No 2027 average exists yet. The latest estimate puts Ontario home insurance at $2,235 a year, up 6.2% (Rates.ca, 2026), and Toronto at about $2,296. Premiums keep rising because of record weather and sewer-backup claims and higher rebuild costs, and they follow rebuild cost, not market value, so falling house prices do not lower them.
This guide is for Ontario homeowners facing a 2027 renewal and for buyers who want to budget for insurance before they firm up a deal. You will see the latest published premium estimates, the real reasons they keep climbing, why a falling house price does not bring your premium down, and the steps that actually shrink an increase.
How much will home insurance cost in Ontario in 2027?
Nobody has published a 2027 figure yet. As of November 2026, the most recent estimate is the Rates.ca Home InsuraMap 2026, which put the average Ontario premium at $2,235 a year, up 6.2% from the year before. Toronto came in at about $2,296 a year, according to the same data as reported by CP24 in August 2026.
Those numbers come from quotes for one sample home: a 2,500 square foot detached house, about 40 years old, with a $500,000 replacement cost. Rates.ca averaged the three lowest quotes with the maximum water coverage available, using quotes as of May 2026. Your home will not match that sample exactly, so treat the figure as a benchmark, not a bill. For a fuller list of city and neighbourhood estimates, see my guide to the average home insurance cost in Toronto and Ontario.
For budgeting, I plan for another increase in 2027 rather than a cut. That is my own cautious view, not a forecast from any insurer. The rest of this guide explains why.
Why do home insurance premiums keep rising in Ontario?
Three forces push premiums up at the same time: more and bigger weather claims, higher costs to rebuild, and more postal codes being rated as high risk for water and wind. The table below pulls the latest published figures together.
| Cost driver | Latest published figure | Who published it |
|---|---|---|
| Insured severe-weather losses in Canada, 2024 | More than $8 billion, the highest on record | IBC, using CatIQ data |
| Toronto and GTA flash floods, 15–16 July 2024 | About $990 million in insured damage | IBC, using CatIQ data |
| Insured severe-weather losses in Canada, 2025 | More than $2.4 billion, the tenth costliest year | IBC, using CatIQ data |
| Ontario and Quebec ice storm, late March 2025 | $466 million (updated March 2026) | IBC, using CatIQ data |
| Catastrophe and wildfire losses, two decades compared | $14 billion in 2006–2015 vs $37 billion in 2016–2025 (inflation-adjusted) | IBC |
| Ontario rebuild costs, Jan 2021 to Jan 2026 | Up 23.8% | Verisk, cited by Rates.ca |
| Ontario postal codes rated high risk | 35.4% for wind and hail; 32.5% for sewer or system backup | Rates.ca 2026 |
| Toronto residential construction prices, Q3 2026 | Up 0.3% year over year | Statistics Canada |

Are weather and water claims really driving Toronto premiums up?
Yes, for most GTA homes water is the biggest single reason. The Insurance Bureau of Canada (IBC), the industry’s national association, says insurers track the number and cost of claims in each neighbourhood. When severe weather causes more claims in an area, the cost to insure homes there can go up, even for owners who never made a claim.
The GTA has had a rough few years. The July 2024 flash floods alone caused close to $1 billion in insured damage, and the March 2025 ice storm now ranks as the sixth costliest weather event in Ontario’s history, according to IBC. IBC also says the average number of catastrophe claims has nearly doubled over the past decade compared with the decade before.
Rates.ca named sewer backup and wind and hail as the biggest drivers of 2026 increases in Ontario. Sewer backup is a city problem as much as a weather problem: older neighbourhoods with combined or overloaded sewers flood basements during intense rain, and finished basements are expensive to repair.
Does the cost to rebuild still push premiums up in Toronto?
It did, and it still sets the size of your coverage, but the pressure in Toronto has eased in the past year. Verisk data cited by Rates.ca shows Ontario rebuild costs rose 23.8% from January 2021 to January 2026. Insurers price your building on what it would cost to rebuild it, so that rise flowed straight into premiums.
Statistics Canada’s latest building construction price index tells a different story for the past twelve months. Residential construction prices in the Toronto area rose only 0.3% from the third quarter of 2025 to the third quarter of 2026, far below the 2.7% average across the 15 cities measured. Statistics Canada did flag new cost pressure: Canadian retaliatory tariffs of 15% to 50% on some U.S. products, including certain steel and aluminum, took effect on 8 September 2026.
My reading, and it is only my reading: in Toronto, a 2027 increase is more likely to come from water and weather claims in your postal code than from the price of lumber and labour. Ask your insurer how it calculated your rebuild amount at each renewal, because that number drives both your premium and your protection.
Why did my premium go up when my house price went down?
Because home insurance covers the cost to rebuild the house and replace your belongings, not the market value of the property. IBC lists replacement cost first among the things that set your rate. In the GTA, a large share of a home’s price is the land, and land cannot burn down or flood away. When market prices fall, the cost of the materials and trades needed to rebuild does not fall with them.
| Area | Detached median, Jan–Oct 2026 | Change vs Jan–Oct 2025 | Estimated 2026 premium |
|---|---|---|---|
| Brampton | $950,000 | −8.9% | $2,140 |
| Etobicoke, district W08 | $1,540,000 | −7.8% | $2,290 (Etobicoke-wide, up 4.1%) |
| Etobicoke, district W06 | $1,179,000 | +1.6% | $2,290 (Etobicoke-wide, up 4.1%) |
| Ontario | Not applicable | Not applicable | $2,235 (up 6.2%) |

Brampton’s detached median fell almost 9%, yet nothing in the published data suggests premiums there fell. In Etobicoke, prices were mixed by district while the average premium rose 4.1%. Prices and premiums simply follow different inputs.

Which parts of Toronto and the GTA are paying more?
Insurers price by postal code, so two houses a few kilometres apart can see very different renewals. From the Rates.ca 2026 data and CP24’s reporting:
- Toronto neighbourhoods along Lake Ontario averaged $2,574 a year, about 15% above the provincial average.
- Birch Cliff and Cliffside in Scarborough averaged $2,336.
- Etobicoke averaged $2,290. Every Etobicoke postal area (the first three characters of a postal code) was rated high risk for sewer backup, and some rose sharply: M9R by 14.7%, M9P by 12.9% and M9A by 9.9%.
- M4W in central Toronto averaged $2,217, just under the provincial average, but rose 13.8%.
- Brampton averaged $2,140 and Hamilton $2,161.
If your area saw a double-digit jump in 2026, it does not mean the same will repeat in 2027. It does mean your insurer now sees your postal code as riskier, and that view rarely reverses quickly.
Is anyone regulating or capping home insurance increases in Ontario?
There is no published cap on home insurance increases that a homeowner can point to. In July 2025, a climate advocacy group, Investors for Paris Compliance, filed a complaint with Ontario’s financial services regulator (FSRA) asking for more transparency. The group said Ontario home insurance rates climbed 84% between 2014 and 2024, while consumer prices rose 28%, and that the regulator publishes statistics on auto insurance trends but nothing comparable for home insurance, as reported by Global News.
Those figures are the group’s own and I have not seen them confirmed by the regulator. The practical point stands: your best protection against a large renewal is shopping the market and reducing your own risk, not waiting for a rule to change.
Will a national flood insurance program lower costs?
Not in time for most 2027 renewals. A National Flood Insurance Program was first promised in the 2019 federal election. In April 2026, the federal emergency management minister said she could not promise it would be delivered in the near future, according to The Canadian Press as published by CP24.
The program is aimed mainly at the highest-risk homes. A 2022 federal task force estimated that residential flooding causes about $2.97 billion in insured and uninsured losses a year, and that almost 90% of flood losses come from the riskiest 10% of homes. Most GTA homeowners are dealing with sewer backup, which is a separate coverage from overland flooding. For lakefront owners, my guide to overland water coverage on a Lake Ontario home goes deeper.
How can I keep my 2027 renewal increase smaller?
You cannot control the weather, but you can control how risky your house looks to an insurer. IBC says insurers ask about these items:
- Electrical: knob-and-tube or aluminum wiring, fuses, or service under 100 amps can raise questions or require an inspection.
- Plumbing: galvanized steel or lead pipes are more likely to leak; copper or plastic can help.
- Roof: insurers generally prefer roofs updated within about 20 years.
- Wood stoves and fireplaces may need an inspection.
- Alarms: monitored burglar, smoke and carbon monoxide alarms are noted.
In Toronto, the City’s Basement Flooding Protection Subsidy pays 80% of eligible costs for work completed on or after 12 November 2025: up to $1,600 per backwater valve (two maximum), $2,250 for a sump pump, $300 for a battery backup, $500 for a plumbing assessment and $400 for capping weeping tiles, to a total of $6,650 per property. My basement flooding subsidy guide walks through the claim. Once the work is done, send the invoice to your insurer and ask whether it changes your sewer backup pricing or limit.
Dropping sewer backup coverage, or cutting its limit, is the fastest way to lower a quote and the fastest way to lose a finished basement. In postal codes rated high risk for sewer backup, a single storm can cause damage far larger than several years of premium savings. Compare quotes with the same water coverage and the same limits, line by line.
Shop at renewal, not mid-term, to avoid cancellation charges. A higher deductible lowers the premium, but only choose one you could pay the week after a loss. IBC also notes that your claims history affects your price, so think twice before claiming a small loss that is close to your deductible.
What should buyers check about insurance before firming up in 2027?
Get a real quote before your conditions expire. Your lender will want proof of insurance before closing, and some homes are slow or costly to place: older houses with original wiring or plumbing, homes with a wood stove, and homes with a rental unit. IBC says insurers will ask whether you rent out all or part of the property, so disclose a basement apartment up front. My guide to the insurance condition in an Ontario offer explains how to protect yourself in the agreement.
Ask the seller for the age of the roof, the electrical panel size, any backwater valve receipts and any past water claims. If you are buying a condo, part of your insurance cost is hidden in the monthly fee, and your own policy has to cover the corporation’s deductible; see my guide to condo insurance and the deductible chargeback.
When clients ask me about insurance, I tell them to stop looking at averages and get two or three quotes on the actual address during the conditional period. A quote that comes back high or with water coverage excluded is information about the house, not just the insurer. I have seen buyers renegotiate, ask for a backwater valve credit, or walk away because of what an insurance quote revealed. In 2027 I would treat that quote as part of the inspection.
What to do next
- Pull out your current policy and write down your premium, deductible, sewer backup limit and rebuild amount.
- Ninety days before renewal, get at least two quotes with identical coverage and limits.
- If you are in Toronto, book a plumbing assessment and apply for the basement flooding subsidy before you renew.
- Fix the cheap red flags first: an electrical inspection, an old hot water tank, missing alarms.
- If you are buying, make insurance a condition and get a quote on the exact address before you waive it.

Frequently asked questions
How much is home insurance in Ontario in 2027?
No 2027 average has been published as of November 2026. The latest estimate, the Rates.ca Home InsuraMap 2026, put the average Ontario home premium at $2,235 a year, up 6.2% from the year before, based on quotes for a sample 40-year-old detached house. Your own 2027 price will depend on your rebuild cost, postal code, water coverage, deductible and claims history.
Why is my home insurance going up so much in Ontario?
Mostly because of water and weather claims and higher rebuild costs. Insured severe-weather losses in Canada passed $8 billion in 2024, a record, and topped $2.4 billion in 2025, according to the Insurance Bureau of Canada. Ontario rebuild costs rose 23.8% from January 2021 to January 2026, per Verisk data cited by Rates.ca. Insurers price by postal code, so a neighbour’s claims can raise your rate.
Will home insurance go down in 2027 in Ontario?
Probably not for most homeowners, though no insurer has announced 2027 rates. Weather losses remain high and many Ontario postal codes are now rated high risk for sewer backup or wind and hail. Toronto construction prices were nearly flat in the year to the third quarter of 2026, which may slow one source of increases. My cautious view is to budget for a rise and shop at renewal.
What is the average home insurance cost in Toronto?
About $2,296 a year, according to Rates.ca data reported by CP24 in August 2026. Toronto neighbourhoods along Lake Ontario averaged $2,574, about 15% above the Ontario average, and Etobicoke averaged $2,290. These are quote-based estimates for a sample detached house with maximum water coverage, so a condo, a newer house or a home with a higher deductible will price differently.
Does a lower house price mean lower home insurance?
No. Home insurance in Ontario is based on what it would cost to rebuild your house and replace your belongings, not on its market value. Land makes up much of a GTA home’s price and does not need insuring. Brampton’s detached median price fell 8.9% in January to October 2026, per TRREB data via REALM, but published premium estimates did not fall with it.
Why is home insurance higher in Etobicoke?
Because Rates.ca rated every Etobicoke postal area as high risk for sewer or system backup in 2026. The Etobicoke average premium rose 4.1% to $2,290, and some areas rose more: M9R by 14.7%, M9P by 12.9% and M9A by 9.9%. Owners there can lower their risk with a backwater valve, which Toronto subsidizes at 80% of cost up to $1,600 per device.
Can I get help paying for a backwater valve in Toronto?
Yes. Toronto’s Basement Flooding Protection Subsidy pays 80% of invoiced costs for eligible work completed on or after 12 November 2025, up to $1,600 per backwater valve with a maximum of two. It also covers sump pumps up to $2,250, battery backups up to $300, a plumbing assessment up to $500 and weeping tile capping up to $400, to a total of $6,650 per property.
Is there government flood insurance in Canada in 2027?
Not yet. A National Flood Insurance Program was first promised in 2019, and in April 2026 the federal emergency management minister said she could not promise it would arrive in the near future, according to The Canadian Press. Until it exists, Ontario homeowners need optional overland flood and sewer backup coverage from their own insurer, which may be limited in known flood zones.
Does renting out my basement raise home insurance in Ontario?
It can, and you must disclose it. The Insurance Bureau of Canada says insurers ask whether you rent out all or part of your property, because tenants change the risk. Hiding a basement apartment can put a claim at risk. Ask your insurer for a policy that covers a rental unit, and require your tenant to carry their own tenant insurance where the lease allows.
How much did severe weather cost insurers in 2025?
More than $2.4 billion in Canada, making 2025 the tenth costliest year on record for severe-weather insured losses, according to the Insurance Bureau of Canada using CatIQ data. The costliest event was the late-March 2025 ice storm in Ontario and Quebec, now estimated at $466 million and ranked as the sixth costliest weather event in Ontario’s history.
