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.
City of Toronto Act
The Incorporation of the City of Toronto on March 6, 1834, was a legislative act creating the City of Toronto from the unincorporated town of York. This allowed for the creation of the local government or city council. The act was transferred onto the succeeding governments of Ontario in 1840 and 1867. The incorporation remained in effect throughout Toronto's mergers with other cities and towns within southern York County until the creation of Metropolitan Toronto in 1954.
