Best Radon Testing & Mitigation in Winnipeg

About Radon in Winnipeg, Manitoba

Last updated: March 2026

Winnipeg is served by C-NRPP certified radon professionals listed on RadonFinder.ca. 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.

Winnipeg follows Health Canada’s national guideline of 200 Bq/m³. If your home tests above this level, Health Canada recommends taking action to reduce radon — within two years for levels between 200 and 600 Bq/m³, and within one year if above 600 Bq/m³.
Yes. Health Canada recommends testing every home in Canada, regardless of age, construction type, or location. Radon levels vary from house to house — even neighbouring homes can have very different readings. A long-term test of at least 91 days during the heating season is the most reliable method.
