Transit is useful for airport, rail-station, downtown and neighbourhood travel, but visitors should check the current route rather than relying on an old map.
Current fare context
As of July 2026, OC Transpo lists adult single-ride payment at $4.10 by Presto or O-Payment and $4.15 cash, with a transfer period and daily capping available under specific payment rules. Fares can change, so verify before publishing or travelling.
Pay consistently
When using contactless payment, use the same physical card or the same device throughout transfers and daily capping. Switching between a card and its mobile-wallet version can be treated as separate payment methods.
Airport connection
O-Train Line 4 connects Ottawa International Airport to South Keys, where passengers transfer for the rest of the network. Check service advisories and late-night schedules.
Visitor habits
- Screenshot the route and platform.
- Allow transfer time.
- Check accessibility status for elevators.
- Know whether the return trip runs after an evening event.
