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.
Discovery District
The situation of these lots just north of the town meant that this land was in high demand as the city outgrew its original boundaries south of Lot (Queen). As most Toronto streets started at Lot (Queen), the 'park lots' commanded impressive views into the town and many of the buildings that were built as the 'park lots' were subdivided by their owner, were impressive institutions such as Osgoode Hall (Upper Canada's Law Courts) still standing, built at the top of York Street by 1832 just two years before the Town of York became a City with the name Toronto. By the time Toronto became a city in 1834, the area south of Lot St (Queen) from the Garrison Creek to the Don River had all been subdivided and the four 'park lots' north of Lot St (Queen) were subdivided by their owners with the eastern lot (Macaulay's estate) becoming the first residential district north of Queen, the western lot (Powell's estate) becoming the 'University Park', gated parkland intended to become Toronto's University and the area between on the north side of Lot St (Queen) attracting various institutions and businesses.
