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.
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.
