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.
Municipal government of Toronto
Change to the legal structure came in 1954, with the creation of the Municipality of Metropolitan Toronto (known more popularly as "Metro") in 1954. This new regional government, which encompassed Toronto and the smaller communities of East York, Etobicoke, Forest Hill, Leaside, Long Branch, Mimico, New Toronto, North York, Scarborough, Swansea, Weston and York, was created by the Government of Ontario to support suburban growth. This new municipality could borrow money on its own for capital projects and it received taxes from all municipalities including Toronto, which meant that the Toronto tax base was now available to support the suburban growth. The new regional government built highways, water systems and public transit, while the thirteen townships, villages, towns, and cities continued to provide some local services to their residents. To manage the yearly upkeep of the new infrastructure, the new regional government levied its own property tax, collected by the local municipalities.
