The primary entrance and an off-street bus loop are located at the northeast corner of Eglinton Avenue and Trethewey Drive. A secondary entrance is located on the northwest corner of Eglinton Avenue and Trethewey Drive adjacent to York Memorial Collegiate. A third entrance is located at the southeast corner of Eglinton Avenue and Keele Street. The primary entrance will be fully accessible and have a station plaza with a landscaped public space. The station will have four bus bays plus on-street connections for TTC buses. Noise attenuation walls will be placed between the bus bays and neighbouring houses. There will be outdoor parking for 60 bicycles.[3]
During the planning stages for Line 5 Eglinton, the station was given the working name "Keele", which is identical to the pre-existing Keele station on Line 2 Bloor–Danforth. On November 23, 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 LRT station was renamed "Keelesdale". Silverthorn was also considered.[4]
Before construction, land expropriations and demolitions were required. The primary entrance is at the site of former EMS Station 19 and a car wash.[5] The secondary entrance is at the site of a former Coffee Time outlet and its adjacent parking lot.[6]

TTC staff evaluated the initial report and the proposed names and provided feedback and recommendations. A primary TTC concern was to avoid replication and redundancy with existing TTC station names. The proposed names are unique and are not likely to be confused with existing station names.
