Changements à la desserte au centre-ville d'Ottawa



We're sorry, this page is under construction. The complete information will be available soon.


The arrival of the Confederation Line will result in changes to the OC Transpo system as well as the STO system. Service to downtown Ottawa will eventually be modified to make connections between the two systems easier.

When the O Train Confederation Line begins operating, Albert and Slater will be reconfigured for the STO service, among other things.

We have determined that it is better for STO buses to avoid this area during the work so as not to impede construction and to optimize the efficiency of the bus service provided for our clientele.

Major changes to the STO system in downtown Ottawa will be made later in 2019, depending on the progress of the work.

If you use the STO system only

There are no route changes for the moment.

If you normally transfer to the OC Transpo system

The OC Transpo system will be modified when the Confederation Line begins operation (in early 2019).

Customer questions and comments

In June, we asked our rider panel members for their opinion on the new service to downtown Ottawa. Their comments have allowed us to understand your concerns. You will find answers to your questions below!

1-What measures will be taken to assist riders with the changes?

While many riders will be taken closer to their final destination, some will have the option to walk or to transfer, but to a high frequency service such as the O-Train or another STO bus route. Several weeks before the changes take effect, Plani-Bus will recommend the best options for your trips.
Furthermore, ample signage will also be provided to help you find your way to the light rail stations and STO stops. For instance, in the O-Train stations, screens will display the real time that STO buses will be passing at nearby stops. More details will be made available over the next few months.

2-Will STO riders be able to transfer to the O-Train?
Currently, STO transit passes and tickets entitle you to a valid transfer for STO and OC Transpo services. This will still be the case:

  • Riders using a pass on a smart card (monthly or annual pass, Cam-Puce pass or U-Pass) can travel on both systems without any restrictions.
  • E-passes valid for 1 or 3 days (Passe-temps and L'Escapade) must first be validated on an STO bus before they can be used without restrictions on both systems.
  • Riders using the e-wallet can travel on the OC Transpo system after validating their card on an STO bus, which entitles them to an e-transfer that is valid for two hours. However, the e-wallet is not accepted for starting a trip on the OC Transpo system.

3-Will buses be slowed by traffic congestion and traffic lights? Will they be able to make the turns?
We are currently working with our OC Transpo colleagues on the street configuration along the three routes that will be taken by STO buses. Some work has already started, and traffic studies have been completed. In light of the results, several measures will be implemented to make travel easier for the buses, such as changing the geometry and layout of streets, and synchronizing traffic lights. This will all be announced in the next few months.
Don't forget that the volume of OC Transpo buses will decrease considerably in downtown Ottawa once the Confederation Line begins operation.

4-Will there be more riders at the stops?
STO riders will be distributed among more stops, with 9 stops instead of the current 6. In addition, few stops will be shared by OC Transpo and STO buses, since OC Transpo's downtown service will be completely revised. The platforms will also be longer, making it easier to board.

5-Will the OC Transpo system be modified?
Yes, the OC Transpo bus system will be modified, in particular downtown. The details of the changes will be announced by OC Transpo in the next few months, and we will post the information at You can visit OC Transpo's “Ready for Rail” site to learn more.

6-Will the routes also be modified on the Quebec side?
No, there will be no route changes, except for some minor adjustments.

7-Will the frequency of STO buses be reduced?

No, the frequency will remain the same. As always, the service will be adapted based on demand by using articulated buses or adding trips when necessary.

8-Will fares increase?
The fare schedule is adjusted annually, but the new service to downtown Ottawa will not generate an additional fare increase.
