Populist Conservative leader Pierre Poilievre — in the lead until U.S. President Donald Trump took aim at Canada with a trade war and annexation threats — was voted out of his Parliament seat in Monday's election.

Pierre Poilievre, the leader of the Conservative Party, was unseated as the parliamentary representative of his Ottawa district in a stunning upset that could put his leadership of the party in question.

Poilievre losing his own seat capped off a devastating night for Canada's conservatives as they were decisively beaten in the election.
