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.
York, Upper Canada
After the war was over, the town continued to grow, expanding to the west, leaving the original town site, a less desirable location, somewhat undeveloped. A new parliament building was erected, near the original location, but this burned down and a new building was built in the new lands to the west. A permanent fort, Fort York, was built on the site of the garrison. Dundas Street was built to connect York to towns to the west. In the 1820s, the town experienced a surge of immigrants, expanding from 1,000 residents to over 9,000 by the time the town was incorporated as the City of Toronto in 1834. During its existence, the town did not have its own government; it was governed by the province of Upper Canada, with a mix of elected officials and an aristocracy known as the Family Compact controlling the government. By 1830, this led to an ongoing political conflict, which would later lead to the 1837 Upper Canada Rebellion.
When Europeans first arrived at the site of York, the vicinity was inhabited by the Iroquoian Seneca tribe (from the Five Nations Iroquois of New York State), who by then had displaced the Wyandot (Huron) tribes that had occupied the region for centuries before c. 1600. By 1701, the Iroquoian villages that had been established along the north shore of Lake Ontario during the sixteenth century had been abandoned. The Algonkian Mississaugas then moved into the York region, created alliances with the former Iroquoian residents, and established their own settlements; one near the former Seneca village of Teiaiagon on the Humber River.
