 1959, though with a slightly smaller majority than in 2022.
The Liberals received over ten percentage points more than the NDP in the popular vote, but received fewer seats. More specifically, the Liberals got about 61% more votes than the NDP, but the NDP got almost twice as many seats. Due to a rise of six percentage points in their portion of the popular vote, the Liberals gained five seats compared to before the election. This increase was enough to regain official party status in the legislature which the party had lost after the 2018 election. However, Liberal leader Bonnie Crombie was defeated in her riding of Mississauga East—Cooksville.
The NDP continued to hold the status of official opposition, despite losing one seat and placing a distant third in the popular vote.
The Greens held their two seats, although suffering a slight drop in popularity. Incumbent independent MPP Bobbi Ann Brady held her seat in Haldimand-Norfolk, winning the second-largest margin in the province.

## Background

Under the Ontario Elections Act, general elections must be held on the first Thursday in June in the fourth calendar year following the previous general election. As the previous election was held on June 2, 2022, this election would be held on June 4, 2026. However, it has been speculated since early 2024 that Premier Doug Ford would call a snap election to take advantage of a lead in the polls and fundraising, as well as a desire to hold the election before the next federal election, which the Conservative Party is projected to win. This speculation was fuelled in May 2024, when Ford refused to commit to the June 2026 date when asked by reporters at multiple press conferences.
On January 23, 2025, multiple news outlets reported that Ford would visit Edith Dumont, the Lieutenant Governor of Ontario, on January 29 to ask for the 43rd Provincial Parliament to be dissolved, triggering an election to be held on February 27. This was confirmed by Ford at a press conference on January 24. On January 28, he met with Dumont; the Provincial Parliament was formally dissolved, with a writ of election issued the next day. The election cost approximately $189 million.

### Ridings

The Electoral Boundaries Act, 2015 increased the number of electoral districts from 107 to 122, following the boundaries set out by the federal 2013 Representation Order for Ontario, while preserving the special boundaries of the 11 seats in Northern Ontario set out in the 1996 redistribution.
The Far North Electoral Boundaries Commission, appointed in 2016, recommended the creation of the additional districts of Kiiwetinoong and Mushkegowuk—James Bay, carved out from the existing Kenora—Rainy River and Timmins—James Bay ridings, which accordingly raised the total number of seats to 124. This was implemented through the Representation Statute Law Amendment Act, 2017.
With the 2022 Canadian federal electoral redistribution, Ontario was allotted 1 additional seat in the House of Commons. On August 1, 2024, Premier Ford announced that Ontario would break with recent tradition and not adopt the federal electoral boundary changes for the next provincial election. As Northern Ontario lost a seat in the federal process, further adjustments would have been needed to maintain their extra provincial representation, which would have resulted in an extra additional riding.

### Issues

In January 2025, Ford began to state that he would need a "clear mandate" from voters to respond to the tariffs on Canadian imports to the United States threatened by new President Donald Trump. Ford was caught on video saying that on the day of the 2024 U.S. presidential election he was "100% happy" that Trump won, until Trump threatened tariffs on Canada.
