## History

Under the former Municipal Act, 1990, a township was a type of local municipality. Under this former legislation, a locality with a population of 1,000 or more could have been incorporated as a township by Ontario's Municipal Board upon review of an application from 75 or more residents of the locality. It also provided that a township could include "a union of townships and a municipality composed of two or more townships".
In the transition to the Municipal Act, 2001, these requirements were abandoned and, as at December 31, 2002, every township that:
* "existed and formed part of a county, a regional or district municipality or the County of Oxford for municipal purposes" became a lower-tier municipality yet retained its name as a township; and
* "existed and did not form part of a county, a regional or district municipality or the County of Oxford for municipal purposes" became a single-tier municipality yet retained its name as a township.
The current legislation also provides lower and single-tier municipalities with the authority to name themselves as "townships", or other former municipal status types such as "cities", "towns" or "villages", or generically as "municipalities".
