Overview
- Votes will be held April 13 in Scarborough Southwest, University—Rosedale and Terrebonne after the prime minister formally called three federal byelections.
- The Liberals hold 169 seats and would reach the 172-seat threshold for a majority if they sweep all three contests.
- Terrebonne is a rematch after the Supreme Court annulled a one-vote 2025 result over an uncounted mail ballot, pitting Liberal Tatiana Auguste against the Bloc’s Nathalie Sinclair-Desgagné again.
- In Toronto, the Liberals named Dr. Danielle Martin in University—Rosedale and former Ontario NDP deputy leader Doly Begum in Scarborough Southwest, while Conservatives had not announced candidates.
- Even with three wins, governing could remain tight as the Liberal Speaker votes only to break ties, and the caucus reached 169 after recent floor crossings by Conservatives Chris d’Entremont, Michael Ma and Matt Jeneroux.
