Transport Canada has commenced next stage of tunnelling work on the Toronto-York Spadina Subway Extension (TYSSE) project in Canada.
The scope of work in this phase of TYSSE project involves excavation of twin tunnels, which will link the site of the future Highway 407 Station to the Steeles West Station site. The tunnels will be bored using two tunnel boring machines, namely Yorkie and Torkie.
The TYSSE is a smart transportation project, which will improve air quality and offer long-term economic growth in the GTA. The project involves expanding the Toronto Transit Commission's (TTC) Yonge-University-Spadina subway line by 8.6km from its present terminus at Downsview Station to the Vaughan Metropolitan Centre at Highway 7.
The extended line will have six new subway stations, including one at York University and three new commuter parking lots. The subway expansion will bring the line into York Region and will provide an important transit connection into York Region and the Vaughan Metropolitan Centre and help create a seamless transit network across the Greater Toronto and Hamilton Area.
The project has received up to CAD697 million ($678.82 million) from the government of Canada, of which CAD622 million ($605.78 million) has been provided through its Building Canada Fund and the remaining CAD75 million ($73.04 million) under the Public Transit Capital Trust 2006. The project is scheduled for completion in late 2016.
The province of Ontario has provided CAD870 million ($847.31 million) through the Move Ontario Trust and the city of Toronto has allotted CAD526 million ($512.28 million) and The Regional Municipality of York is contributing CAD352 million ($342.82 million) for the TYSSE.
