Conservative Party leader Pierre Poilievre lost his seat in the Canadian parliament, yielding to Liberal Party candidate Bruce Fanjoy in his Ottawa constituency, according to preliminary results announced on Tuesday.

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

Conservative Leader Pierre Poilievre is projected to lose his own seat in the Canadian election, despite delivering the best result for his party since 2011.
