Renovation warranties in Canada: workmanship, manufacturer and legal warranties
What a renovation warranty covers in Canada, why new-home warranty programs do not cover renovations, Quebec Civil Code warranties, Ontario's implied quality warranty and claim steps.
A renovation comes with up to three layers of warranty: the contractor's written workmanship warranty (whatever the contract says), manufacturer warranties on products such as cabinets, fixtures, flooring and windows, and legal warranties that apply whether or not the contract mentions them. New-home warranty programs, such as Tarion in Ontario or home warranty insurance for new homes in British Columbia, generally do not cover renovations of existing homes. In Quebec, the Civil Code of Québec gives the client specific protections: the contractor is liable for poor workmanship reported within one year after acceptance of the work (art. 2120) and for the loss of the work (serious defects) occurring within five years after the work is completed (art. 2118). In Ontario, the Consumer Protection Act, 2002 deems services under a consumer agreement to be of reasonably acceptable quality.
This guide belongs to the pitfalls and official sources overview. For warranty clauses to put in the contract, see the contract checklist; if a warranty claim turns into a dispute, see disputes with a contractor.
Three layers of warranty
| Layer | Who gives it | What it typically covers | Watch out for |
|---|---|---|---|
| Workmanship warranty | The contractor, in the contract | Defects caused by installation: leaks, cracking tile, loose fixtures, doors that do not close | Length (often one year or a few years), exclusions, and whether the contractor will still exist |
| Manufacturer warranty | The product maker | Defects in the product itself | Registration requirements, installation by qualified installers, labour often excluded |
| Legal warranties | The law of your province | Quality of services and goods; in Quebec, Civil Code warranties of the contractor | You may need to prove the defect and act within limitation periods |
Why new-home warranty programs usually do not apply
In Ontario, Tarion administers the statutory warranty for new homes built by licensed builders (who are licensed by the Home Construction Regulatory Authority). In British Columbia, the Homeowner Protection Act requires home warranty insurance on most new homes, with licensing of residential builders through BC Housing. Quebec has a guarantee plan for certain new residential buildings. A kitchen, basement or addition on an existing home is generally outside these programs. Some very extensive projects that rebuild a house may be treated differently; ask the program administrator if your project approaches a rebuild.
Quebec: Civil Code warranties
Quebec renovation contracts are contracts of enterprise under the Civil Code. In summary:
- Poor workmanship (art. 2120): the contractor is liable for poor workmanship existing at the time the work is accepted, or discovered within one year after acceptance.
- Loss of the work (art. 2118): the contractor (and, depending on their role, the architect, engineer and subcontractors) is liable for the loss of the work occurring within five years after the end of the work, for example due to faulty design, construction or soil.
- Acceptance with reservations: when you accept the work, note visible defects in writing; acceptance without reservation may affect later claims about apparent defects.
These articles are summarised here; read the Civil Code on LégisQuébec or consult a lawyer or notary for a specific situation.
Ontario: implied quality and the contract
Under Ontario's Consumer Protection Act, 2002, services supplied under a consumer agreement are deemed to be of a reasonably acceptable quality, and goods supplied with the work are also covered by statutory warranties under sale-of-goods rules. In practice, your written contract's warranty and the evidence you keep (photos, inspection reports, emails) determine how easy it is to get a defect fixed.
Other provinces
Most provinces have consumer protection and sale-of-goods laws that imply some level of quality in goods and services. The details differ, so check your provincial consumer protection office. Limitation periods also limit how long you have to sue: generally two years from when you discovered (or ought to have discovered) the claim in Ontario, British Columbia and Alberta, with ultimate limits, and three years in Quebec. Do not let a warranty discussion run past a limitation deadline.
What a good workmanship warranty clause says
- The length, starting from a clear date (substantial completion or final inspection).
- What is covered: defects in workmanship and materials supplied by the contractor.
- What is excluded: normal wear, owner misuse, owner-supplied materials, damage from other causes.
- How to claim: in writing, to which address, and how quickly the contractor must respond.
- That subcontractors' work is included.
- That manufacturer warranties will be registered or passed to you, with documents.
Making a warranty claim
- Document the defect with dated photos and a description.
- Notify the contractor in writing, quoting the warranty clause, and ask for a repair date.
- Allow reasonable access for inspection and repair.
- Prevent further damage (for example shut off water to a leaking fixture), and keep receipts.
- If the contractor does not respond, send a formal demand letter with a deadline, then consider your options in disputes with a contractor.
- In Quebec, if the contractor is RBQ-licensed, check whether the licence security may apply to poor workmanship found within a year.
Worked example: what a final holdback does for warranty leverage
Illustrative. On a $40,000 bathroom-and-laundry job, the owner agrees in the contract to withhold $1,500 for deficiencies (separate from any statutory holdback) until a listed set of items is fixed. Three weeks after completion, a shower door leaks. Because $1,500 is still unpaid under the contract terms, the contractor returns within days. Without that amount, the owner would rely on the written warranty and goodwill.

FAQ
Is a "lifetime warranty" on a product worth it?
Read what it covers. Lifetime product warranties often exclude labour, require registration and apply only to the original owner.
Does my home insurance cover a contractor's defective work?
Home insurance generally excludes faulty workmanship itself, though it may cover sudden resulting damage depending on the policy. Check with your insurer.
The contractor has closed the business. What now?
Check whether a manufacturer warranty or, in Quebec, the RBQ licence security may help, and get legal advice about claims against the business or its insurer.
