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

The Transitway is a bus rapid transit (BRT) network operated by OC Transpo in Ottawa, Ontario, Canada. It comprises a series of bus-only roadways and reserved lanes on city streets and highways. The dedicated busways ensure that buses and emergency vehicles on the Transitway rarely intersect directly with the regular traffic, and make it possible for them to continue at full speed even during rush hour. OC Transpo operates a network of rapid routes which use the Transitway to connect communities with the O-Train light rail system. Additional bus routes also use segments of the Transitway.
