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, Toronto
Humewood–Cedarvale was developed in the 1910s to attract development in the growing township. Oakwood–Vaughan was also developed during this time. In the 1920s, the character of the township changed, with its southern reaches abutting the city of Toronto taking on a more urban character, compared with the very rural character of the north. The decision was made to split the township in two, with the northern, rural portion becoming North York. The remaining, two pockets of unincorporated urban development at the north end of the city, were split by the village of North Toronto, which was by then a part of the City of Toronto. Within years, the Province of Ontario saw that this arrangement of having an exclave was impractical, and further subdivided York, creating the township of East York out of the eastern pocket. The Township of York contracted streetcar and bus services from the Toronto Transportation Commission (later became Toronto Transit Commission in 1954), but remained independent from Toronto. During this time, American novelist Ernest Hemingway resided in the Humewood–Cedarvale community, writing for the "Toronto Star".
