On December 7, voters in six federal ridings across Quebec, Ontario, and Saskatchewan will head to the polls as Prime Minister Mark Carney announced byelections this past Sunday. The byelections are essential to fill vacant seats left by members who have stepped down for various reasons, including diplomatic appointments, provincial politics, or retirement.
According to a press release from the Prime Minister's Office, the byelections will take place in three ridings in Quebec: Laurier–Sainte-Marie, Rosemont–La Petite-Patrie, and Saint-Hyacinthe–Bagot–Acton. Seats in these ridings were previously occupied by the Liberal Party, the New Democratic Party (NDP), and the Bloc Québécois, respectively. The selection of candidates has begun in earnest, with a significant focus on retaining these critical positions.
One of the notable candidates is Guy Cormier, the former CEO of Desjardins Group, who will represent the Liberal Party in the Laurier–Sainte-Marie riding. Sachit Mehra, president of the Liberal Party of Canada, expressed confidence in Cormier’s ability to represent the interests of the constituents effectively. He emphasized Cormier's potential to be a "strong voice" for the people of Laurier–Sainte-Marie, particularly during this pivotal moment for both Québec and Canada. Cormier is expected to collaborate closely with Prime Minister Carney to promote economic prosperity in the region.
The byelections will also include ridings from Ontario, specifically Brantford–Brant South and Scarborough North, along with the Saskatchewan riding of Yorkton–Melville. The Scarborough North riding became vacant after Shaun Chen resigned, citing injuries from a car accident in late 2025, which hindered his ability to travel to Ottawa frequently. Following his resignation, Chen was elected as the new city councillor in his ward, marking a significant shift in his political career.
The Conservative Party, which previously held the seats in Yorkton–Melville and Brantford–Brant South, is gearing up for a competitive byelection campaign. Meanwhile, the Liberal Party aims to retain the Scarborough North seat, which was previously managed by Chen. With the recent political landscape in flux, this wave of byelections is crucial for all involved parties.
In response to the byelections, Conservative Leader Pierre Pollievre took to Twitter to encourage Canadians to opt for a different political path, outlining his party's plans to save money, protect jobs, and reform the immigration system. His statements reflect an ongoing effort by the Conservative Party to position itself as a viable alternative to the current Liberal government under Mark Carney, which has maintained a majority following three successful byelections earlier this year.
Since the 2025 election, a total of 13 out of 343 members of Parliament have decided to resign from their positions. According to parliamentary rules, the Prime Minister is required to call for an election within 11 to 180 days following a member's resignation. These byelections represent a key opportunity for political parties to reinforce their positions in Parliament while responding to the recent departures, creating an interesting political climate as Canadians prepare to head to the polls once again.
