Seats in the House of Commons

Distribution of Seats, by Political Party

When Canadians vote in federal elections, they vote for the person they want to represent their electoral district in the House of Commons. There are 338 seats in the House of Commons, one for each electoral district. The person who wins the most votes becomes the member of Parliament (MP) for their electoral district and holds the seat until the next election.
