Blair is a station on Ottawa's bus transitway and O-Train systems located at Blair Road and Regional Road 174. It is a major transfer point for commuters within urban Gloucester and Orléans.

This station is adjacent to the Gloucester Centre shopping complex, and nearby the Scotiabank Theatre Ottawa mega-movie theatre, a small bank, and other major retail stores. Shoppers City East located across Blair Road contains also several other major stores such as Canadian Tire. Headquarters of the Canadian Security Intelligence Service is located within a close proximity of the station. A long pedestrian overpass for the Queensway provides access to office complexes, a small park and ride parking lot, and the Pineview residential area.

Prior to the construction of the Confederation Line, this was the last station in the grade separated eastern leg of the transitway; after this point, buses used exclusive shoulder lanes on the Queensway beyond this point towards Orleans.

The main Transitway platforms closed down prior to Confederation Line construction as of 28 June 2015. The platforms reopened on September 14, 2019, when Confederation Line service began.

Blair station is the eastern terminus of the Confederation Line of the O-Train. It is an elevated island platform station, with both platform faces being used by terminating and departing trains. This will change when service is extended towards Trim in 2025.

The overpass of the previous Transitway station, located above the platforms at the concourse level of the station, was retained as part of the new O-Train station.

The station offers transfer to Transitway buses within the fare-paid zone—i.e. without needing to present proof of payment to transfer between buses and the station. The bus terminal is located on the ground level of the station. There are many heated shelters along the terminal with bus times for routes which serve each lettered platform.

The station's artwork, entitled Lightscape, is by cj fleury and Catherine Widgery. It is a series of suspended installations featuring brightly coloured elements that catch the light.
