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.
New Toronto
In 1953 the Town of Mimico, Town of New Toronto, Village of Long Branch, Etobicoke Township, Village of Swansea, Village of Forest Hill, Village of Weston, Town of Leaside, East York Township, North York Townsip, York Township, Scarborough Township and City of Toronto joined together to create a new common level of government: Metropolitan Toronto (Metro). Each municipality retained its own town council and government, but several infrastructure departments were transferred to Metro. This lasted until 1967, when the number of municipalities in Metro was reduced.
