About Radon in Manitoba

Last updated: March 2026

Manitoba has above-average radon risk, with Winnipeg frequently recording levels that exceed Health Canada's guideline. The province's geology includes uranium-bearing Precambrian rock in the north and glacial lake sediments — particularly the former bed of Lake Agassiz — that can concentrate radon-bearing soil gas. Winnipeg homes built over the clay-heavy Red River valley soil show variable but often elevated readings, and rural communities across Manitoba should also prioritize testing.

Typical Mitigation Cost in Manitoba

$1,800–$3,000

Near national average

Winnipeg is the primary market with competitive pricing; northern and rural communities may be slightly higher due to travel costs.

  • •Clay-heavy Winnipeg soil can affect sub-slab suction field size
  • •Foundation type — older Winnipeg homes often have block or rubble foundations
  • •Basement finish and pipe routing complexity
  • •Rural vs. Winnipeg contractor availability
  • •Sump pit configuration — a common radon entry point in Manitoba homes

Frequently Asked Questions: Radon in Manitoba

Winnipeg sits on former Lake Agassiz lakebed — deep clay deposits that can trap and channel soil gas. The city also has many older homes with block or rubble foundations that have numerous natural gaps. Cold winters seal homes for months at a time, accelerating radon accumulation.
Health Canada estimates roughly 10–15% of Manitoba homes exceed the 200 Bq/m³ guideline, though some Winnipeg surveys have found higher rates in specific neighbourhoods. Every home should be tested regardless of age or location.
Radon testing is not legally required in Manitoba real estate transactions. However, some Winnipeg realtors and home inspectors now recommend it as a standard part of due diligence, particularly for older homes.
Older Winnipeg homes — particularly those built before 1990 with block foundations, open sump pits, or unfinished basements — tend to have more radon entry points. Testing is especially important for these properties.
Manitoba follows the national guideline of 200 Bq/m³. Health Canada recommends mitigation if your home tests above this level.
DIY radon mitigation is not recommended. Proper system design requires understanding your home's sub-slab conditions, and incorrect installation can fail to reduce radon or even increase it. Always use a certified professional.
Use the city search above to find certified radon professionals in Winnipeg and across Manitoba. All listed professionals hold current C-NRPP certification.
Typical costs in Manitoba range from $1,800 to $3,000. Homes with complicated foundation types or multiple entry points may be at the higher end of this range.
