Ten extreme weather events across Canada’s Prairies this summer have caused widespread damage and more than $1.8 billion in insured losses, according to initial estimates from CatIQ, cited by Artemis.

Artemis reports that the Insurance Bureau of Canada said 2026 has differed from typical Prairie summers, where wind, hailstorms and wildfires usually drive the biggest costs. Instead, heavy rain and flooding caused most of the damage across the three provinces, with Edmonton, Alberta hit especially hard by record rainfall in June and July.

Artemis details that insured losses included more than $40 million tied to a mid-May dust storm from strong wind gusts in southern Saskatchewan and Manitoba, and more than $80 million so far from a prolonged rainfall event that flooded basements, roads, and public spaces in Edmonton. June also saw a series of severe storms, including over $900 million in insured losses from events between June 9 and 10 in Saskatchewan and Manitoba.

The Insurance Bureau of Canada urged governments to take immediate action to reduce exposure to extreme weather as further outbreaks continued, Artemis reported. Additional events included more than $160 million in insured losses from flooding tied to prolonged rainfall in Edmonton and nearby areas between June 20 and 21, and more than $270 million from thunderstorms affecting a broad region between July 4 and 6.
