Construction Update: Downsview Park Station

The new Downsview Park Station will be the first stop on the Toronto-York Spadina Subway Extension (TYSSE). Centred under the GO Rail line, south of Sheppard Avenue West, this combined station will provide service to both the Barrie GO line and the TTC subway line. The Parc Downsview Park lands surrounding the two station entrances are designated for future development. This station will provide access to the park and will support future development within the station neighbourhood.

Construction progress

Building of the station began in Spring 2011. One of the unique aspects of this station is that the GO Rail line sits on top of the station box and runs between the two station entrance structures. The GO Rail line had to be moved temporarily to allow the station box to be constructed with the supports for the rail line. The rail line was moved back to its permanent location in December 2012.

While most of the work on the underground portion of the station structure is complete, the above-ground architecture is now beginning to take shape. All of the concrete work for the station box is finished up to ground-level, including the station platforms, and the concourse level and ground level floor slabs. Backfilling has started over some areas of the station. Installation of mechanical and electrical systems is continuing at the platform and concourse levels. Track installation through the station started in the fall of 2013.

The entrance structures are being built using steel frame construction and glazed curtain walls. The photos below show the west station entrance under construction, which is starting to resemble the artistic renderings of the structure.

The entrance structures feature a large open stairwell on the ground floor, with escalators and stairs to the concourse and platform levels. These are surrounded on three sides with glazed windows allowing daylight to reach track level. (photo below)

Sustainable design

While all six new TYSSE stations are designed to meet Toronto Green Standards, this station features a green roof on each entrance structure. Once the buildings are complete, special foliage will be planted, supported by an irrigation system. The green roof will cover 75 per cent (260 square metres) of the roof surface.

Subway service on the TYSSE is expected to begin in fall 2016.

The TYSSE project is an 8.6-kilometre extension of the Toronto Transit Commission’s Yonge-University-Spadina subway line from its present terminus at Downsview Station (to be renamed Sheppard West Station when the extension is complete) to the Vaughan Metropolitan Centre at Highway 7. It will have six new stations. The expansion of the subway will bring the line into The Regional Municipality of York.

The Toronto-York Spadina Subway Extension project is jointly funded by the Government of Canada, the Province of Ontario, the City of Toronto and The Regional Municipality of York.

In the next issue...

The next issue of Project News will feature Vaughan Metropolitan Centre Station, the last stop on the future extension.
