EmitenTrust.com Record rainfall, flooding and severe weather drove extensive damage and insurance claims across the Prairies

EDMONTON, AB, Sept. 22, 2026 /CNW/ -- Ten extreme weather events in Alberta, Saskatchewan and Manitoba this summer have caused over $1.8 billion in insured damage, according to initial estimates from Catastrophe Indices and Quantification Inc. (CatIQ).

"Once again, the Canadian Prairies have been hit hard by extreme weather, with floods, hailstorms and tornadoes causing extensive damage to homes and businesses," said Aaron Sutherland, Vice-President, Pacific and Western, Insurance Bureau of Canada (IBC). "The growing frequency, severity, and financial cost of these events demands that we rethink how we can better protect communities moving forward and increase investment in resilience now."

How much damage occurred in the Prairies this year?

While wind, hailstorms and wildfires are typically the costliest extreme weather risks in the Prairies over the summer months, this year saw heavy rain and flooding causing the majority of damage across the three provinces. Edmonton, Alberta, was hit especially hard, as the city saw record rainfall in June and July.

1. May 14, 2026: Over $40 million in insured losses across Saskatchewan and Manitoba (Wind)

The rising costs of extreme weather

Over the last decade, insured losses from extreme weather in Canada have averaged $3.7 billion annually, up from annual losses of $1.4 billion in the previous decade and $883 million in the decade before that. Annual losses have increased by approximately 320% since the late 1990s and early 2000s, after accounting for inflation. In 2024, Canada experienced its costliest year on record, with insured losses from extreme weather exceeding $9.4 billion. Households, businesses, governments and communities across the country are increasingly affected by these escalating costs. 

Protecting Canadians from severe weather risks

IBC is reiterating its call for all orders of government to take immediate steps to reduce Canada's exposure to extreme weather events, including:

• Building new homes away from high-risk flood and wildfire zones by strengthening land use planning and restricting development in areas at highest risk
• Providing incentives for homeowners to invest in practical, affordable measures that reduce extreme weather damage and recovery costs
• Requiring cost-effective, community-level mitigation measures, such as flood protection infrastructure and measures recommended by the FireSmart program to help reduce the risk of wildfire damage, when building in high-risk areas is unavoidable
• Investing in resilient infrastructure to protect communities from extreme weather risks, such as flooding
• Strengthening building codes and construction standards to ensure new homes are built with resilient features that reflect current and future climate conditions
• Empowering homeowners, renters and business owners by providing clear, accessible information so they can make informed decisions and take practical steps to mitigate their risks.
