Usually not when the damage is gradual. Canadian home policies are written for sudden and accidental events, so settlement, foundation cracking, rot and slow sag are normally excluded, while structural damage from a covered event such as fire or a tree falling in a storm can be paid. A newer house may still be inside a provincial new-home warranty that covers structure.
- Insurance follows the cause of the damage, not its size: a sudden covered event can be paid, slow movement usually cannot.
- New-home warranties cover major structure for 10 years in Alberta and British Columbia, 7 in Ontario and 5 in Quebec, and the coverage stays with the house when it sells.
- Repairs to the home you live in are personal costs; on a rental, CRA separates repairs that restore from improvements that add lasting value.
- Photograph, date and keep everything before repairs start, because the cause you can prove is what a claim turns on.
01 /Does home insurance cover structural damage?
Home insurance pays for structural damage when an insured peril caused it, and usually refuses when time, soil or wear caused it. That single idea explains most claim outcomes. A joist burned in a kitchen fire and a rafter snapped by a falling spruce are losses the policy was written for. A floor that crept downward over forty years, or a basement wall that bowed a little more each winter, is the kind of slow change insurers treat as maintenance or as an excluded condition.
The Insurance Bureau of Canada (IBC) describes comprehensive policies, which cover every risk except the exclusions listed, and named-perils policies, which cover only the risks written into them. Either way, the exclusions matter most for structure. IBC lists earth movement such as landslides and earthquakes as generally excluded (earthquake cover can be added), gives rotting and gradual deterioration as examples of expected wear that is not an insured peril, and names insect and rodent damage among common exclusions. In its guidance on trees, IBC notes that most policies exclude cracking, shifting or settling of a foundation, and that root damage is gradual rather than sudden.
| Cause of the damage | Usual outcome | Why |
|---|---|---|
| House fire | Typically covered | Fire is a core insured peril; charred framing is part of the rebuild |
| Tree blown or struck onto the house | Generally covered | Wind and lightning are insured perils; IBC says debris removal is usually included |
| Tree roots cracking a foundation | Not covered | Gradual damage, not a sudden event |
| Settlement, shifting or foundation cracking | Usually excluded | Listed exclusion in most policies |
| Earthquake | Excluded unless added | Earth movement exclusion; optional earthquake cover exists |
| Rot from a slow leak, sagging from creep | Not covered | Gradual deterioration is expected wear |
| Carpenter ants, termites, rodents | Usually excluded | Common insect and rodent exclusion |
| Sewer backup or overland flood | Only with optional cover | Both are usually add-on endorsements |
| A renovation that cut a joist or removed a wall | Ask; often a dispute | Workmanship is commonly excluded; the contractor's liability insurance may be the route |
Treat that table as a map, not a promise. Two owners with the same crack can get different answers because their policy forms differ; only your actual wording settles it.
02 /Why is settlement excluded, and what about a sudden collapse?
Insurers price policies around events that are unpredictable for any one house. Settlement, frost pressure, rot and creep are predictable enough that they are treated as the owner's responsibility, much like replacing a roof at the end of its life. That is why a claim for a bowing wall is normally declined even when the repair is expensive and the owner did nothing wrong.
The harder cases sit in between: a ceiling that drops without warning because rot was hidden inside a wall, a roof that fails under a heavy snowfall, or a floor that gives way after a pipe leaked for months unseen. Some policy wordings address collapse or the weight of snow and ice specifically, and some treat hidden damage differently from visible neglect. Read the definitions section, then ask the broker to point to the clause that applies. Do not assume either answer.
The engineer's opinion on cause often decides these claims. Ask the engineer to describe what they found and what most likely caused it, plainly and honestly; a report written to steer a claim is worth less than no report. The engineer's reports guide explains what a sound cause statement looks like.
03 /Does a new-home warranty cover structural defects?
If the house is new enough, a provincial new-home warranty may pay where insurance will not, because warranties cover defects in how the house was built rather than sudden events. Coverage periods for structure are set by each province, and in the four provinces below the coverage is attached to the home, so a buyer of a resale house can inherit whatever time is left.
| Province | Structural coverage | Follows the house on resale? |
|---|---|---|
| Alberta | 10 years on major structural components: the frame, including the roof's structural integrity, and the foundation (homes with building permits after February 1, 2014) | Yes, until coverage expires |
| British Columbia | 10 years on structure under the 2-5-10 home warranty insurance | Yes, until coverage expires |
| Ontario | 7-year major structural defect warranty from the date of possession | Yes, for the rest of the term |
| Quebec | 5 years after the end of work for faulty design, construction or execution and for unfavourable soil | Yes, for the rest of the term |
| Other provinces and territories | Programs and terms differ | Confirm with the provincial program or the builder's warranty provider |
A structural warranty is narrower than it sounds. Ontario's program describes a major structural defect as a crack, distortion or displacement of a load-bearing element that affects structural integrity or significantly affects use of the home. Drywall cracks, squeaks and minor floor unevenness are usually handled, if at all, under shorter workmanship coverage that may already have ended. Alberta's program defines major structural components as the frame, including the roof's structural integrity, and the foundation.
- Find the paperwork
Ask the seller or builder for the warranty certificate or policy, the provider's name and the possession or completion date. In British Columbia, BC Housing's New Homes Registry shows whether a home has coverage and who built it.
- Work out the deadline
Count from the date the program uses, such as possession in Ontario or completion of work in Quebec. Claims made after coverage ends are normally refused.
- Document and notify in writing
Photos with dates, measurements, and a short description of when you first noticed the problem. Follow the provider's claim form and keep proof of submission.
- Let the provider see it first
Unless something is unsafe and needs emergency support, avoid repairing before the provider's inspection. Temporary shoring to keep people safe is different from a permanent fix.
04 /Are structural repairs tax deductible in Canada?
Not for the house you live in. Repairs to a principal residence are personal spending, however large. The answer changes for rental property, where the Canada Revenue Agency (CRA) sorts spending into current expenses, usually deducted in the year, and capital expenses, generally claimed over time through capital cost allowance.
CRA's criteria include whether the spending gives a lasting benefit, whether it restores the property to its original condition or improves it beyond that, whether it replaces part of the building or buys a separate asset, and how large the cost is relative to the property. CRA also says repairs to get a newly bought property ready for use, and repairs made in anticipation of selling, are capital.
| Situation | Leans toward | Reason from CRA's criteria |
|---|---|---|
| Sistering cracked joists back to their original capacity | Current | Restores the building to its original condition |
| Adding a beam so a wall can come out for an open plan | Capital | Improves the property beyond its original state |
| Structural repairs to make a just-purchased rental usable | Capital | Repairs to prepare newly acquired property for use |
| Structural repairs done to prepare the property for sale | Capital | Repairs made in anticipation of selling |
| Major repair that is large relative to the property's value | Look closely | Relative value is one of CRA's tests |
Basement suites and home offices add wrinkles, so ask an accountant. Keep invoices that separate structural work from finishes, because the two can be treated differently.
05 /How do homeowners pay for structural repairs?
Most owners fund structural repairs from savings or borrowing. Canada Mortgage and Housing Corporation (CMHC) lists the usual routes: savings or a credit card, a personal loan, a personal line of credit, a secured line of credit or home equity loan, refinancing the mortgage, and financing the improvements when you buy. CMHC points out that credit card rates can top 18%, that secured borrowing brings lower rates but set-up costs such as legal fees, and that setting money aside for surprises is wise. For a purchase, CMHC's Improvement mortgage loan insurance lets a lender base the loan on the as-is value plus the cost of improvements, subject to its conditions.
| Scope | Examples | Planning range |
|---|---|---|
| Engineering | Site visit and letter, or a design with stamped drawings | $500–$3,500 for most house jobs |
| Minor structural | A few sistered joists, a sinking post replaced with a footing | $1,000–$5,000 |
| Moderate structural | A new beam line, wall bracing, a bungalow wall removal | $5,000–$20,000 |
| Major structural | Underpinning, a wall rebuild, a fire or flood structural rebuild | $20,000–$60,000+ |
| Temporary shoring | Holding a floor or beam line while the cause is found | $1,000–$5,000 |
Two cautions. Contractor financing can be convenient, but compare the total cost of borrowing, and never let a payment plan decide how much of the engineered repair gets built. And in a condominium, the structure is usually managed by the corporation as common property or under its bylaws, so read the declaration and talk to the board or manager before paying for anything structural yourself. The full ranges are in the structural repair cost guide.
06 /What should you document before calling the insurer or warranty provider?
- Make it safe first. If a floor, ceiling or beam is moving, keep people away and arrange temporary support; see emergency shoring. Insurers generally expect you to prevent further damage.
- Photograph before anything moves. Wide shots for context, close-ups with a tape measure in frame, and the date. Photograph again after shoring goes in.
- Write a timeline. When you first noticed it, what changed and when, and any event such as a storm, leak, heavy snowfall or renovation.
- Keep damaged material. A cracked joist or a failed connector is evidence. Ask before it goes in a bin.
- Get the cause assessed. A structural engineer's letter on cause and extent is often what the adjuster or warranty inspector relies on; see what a structural engineer does.
- Ask for the wording. Request the policy form or warranty terms in writing and the specific clause behind any refusal.
A clear record also helps if the answer is no, because the same photos, timeline and engineer's letter become the basis for pricing the repair and, later, for showing a buyer that the problem was dealt with properly. Rate your signs with the Structural Warning Sign Triage, and if you want help lining up an engineer or a repair quote, send a request with your photos.

FAQQuestions people ask
Will my home insurance pay to fix a sagging floor?
Rarely, if the sag developed slowly from creep, undersized framing or settlement, because gradual deterioration is not an insured peril. If a sudden covered event such as a fire or a burst pipe damaged the framing, the structural repair can form part of that claim.
Does a new-home warranty cover foundation settlement?
It can, if the home is still inside the structural coverage period and the settlement amounts to a defect in the foundation or a load-bearing element as the program defines it. Minor cracking within normal tolerances usually does not qualify.
Is a new-home warranty still valid after the house is resold?
In Alberta, British Columbia, Ontario and Quebec, yes: the programs say coverage stays with the home until the term ends. Ask the seller for the warranty documents and the start date before you firm up an offer.
Can I deduct a structural repair on my income tax?
Not on the home you live in. On a rental, CRA treats repairs that restore original condition as current expenses and improvements, or repairs made to prepare a newly bought property or for a sale, as capital expenses. An accountant should confirm how your repair is classified.
Who pays if a contractor damaged the structure during a renovation?
Start with the contractor and their liability insurer, since workmanship problems are commonly excluded from the owner's home policy. Put the problem in writing, get an engineer's letter on cause, and ask your broker whether any resulting damage is covered.
Who pays for structural repairs in a condo?
Usually the condominium corporation, because structure is normally common property or managed by the corporation. The declaration and bylaws decide, so read them and raise it with the board or property manager in writing.
Will insurance pay for the structural engineer's report?
Sometimes, when the loss is covered and the adjuster needs an engineer to scope it; ask the adjuster before hiring. For excluded problems such as settlement or rot, the owner normally pays the engineer.
