Smoke alarms remain the most effective and least expensive way to save lives in the event of a fire, particularly at night.
The By-law concerning the Service de sécurité incendie de Montréal (RCG 12-003) was amended in June 2019. Now, all residential buildings in the Montréal agglomeration that were built before 1985 must be equipped with a smoke alarm powered by a non-removable lithium battery with a lifespan of 10 years. Buildings that were built after 1985 must be equipped with smoke alarms that are connected to an electrical system.
