of the incorporated municipality. A municipality may apply for city status anytime after its

population surpasses 10,000. Not all municipalities which reach this population target have

pursued city designation (as, for example, Markham, Ajax and Oakville). Once designated a

city, however, a municipality does not lose this status even if its population later falls

back below 10,000 (as, for example, Dryden.)

City status may also be conferred on some rural counties which have been amalgamated such that

all municipal governance takes place at the county level with no further municipal

subdivisions. Thus, city status in Ontario does not always connote a primarily urbanized

community.

The Ministry of Municipal Affairs and Housing is responsible for laws surrounding the

incorporation and administration of municipal governments in Ontario.
