The leader of the Official Opposition (French: chef de l'Opposition officielle) is the member of Parliament (MP) who leads the Official Opposition in Canada. This is typically the leader of the party possessing the most seats in the House of Commons that is neither the governing party nor part of a governing coalition.

Andrew Scheer, MP for Regina—Qu'Appelle, is the current leader of the Official Opposition. The Official Opposition caucus – members of Parliament from the Conservative Party – selected Scheer as their parliamentary leader on May 6, 2025, after party leader Pierre Poilievre lost his seat in the 2025 federal election.^[2] Scheer previously served as leader of the Official Opposition from 2017 to 2020, when he was party leader.^[3]

The office should not be confused with Opposition House leader, who is a frontbencher charged with managing the business of the Opposition in the House of Commons and is formally titled Leader of the Opposition in the House of Commons. There is also a leader of the Opposition in the Senate, who is usually of the same party as the leader of the Opposition in the house.
