North York is located directly north of Old Toronto, between Etobicoke to the west and Scarborough to the east. As of the 2011 Census, it had a population of 655,913. It was first created as a township in 1922 out of the northern part of the former city of York, a municipality that was located along the western border of Old Toronto. Following its inclusion in Metropolitan Toronto in 1954, it was one of the fastest growing parts of the region due to its proximity to Old Toronto. It was declared a borough in 1967, and later became a city in 1979, attracting high-density residences, rapid transit, and a number of corporate headquarters in North York City Centre, its central business district.
It is one of the cities that in the 1997 City of Toronto Act became a part of the Toronto mega-city. It has a unique charm being its own brand of multiculuralism. It has become a city within a city.
