House insurance in Ontario

House insurance helps protect your home, belongings, liability, and additional living expenses after an insured loss. A policy can include dwelling coverage, detached structures, contents, personal liability, and optional endorsements for risks such as sewer backup, overland flood, service lines, equipment breakdown, and replacement cost gaps.

No, house insurance is not legally required in Ontario. However, if you have a mortgage, your lender will almost always require it as a condition of the loan, and they’ll want proof of coverage at closing and renewal. Even mortgage-free, going without coverage means absorbing the full cost of a fire, major water loss, or liability claim yourself. 

A standard house policy typically covers four core areas: 

• Your dwelling, meaning the structure of your home, up to your policy limit
• Detached structures such as a garage, shed, or fence 
• Personal property and contents, both at home and often while travelling 
• Personal liability if you’re found legally responsible for injury or damage to others 

It also usually includes additional living expenses if your home becomes unlivable after an insured loss. Sewer backup, overland flood, and guaranteed replacement cost are typically optional add-ons, not automatic. 

Most basic policies exclude or limit coverage for overland flooding, sewer backup, and “guaranteed replacement cost” if inflation outpaces your policy limit. Westland identifies these specific gaps to ensure full protection against Ontario’s climate and economic shifts. 

Ontario home insurance premiums vary based on location, home age, and rebuild value. While the provincial average ranges from $1,200 to $1,500 annually, specialized coverage for high-risk flood zones or heritage homes may differ. 

It depends on the source of the water. Coverage breaks down roughly like this: 

• Sudden, accidental internal water, such as a burst pipe, is often covered under a base policy 
• Sewer backup, water entering through drains or sumps, is excluded unless you add the endorsement 
• Overland flood, water entering at ground level from rain or a nearby body of water, is a separate optional coverage 
• Gradual leaks, seepage, and poor maintenance are generally excluded 

Because water is the most common home claim in Canada, confirming which of these coverages you have is one of the most valuable reviews you can do. 

The two settle a claim very differently: 

• Replacement cost pays to repair or replace damaged property with new equivalents, without subtracting for age or wear 
• Actual cash value pays the depreciated value, subtracting for age and condition, so an older roof or furnace pays out far less 

Most homeowners want replacement cost on the dwelling, and many add guaranteed or extended replacement cost so a rebuild is covered even if it exceeds the policy limit. 

Not necessarily. Many policies are capped at a “stated value.” If inflation drives up the cost of lumber and labor, you may face a “rebuild gap.” Westland offers policies with extended replacement cost coverage to bridge this financial shortfall. 

Your dwelling limit should reflect the cost to rebuild your home today, not its market value, purchase price, or municipal assessment. Market value includes your land, which doesn’t burn down; rebuild cost includes current labour, materials, and bylaw upgrades, which have risen sharply. Because of that gap, regular insurance-to-value reviews matter, since an outdated limit is the most common reason homeowners come up short after a total loss. 

No, not automatically. Both are typically optional endorsements in Ontario: 

• Sewer backup covers water or sewage entering through drains, sumps, or toilets 
• Overland flood covers surface water from rain, rivers, or lakes entering at ground level 

They cover different events, so having one doesn’t mean you have the other. Homes with finished basements or in flood-prone areas usually benefit from both. 

Yes, but older homes need a closer look. Features like knob-and-tube wiring, galvanized or lead plumbing, oil tanks, and older roofs can affect both your eligibility and your price, and some insurers handle them better than others. Heritage and character homes may also cost more to rebuild to original specifications, which is why matching your dwelling limit and insurer to the home matters. 

It depends, and usually only partially. A standard house policy offers limited or no coverage for business property, liability, or clients visiting your home. If you run a business from your home, you’ll often need a home-business endorsement or a separate commercial policy to properly cover equipment, inventory, and liability. Confirm this before assuming a claim would be paid. 

Several factors are within your control: 

• Bundling home and auto with one insurer often unlocks a multi-policy discount 
• Raising your deductible lowers your premium, if you can absorb the higher out-of-pocket cost 
• Monitored alarms, water sensors, and updated wiring, plumbing, and roofing can reduce risk-based pricing 
• A claims-free history and good credit-based factors, where used, can help 

The largest savings usually come from matching coverage to your real risk rather than over- or under-insuring, which an advisor can review with you. 

It depends on how the space is used. A standard owner-occupied house policy may not properly cover a rented unit, a basement apartment, or a short-term rental, and using your home that way without telling your insurer can void a claim. If you rent out any part of your home, including occasional short-term stays, tell your advisor so the policy can be structured correctly.
