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.
East York
The borough of East York was established in 1967 through the amalgamation of the former township of East York and the former town of Leaside. Leaside was a planned industrial and residential community. East York has over the years been a residential enclave for senior citizens, as the original owners from the 1940s age and as younger families move out to suburbs to live in larger houses. East York had its own fire department with three stations, which are still in operation today under the combined Toronto Fire Services. Recently, rapid and accelerated gentrification has changed many neighbourhoods. Many one-story bungalows have added second floors, and many shops have been converted to more upscale shops. Canada's only borough, East York was semi-autonomous within the greater municipality of Metropolitan Toronto.
