Mount Dennis is an intermodal transit terminal in Toronto, Ontario, Canada, consisting of a rapid transit station on Line 5 Eglinton of the Toronto subway, a commuter rail station on GO Transit's Kitchener line, and an airport rail link station on the Union Pearson Express (UP Express). Located on Eglinton Avenue between the intersections of Weston Road and Black Creek Drive, it is the western terminus of Line 5 Eglinton. The station is a designated Metrolinx mobility hub and opened on November 16, 2025, for GO Transit, Toronto Transit Commission bus, and UP Express services, and February 8, 2026, for Line 5 service.
The station is named after the Mount Dennis neighbourhood where it is located and its signage bears the subtitle Weston Road on the Line 5 platform. It is situated on the lands formerly known as Kodak Heights, which was a camera manufacturing facility operated by the Eastman Kodak Company from 1918 until 2006. The station uses Kodak Building 9, a recreational heritage building and local landmark, as a station entrance.
Mount Dennis was originally conceived as York Centre stationnamed after the City of York, a municipality within the former Metropolitan Toronto before it was amalgamated into the present Torontowhich was planned to be the western terminus of an earlier proposed Eglinton West subway line. This was one of the three proposed subway lines in the Network 2011 plan created in 1985 by the Toronto Transit Commission (TTC). Construction started in 1994 but was subsequently halted when the project was shelved in 1995 following the election of a Progressive Conservative government led by Mike Harris. That station was planned to be located at Black Creek Drive on the south side of Eglinton Avenue as opposed to the farther-west north side location of Mount Dennis and would also have featured a connection to a new station on the Kitchener GO train line.
A draft prepared on April 10, 2013, established four designs for the station. In all the designs, the underground Line 5 Eglinton platform was long, enough for a four-car trainset. Two designs placed the bus platform on the north side of Eglinton, accessed through a pedestrian tunnel. In two designs other than the final product, the bus platforms were on the south side of Eglinton, accessed through a pedestrian tunnel.
By early 2016, the finalized design placed the bus loop on the north side of the station, accessed by a relocated Photography Drive bridge that crosses Eglinton further to the east than the old bridge. This roadway would pass east of the renovated Kodak building, which would form the station's third entrance. In February 2016, the original Photography Drive bridge over Eglinton Avenue was demolished to make way for construction on the Mount Dennis station site. In August of that year, the former Kodak building was temporarily moved to facilitate construction. On November 13, 2017, the building was moved back to sit on a newly built foundation. The community wanted this landmark preserved; thus, it became an integral part of the new station.
By mid-2019, track had been laid from the Line 5 station eastwards beyond the junction with the Eglinton Maintenance and Storage Facility and escalators and wall tiles were being installed; graffiti had been removed from the Kodak building and restoration work to its interior was in progress. By the fourth quarter of 2020, light rail vehicles were making test runs between Mount Dennis and stations.
On October 23, 2025, the province announced that the GO and UP Express platforms of the station would be opening on November 16, 2025, no matter the status of Line 5. Line 5 service to the station began with its opening on February 8, 2026.
In addition to being a landmark and of heritage interest, the former Kodak building is a focal point for riders using the mobility hub, as many of the mobility hub's features are linked to this building. It has a waiting area and public washrooms, and retail spaces on the main and basement levels. The upper floors of the building will be used for rented offices, to provide a space for community use, and will include an auditorium.
The station has three entrances:
The hub encompasses the following services:
The 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, including a window wall on the south side of the platform level, 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, Mount Dennis station features two artworks:
As Mount Dennis is a terminal station for Line 5, there is a diamond crossover to the east for reversing trains and tail tracks for overnight train storage to the west. Flanking the crossover is the lead-in trackage to the Eglinton Maintenance and Storage Facility to the north, which includes an additional trailing-point crossover to the east to access the eastbound mainline. The line then crosses Black Creek Drive and the eponymous Black Creek on an elevated guideway before descending into the western portal of the line's underground tunnels towards Keelesdale station.
