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.
Municipal government of Toronto
Change to the legal structure came in 1954, with the creation of the Municipality of Metropolitan Toronto (known more popularly as "Metro") in 1954. This new regional government, which encompassed Toronto and the smaller communities of East York, Etobicoke, Forest Hill, Leaside, Long Branch, Mimico, New Toronto, North York, Scarborough, Swansea, Weston and York, was created by the Government of Ontario to support suburban growth. This new municipality could borrow money on its own for capital projects and it received taxes from all municipalities including Toronto, which meant that the Toronto tax base was now available to support the suburban growth. The new regional government built highways, water systems and public transit, while the thirteen townships, villages, towns, and cities continued to provide some local services to their residents. To manage the yearly upkeep of the new infrastructure, the new regional government levied its own property tax, collected by the local municipalities.
