Amalgamation of Toronto
Forest Hill and Swansea were annexed by the City of Toronto, Leaside was merged with the township of East York to become the Borough of East York. Weston was combined with the Township of York to form the Borough of York. The Village of Long Branch and the towns of Mimico and New Toronto merged with the township of Etobicoke to form the Borough of Etobicoke. North York township was promoted to the Borough of North York. Scarborough was also transformed into a borough.Amalgamation occurred in 1998 when the regional municipality of Metropolitan Toronto and its six constituent municipalities – East York, Etobicoke, North York, Scarborough, York, and the City of Toronto (1834) were dissolved by an act of the Government of Ontario. A new single municipality called the City of Toronto (colloquially dubbed the "megacity") was formed, replacing all seven governments. The expanded city became the fifth most populous municipality in North America, behind Mexico City, New York City, Los Angeles and Chicago; it later surpassed Chicago in population.
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.
