How to protect your home in the event of a flood

Floodwater surrounds several single‑story homes, submerging yards and reflecting the buildings and trees.

Flooding can occur at different times of the year, particularly in the spring during snowmelt or following heavy rainfall.

Floods may be caused by:

  • Rising rivers and waterways
  • Ice accumulation or ice jams breaking up
  • Heavy rainfall
  • Sewer backups or insufficient drainage.

Even though certain preventive measures can reduce risks, it remains difficult to accurately predict the timing and severity of a flood.

Various monitoring and response measures are implemented during high risk periods, including water level monitoring, the deployment of emergency resources, and the issuance of pre alert or alert notices to the public.

Explore the steps you can take to prepare your home and reduce damage when flooding occurs

Exterior openings

Protect basement windows using securely fastened panels.

Floor drains

  • Ensure the backwater valve is functioning properly.
  • Close off the drain if no backflow valve is installed.

Electricity

  • Shut off the electrical power if water may reach electrical installations.
  • Never enter a flooded area if the power has not been turned off.

Heating systems and appliances

Consult your service provider to determine the appropriate precautions.

Furniture and personal belongings

Move furniture, appliances, and valuables to upper floors.

Hazardous products

Store toxic substances (oils, solvents, pesticides) in a safe location to prevent contamination.
