Government Rebates for Radon Mitigation in Canada

The short version

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

This page summarizes what's currently available as of early 2026. Always confirm directly with the program before assuming you qualify.

Manitoba — Most established rebate program

Manitoba Hydro's Power Smart program has historically offered one of the strongest radon mitigation rebates in the country. The program reflects the province's position as having the second-highest indoor radon concentrations in Canada.

What's available: Homeowners who install a qualifying sub-slab depressurization system may be eligible for a partial rebate on the installation cost. Amounts have varied; confirm current amounts at hydro.mb.ca.

Requirements: The work must typically be performed by a certified professional, and a post-mitigation test is often required to confirm the system is working. Documentation requirements vary by program period.

How to apply: Apply through Manitoba Hydro's Power Smart portal or contact them directly.

New Brunswick — Efficiency NB

Efficiency New Brunswick has periodically offered programs that include radon mitigation support, often as part of broader home energy efficiency incentives.

Current status: Programs change frequently. Check efficiencynb.ca for current offerings. At some points, radon mitigation has been bundled with home retrofit programs that also offer rebates on insulation, windows, and heat pumps.

Nova Scotia — Efficiency Nova Scotia

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

Current status: Confirm at efficiencyns.ca. The organization periodically updates its program offerings, and radon-specific support may be available depending on current priorities.

Federal programs

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

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

Municipal and utility programs

Some municipalities and local utility providers offer their own incentive programs, particularly in provinces with high radon concentrations. These are worth asking about, especially in Saskatchewan and Manitoba where awareness and professional networks are more developed.

When you get quotes from certified professionals, ask if they're aware of any current rebate programs in your area — good professionals often know about local incentives their customers can access.

What to do before relying on a rebate

Confirm the program is currently active. Programs get paused, funded out, or discontinued. Don't budget for a rebate until you've verified it's available.
Verify 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 require pre-approval before work begins; others are applied for after installation. Know which one you're dealing with.
Keep all documentation. Receipts, test results, contractor certification numbers, and installation reports will all be needed for claims.

Is mitigation worth it without a rebate?

Yes. A $2,000 mitigation system that brings your radon from 400 Bq/m³ to under 100 Bq/m³ is worth doing regardless of whether 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.

The rebates are a bonus, not the reason to act.
