Conservative Party of Canada leader Pierre Poilievre has been pushed out of his Ottawa-area seat in a stunning result from Canada's 2025 federal election. Poilievre is the first Conservative leader to lose their MP seat since Kim Campbell in the 1993 federal election. However, it is far from ideal, particularly if Poilievre is to serve as an effective Leader of the Opposition. However, for Poilievre, the riding of Carleton, also previously known as Nepean-Carleton before major redistribution changes, was previously considered a safe Conservative seat. During his concession speech, Singh announced he would step down from party leadership after the NDP select an interim party leader.
