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?

The US president came to dominate on the campaign trail, with the contest being viewed as a referendum on how Canada should engage with him.
