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.
York Centre
York Centre was originally created in 1903 from parts of York East and York West ridings. It was created when the county of York (excluding the city of Toronto) was divided into three ridings: York Centre, York North and York South. The centre riding consisted of the townships of Etobicoke, Markham, Scarborough and Vaughan, and the villages of Markham, Richmond Hill, Weston and Woodbridge. The electoral district was abolished in 1914 when it was redistributed between York East, York South and York West. In 1952, York Centre was re-designated with parts of Eglinton—Lawrence, Willowdale, York North and York West ridings.
