How can I reduce the risk of flooding in my home?

Floods are one of the most common hazards in Canada. Residents should be aware of the potential risks of flooding and be prepared to protect their home if flooding happens. You can follow these simple tips to protect your home and be prepared:

Inside your home

Prepare an emergency kit with essential items that you may require if you ever have to evacuate your home.

Talk to your insurance representative to make sure you have appropriate coverage.

Store your valuables upstairs or on high shelves.

Have a battery or crank radio available in case of power loss.

Check for and repair cracks, discolouration, dampness or swelling of basement floors and walls.

Have a wet/dry vacuum available.

Ensure that your sump pump is working properly and have a backup power supply in case of power outage.

Elevate the furnace, water heater and other large appliances and your electrical panel in your home.

If you home has a sanitary backwater valve, be sure to check and maintain it and do not use interior plumbing if it is in the closed position.


Outside your home

Move snow and ice at least two metres (six feet) away from your home's foundation.

Ensure that your yard is properly graded in order to direct water away from your home’s foundation and away from neighbouring properties.

Disconnect roof downspouts and divert runoff at least two metres (six feet) away from your home and away from sidewalks, driveways and neighbouring properties.

Clear ice, snow and litter away from city drains and catch basins, as long as it is safe to do so.

Report any blocked catchbasins, creeks or culverts to 3-1-1 (or 905-615-4311 if outside the city).

Stay away from creeks, rivers and crossings, as water levels can quickly rise.
