South Keys station is the southernmost station of the Southeast Transitway in Ottawa. The station is located in the South Keys neighbourhood, behind the south end of the South Keys Shopping Centre, and between Bank Street and the Airport Parkway. The Transitway station was opened for bus service on September 2, 1995. Previously, City Council approved the addition of an O-Train station at South Keys (instead of Lester) in conjunction of the expansion of the north–south light rail line. The project was cancelled on December 14, 2006. In 2024, an O-Train station will open next to the existing Transitway station, serving as the transfer point between the Trillium Line and the Airport Link.

O-Train station

In 2024, an additional island platform O-Train station will be opened on the west side of the Transitway station, accessible by elevator or stairs via the existing pedestrian walkway beneath the station. The South Keys O-Train station will serve as a transfer station between Line 2 and Line 4, (the "Airport Link"), and has been designed with a third pocket track to enable operations for cross platform transfers between the two lines. A Line 4 train will drop off its passengers on the northbound platform, then move to the pocket track to allow Line 2 trains to serve both north and southbound platforms. The Line 4 train then moves to the southbound platform to pick up Airport-bound passengers.
