A by-election will be held on April 13, 2026, to elect a member of Parliament (MP) to represent Terrebonne, Quebec, in the House of Commons for the remainder of the 45th Parliament after the riding's result in the 2025 general election was annulled by the Supreme Court of Canada on February 13, 2026, vacating the seat held by the then-Liberal Party MP Tatiana Auguste.
