Preparing for a flood

Floods are the most costly natural disasters in Canada in terms of property damage. They can occur in any region, in the countryside or in cities. In the past, floods have affected hundreds of thousands of Canadians.

In the spring, the amount of additional precipitation and the timing and rate of the snowmelt both have a significant impact on the flood potential, making flooding an imminent threat.

Next to the spring thaw, heavy storm rainfall is the most common cause of flooding, especially when the ground is already saturated from previous storms.

Flash flooding – in which warning time is extremely limited – can be caused by violent storms, earthquakes or dams bursting. These phenomena all outline the importance of getting prepared before such a disaster occurs. Learn how to prepare yourself with these safety tips.

Reduce the likelihood of flood damage in your home

• Put weather protection sealant around basement windows and the base of ground-level doors.
• Install the drainage for downspouts a sufficient distance from your home to ensure that water moves away from the building.
• Consider installing a sump pump and zero reverse flow valves in basement floor drains.

If in immediate danger of flooding:

• Turn off basement furnaces and the outside gas valve.
• Properly safeguard electrical, natural gas or propane heating equipment.
• Shut off the electricity. If the area around the fuse box or circuit breaker is wet, stand on a dry board and shut off the power with a dry wooden stick.
• Try to move furniture, electrical appliances and other belongings to floors above ground level.
• Remove toxic substances such as pesticides and insecticides from the flood area to prevent pollution.
• Remove toilet bowls and plug basement sewer drains and toilet connections with a wooden stopper.
• Disconnect eavestroughs if they are connected to the house sewer.

During a flood

Keep your radio on to find out what areas are affected, as well as what roads are safe, where to go and what to do if the local emergency team asks you to leave your home. You'll want to have your emergency kit close at hand, in a portable container such as a duffel bag or suitcase with wheels.

Important: Avoid crossing a flooded area, either or on foot or in your car. The water may be deeper than it looks, and may be rising quickly.
