What does the warranty cover and for how long?

Coverage is tiered by defect type, with the longest tier for major structural defects. Each tier has its own claim window and statutory form — check which applies to your defect before doing anything else.

Do I claim against Tarion or the builder?

Raise it with the builder first, then submit a statutory warranty form to Tarion within the window. Tarion assesses and can conciliate; it does not replace a civil claim for matters outside the warranty.

Can I appeal a Tarion decision?

Yes, to the Licence Appeal Tribunal, within the deadline stated in the decision.

Is my builder licensed?

Builder and vendor licensing moved to the Home Construction Regulatory Authority in 2021. Verify licensing with the HCRA before signing a purchase agreement.
