Canadians will vote for a candidate from one of the political parties in their federal “riding,” or district. Whichever candidate gets the most votes in a riding will become a Member of Parliament (MP) in the House of Commons, and the party with the most MPs wins the election.

The two leading candidates, Pierre Poilievre and Mark Carney, both plan to fight the U.S., its largest trading partner, over tariffs. But who would be more successful as relations grow icy?

Conservatives once had a 25-point lead ahead of Canada's next election. That lead has since vanished. Experts say Trump's actions may changed the course of the election.
