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.
Oakwood–Vaughan
Oakwood–Vaughan has changed political boundaries on several occasions. One of the most significant changes was the result of amalgamation in 1998. Formerly part of the City of York, York became part of the City of Toronto, along with Etobicoke, Scarborough, and North York—all cities in their own right before January 1, 1998.
