OC Transpo
The Ottawa-Carleton Regional Transit Commission, doing business as OC Transpo is the primary public transport agency for the city of Ottawa, Ontario, Canada, operating bus rapid transit, light rail, conventional bus routes, and door-to-door paratransit in the nation's capital region.
OC Transpo was established in 1948 as the Ottawa Transportation Commission, and currently operates three urban rail lines, 11 bus rapid transit (BRT) lines, and 170 regular bus routes. OC Transpo serves 25 light rail (O-Train) stations, and 43 BRT (Transitway) stations. OC Transpo achieved a total ridership of 68 million in 2024.
Ottawa was notable for its Transitway system, a network of grade separated busways linking outer suburbs to the downtown core which originally opened with five stations in 1983, and continued substantial expansion into the late 2000s. Much of the Transitway infrastructure has been, and is currently being, converted to light rail since the opening of the Confederation Line (Line 1) in 2019.
Some OC Transpo routes also serve Gatineau in Quebec during peak periods. In addition, many Société de transport de l'Outaouais routes serving Gatineau also operate into downtown Ottawa.
Ottawa's transportation system is built around the rapid transit spines of the O-Train and Transitway networks. This rapid transit system is fed, and augmented by, frequent, express, and local bus routes.
The rapid transit network is primarily oriented around downtown and the nearby government offices therein, whereas the non-rapid network of frequent routes provide orbital coverage in the suburbs. The majority of Ottawa's busiest routes are orbital routes, including frequent routes 88, 6, and 7, despite not being rapid transit. Express routes parallel rapid corridors with limited stops during peak periods, while local routes are comparatively infrequent with closely spaced stops. Six rapid bus routes (57, 61, 75, 39, 45, and 97) have 24 hour service.
O-Train Line 1 forms the core of the network, accounting for a quarter of all transit trips in the city in 2023. It has three major Transitway interchanges, one O-Train Line 2 interchange, and one intercity Via rail station across its length. It is a 100% low floor, electric light rail line, and it is notable for being fully grade separated its entire length, which is uncommon for light rail services. The ongoing Stage 2 O-Train expansion will replace portions of the existing Transitway bus rapid transit network with extensions of the Line 1 and a new Line 3, which will interline Line 1 and add additional service to the west end of Ottawa.
O-Train Line 2 is one of the three primary north–south rapid transit corridors in the city, and duplicates the southeastern Transitway for part of its length. The primary trip generator on the line is Carleton University, and the line interchanges with Line 1 at Bayview, O-Train Line 4 (the Airport Link) at South Keys, and the southwestern Transitway rapid route 74 at Limebank station. Line 2 was closed for Stage 2 expansion on May 3, 2020, re-opening alongside the Line 4 on 6 January 2025. It was originally constructed as a low cost ($21 million) rail pilot project, using a disused mainline freight line. It operates diesel trains on single and double track at a frequency of every 12 minutes.
