OTTAWA — Prime Minister Mark Carney is preparing to schedule an additional six byelections in the upcoming months following a series of recent resignations in the House of Commons. These changes are a crucial part of the political landscape as various Members of Parliament (MPs) step down for different reasons.
On Friday, Liberal MP Steven Guilbeault officially resigned from his seat in Laurier–Sainte-Marie, Montreal. Guilbeault's resignation is rooted in a matter of principle; he cited significant changes in the party’s direction regarding energy and environmental policies under Carney's leadership. Specifically, he opposed the decision to eliminate the consumer carbon tax and the endorsement of new pipeline constructions in Alberta.
Additionally, Conservative MP Cathay Wagantall is expected to formalize her resignation this week after announcing her plans back in June. Wagantall, who has represented Saskatchewan since 2015, initially intended to remain until the next election but later decided to leave. Nelson Pohl is set to run under the Conservative banner in her Yorkton-Melville riding during the next election.
In recent months, Guilbeault and Wagantall are part of a growing list of MPs who have exited the Commons. Notably, two MPs resigned during the summer to pursue opportunities in Quebec’s provincial elections. Bloc Québécois MP Simon-Pierre Savard-Tremblay stepped down on June 19 to run for the Parti Québécois, while Alexandre Boulerice resigned his Rosemont–La Petite-Patrie seat on August 25 to run for Québec solidaire.
Ontario Conservative MP Larry Brock has also announced plans to resign on September 18 to return to his former role as a Crown prosecutor in Brantford, Ontario. Similarly, Ontario Liberal Shaun Chen resigned from Parliament on August 15, citing health complications stemming from injuries he incurred in a car accident the previous fall.
Under Canadian law, the Prime Minister is obligated to call a byelection once a seat becomes vacant, with a time frame ranging from 11 to 180 days to do so. The byelection period itself must last between 36 to 50 days, allowing for necessary preparations and campaigning in the affected ridings.
Earlier this year, the Liberals had a successful run in three byelections held in April, winning two seats in the Greater Toronto Area (GTA) and one in Quebec. These byelections were necessary to fill positions left vacant by former cabinet ministers Chrystia Freeland and Bill Blair. The Quebec byelection in Terrebonne was notably called after the Supreme Court of Canada invalidated the previous election results due to a clerical error affecting mail-in ballots.
The unfolding scenario with multiple MP resignations and the impending byelections indicates a shifting political environment as parties prepare for the electoral challenges ahead. With the Liberal party previously consolidating power through successful byelections, the impact of these changes will be closely monitored in the coming months.
