What Happens When Your Contractor Doesn't Honour the Warranty?

Contractor Warranty Issues in Ontario

You've had work done, something has failed within the warranty period, and the contractor isn't responding or is disputing the claim. Here's what your options are.

What the Law Says

In Ontario, there is an implied warranty on construction work that it will be done in a workmanlike manner and be fit for purpose. This exists regardless of what's written in your contract. Additionally, Ontario's Consumer Protection Act applies to residential renovation contracts under $50,000 — it provides additional rights including the right to cancel contracts in certain circumstances.

Document Everything First

Before taking any action, document the defect thoroughly: photos and video with timestamps, written description of the issue, and a timeline of when it appeared. Send a formal written notice to the contractor by email identifying the defect and requesting repair within a specific timeframe (10–14 business days is reasonable).

Escalation Options

If the contractor doesn't respond or refuses: (1) Contact your credit card company if you paid by card — chargebacks are possible for undelivered services. (2) File a complaint with the Better Business Bureau or HomeStars — public complaints often prompt contractor action. (3) Small Claims Court handles disputes up to $35,000 in Ontario — you can file without a lawyer. (4) For larger amounts, consult a construction lawyer about Superior Court or mediation.

Prevention Is Better

The best protection is choosing a contractor with a verifiable track record, a written warranty in your contract, and a real business address. aMaximum Construction provides written workmanship warranties and stands behind our work.
