The Globe and Mail lays out the ridings expected to hold federal byelections in the coming months, after Conservative Richard Martel and Liberal Nate Erskine-Smith resigned their seats. When a Commons seat becomes vacant, the prime minister must call a byelection between 11 and 180 days after the resignation. Included here for the NDP-relevant context around Avi Lewis’s decision not to run in any of these races.
The ridings profiled:
- Chicoutimi-Le Fjord — Martel resigned after Carney appointed him to the Senate. He had held the Quebec seat since a 2018 byelection, winning by roughly 1,500 votes in April 2025.
- Beaches-East York — Erskine-Smith, who took 67 per cent in 2025, left after his plan to seek the Ontario Liberal leadership fell through when he could not lock up a provincial nomination in Scarborough.
- North Vancouver-Capilano — Jonathan Wilkinson resigned June 19 to become Canada’s ambassador to the European Union; he won just under 60 per cent in 2025.
- Yorkton-Melville — Conservative Cathay Wagantall set an Aug. 31 resignation date; the party has already chosen a candidate. She won more than 77 per cent in 2025.
- Rosemont-La Petite-Patrie — Alexandre Boulerice, the only NDP MP in Quebec, quit the NDP caucus to sit as an Independent and plans to resign before the fall to run for Québec Solidaire. He won 41 per cent in 2025, ten points ahead of the Liberal. The Globe notes Lewis has said the party will fight to hold the seat.
- Saint-Hyacinthe-Bagot-Acton — Simon-Pierre Savard-Tremblay left the Bloc to run for the Parti Québécois, resigning from Parliament on June 19. He won by a 10-point margin in April 2025.
- Laurier-Sainte-Marie — Steven Guilbeault, who quit cabinet last November over what he called backsliding on climate action, plans to resign over the summer. He took more than 52 per cent in 2025.
