Patrouille urbaine team members are available at all times to help residents find solutions to various issues. Though they may not be able to respond to every situation, they are in direct contact with various stakeholders who can (SPVM, SIM, foremen and women, etc.)

Patrouille urbaine team members are on the ground at all times, covering Saint-Laurent as a whole and thus playing a preventive role in the community.

In the event of a disaster, emergency service teams may call on the Patrouille urbaine to assist them. However, inspectors are not in a position to intervene directly or provide first aid. It is therefore important to always call emergency services before the Patrouille urbaine in such situations.
