History of Toronto
In 1998, the six municipalities comprising Metropolitan Toronto – East York, Etobicoke, North York, Scarborough, York, and the old City of Toronto – and its regional government were amalgamated into a single City of Toronto (colloquially dubbed the "megacity") by an act of the Government of Ontario. This was despite a municipal referendum in 1997 that was overwhelmingly against amalgamation. Subsequently, Mel Lastman defeated Barbara Hall to become the first elected mayor of the megacity.
Weston, Toronto
In 1967, it became part of the Borough (later City) of York. In 1998, York was in turn amalgamated with the five other members of Metropolitan Toronto, (Toronto, Etobicoke, North York, East York, and Scarborough) in the new "megacity" of Toronto. Vocal lobbying at the time allowed Weston to retain many street names which are exact duplicates of downtown streets, including Church Street, King Street and John Street.
