Getting Around Ottawa: The O-Train and OC Transpo
OC Transpo runs public transit in Ottawa, and the system is built from two kinds of service: the O-Train, a network of numbered rail lines, and a bus network that feeds the rail lines and reaches the parts of the city they do not serve. The rail lines carry the heaviest volumes through the core; the buses do most of the reaching.
Because the network has been extended and reorganised in stages, and because fares and pass products are set by Council and revised, this guide concentrates on how the system is organised and how to use it, and points to OC Transpo for anything that changes.
The O-Train lines
The O-Train is organised as numbered lines. Line 1, the Confederation Line, is the light rail route through the downtown core, running between Tunney’s Pasture in the west and Blair in the east, and it connects to Line 2 at Bayview Station. Line 2 is a diesel light rail line running north to south between Limebank Station in the south and Bayview just west of downtown, connecting to Line 1 at Bayview and to Line 4 at South Keys Station. Line 4 links South Keys Station to the airport.
Because the network has been built in phases, the current lines, termini and interchanges are the ones to check on OC Transpo’s network map, rather than a description in an older article or a screenshot of a previous network.
How the bus network fits in
OC Transpo sorts bus routes into service types, and the type tells you what kind of trip the route is designed for. Knowing the category makes it much easier to compare options when a trip crosses the city.
- Frequent routes — high-frequency service along main roads, running seven days a week.
- Local routes — customised routing to destinations that are not on a frequent route, including limited variants that run only at certain times or on certain days.
- Connexion routes — peak-period connections between residential communities and the O-Train.
- Express routes — limited-stop, peak-period service linking Park and Ride lots, employment areas and Line 1 stations.
- Night routes — overnight, station-to-station bus service when the O-Train is closed for the day.
- Replacement bus services (R1, R2 and R4) — deployed on a rail line when it is not running during regular service hours.
Fares, passes and how to pay
The fare is the same across the OC Transpo network, including the O-Train, which removes the usual ambiguity about which service you are buying. Payment options include a Presto card, O-Payment by credit card, debit card or mobile wallet, and cash. A single-ride fare includes a transfer window that varies by time of day, and day, multi-day and monthly passes are available. With Presto, fare capping means a day of travel will not cost more than a day pass and a month will not cost more than a monthly pass.
Reduced fares exist for several groups, including seniors, youth and children, and eligibility-based products such as the EquiPass, Community Pass and Access pass. Where a discount applies, it has to be set on the card rather than being applied automatically at the reader.
Accessibility
OC Transpo publishes accessibility information separately for vehicles and for stations, covering features such as accessible boarding, priority and cooperative seating, spaces for wheelchairs and mobility devices, travel aids, support persons and service animals. There is also travel training for customers who want help learning a route, and information on rural transportation options.
Accessibility varies by station and stop, and the station-level pages hold the detail: what is step-free, where the lifts are, and how transfers between lines and buses work at that location. Treating a line as uniformly accessible is the mistake to avoid.
Para Transpo
Para Transpo is Ottawa’s parallel transit service for people who cannot use conventional buses and trains some or all of the time because of a disability. It is a shared-ride, book-in-advance service funded by the City of Ottawa and administered by OC Transpo, using minibuses and contracted taxis. It operates in the urban area, between urban and rural areas, and across the river to Gatineau.
Eligibility is assessed through an application rather than self-declared, and applicants are contacted once a decision has been reached. Registered customers receive a Para Transpo ID, can open a ParaPay account to pre-pay fares or use a Presto card, and can book, cancel or track trips through the My Para Transpo self-serve system or by phone. A taxi coupon programme provides discounted taxi travel as an alternative to Para Transpo.
Planning a trip, and the river boundary
OC Transpo’s Travel Planner is the authoritative planning tool, because it reflects current schedules, detours and seasonal service changes, and route schedules, station pages and service alerts fill in the rest. For a quick check on the street, stop numbers can be used for next-departure information by text, phone or the OC Transpo site.
One complication is specific to the capital region. Gatineau, directly across the Ottawa River, is served by a different transit agency, STO. A trip that crosses the river involves two operators, and fares, passes and transfer arrangements are set separately by each agency rather than being interchangeable.
- Plan with the Travel Planner and check alerts on the day you travel.
- Confirm whether a cross-river trip uses OC Transpo, STO or both.
- Do not assume a pass or a transfer carries between the two agencies.
