STO on demand



A complementary service for the Buckingham and Masson-Angers sectors

STO on demand, as the name suggests, is a personalized public transportation service offered on demand. The purpose of this service is to complement the conventional bus service in the Buckingham and Masson-Angers sectors in order to better meet your local transportation needs within those sectors. You asked us for more transportation options, so we came up with one just for you.

  • you have to book your ride;
  • your service area is limited to within those sectors, to and from an existing stop or other reference point;
  • door-to-door service will be offered to customers eligible to Paratransit service;
  • the service is flexible and adapted, designed to meet your transportation needs;
  • a practical way to get where you want to go, when you want, within those sectors, during standard service hours;
  • riders traveling in the same direction may share a vehicle; and
  • Service offered by Taxi Loyal.



On demand service coverage now includes the area along Route 148, east of boulevard de l'Aéroport.

Now that Route 97 runs along Autoroute 50, bus service along Route 148 is discontinued between boulevard de l'Aéroport and avenue des Laurentides.

Residents in this area can book an on demand ride to the Parc-o-bus Cheval-Blanc or the Parc-o-bus Georges/Route 148, where they can then transfer to the regular STO system.

On demand rides can also be booked to the Buckingham and Masson-Angers sectors.
