Municipal government of Toronto
On January 1, 1967, several of the smaller municipalities were amalgamated with larger ones, reducing their number to six. Forest Hill and Swansea became part of Toronto; Long Branch, Mimico, and New Toronto joined Etobicoke; Weston merged with York; and Leaside amalgamated with East York. This arrangement lasted until 1998, when the regional level of government was abolished and Etobicoke, North York, East York, York, and Scarborough were amalgamated into Toronto the "megacity". Mel Lastman, the long-time mayor of North York before the amalgamation, was the first mayor (62nd overall) of the new "megacity" of Toronto, which is the successor of the previous City of Toronto.
York, Toronto
York Township was incorporated by Canada West in 1850 (Canada West later became Ontario in 1867, due to Confederation), bounded in the west by the Humber River, in the east by what would become Victoria Park Avenue, and in the north by what would become Steeles Avenue. Etobicoke Township and Scarborough Township were located west and east, respectively, while the townships of Vaughan and Markham bordered on the north.
