In Canadian politics, a Quebec lieutenant is a politician, usually from Quebec or at least French-Canadian, and usually a Member of Parliament or at least a current or former candidate for Parliament, who is selected by a senior politician such as the Prime Minister or the leader of a federal party, as his or her main advisor and/or spokesperson on issues specific to Quebec. This is particularly the case when the leader is an anglophone, though several francophone leaders have also had Quebec lieutenants. This is an unofficial but usually well-known assignment.
