Lila Presqu'île is also setting up a service on demand! 
Lila Presqu'île à la Demande is a service that complements the network's regular lines. It allows you to make journeys that are not covered by the regular lines so that everyone can get around in the Presqu'ile and the surrounding area.
You will be picked up at one of the 300 "Lila Presqu'ile" stops in the area and taken to another stop during the following times:
Monday to Saturday: 9.00am - 9.30am, 10.00am - 10.30pm, 11.30am - 12.00pm, 2.00pm - 2.30pm, 4.00pm - 4.30pm, 6.00pm - 6.30pm
Access to the service is possible for a one-way trip or a return trip.

Lila à la demande also offers its service to people with reduced mobility: Lila "door to door" with adapted vehicles and trained personnel. In this case, the vehicle picks you up at your home and takes you to the place of your choice. This door-to-door service is subject to medical advice. When you register for the service, you will be asked to provide proof.
