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.
History of Toronto
In 1793, Lieutenant Governor John Graves Simcoe moved the capital of Upper Canada to Toronto, which he named York, not wanting an aboriginal name. Simcoe originally planned for York to be a city and military outpost and to set up a capital in the area of London, Ontario, but he abandoned the plan and York was named the permanent capital in 1796. The Mississaugas set up a settlement reserve in the area of Port Credit to the west of York and eventually moved further to the west.
