How do I file a warranty claim with Tarion if my builder won't fix a defect?

Filing a Tarion claim follows a defined process. First, notify your builder in writing of the defect and give them a reasonable opportunity to fix it. Document when you sent the notice and whether the builder responded or made repairs.

If the builder does not respond adequately, you submit a warranty claim to Tarion through the MyHome portal at tarion.com within the applicable warranty period. You provide details of the defect, supporting photographs, and your record of communication with the builder.

Tarion then notifies the builder, who has a prescribed period to assess and fix the issue. If the builder still fails to act, a Tarion field officer will inspect the property. The officer determines whether the defect falls within warranty coverage and, if so, what remedy is required. Tarion can ultimately order or fund the repair directly if the builder remains non-compliant.

Throughout this process, keep meticulous records: photos with timestamps, all written correspondence, any repair estimates you obtain, and records of any costs you incur because of the defect. The burden is on you to demonstrate the defect and its timeline. Having a lawyer review your documentation before you submit a contested claim can improve its outcome.
