Do you live in a part of the town that’s at risk? The Ville de Mont-Tremblant asks you to take all possible steps to protect your family, your goods and your residence. This is primarily your responsibility, not that of emergency services.


Every year, some residents of the Ville de Mont-Tremblant have to prepare for the risk of flooding because their home is located on a flood plain. What follows is information to ensure appropriate preparation for possible flooding.

Bags and sand

The City offers bags that residents can fill with sand to protect their homes. Sand and bags will be available at the following locations (bring a shovel):

  • 60, chemin de Brébeuf (municipal garage) - Monday to Friday from 8:30 a‧m. to 12 p‧m. and from 1 p‧m. to 4:30 p‧m.
  • 109, chemin de la Sablière - Available at all times

The City reserves the right to provide sand and bags at other locations. If this is the case, you will be informed via our various digital platforms.


The Ville de Mont-Tremblant will keep a close eye on the flood situation. As soon as the level of the Diable River shows early signs of flood risk, the Ville will take readings of the river level in three places. The Ville website and Facebook page will be updated daily to indicate the flood risk.
