2025 Ontario general election

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 was anticipated to be held on June 4, 2026. However, it had 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, at that time, the federal Conservative Party under Pierre Poilievre was considered extremely likely to win. This speculation was fueled in May 2024, when Ford refused to commit to the June 2026 date when asked by reporters at multiple press conferences for confirmation. This speculation 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. Electoral districts 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. ==Timeline==

Contests 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 the newly re-elected President Donald Trump. A video taken on the day of the 2024 US presidential election was later released showing Ford stating that he was "100% happy" that Trump won, until Trump threatened tariffs on Canada.
