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.
Areas of the City of York
York is an ancient English borough, and was one of the boroughs reformed by the Municipal Corporations Act 1835 to form a municipal borough. It gained the status of a county borough in 1889, under the Local Government Act 1888, and existed so until 1974, when, under the Local Government Act 1972, it became a non-metropolitan district in the county of North Yorkshire.
