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.

Trump’s truculence has infuriated many Canadians, leading many to cancel U.S. vacations, refuse to buy American goods and possibly even vote early — a record 7.3 million Canadians cast ballots before election day. Trump also put Poilievre and the Conservative Party on the back foot after they appeared headed for an easy victory only months ago.

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.
