Insurers Paid $3.7 Billion for Summer 2026 Weather, Pressuring Home Premiums and Water-Damage Deductibles

The useful response to a $3.7 billion summer is not to guess at next year's premium. It is to pull your current policy and declarations page and read three specific lines while nothing is wet.

Whether you carry overland water at all

Overland water coverage responds to water that enters from the surface: heavy rain pooling against the house, a creek or river breaking its banks, fast snowmelt. It is an optional endorsement, separate from sewer backup, though insurers often sell the two together. Availability is broad. About 94% of Canadian residential properties are now eligible for overland flood insurance, and 88% of overland policies cost $300 or less a year, IBC's July flood-market report found. Household take-up rose from 26% in 2017 to 71% in 2023. That still leaves a sizeable share of homes without it.

Your sewer-backup limit, in dollars

Sewer backup coverage pays for water that comes up through floor drains, toilets and sump pits when municipal or private sewers surcharge. It is the line that responded to the Ottawa, Edmonton and Niagara basement floods. The detail to find is the dollar limit, not a percentage or the word "included."

That limit can be far lower than your dwelling coverage. If your sewer backup limit is $25,000, that may be all that is available for the loss, even when your dwelling and contents limits are much higher, an Ontario brokerage's coverage guide explains. Extraction, drying and remediation can consume much of a low limit before flooring, drywall, a furnace or contents are paid for. A finished basement changes the arithmetic entirely.

Your water deductible compared with your all-perils deductible

Most policies carry a standard deductible for most claims and one or more peril-specific deductibles. The deductible for flood insurance is usually higher than for other covered damage, and it may be a fixed dollar amount or a percentage of the claim, according to the Financial Consumer Agency of Canada. To see what the spread can look like at one insurer, Square One lists standard deductible options of $500 to $5,000 and inland flood deductible options that usually range from $2,500 to $25,000, in its published deductible guide. Those are one company's ranges, not a market standard. The point is the gap: a homeowner who remembers a $1,000 deductible may be facing a much larger one on exactly the claim a wet summer produces.

The renewal check, in one table

Hail-resistant roofing in high-risk Alberta areas

The strongest evidence that mitigation is now a rate conversation, not only a risk one, comes from Alberta. A study by MNP LLP for IBC found that homeowners in high-hail-risk areas who install hail-resistant roofing and siding can reduce their premiums by up to 50%, as IBC reported in September. Hail can make up 30% to 68% of the total premium in those areas, which is why the credit can be so large.

The same study found three benefits beyond price. Adopters may get lower deductibles, full replacement-cost coverage on roofs that would otherwise be settled at depreciated value, and removed or reduced coverage caps. An increasing number of insurers also help pay for resilient roofing and siding after a claim.

Read the qualifiers carefully. "Up to 50%" applies in high-risk areas, centred on Calgary and nearby communities. A homeowner in a low-hail area pays a smaller hail share of premium, so the same roof would save less. The study is evidence of what insurers are offering in that market, not a promise from any particular insurer.

FireSmart work and wildfire credits

The wildfire side is real but less quantified. In British Columbia, homeowners whose insurer participates may be eligible for savings after a home assessment and FireSmart certification, FireSmart BC says, naming BCAA and Co-operators as participating insurers. The program does not publish discount amounts. There is no public evidence that FireSmart credits approach the size of the Alberta hail figure, so treat any savings as insurer-specific until you see it on a quote.

Flood protection measures

On the water side, IBC has said insurers offer discounts or better coverage terms for proven flood-protection measures such as backwater valves and sump pumps. No published figure says how large those discounts are, and terms vary by insurer. The more reliable benefit may be in availability and limits rather than price: a protected basement is easier to insure at a meaningful sewer backup limit.
