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.^[12][13]

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.^[14]

A by-election was held in the federal riding of Terrebonne in Quebec, Canada, after the Supreme Court of Canada, on February 13, 2026, reversed a lower court ruling denying an appeal by a Bloc Québécois candidate, who lost the federal election in Terrebonne riding by a single vote, vacating the seat won by Liberal MP Tatiana Auguste and triggering a byelection. The annulment was due to a printing error by Elections Canada on a return envelope for mail-in ballots which resulted in an envelope containing a vote for the Bloc Québécois candidate being returned to sender after the election.^[31]

Auguste was elected by an increased margin according to preliminary results, holding this seat for the Liberals.^[26]
