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.
Old Toronto
The former town of York was incorporated on March 6, 1834, reverting to the name Toronto to distinguish it from New York City, as well as about a dozen other localities named "York" in the province (including the county in which Toronto was situated), and to dissociate itself from the negative connotation of "dirty Little York", a common nickname for the town by its residents. The population was recorded in June 1834 at 9,252.
