1. STO — your local network
The STO, or Société de transport de l'Outaouais, runs the buses in Gatineau.
The network covers the five sectors: Aylmer, Hull, Gatineau, Buckingham and Masson-Angers. Several Rapibus lines cross the city quickly on a dedicated lane.
2. The Ottawa connection
Many Gatineau residents work in Ottawa. Several STO lines cross the bridges to Ottawa, and several OC Transpo lines come into Hull.
If you commute daily between Gatineau and Ottawa, one STO monthly pass is enough: according to the STO, it is accepted on OC Transpo buses and the O-Train at no extra charge. It is loaded on the Multi card, the STO's reloadable fare card.
3. The Rapibus
The Rapibus is the STO's bus rapid transit system, with its own dedicated lane separated from car traffic.
It connects east Gatineau to downtown Hull, then to the Ottawa bridges. It's the fastest way to cross the city.
4. Fares and cards
STO offers several fare options: e-wallet trips, 1-, 3- or 7-day passes and the monthly pass — all loaded on the Multi card. You can also pay cash, exact amount only. The monthly pass and the day passes are also accepted on the OC Transpo network.
5. Pass options at a glance
STO passes vary based on your travel frequency. Here are the main options and typical use for each.
Specific fares change annually — check sto.ca before choosing a pass. For a one-off trip to Ottawa, pay your fare on an STO bus: according to the STO's Travelling with OC Transpo page, a trip paid with the Multi card e-wallet gives you a 2-hour transfer, at no extra charge, on OC Transpo buses and the O-Train. The e-wallet cannot be used to start a trip on OC Transpo, however. Note that children aged 12 and under ride free with a paying adult and that STO offers reduced rates for full-time students.
| Pass | Network covered | Who for |
|---|---|---|
| STO trip on the e-wallet (Multi card) | STO, then a 2-hour transfer on OC Transpo and the O-Train | Occasional rider, including a one-off trip to Ottawa |
| STO 1-, 3- or 7-day pass | STO, OC Transpo and the O-Train while valid | Exploration or one-off outing |
| STO monthly pass | STO, OC Transpo and the O-Train, first to last day of the month | Commuter within Gatineau or to Ottawa |
| Student or senior reduced fare | Varies by pass | Student or 65+ |
6. Understanding the bridges between Gatineau and Ottawa
Five bridges connect Gatineau to Ottawa, which entirely shapes commuter life. According to the STO, its buses to downtown Ottawa use the Portage bridge; heading to Ottawa, some lines take the Macdonald-Cartier bridge instead.
At rush hour, the bridges become major bottlenecks — exactly where the Rapibus and reserved lanes outpace cars.
7. Practical tips for new riders
A few useful habits from your first weeks in Gatineau:
- Download the Transit app, which the STO recommends — it shows your buses in real time and flags delays.
- Learn the sector names — a stop in Aylmer is nowhere near a stop in Buckingham.
- In winter, build a few minutes of buffer — buses can run late on icy roads.
- Check both schedules if you cross to Ottawa — STO and OC Transpo don't auto-sync.
8. Frequently asked questions
The most common questions from new Gatineau residents about STO and OC Transpo: Multi card, children's fares, delay handling and the car decision.
How does the Multi card work with OC Transpo?
The Multi card is the STO's reloadable fare card: it isn't a pass in itself, it carries your passes. According to the STO, the monthly pass loaded on it gives unlimited trips from the first to the last day of the month and is valid on the OC Transpo network, buses and O-Train included.
You reload the card online (48 hours before your next trip), at an STO service point or at a point of sale; prices are on the STO's Regular fares page. If you pay per trip with the e-wallet, the first validation must be on an STO bus and gives you a 2-hour transfer on OC Transpo.
Do my children need to pay to ride the bus with me?
Children aged 12 and under accompanied by a person who pays the fare ride free on the STO network.
Older children and teenagers fall under reduced student rates on proof. If your child rides alone to school, look into the STO student passes, often the best option for the school year. The grid changes from year to year, so check sto.ca at the start of each school year.
What should I do if my Rapibus is delayed or cancelled?
The Transit app, recommended by the STO, is the fastest way to know what's going on — it shows real-time positions and posts service alerts.
If a Rapibus is severely delayed, watch the next bus on the same line: frequencies are usually high enough that the next one is only a few minutes away. In a major outage (heavy snow, accident on the reserved lane), STO announces it through its System-Info alerts and on its X account @STO_direct (formerly Twitter). As a last resort, regular STO lines sharing part of the route can serve as plan B.
Is it worth keeping a car if I work in Ottawa?
It depends on your schedule and where you live. At rush hour, the Rapibus combined with OC Transpo is often faster than the car — the bridges to Ottawa form major bottlenecks.
A monthly STO pass, valid on OC Transpo too, also costs much less than a parking spot in downtown Ottawa, where space is limited and expensive. On the other hand, if you have to pick up children, do groceries far from STO lines, or work outside standard hours, the car keeps its usefulness. Many Gatineau families end up with a single car instead of two by relying on the bus daily.

Author's Note: If you work in Ottawa, one STO monthly pass is enough: it's also valid on OC Transpo. The Rapibus is your best friend: dedicated lane, high frequency, far faster than driving at rush hour.
