History of Toronto
In 1998, the six municipalities comprising Metropolitan Toronto – East York, Etobicoke, North York, Scarborough, York, and the old City of Toronto – and its regional government were amalgamated into a single City of Toronto (colloquially dubbed the "megacity") by an act of the Government of Ontario. This was despite a municipal referendum in 1997 that was overwhelmingly against amalgamation. Subsequently, Mel Lastman defeated Barbara Hall to become the first elected mayor of the megacity.
York, Upper Canada
All land south of Dundas Street was reserved for expansion of the Town or Fort by the government as 'the Commons'. North of Dundas Street was the "Liberties", the eventual rural Township of York. It was divided into large 'park lots' where the city's moneyed elite built their estates, such as 'the Grange' and 'Moss park.' With time, some of these estate lots were subdivided, like the Macaulay family estate between Yonge St and Osgoode Hall (now Toronto City Hall), which became a working-class neighbourhood known as Macaulaytown. The original townsite area is today known as the "Old Town".
