Prime Minister of Canada
The prime minister of Canada is the head of government of Canada. Under the Westminster system, the prime minister governs with the confidence of a majority of the elected House of Commons; as such, the prime minister typically sits as a member of Parliament (MP) and leads the largest party or a coalition of parties. As first minister, the prime minister selects ministers to form the Cabinet.
