Preparing Canadians for severe weather, thunderstorms, and tornadoes
MISSISSAUGA, ON, July 7, 2026 – As Canada enters the heart of summer storm season, new analysis from First Onsite Property Restoration’s annual Weather and Property Survey finds that concerns about flooding, severe storms, tornadoes, and climate-related weather remain high across the country.
Environment Canada’s summer outlook points to above-normal temperatures across much of the country, with heat and humidity expected to increase the risk of severe thunderstorms. These conditions can bring hail, flooding and, in some regions, the potential for tornadoes.
Canada’s top summer storm concerns
Six-in-10 Canadians (61%) fear severe rain and flooding, while nearly half (47%) are concerned about tornadoes, winds, and severe storms. Overall, seven-in-10 (72%) say they are concerned about climate change-related weather, underscoring how extreme weather remains top of mind as Canadians enter the most active months for severe thunderstorms and tornadoes.
Regional differences are pronounced
British Columbians are far more likely than other Canadians to worry about flooding (70%) and landslides or mudslides (41%), while residents of Manitoba and Saskatchewan report the greatest concern about tornadoes, winds, and severe storms (54%). Atlantic Canadians stand apart in their concern about hurricanes and tropical storms (63%), while Quebec and Atlantic Canada lead the country in concern about climate change-related weather (76%). Ontario residents report high concern about flooding (63%), tornadoes and severe storms (49%), and climate change-related weather (74%).
Preparation remains the best defence
With severe thunderstorms, hail, flooding, and tornado activity typically peaking during the summer months, First Onsite says preparation remains one of the most effective ways to reduce property damage and speed recovery when severe weather strikes.
“Every summer storm is different, but the damage often escalates quickly. Water intrusion can happen within minutes, wind damage can compromise roofs in a single event, and once systems fail, costs rise rapidly,” said Jim Mandeville, Senior Vice President, First Onsite Property Restoration. “The good news is that many of the most expensive impacts can be reduced through preparation and fast response.”
To help Canadians prepare for summer storms, First Onsite offers a Severe Weather Management Guide that includes preparedness recommendations, storm safety information and recovery guidance for businesses and property owners.
First Onsite also offers 10 summer storm preparedness tips:
1. Stay informed by monitoring weather alerts and forecasts throughout storm season.
2. Secure outdoor furniture, umbrellas, and loose items before severe weather arrives.
3. Clean eavestroughs, downspouts, and drains to help prevent water buildup.
4. Inspect your roof, windows, and doors for damage that could allow water inside.
5. Trim trees and remove weak branches that could fall during high winds.
6. Test your sump pump and ensure backup power is available if needed.
7. Assemble an emergency kit with essentials such as water, food, medications, and flashlights.
8. Review your insurance coverage and document valuables before a storm occurs.
9. Avoid flooded roads, downed power lines, and other storm-related hazards.
10. Contact restoration and insurance professionals promptly if your property is damaged.
