Federal byelections to be held in Ontario, Quebec and Saskatchewan on Dec. 7

Prime Minister Mark Carney has called byelections for six ridings in Ontario, Quebec, and Saskatchewan to be held on December 7. According to CBC News, the elections will provide the Liberals an opportunity to strengthen their thin majority in the House of Commons.

In Ontario, voters will elect new representatives for Brantford-Brant South and Scarborough North. Global News reports that the Brantford-Brant South seat was vacated by Conservative MP Larry Brock, who returned to the Crown prosecutor’s office. The Liberals have nominated Joy O’Donnell, while the Conservatives have nominated former mayor Kevin Davis.

Following an endorsement of local pastor Dave Carroll by Brock, Carroll is planning to run as an independent. In Scarborough North, Liberal MP Shaun Chen stepped down due to health concerns following a car crash in October 2025.

The remaining vacancies are located in Quebec and Saskatchewan. CityNews and Global News identify the Quebec ridings as Laurier—Sainte-Marie, Rosemont—La Petite-Patrie, and Saint-Hyacinthe—Bagot—Acton. Global News states Rosemont—La Petite-Patrie became vacant after NDP MP Alexandre Boulerice resigned to run for Quebec solidaire. Saint-Hyacinthe—Bagot—Acton was previously represented by Simon-Pierre Savard-Tremblay. The final riding is Yorkton-Melville in Saskatchewan.
