Ontario Home Warranty

Due to homeowner's concern with radon gas as a potential health hazard within their homes, Tarion is addressing this serious issue.  The Tarion Home Warranty will cover the costs of mitigating radon from homes, provided a radon test proves a high level of radon. If radon gas within a home exceeds Health Canada’s acceptable levels of 200Bq/m³, then Tarion will cover the costs required to mitigate a home up to a limit of $15,000.
