East York
In 1998, East York, along with North York, York, Scarborough, Etobicoke and Old Toronto, were amalgamated into the new "megacity" of Toronto. East York's last mayor was Michael Prue who went on to become city councillor for East York, and then a Member of Provincial Parliament for Beaches—East York in 2001. Between 2002 and 2005, the East York Civic Centre's "True Davidson Council Chamber" was used to hold the Toronto Computer Leasing Inquiry/Toronto External Contracts Inquiry.
Metropolitan Toronto
Prior to the formation of Metropolitan Toronto, the municipalities surrounding the central city of Toronto were all independent townships, towns and villages within York County. After 1912, the city no longer annexed suburbs from York Township. At times, the suburbs asked to be annexed into Toronto, but the city chose not to do so.
