The Toronto Transit Commission (TTC) has started work on the $2.6bn Toronto-York Spadina subway extension, which aims to cut travel times and ease traffic congestion on the route.
The 5.3-mile extension of the Yonge-University-Spadina subway line will run from the current terminus at Downsview Station in Toronto to the Vaughan Metropolitan Centre on Highway 7.
The project will include six new stations and provide rapid transit facilities to residents in the north-west part of Toronto, as well as creating a link between the Toronto and York regions.
The Canadian Government will provide about $700m to the project while Ontario, the city of Toronto and the Regional Municipality of York will contribute $870m, $526m and $352m respectively.
The project is expected to complete in late 2015.
