Ensuring your home is safe from radon exposure is crucial for your family’s health. There are several programs across Canada that offer financial assistance to help homeowners test for and mitigate high radon levels.
The Lungs Matter: Home Radon Mitigation Grant Program offers financial assistance to homeowners facing elevated radon levels, providing up to $1,500 towards mitigation efforts.
Applicants must meet one of the following conditions:
Income threshold varies by province, but in Ontario, household income may not exceed $105,100 (for a family) $32,400 (for an individual).
The Ontario Renovates Program provides financial assistance to low- and moderate-income homeowners for essential home repairs and accessibility modifications. However, the program’s availability, funding amounts, and eligibility criteria can vary significantly across different regions in Ontario. Each regional municipality administers the program independently, tailoring it to address local housing needs and priorities. Therefore, homeowners are encouraged to consult their specific regional program guidelines to understand the exact details and application procedures applicable to their area.

In Ontario, the Tarion Warranty Corporation offers protection for homeowners against excessive radon levels in new homes.
For new homes in Ontario, Tarion provides a comprehensive warranty that includes coverage for radon gas infiltration. This coverage spans seven years from the date of possession and is applicable if radon concentrations exceed Health Canada’s guideline of 200 becquerels per cubic metre (Bq/m³). Notably, Ontario is among the few jurisdictions in Canada that includes radon remediation as part of its statutory new home warranty.
For agreements of purchase and sale signed on or after February 1, 2021, the maximum coverage for radon remediation under the Tarion warranty is $50,000. For agreements signed before this date, the coverage limit is $15,000.
Homeowners are responsible for testing their homes for radon. This can be done using do-it-yourself radon test kits available at hardware stores or by hiring certified professionals. Health Canada recommends long-term testing, typically over a period of at least three months, to obtain accurate results.
If test results indicate radon levels above 200 Bq/m³, homeowners should:
Submit a warranty claim to both the builder and Tarion using the appropriate warranty form.
Provide test results from a long-term radon test (minimum three months) conducted with a device or by a professional certified through the Canadian National Radon Proficiency Program (C-NRPP).
Upon receiving a valid claim, the builder is obligated to implement measures to reduce radon levels, typically by installing a radon mitigation system. If the builder fails to act, Tarion will intervene to ensure the necessary remediation is completed.
It’s important to note that the Tarion warranty does not cover:
Costs incurred for initial radon testing.
Personal injury or health issues resulting from radon exposure.
Damage to personal property caused by radon.
The Tarion Warranty offers significant protection for new homeowners in Ontario against elevated radon levels. By understanding the coverage details and promptly addressing any radon concerns, homeowners can ensure a safe living environment.

While radon disperses harmlessly outdoors, it can accumulate to dangerous levels indoors, especially in basements and lower levels of buildings. Prolonged exposure to elevated radon levels increases the risk of lung cancer. In fact, radon is responsible for about 16% of lung cancer deaths and is the leading cause of lung cancer in non-smokers, second only to smoking overall.
