Located east of the intersection of Eglinton Avenue and Weston Road in the Mount Dennis neighbourhood in the district of York, the station will be the western terminus of the future Line 5 Eglinton as well as an intermediate station on the GO Transit Kitchener line and Union Pearson Express.

On the weekend of February 19 to 21, 2016, the Photography Drive bridge over Eglinton Avenue was demolished to make way for construction on the Mount Dennis station site.

[11] By August 2019, track had been extended from the station platform eastwards past the junction with the Eglinton Maintenance and Storage Facility, but overhead wire for pantographs had not yet been hung; escalators and wall tiles were being installed; graffiti had been removed from the Kodak building and restoration work to its interior was in progress.

[12] By the fourth quarter of 2020, light rail vehicles were making test runs between Mount Dennis and Keelesdale stations.

[1] The upper floors of the building will be used for rented offices, to provide a space for community use,[14] and will include an auditorium.
