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.

The 'New Town' grew slowly and it was not until the Town of York was incorporated as the City of Toronto in 1834 that the 'New Town' grid was extended from Peter Street to as far west as the Garrison Creek creating the 'New Town Extension' with its curved Niagara Street, later extended a block closer to the Garrison Creek with Walnut Street.
