Tornado Safety in Canada: What to Do Before, During, and After

Canada's Tornado Risk

Canada is second only to the United States in annual tornado frequency, experiencing an average of 62 tornadoes per year — though estimates from Environment Canada suggest the actual number may be higher due to many tornadoes occurring in unpopulated areas. "Tornado Alley" in Canada runs through southern Alberta, Saskatchewan, Manitoba, and southwestern Ontario.

Tornado Watch vs. Tornado Warning

Understanding the difference between a tornado watch and tornado warning can save your life. A Tornado Watch means conditions are favourable for tornado development — be alert and have a plan ready. A Tornado Warning means a tornado has been spotted or detected on radar — take shelter immediately.

Where to Shelter

The safest place during a tornado is an underground shelter or basement. If no basement is available, go to the lowest floor of the building, to an interior room away from windows (bathroom, closet, or hallway). Cover yourself with a mattress or heavy blankets to protect from debris.

If You Are Outdoors

If caught outside with no shelter available, lie flat in a low-lying area such as a ditch and cover your head with your hands. Do not shelter under highway overpasses — wind speeds are actually higher there. Never try to outrun a tornado in your vehicle.

Mobile Homes Are Not Safe

Mobile homes and manufactured homes provide almost no protection from tornadoes. If you live in a mobile home, identify the nearest substantial shelter ahead of time and go there when a tornado warning is issued — even if the tornado seems far away.

After the Tornado

Stay away from damaged areas. Watch for downed power lines, broken gas lines, and structurally damaged buildings. Do not enter any building until it has been declared safe. Document damage for insurance claims before cleaning up.
