Home insurance nearly quadrupled in 20 years — and Statistics Canada just explained why

A recently released Statistics Canada study on extreme weather shows that homeowners’ insurance premiums in Alberta climbed almost 392% between December 2005 and December 2025 — the largest increase of any province and more than double the national average of 174.4%, over the same period. The study is the most authoritative reckoning yet of how extreme weather is fundamentally repricing the cost of owning a home in Canada.

And this repricing is no longer a problem just for Alberta residents.

Why Alberta became the most expensive province to insure

There isn’t one isolated reason for Alberta’s astronomical premium increase, explains Statistics Canada economist Marisa McGillivray, who led the study.

“There’s just been an overall uptick in the frequency, as well as the severity, of extreme weather.”

Alberta sits in the geographic crosshairs of hailstorms, wildfires and convective storms — particularly in and around Calgary — and the financial consequences are compounding.

The data proves McGillivray’s point. In just a single 30-day window in the third quarter of 2024, four catastrophic events struck regions across Canada, costing insurers a combined $7 billion. The Calgary hailstorm alone — golf-ball-sized hail that tore through the city in August 2024 — generated $3 billion in insured losses in roughly one hour. The Jasper wildfire, the same year, added another $1.1 billion in claims.

The result? Canada’s property and casualty (P&C) insurers recorded net underwriting losses on home insurance in both 2023 and 2024. In other words, some Alberta insurers were paying out more in claims than they collected in premiums. With most insurers following a fiduciary duty to shareholders, these losses can’t stay on the insurer’s balance sheet and end up being transferred to policyholders at renewal time — typically spread across the entire provincial pool of homeowners, whether or not those policyholders ever filed a claim.

The national trend: Your province’s insurance versus general inflation

Alberta residents aren’t the only ones feeling the pressure.

Between December 2019 and December 2025, Canadian home insurance premiums rose 45%, outpacing the all-items Consumer Price Index, which rose 21% over the same period. That gap — insurance inflation running more than twice general inflation — is the financial pressure that Canadians are feeling when it comes to their home insurance policy renewal.

According to Statistics Canada CPI data, Manitoba, Nova Scotia and Saskatchewan all exceeded the national average home insurance increase of 38.6% in the five-year period from December 2020 to December 2025. In 2024, total insured weather losses in Canada hit $9.4 billion — a figure that the Insurance Bureau of Canada (IBC) calls the highest ever recorded, and roughly 12 times the annual average seen in the decade between 2001 and 2010.

“Natural disasters are reshaping the home insurance landscape for Canadians from coast to coast,” said Liam McGuinty, vice-president of federal affairs at IBC in a mid-June call-for-action. “The increased frequency and severity of extreme weather events are driving up claims costs and putting pressure on home insurance premiums across the country.”

How climate repricing works — and why homeowners with no claims are still seeing hikes

Insurance pricing operates on a pooling principle: The losses of the few are distributed across the premiums of the many. When catastrophic weather events hit with greater frequency and severity, the math changes for everyone in the pool — even homeowners who have never filed a claim.

Beyond the claims themselves, rebuild costs have surged. Statistics Canada’s residential building construction price index rose 69.4% between the fourth quarter of 2019 and the fourth quarter of 2025. That means a home that would have cost $400,000 to rebuild six years ago now costs closer to $680,000. If a homeowner’s dwelling replacement value has not been updated to reflect that increase, they may be significantly underinsured — and find out only after a claim.

Reinsurance costs — what insurers pay to insure their own risk — also spiked sharply in 2023 and remain elevated. That upstream cost increase flows directly into retail premiums for Canadian homeowners.

What comes next if the trend continues

The IBC has warned that around 10% of Canadian households already face flood risk so elevated that private flood insurance is unavailable or unaffordable. A federal flood insurance program was pledged with an April 2026 launch date, but as of mid-2026, there’s been no launch and no update.

A 2025 report from the Canadian Climate Institute estimated that without restrictions on building in high-risk zones, more than 540,000 homes could be built in flood-prone areas by 2030, adding an estimated $2 billion in annual damages. The same institute calculated in 2026 that $4 billion in annual proactive infrastructure investment could yield $5 to $10 billion in avoided losses — but that investment has not yet materialized at scale.

For homeowners in wildfire interface zones, high-risk postal codes — particularly in northwest Calgary, parts of Atlantic Canada and the B.C. interior — the concern is not just rising premiums but shrinking availability. Some insurers are quietly reducing their exposure in specific regions, which can leave homeowners without renewal options from their existing insurer.

What homeowners can do now to reduce premium exposure

Rising premiums do not mean homeowners are without options.

Several actions can directly affect what you pay at renewal — and how well you are actually covered if disaster strikes.

Review your dwelling replacement value. Rebuild costs are up roughly 70% since 2019, according to Statistics Canada data. If your coverage limit has not been updated to reflect this, you may be underinsured — a gap that matters most precisely when you need coverage.
