What financial help is there for radon in Canada, and in what order should I apply?

There is no federal grant for radon. Help comes from a Canadian Lung Association grant, programs run by provinces and territories, a tax credit in Saskatchewan, loans, and Ontario’s new home warranty. Each program sets its own rules, and some of those rules clash on timing. The order you apply in can decide whether you qualify. Find the programs where you live.

Free and loaned test kits come from community programs, lung associations and libraries

Free kits come from the 100 Radon Test Kit Challenge in participating communities and from LungNSPEI in Nova Scotia. The White Ribbon program gives them to people with lung cancer and their families. Some libraries lend radon monitors. There is no federal kit program, and Health Canada points people to Take Action on Radon.

• The 100 Radon Test Kit Challenge, from CARST and the Canadian Cancer Society with Health Canada funding, runs for 2025 and 2026.
• Most challenge communities give kits free; some charge a low fee.
• The White Ribbon program gives free kits to people diagnosed with lung cancer and their family members.
• Libraries lend radon monitors in Nova Scotia, and in Saskatoon and Regina through Lung Saskatchewan’s directory.

A White Ribbon detector is returned after at least 91 days. A library monitor is a screening tool, not a long-term test. See which kit gives a long-term result.

Test first: the grants that pay for mitigation need a long-term result above 200 Bq/m³

The Canadian Lung Association’s Lungs Matter grant and Nova Scotia’s Radon Reduction Grant both ask for a long-term result before you apply. Lungs Matter wants results from at least 90 days, from a C-NRPP certified kit, above 200 Bq/m³.

Lungs Matter

Up to $1,500

The Canadian Lung Association's grant toward home radon mitigation, for people with a lung cancer diagnosis or a low or moderate income household. Completed work is not eligible.

Canadian Lung Association, Lungs Matter: Radon Mitigation Support (updated 1 September 2026)

Copy citation

Nova Scotia’s grant wants long-term results above 200 Bq/m³ from a C-NRPP certified detector. Funding is limited, so qualifying does not guarantee a grant. See how to run the long-term test a grant asks for.

Get quotes from C-NRPP certified professionals before you apply

Both grants ask for quotes when you apply. Lungs Matter wants a quote from a C-NRPP certified mitigation professional. Nova Scotia wants quotes from at least two C-NRPP certified mitigation companies.

Nova Scotia grant

Up to $2,500

Nova Scotia's Radon Reduction Grant toward mitigation, run by LungNSPEI, for owners with household income under $100,000. It is paid to the contractor, and completed work is not reimbursed.

LungNSPEI, Radon Reduction Grant Program

Copy citation

Both grants check income through the latest CRA Notice of Assessment from everyone on title. Lungs Matter is for a lung cancer diagnosis or a low or moderate income household. Its income caps differ by province, such as $105,100 in Ontario. Nova Scotia’s grant, run by LungNSPEI separately from Lungs Matter, needs household income under $100,000 on line 15000. See how to find and check a certified installer.

Lungs Matter and Nova Scotia refuse finished work, so apply before the work starts

Four programs want your application before any work is done. Caring Breaths wants receipts after the work. Check each rule before you book an installer.

• Lungs Matter and Nova Scotia’s Radon Reduction Grant: quotes first; completed work is not eligible.
• Yukon’s Home Repair Program: work done before written approval is not covered.
• Quebec’s RénoRégion: work must not start before the regional county municipality (MRC) issues the eligibility certificate.
• Lung Saskatchewan’s Caring Breaths: receipts only, no quotes or estimates; closed now, and its page says it returns in 2026.

If you could use more than one program, the order you apply in decides whether you qualify for each. See every program’s rules, status and date.

Tax credits and on-bill loans exist in some provinces, not all

Saskatchewan’s Home Renovation Tax Credit lists a permanent radon mitigation system as a qualifying expense. A tax credit lowers the income tax you owe and does not pay the contractor. A $3,000 system gives $210 back, or $262.50 for a senior.

Saskatchewan tax credit

Up to $420

Saskatchewan's Home Renovation Tax Credit, which names a permanent radon mitigation system: 10.5% of eligible costs above $1,000, up to $420, or $525 for seniors.

Manitoba Hydro’s Home Energy Efficiency Loan covers radon mitigation up to $5,000, repaid on your energy bill over five years at 6.20%. Yukon’s government states radon mitigation qualifies for its Home Repair Program, a loan of up to $70,000. Vaudreuil-Dorion, Quebec, pays back 50% of a system, up to $500, for results above 200 Bq/m³ in 2026. Other home repair programs may not name radon; our funding dataset marks each one as named, not named or not verified. See what the system itself costs.

Ontario’s new home warranty covers radon only when the builder is at fault

Tarion’s new home warranty covers radon above 200 Bq/m³ only where the builder is at fault. Repairs are owed where the level results from a Building Code violation or a defect in the builder’s work or materials. This is warranty coverage under article FH 1.19, and neither a grant nor a rebate.

Tarion radon coverage

Up to $50,000

Ontario's new home warranty covers radon repairs up to $50,000 where the purchase agreement was signed after 1 February 2021, and $15,000 before. The cause must be a Building Code violation or a builder defect.

Tarion, Construction Performance Guidelines, article FH 1.19 Radon Exceeds Acceptable Levels

A claim needs a long-term test of 91 days or more in the lowest level. Tarion accepts what it calls an “approved do-it-yourself radon test kit”, or a certified professional. Coverage lasts seven years from original possession and stays with the home. A resale buyer must contact Tarion to be added to the file. See the funding cards for your province.
