By-elections to the 45th Canadian Parliament may be held to fill vacancies in the House of Commons of Canada between the 2025 federal election and the 46th federal election. The 45th Canadian Parliament has existed since 2025 with the membership of its House of Commons having been determined by the results of the Canadian federal election held on April 28, 2025. The Liberal Party of Canada has a minority government during this Parliament. The Conservative Party of Canada forms the Official Opposition.

One by-election has been held during the 45th Parliament. It took place in the electoral district of:

• Battle River—Crowfoot, following Conservative MP Damien Kurek's announcement of his pending resignation of his seat on May 2, 2025 to give Pierre Poilievre, the leader of the Conservative Party, an opportunity to re-enter parliament after Poilievre lost his seat in the federal election. ^[1] Kurek officially resigned on June 17, 2025 and the by-election has been called for August 18, 2025. ^[2]

A writ for a by-election must be dropped no sooner than 11 days and no later than 180 days after the chief electoral officer is officially notified of a vacancy via a warrant issued by the Speaker. Under the Canada Elections Act , the minimum length of a campaign is 36 days between dropping the writ and election day, but must not exceed 50 days and the by-election must occur on a Monday within that time-frame. ^{[3] [4]}

August 18, 2025 by-election

Battle River—Crowfoot

A by-election was called in the federal riding of Battle River—Crowfoot, and was held on August 18, 2025, following the resignation of Conservative MP Damien Kurek. Kurek, who secured re-election with over 80% of the vote in the 2025 federal election on April 28, resigned his seat on June 17. This was done to allow Conservative leader Pierre Poilievre an opportunity to return to Parliament through a by-election after he was unseated in the 2025 Canadian federal election. ^{[5] [6]}

The writ for the by-election was drawn up on June 30, 2025 with the date of the vote set for August 18 in order to avoid a conflict with Alberta Heritage Day earlier in the month. ^[7]
