federal government, on former grounds of Canadian Forces Base Toronto. History York Centre was originally created in 1903 from parts of York East and York West ridings. It was created when the county of York (excluding the city of Toronto) was divided into three ridings: York Centre, York North and York South. The centre riding consisted of the townships of Etobicoke, Markham, Scarborough and Vaughan, and the villages of Markham, Richmond Hill, Weston and Woodbridge. The electoral district was abolished in 1914 when it was redistributed between York East, York South and York West. In 1952, York Centre was re-established with parts of Eglinton—Lawrence, Willowdale, York North and York West ridings. The new riding consisted initially of the part of the township of North York west of Yonge Street, the part of the township of Vaughan south of Highway Number 7, and the town of Woodbridge. In 1966, it was redefined to consist of the part of Metropolitan Toronto bounded on the north by the northern limit, and on the west, south and east by a line drawn from that borough limit south along Highway 400, east along Sheppard Avenue West, south along Jane Street, southeast along Exbury Road, east along Calvington Drive, south along Keele Street, east along Highway 401, south along the Canadian National Railway line, east along Lawrence Avenue West, north along the Spadina Expressway, northeast along Highway 401, north along Bathurst Street, east along Sheppard Avenue West, south along Easton Street, east along Cameron Avenue, and north along Yonge Street to the Metro Toronto limit. It is unclear why the name York Centre was retained as the district was now predominantly in the Borough of North York rather than in the Region of York. In 1976, it was redefined to consist of the part of the Borough of North York bounded on the north by the borough limit, and on the west, south and east by a line drawn from the borough limit south along Highway 400, east along Sheppard Avenue West, south along Keele Street, east along Highway 401, north along Bathurst Street, and northwest along the West Branch of the Don River to the borough limit. In 1987, it was redefined to consist of the part of the City of North York bounded on the north by the city limit, and on the east, south and west by a line drawn from the city
