List of cities in Ontario

A city is a subtype of municipalities in the Canadian province of Ontario. A city can have the municipal status of either a single-tier or lower-tier municipality. Prior to 2003, Ontario had minimum population thresholds of 15,000 and 25,000 for city status. Minimum population thresholds are no longer necessary for a municipality to brand itself as a city.
