  • Stay informed of the situation (follow the Facebook or Twitter accounts of the City of Montreal and your city / borough)
  • Follow emergency workers' directions.
  • Leave your home if water levels become too high or if the authorities ask you to do so. Notify the city authorities where they can reach you if you do not go to a local emergency shelter.
  • Bring your survival kit, warm clothing, rain gear and identification for all occupants of your home.
  • Listen to the radio for the latest news.
  • Avoid moving vehicles in flooded areas.

  • Install a sump-type submersible pump (or make sure yours is working properly) as well as a backflow preventer in the basement.

  • Wait at least 10 days before consuming well water.
