The Prime Minister's Office (PMO) is the central political office supporting the Prime Minister of Canada. The PMO advises the Prime Minister on policy, communications, appointments, and political strategy. It coordinates the government's agenda across departments, including urban and municipal affairs when they're priorities. The PMO is distinct from the Privy Council Office (PCO), which provides non-partisan public service support. PMO staff are political appointees who serve at the Prime Minister's pleasure. The Chief of Staff leads the PMO and is one of the most influential figures in government. The PMO plays a key role in determining which issues receive federal attention and resources.
