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.
List of neighbourhoods in Toronto
Etobicoke is often divided into three zones: north, central, and south, roughly approximate to that of the federal and provincial ridings and city wards.
North York is located north of York, Old Toronto, and East York. It was a separate city until the 1998 amalgamation. North York is sometimes divided to two sections by Yonge Street: an east section and a west section.
Scarborough is on the east side of Victoria Park Avenue. It was a separate city until the 1998 amalgamation. West Rouge was transferred from Pickering to Scarborough in 1974 as part of the establishment of Durham Region. It was also the largest former municipality by area.
York is situated between Old Toronto and North York, west of Bathurst Street (aside from the neighbourhood of Tichester at the southeasternmost corner of the former city, which extends as far east as Walmer Road and includes much of St. Clair West station). Weston was independent of York until 1967. York was a separate city until the 1998 amalgamation. Since then, York is often administered with Etobicoke as a single community council within the amalgamated city of Toronto.
