Canadians on Monday are voting to choose a prime minister who will negotiate with President Trump over trade and security, and to navigate their economy through turbulence as businesses freeze spending and hiring.

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.
