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.
Old Toronto
Old Toronto is the retronym of the area contained within the original boundaries of Toronto, Ontario, Canada, from 1834 to 1998. It was first incorporated as a city in 1834, after being known as the town of York, and became part of York County. In 1954, it became the administrative headquarters for the Regional Municipality of Metropolitan Toronto. The city expanded in size by annexation of surrounding municipalities, reaching its final boundaries in 1967. Finally, in 1998, it was amalgamated with the other cities of Metropolitan Toronto (York, North York, Etobicoke, Scarborough); and the borough of East York, into the present-day city of Toronto. This was not a traditional annexation of the surrounding municipalities (where a city absorbs the said municipalities but officially remains the same city), but rather a new municipal entity that is the successor of the original city.
