A new TD Economics report highlights a growing national challenge, while Ontario has experienced the greatest number of catastrophic weather events since 1983, Alberta has endured the largest share of insured losses.
Ontario accounted for about 36% of catastrophic events between 1983 and 2024, followed closely by Alberta at 32%. But Alberta’s impact is far deeper. The province represents 42% of all insured catastrophic losses in Canada over the same period — more than Ontario (24%) and Quebec (17%) combined.
Alberta’s outsized share is driven by five billion-dollar disasters since 1983 — including two wildfires, two hailstorms and a major flood — which together account for half of the province’s catastrophic insured losses and more than one-fifth of the national total.
For investors, developers and property owners, these findings reinforce the importance of risk-adjusted planning, resilient design and insurance-aware underwriting in Alberta’s commercial real estate market.
