New home in Ontario? Your Certificate of Analysis may help with a Tarion warranty claim. (Ontario only.) Tarion's stance is that a radon result at or above 200 Bq/m³, backed by a long-term test from a C-NRPP-certified lab, can support a new-home warranty claim — and that's exactly the kind of report we provide. We can't guarantee that you or your home will qualify — eligibility depends on your home's warranty coverage, your result, timing, and Tarion's own assessment. Please confirm directly with Tarion at tarion.com before relying on it. One order = one household. If you're gifting or giving kits to another household, please place separate orders so reminders and results stay organized.
