Government Rebates for Radon Mitigation in Canada

Radon mitigation in Canada typically costs $1,500–$3,000. A handful of provinces and utility programs offer rebates or financial assistance to help offset this, but the programs are limited, subject to change, and require verification before you rely on them.

This page summarizes what's been available as of early 2026. Always confirm directly with the program before counting on a rebate.

Manitoba

Manitoba Hydro's Power Smart program has historically offered one of the strongest radon mitigation rebates in the country, which makes sense given Manitoba has the second-highest indoor radon concentrations in Canada.

Homeowners who install a qualifying sub-slab depressurization system may be eligible for a partial rebate on the installation cost. Amounts have varied by program period. Confirm current amounts at hydro.mb.ca.

The work must typically be done by a certified professional, and a post-mitigation test is often required to confirm the system is working. Apply through Manitoba Hydro's Power Smart portal or contact them directly.

New Brunswick

Efficiency New Brunswick has periodically offered programs that include radon mitigation support, often bundled with broader home energy efficiency incentives that also cover insulation, windows, and heat pumps.

Programs change frequently. Check efficiencynb.ca for what's currently available.

Nova Scotia

Efficiency Nova Scotia has offered retrofit programs that may include support for radon mitigation, particularly when combined with other home improvements.

Confirm at efficiencyns.ca. The organization updates its program offerings regularly, and radon-specific support availability depends on current funding.

Federal programs

As of early 2026, there's no dedicated federal rebate program specifically for radon mitigation. The Canada Greener Homes Grant, which ran from 2021 to 2023, did not cover radon mitigation.

Natural Resources Canada's current program offerings are worth checking, as federal home retrofit programs have changed frequently in recent years.

Municipal and utility programs

Some municipalities and local utilities offer their own incentive programs, particularly in provinces with high radon concentrations. These are worth asking about, especially in Saskatchewan and Manitoba.

When you get quotes from certified professionals, ask if they know of any current rebate programs in your area. Good contractors often track local incentives their customers can access.

What to do before counting on a rebate

Confirm the program is currently active. Programs get paused, run out of funding, or discontinued. Don't budget for a rebate until you've verified it exists right now.
Check that your project qualifies. Most programs require a certified professional, specific system types, and documentation of pre- and post-mitigation test results.
Understand the application process. Some programs need pre-approval before work begins; others are applied for after installation. Know which one you're dealing with before you start.
Keep all your documentation. Receipts, test results, contractor certification numbers, and installation reports will all be needed for a claim.

Is mitigation worth it without a rebate?

Yes. A $2,000 mitigation system that brings your radon from 400 Bq/m³ down to under 100 Bq/m³ is worth doing whether or not a rebate is available. Radon is the second leading cause of lung cancer in Canada. A permanent, effective solution costs less than most major appliances and lasts the lifetime of your home.

The rebates are a bonus, not the deciding factor.
