Warning siren testing on Thursday, September 12

On Thursday, September 12, 2019, from 5:30 pm to 7:30 pm, there will be a siren test of at least three minutes at many factories across the island of Montreal, including the Parmalat factory on Saint-Jacques St., which is south of Côte Saint-Luc. Since sound waves are influenced by weather conditions, it is possible that people in Côte Saint-Luc (particularly the southern areas) may hear the siren. In the event of an actual emergency at the factory, the siren would warn people who are outdoors that they must seek shelter. Persons who are indoors will be alerted by radio and television.


The Agglomeration of Montreal, in collaboration with factories that use hazardous materials, is working to set an effective warning procedure to reduce the risks associated with a major industrial accident. The Centre de sécurité civile of Montréal, in collaboration with participating factories, has prepared a drill to test its warning sirens.

This drill aims to make sure that all sirens are working correctly and assess the state of preparedness of all emergency first responders. You can read this pamphlet (PDF) to understand what actions to take in the event of a major industrial accident and when you hear a warning siren.
