Vacant[a]



A by-election will be held in the federal riding of Scarborough Southwest in Ontario, Canada, following the announced resignation of incumbent Liberal MP Bill Blair on February 2, 2026.

Background

Early speculation

In September 2025, The Globe and Mail reported that Prime Minister Mark Carney was considering appointing former cabinet minister Bill Blair to a senior diplomatic post, with sources indicating he was being considered for the role of Canada’s High Commissioner to the United Kingdom. The report said the potential appointment was viewed as part of an effort to recognize former senior ministers and create opportunities to recruit new cabinet talent following the formation of Carney’s government.[1]

The article noted that Blair, who had served as minister of national defence and minister of public safety, had not been included in Carney’s new cabinet despite being regarded by sources as a competent minister. It also reported that his riding of Scarborough Southwest was considered a safe Liberal seat in the event a by-election were triggered by a diplomatic appointment.[1]

In January 2026, CBC News reported that Blair was among former ministers expected to receive diplomatic appointments that would require them to vacate their seats, citing prior media reporting and statements from the prime minister indicating that multiple by-elections were anticipated.[2]

Neither Blair nor his office provided public comment at the time of the reports, and no appointment timeline was announced.[1][2]

Announcement

On February 2, 2026, Prime Minister Mark Carney announced that former cabinet minister Bill Blair would resign as member of Parliament for Scarborough Southwest to accept an appointment as Canada’s high commissioner to the United Kingdom. Blair previously served as Toronto’s chief of police before being elected to the House of Commons in 2015, and later held cabinet positions including minister of public safety and minister of national defence.[3][4]

Blair’s departure resulted in a vacancy in Scarborough Southwest and marked the second Toronto-area seat to be vacated in 2026, following Chrystia Freeland’s resignation earlier in the year. The appointment filled a diplomatic vacancy created by the conclusion of Ralph Goodale’s posting in London.[3][4]

Constituency

Scarborough Southwest is an urban riding in the southwestern part of Scarborough in Toronto, encompassing the area from Lake Ontario in the south to Eglinton Avenue East in the north, and from Victoria Park Avenue in the west to Markham Road in the east. It includes the neighbourhoods of Birch Cliff, Oakridge, Cliffside, Kennedy Park, Clairlea, and Cliffcrest, as well as parts of Scarborough Village and the Golden Mile.

Timing

The Chief Electoral Officer of Canada received formal notification of the vacancy from the Speaker of the House of Commons of Canada on February 2, 2026. The date of the by-election must be announced between February 13 and August 1, 2026. The by-election must be held on a Monday, at least 36 days but no more than 50 days after the day the by-election is announced. Accordingly, the earliest date that the Scarborough Southwest by-election could be held is March 23, 2026, and the latest is September 14, 2026.[5]
