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.
The Annex
European settlement of this area began in the 1790s when surveyors laid out York Township. The area east of Brunswick Avenue became part of the village of Yorkville, while the region west of Brunswick was part of Seaton Village. In 1883, Yorkville agreed to annexation with the City of Toronto. In 1886, Simeon Janes, a developer, created a subdivision which he called the Toronto Annex. The Annex area became part of Toronto in 1887 and Seaton Village joined Toronto in 1888.
