The By-law concerning the Service de sécurité incendie de Montréal dictates the SIM's responsibilities and gives the department the powers needed to assume its responsibilities in an optimal way.

The By-law concerning fire prevention updates the requirements and corrects the obsolescence of standards used in the field.

This by-law was established to ensure the safety of citizens in the agglomeration of Montréal, fewer and fewer of whom respond to fire alarms.
