Leader of the Official Opposition (Ontario)

The leader of the Official Opposition (French: chef de l'Opposition officielle) is the leader of the largest political party in the Legislative Assembly of Ontario that is not in government and is typically the second-largest party. The position is formally titled the leader of His Majesty's Loyal Opposition (French: chef de la loyale opposition de Sa Majesté); under the Westminster system, while the parliamentary opposition opposes the incumbent government, it remains loyal to the Crown and thus to Canada.
