Don Valley is an underground Toronto subway station on Line 5 Eglinton in Toronto, Ontario, Canada. It is located in the Flemingdon Park neighbourhood at the intersection of Don Mills Road and Eglinton Avenue.

On April 10, 2019, the Ontario government announced that Don Valley station, under its planned name Science Centre, would be the northern terminus for the proposed Ontario Line, construction of which began in March 2022.

Description

This station's main entrance is located at the southwest corner of the intersection with Don Mills Road. A secondary entrance is on the opposite northeast corner, with a new bus terminal stretching beyond that to Gervais Drive. The TTC bus terminal will have seven bus bays as well as on-street bus connections. An underground, accessible passage will link the bus terminal to the light rail transit concourse level, which will have retail spaces. The station will provide 30 outdoor and 30 indoor bicycle parking spaces.

The underground Don Valley station was built using cut-and-cover method. The station is between two surface sections of the line. To travel under Don Mills Road, the line dips underground, passes through the station under the middle of Eglinton Avenue and re-emerges to the surface at the other side. To the west of Don Valley station, there is a facing-point crossover just beyond the ramp descending to the station's west portal. To the east of the station, there is a double crossover on the ramp descending to the station's east portal.

Architecture and artwork

The Line 5 station was designed by Arcadis, following an architectural concept designed by architects gh3* from Toronto and Daoust Lestage Lizotte Stecker from Montreal. As with other stations on Line 5, architectural features include natural light from large windows and skylights, steel structures painted white, and orange accents (the colour of the line).

As part of a program to install artworks at major interchange stations along Line 5 Eglinton, Don Valley station features an artwork titled Total Lunar Eclipse by British-American artist Sarah Morris. The artwork is a mural consisting of porcelain tiles that were silkscreened by hand. According to the artist, the artwork is a "wall painting" that "invites reflection on concepts of light, scale and motion through space".

The station's main entrance has louvres in the glass panels above the doors. Metrolinx predicted that the louvres "will be a well-known and a distinctive part of the transit destination's look".

During the planning stages for Line 5 Eglinton, the station was given the working name Don Mills. In November 2015, a report to the TTC Board recommended giving a unique name to each station in the subway system (including Line 5 Eglinton). Thus, the station was named Science Centre to reflect its proximity to the Ontario Science Centre (similar to Museum station, which is adjacent to the Royal Ontario Museum) and to avoid confusion with the existing Don Mills station on Line 4 Sheppard.

In April 2023, the Ontario provincial government announced plans to move the Science Centre to Ontario Place (near the opposite terminus of the Ontario Line). In June 2024, the government announced that the Science Centre would close permanently following an engineering report that cited a significant risk of roof collapse.

On March 28, 2025, as a result of the closure, Metrolinx announced that the station would be renamed Don Valley to reflect the station's proximity to the Don Valley Parkway, the Don River, and the Don Valley itself. Other names considered for the station were Concorde, Industrial District, Olympia Square, Ferrand, and Don River.

Don Valley is one of the Line 5 stations that was reported to have most excited developers. On April 3, 2017, Urban Toronto reported that the City's planning department's initiative for the intersection had been named Don Mills Crossing, while it would be accompanied by a plan for nearby properties, in 2018.
