After four straight years of a hardening property catastrophe reinsurance market, Canadian insurers appear headed toward relief in 2026, a shift brokers should factor into renewal conversations now, even as a fresh wave of severe weather events continues to test the market's capacity to absorb losses.
Canada's property catastrophe reinsurance market has been in a firm or hardening cycle since 2021, with rate-on-line increasing each year through a particularly difficult 2025 renewal, according to Guy Carpenter Canada's 2026 executive outlook. But with limited catastrophe losses globally in 2025 and reinsurers broadly seeking growth, Guy Carpenter said most signs now point to a softening reinsurance market for Canadian insurers heading into 2026.
For brokers negotiating renewals on catastrophe-exposed commercial property or high-risk residential accounts, that's a meaningful shift from the conditions of the past two renewal cycles, and a reason to push back harder on premium increases than may have been possible in 2024 or 2025.
That said, softening reinsurance costs will take time to filter through to what carriers charge policyholders. Canadian home insurance premiums are estimated to have risen between roughly 7% and 12% on average in 2026, with some high-risk postal codes seeing increases of 15% or more at renewal, as insurers continue passing through the combined effect of prior catastrophe losses, the harder reinsurance market of recent years and rising rebuild costs tied to materials and labor inflation.
Brokers can use that range as a benchmark: a renewal coming in meaningfully above it, particularly outside a headline disaster zone, is worth investigating and potentially shopping.
The renewal outlook is complicated by a summer of record catastrophe frequency. CatIQ, the Toronto-based organization providing industry-wide catastrophe insurance data and a subsidiary of PERILS, said 10 new events were declared across Canada in June and July alone, matching the pace of 2023, the current record year for event frequency, which went on to record 26 events for the full year after nine more struck in August. With 14 events declared so far in 2026, CatIQ director Caroline Floyd said it remains to be seen whether the year will surpass 2023's record.
For brokers, that pattern matters more than any single event total. It suggests insurers are absorbing cumulative losses from many geographically dispersed, moderate-sized events rather than one blockbuster catastrophe, meaning clients well outside a headline disaster zone may still see rate pressure at renewal.
That's a different conversation to have with clients than pointing to a specific storm or wildfire, and one brokers should be prepared to explain in terms of frequency rather than severity.
CatIQ also finalized its loss estimate for the Calgary, Alberta hailstorm of August 5, 2024, Canada's largest hail catastrophe, at $3.349 billion, little changed from the one-year estimate of $3.293 billion. Floyd said more than 95% of reported claims are now resolved, up from 86% at the one-year mark, and that the pace of resolution actually improved relative to the 2020 Calgary hailstorm despite nearly double the claim volume.
For brokers with clients still working through a large or complex claim elsewhere, that data point offers a credible, evidence-based way to reassure a frustrated client that a slow-moving claim reflects event scale rather than insurer failure.
CatIQ separately issued an initial $374 million estimate for a severe thunderstorm that brought flash flooding and tornadoes to southern Ontario and Quebec between June 30 and July 3, 2026, with a second update due August 17, and raised its 45-day estimate for June's Montreal flooding slightly to $411 million.
Brokers heading into catastrophe-exposed renewals this year face two competing signals: a softening reinsurance market that could ease pricing pressure over time, and a record pace of frequent, moderate-sized events that continues to strain insurer loss experience in the near term.
Brokers who frame renewal conversations around both, rather than assuming last year's hard-market conditions will simply repeat, will be better positioned to negotiate effectively and set realistic expectations with clients.
