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.
