I invite everyone to show solidarity with our more vulnerable citizens and I would like to thank our employees for their exceptional mobilization”, declared the mayor of Montréal, Valérie Plante. 

“Our teams are on the ground and closely monitoring the situation in order to adapt their actions according to the needs of the population. Today, we are activating our emergency measures coordination center to be able to deploy all necessary responses according to the latest developments”, added the director of the Service de sécurité incendie de Montréal, Bruno Lachance, who is also civil protection coordinator for the agglomeration de Montréal.
