Homeowners Insurance Ontario: Coverage, Costs & What You Need to Know
Home Insurance, Property Insurance
Published by BrokerUnion Insurance Editorial Team | RIBO-Licensed Ontario Insurance Broker | October 26, 2026
Homeowners insurance in Ontario is a property policy that protects your house, other structures on the property, your belongings, and your personal liability, and pays extra living costs if an insured loss forces you out of your home. It isn't required by Ontario law, but almost every mortgage lender requires it. What a policy covers, and what it costs, depends on your home, your location and the options you choose, especially for water damage.
This guide explains how homeowners insurance works in Ontario, what's covered and what isn't, how flood and sewer backup coverage differ, what affects your premium, and how to compare quotes properly.
What is homeowners insurance in Ontario?
Homeowners insurance is a type of property insurance for people who own and live in a house, such as a detached, semi-detached or townhouse. It typically combines property coverage for the building and your belongings with liability coverage for injuries or damage you're legally responsible for.
It's sold by private insurers through brokers, agents and direct channels. FSRA's role is to make sure those selling insurance are licensed and follow Ontario's property and casualty legislation. Unlike auto insurance, FSRA doesn't approve home insurance rates, because home insurance isn't mandatory in Ontario. That's one reason home insurance prices can vary so much between insurers.
Is home insurance mandatory in Ontario?
No Ontario law requires every homeowner to carry home insurance. In practice, though, mortgage lenders almost always require proof of insurance as a condition of financing, and they usually expect it to stay in force for the life of the mortgage. Even without a mortgage, going uninsured means paying the full cost to rebuild after a fire, replace stolen belongings or defend a lawsuit yourself.
Do I need home insurance if I own my house outright?
It isn't legally required, but your home is likely your largest asset. Without insurance, a single fire or liability claim could cost far more than years of premiums.
What does home insurance cover in Ontario?
A standard Ontario homeowners policy is built from five core coverages, plus optional add-ons:
| Coverage | What it generally protects |
|---|---|
| Dwelling | The main home structure, including attached structures such as an attached garage |
| Other structures | Detached garage, shed, fence and other eligible structures on the property |
| Contents | Personal belongings such as furniture, clothing and electronics, up to policy limits and sublimits |
| Additional living expenses | Temporary living costs, such as a rental and meals, after an insured loss makes the home unlivable |
| Personal liability | Certain claims alleging bodily injury or property damage to others |
| Optional water coverage | Eligible water-related losses, depending on the endorsement purchased |
Policies also come in different forms. A comprehensive form covers all risks except those excluded; a named perils form covers only the risks listed; and some policies combine the two, for example comprehensive on the building and named perils on contents. Always check which form you have.
Does home insurance cover fire, smoke, theft and storms?
Generally, yes. Fire and smoke damage, theft and vandalism, and weather events such as wind, hail and the weight of ice or snow are typically covered on standard Ontario homeowners policies, subject to deductibles, limits and exclusions. Roof damage from a covered storm is usually included; gradual wear on an old roof usually isn't.
Replacement cost vs actual cash value
How your claim is settled matters as much as what's covered.
- Replacement cost pays to repair or replace damaged property with new materials of similar kind and quality, without a deduction for depreciation, subject to policy terms. Many insurers require you to actually repair or replace to receive full replacement cost.
- Actual cash value (ACV) pays the value of the property at the time of loss, after depreciation for age and wear. ACV usually means a smaller payout, especially for older contents.
- Guaranteed or extended replacement cost, where offered, can pay above your dwelling limit if rebuilding costs more than expected, often up to a set percentage or with conditions such as keeping your coverage amount current.
How do home insurance deductibles work?
The deductible is the part of a covered loss you pay before the insurer pays the rest. A higher deductible usually lowers your premium, but means you absorb more of each claim. Some policies have separate, often higher, deductibles for specific perils such as water damage. Choose a deductible you could comfortably pay after a loss, and check whether different deductibles apply to different coverages.
What does home insurance NOT cover?
Exclusions vary by insurer and policy wording, but common ones include:
- gradual damage, wear and tear, rot, mould and lack of maintenance
- continuous or repeated seepage or leakage over time
- overland flooding and sewer backup, unless you purchased those optional coverages
- earthquake, unless added by endorsement
- pests such as insects, rodents and birds
- business activity at home, unless disclosed and endorsed
- losses while the home is vacant beyond the policy's allowed period
- intentional damage by the insured
Read the exclusions section of any policy before you buy, and ask your broker to explain anything unclear.
Does home insurance cover water damage and flooding in Ontario?
It depends on where the water comes from. Water is one of the most misunderstood parts of homeowners insurance in Ontario, and the Insurance Bureau of Canada reported that external water damage, including overland flooding and sewer backup, accounted for nearly a quarter of Canadian home insurance claims in 2025.
| Type of water damage | Typical coverage |
|---|---|
| Sudden and accidental (for example, a burst pipe or failed water heater) | Often covered on standard policies, subject to terms |
| Sewer backup (water or sewage backing up through drains, sewers or a sump pump) | Usually only with an optional sewer backup endorsement |
| Overland water (rivers, lakes, heavy rain or snowmelt entering at ground level) | Only with an optional overland water endorsement, where available |
| Groundwater seepage | Offered by only some insurers, often with limits |
| Gradual leaks or seepage over time | Usually excluded |
Does home insurance cover sewer backup?
Only if you bought the coverage. IBC states that sewer backup damage is covered only where the optional coverage has been purchased, and coverage amounts vary.
Does home insurance cover overland flooding in Ontario?
Only with an optional overland water endorsement. IBC reported that 94% of Canadian homes can now access overland flood insurance, but it often carries limits and may be unavailable in known flood-prone areas.
Because basement flooding can come from either sewer backup or overland water, a homeowner can have one coverage and still be denied for the other. When comparing quotes, ask each insurer which water triggers are covered, the limit for each, and the deductible.
Personal liability coverage for homeowners
Personal liability coverage protects you if you're legally responsible for injuring someone or damaging their property, at home or, under many policies, elsewhere. Think of a guest slipping on an icy step, or a tree from your yard falling onto a neighbour's car. It can pay for legal defence and damages up to your limit.
How much personal liability coverage do I need?
There's no single right number. Many Ontario policies start at around $1 million, and higher limits are available. Consider more if you have significant assets to protect, a pool or trampoline, frequent guests, or rental properties. Homeowners with substantial assets may also consider a personal umbrella policy; BrokerUnion's VIP service reviews higher liability needs alongside the rest of a client's insurance.
Jewellery, art and other valuable belongings
Standard contents coverage often applies lower sublimits to categories such as jewellery, watches, furs, collectibles and fine art. Those limits are designed for typical households and may fall well short for an engagement ring or a valuable collection.
Scheduling an item, meaning listing it individually with a documented value from an appraisal or receipt, can provide coverage at that value and sometimes broader protection, such as coverage for accidental loss. Ask your broker to compare the sublimits on each quote with what you actually own.
What you must tell your insurer
FSRA advises homeowners to disclose full and complete information on their application, including previous claims, renovations and home-based business activities, no matter how small. Here's why each matters.
Do renovations affect home insurance?
Yes. A renovation can increase your home's rebuild cost, so your dwelling limit may need to rise. During construction, the risk also changes: open walls, contractors on site and periods when the home may be unoccupied. Tell your insurer before major work starts.
Does a home business affect home insurance?
It can. Standard homeowners policies often limit or exclude business property and business liability. Clients visiting your home, inventory or business equipment may need an endorsement or a separate business policy. Undisclosed business activity is a common reason for claim disputes.
Does a previous claim affect home insurance?
Often, yes. Insurers look at your claims history, especially water claims, when deciding whether to offer coverage and at what price. A recent claim doesn't always prevent coverage, but it can narrow your options, which is one reason comparing several insurers matters.
Vacant, seasonal and rental properties
Homeowners policies are designed for owner-occupied homes. Different situations need different coverage:
- Vacant homes: Most policies limit coverage if a home is left unoccupied beyond a set period. If you're moving, renovating or travelling for an extended time, ask what conditions apply, such as regular inspections or heating requirements.
- Seasonal homes and cottages: Properties that sit empty part of the year usually need a seasonal or cottage policy that reflects the vacancy, heating and remote location.
- Rental properties: If you rent out a whole property, you generally need landlord or rental property insurance, not a homeowners policy.
What about Airbnb or short-term rentals?
Standard homeowners insurance may not cover short-term rental activity. Renting all or part of your home to paying guests can change the risk significantly, and some insurers require a specific endorsement or a different policy. Tell your broker before you list your home, not after a guest causes damage.
How much does homeowners insurance cost in Ontario?
There's no reliable single price for homeowners insurance in Ontario. Published "averages" from different websites disagree widely because each is based on that site's own quote data, a particular mix of homes, or a particular year. Since FSRA doesn't approve home insurance rates, there's also no regulator-published average to anchor them.
What matters is the price for your home with the coverage you need. Two similar houses on the same street can receive different premiums because of differences in rebuild cost, claims history, roof age, water coverage or the deductible chosen, and because each insurer prices risk its own way.
What affects home insurance rates in Ontario?
| Factor | Potential impact on premium |
|---|---|
| Location | Proximity to fire services and hydrants, local claims history, and weather and flood exposure |
| Home age | Older homes may have older systems that raise the risk of claims |
| Replacement cost | Higher rebuild cost means a higher dwelling limit and premium |
| Construction and systems | Construction type, roof age and condition, plumbing, electrical and heating type |
| Claims history | Recent claims, especially water claims, can raise premiums or limit options |
| Deductible | A higher deductible usually lowers the premium |
| Coverage limits | Higher dwelling, contents and liability limits cost more |
| Water exposure | Basements, sump pumps and flood risk affect the price of water coverage |
| Security systems | Monitored alarms and fire detection may earn a discount |
| Renovations | Updates to wiring, plumbing or roofing may help; ongoing work may change the risk |
| Occupancy | Owner-occupied, rented, vacant or seasonal use is rated differently |
| Bundling | Combining home and auto with one insurer may reduce the total |
How to lower home insurance costs
Without cutting protection you actually need:
- Insure for the right rebuild cost, not market value. Over-insuring wastes money; under-insuring is worse.
- Review your deductible and choose the highest one you could comfortably pay.
- Ask about discounts, such as claims-free, new or updated home, monitored alarm, mortgage-free, or home and auto bundle discounts. Availability varies by insurer.
- Bundle home and auto where it saves money overall. BrokerUnion's guide to home and auto insurance bundling in Ontario explains when bundling helps and when splitting can work better.
- Reduce water risk with a backwater valve, sump pump with backup, water sensors or automatic shut-off valves, and ask whether your insurer credits them.
- Update older systems such as roofs, wiring, plumbing and heating, and tell your insurer when you do.
- Avoid small claims where paying yourself makes more sense, after talking to your broker.
- Compare at renewal, since rates and insurer appetite change.
How to compare home insurance quotes in Ontario
A cheaper quote is only cheaper if it covers the same things. Compare quotes side by side on:
- dwelling limit and how it was calculated
- replacement cost vs actual cash value, and any guaranteed replacement cost
- contents limit and sublimits for jewellery, electronics and collectibles
- liability limit
- sewer backup and overland water: included or not, limits and deductibles
- the main deductible and any separate deductibles
- policy form (comprehensive or named perils)
- additional living expenses limit
- discounts applied and the conditions to keep them
Claims service matters too. FSRA's review of home insurance claims found that different insurers take different amounts of time to settle claims.
Home insurance shopping checklist
- Property address
- Year built
- Square footage
- Construction details (exterior, foundation, number of storeys)

- Desired deductible
- Desired water coverage (sewer backup, overland water)
Why work with an independent insurance broker?
Buying directly from one insurer shows you one company's price and wording. An independent broker compares several, which matters more for home insurance than many people expect, because water coverage, replacement cost terms and sublimits differ so much between insurers.
BrokerUnion is an independent, RIBO-licensed brokerage, and no insurer owns it. When we review a home, our brokers:
- look at the property's rebuild cost, age, systems, water exposure and claims history
- explain what each policy covers and excludes in plain language
- compare available options from the insurance companies and markets we work with, based on the property's risk profile
- recommend endorsements such as sewer backup, overland water and scheduled valuables where they fit
- support you at renewal and through claims
For homeowners who prefer to start online, BrokerUnion's current home insurance page offers a live quote tool that it describes as showing rates from 50+ carriers with no broker fee.

Frequently asked questions
How much home insurance coverage do I need?
Enough dwelling coverage to rebuild your home at today's construction costs, enough contents coverage to replace your belongings, and a liability limit that reflects your assets and risks. A broker can help estimate rebuild cost and review contents limits.
What deductible should I choose for home insurance?
The highest deductible you could comfortably pay out of pocket after a loss. A higher deductible lowers your premium, but only helps if you can actually afford it.
Are there discounts for home insurance in Ontario?
Yes, but they vary by insurer. Common ones include bundling home and auto, claims-free history, monitored alarms, newer or updated homes and being mortgage-free.
Is it cheaper to bundle home and auto insurance?
Often, but not always. Bundling can lower the combined premium, but sometimes splitting policies between insurers costs less. Compare both.
Do I need separate insurance for jewellery or expensive items?
Not a separate policy, usually, but you may need to schedule valuable items on your home policy because standard contents sublimits for jewellery and collectibles are often low.
What is the difference between home insurance and property insurance?
Property insurance is the broader category covering buildings and belongings. Home insurance is property insurance for a residence, and homeowners insurance is the version for owner-occupied houses. Condo, tenant, rental and cottage policies are other types of property insurance.
Can an insurance broker compare multiple home insurance companies?
Yes. An independent broker can compare insurers it has market agreements with and line up their coverage, limits and prices for your home.
What should I ask before buying home insurance?
Ask how the dwelling limit was calculated, whether you have replacement cost or actual cash value, what water coverage is included and its limits, the sublimits for valuables, the deductibles, and what's excluded.
Does home insurance cover roof damage?
Usually, if the damage is sudden and from a covered cause, such as wind or hail. Gradual wear, age-related deterioration and lack of maintenance are typically excluded.
