The west leg of the Toronto Transit Commission's Line 1 is set to grow with the addition of six new subway stations in northwestern Toronto and southern Vaughan, as work continues on the Toronto York Spadina Subway Extension (TYSSE). New photos submitted to the UrbanToronto Forum are giving us an updated view of the line's above-grade progress, and today we will cover the new stations' progression, starting from Downsview Park Station in the south, up to the new terminal at Vaughan Metropolitan Centre Station north of Toronto's city limits.

Downsview Park Station

Northwest of the current terminus at Downsview Station—to be renamed Sheppard West Station prior to the extension's opening—the above grade structure for Downsview Park Station is structurally complete, and is now being sealed off as cladding is applied. Hints of a green roof are also now visible above the station building. Designed by Aedas with project managers AECOM and design engineers Parsons Brinckerhoff, Downsview Park Station will connect the subway line with a new station on the Barrie GO line.

Finch West Station

Finch West Station is now taking shape just north of Finch on Keele Street. While not as far along as some of the other stations being built on the extension, above-grade construction has begun on Finch West Station's future bus terminal. The station will be clad in bird-friendly glazing, framed in uncoloured anodized aluminum, as well as a parapet wall and upper façade made up of black-and-white patterned fibrous composite cement panels. The station was designed by maverick "starchitect" Will Alsop of aLL Design, in partnership with engineers and architects of record IBI Group Architects.

York University Station

A recent UrbanToronto update about York University Station covered the 2,700 cubic metre concrete pour undertaken in September which formed the roof of the new station. Designed by Foster + Partners along with Arup Canada, a unique saddle-shaped above-grade structure will soon mark the entrance to York University's central rapid transit link.

Pioneer Village Station

Further north, the extension will bring a subway station to Steeles Avenue, between Jane and Keele Streets. As is the case with Finch West Station to the south, Pioneer Village Station features a design by Will Alsop, with engineers and architects of record IBI Group Architects. The station's multiple above-grade structures are in varying stages of completion, with the TTC substation building currently the furthest along, visible below, clad in Corten steel and vibrant red porcelain-coated panels. Also visible in the image below, the steel skeleton has taken shape for the station's north entrance.

The south entrance is a few steps ahead of the north entrance, with insulation installed in advance of exterior cladding, depicted in renderings as looking very similar to the two-toned pattern on the nearby substation building.

Below, a new TTC bus terminal can be seen taking shape as part of the station.

Highway 407 Station

While Pioneer Village Station will straddle the Toronto-Vaughan border, nearby Highway 407 Station is set to become the first TTC subway stop located entirely beyond Toronto's city boundaries. Located on the west side of Jane Street just south of Highway 407, the station is the result of a collaboration between lead designers Aedas, prime consultants AECOM, and engineers Parsons Brinckerhoff.

The station's above-grade superstructure is now largely in place, and other major design elements are now taking shape, including the elliptical light well that will allow natural light to penetrate deep into the station via a large enamel-painted glass window.

Vaughan Centre Station

Line 1's new northwestern terminus, soon to become the furthest north rapid transit stop on the TTC, the above-grade structure of Vaughan Centre Station is now taking shape near Highway 7 and Jane Street in Vaughan. Designed by Grimshaw Architects with engineers Arup Canada, the steel skeleton of the station's elliptical entrance stands in stark contrast with the unapologetic suburban nature of the surrounding buildings, though the area has begun its transformation into Vaughan's new Central Business District.

We will return with additional updates as work continues on the subway extension.
