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.
Government House (Ontario)
After the destruction of the Fort York house, York did not have another Government House until after the War of 1812. In 1815 the government purchased Elmsley House, a more commodious Georgian residence for its Lieutenant Governor. The next Government House was located in a wooded area to the west of the settled portion of the (then) Town of York, roughly midway on the block now occupied by Roy Thomson Hall and Metro Hall in downtown Toronto. Built in 1798, the residence had been the home of the Chief Justice and Speaker of the Legislative Assembly, John Elmsley, and it served as the colony's Government House from 1815 to 1841 (and intermittently from 1841 to 1858, during some of the times when Toronto served as the capital of the Province of Canada). For many years after its purchase by the government, the residence was still known by the name of its former owner, with the correspondence of the Lieutenant-Governor typically dated from "Elmsley House".
