Prime Minister Mark Carney has called three federal by-elections for August 31, 2026, setting vote dates in British Columbia, Ontario and Quebec as the governing Liberals work to hold their majority in the House of Commons.

The ridings are North Vancouver—Capilano in British Columbia, Beaches—East York in Toronto, and Chicoutimi—Le Fjord in Quebec's Saguenay region. Carney issued the writs — the formal documents that launch an election — through a Sunday news release on July 26, 2026. Elections Canada published its own notice the same day confirming the writs were issued and that by-elections are now underway in all three constituencies. The August 31 date aligns with the earliest possible polling day Elections Canada had identified for the Chicoutimi—Le Fjord vacancy, set out in a July 9 press release.

The three seats opened through different departures. In North Vancouver—Capilano, former Liberal MP Jonathan Wilkinson resigned. In Beaches—East York, former Liberal MP Nathaniel Erskine-Smith left the seat. In Chicoutimi—Le Fjord, former Conservative MP Richard Martel vacated the riding after being appointed to the Senate. Elections Canada had flagged the Chicoutimi—Le Fjord vacancy in early July, noting the earliest available by-election date as Monday, August 31.

The stakes for the government are straightforward. The Liberals need to win at least one of the three seats to maintain their majority in the House of Commons. Losing all three would narrow or eliminate the government's working margin, depending on current seat counts and standing vacancies. The by-elections therefore function as a partial test of the Carney government's electoral standing roughly a year and a half into its mandate.

The Liberal Party has nominated candidates in all three ridings. In North Vancouver—Capilano, the candidate is Braeden Caley, who served as deputy chief of staff to Carney before seeking the nomination. Candidate identities for the other two ridings were not specified in the July 26 announcement. Conservative and Bloc Québécois candidates had not been named in the available reporting as of the writ drop.

The choice of ridings spans three provinces and three distinct political landscapes. North Vancouver—Capilano sits in a Lower Mainland corridor where the Liberals and Conservatives have traded seats in recent cycles. Beaches—East York, in east-end Toronto, has been a reliably Liberal seat under Erskine-Smith. Chicoutimi—Le Fjord, in the Saguenay, is a three-way riding where the Bloc Québécois, Conservatives and Liberals have all been competitive. Martel held it for the Conservatives, and a Senate appointment in exchange for vacating a sitting seat is a device that frees a riding for a by-election while rewarding the incumbent with a chamber seat.

The broader context here is a government managing a narrow majority in what amounts to minority-adjacent arithmetic — meaning the gap between governing and losing confidence is thin enough that each vacant seat matters. By-elections in the summer and early fall tend to draw low turnout, which can produce results that diverge from general-election patterns. For the Liberals, holding Beaches—East York is the baseline expectation; a loss there would signal trouble in the party's Toronto core. North Vancouver—Capilano, with a former senior PMO staffer as the candidate, tests whether the Carney brand carries weight in a competitive B.C. riding. Chicoutimi—Le Fjord is the most volatile of the three, and the Bloc's campaign capacity in the Saguenay will factor heavily.

For the Conservatives, retaining Chicoutimi—Le Fjord would hold a Quebec beachhead and deny the Liberals a pickup. For the Bloc, flipping the Saguenay seat would reinforce the party's claim to nationalist seats outside Montreal. Each party has roughly five weeks of campaign time before the August 31 vote.

Elections Canada has confirmed that voter registration, candidate nomination and advance poll scheduling are now proceeding under the standard 50-day writ period for each of the three ridings.
