Timeline

2025

• February 27: The Progressive Conservative Party of Ontario under Doug Ford wins a third majority government in the 44th Ontario general election.
• September 14: Bonnie Crombie announces intention to resign as Liberal leader following a disappointing result in a leadership review vote. She will remain as leader until a leadership race chooses a successor. ^[2]
• September 20: Marit Stiles receives 68 percent support in a leadership review vote during the Ontario New Democratic Party's convention, vowing to remain as party leader. ^[3]

Ridings

The Electoral Boundaries Act, 2015 ^[4] 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, ^[5] 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. ^{[6] [7]} This was implemented through the Representation Statute Law Amendment Act, 2017. ^[8]

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 2025 provincial election. ^[9]

Ontario does not have legislation in place for a scheduled review of electoral districts and boundaries, and any changes to boundaries would require new legislation. ^[10]
