Radon by province the 2012 survey, raw percentages side by side
From long-term tests done in the winters of 2009–2011, Health Canada estimated that 6.9% of Canadians lived in a home above 200 Bq/m³. That is not “one home in five” in every city, and it is not a pass for the provinces that sit lower. The same report says no region of the country is without radon.
The raw percentage counts the homes that were actually tested. The weighted percentage brings the result closer to the weight of the population. Both appear below. A house in Brandon and a house in Toronto do not share the Canadian figure.
Where the survey rises
The highest raw percentages: New Brunswick 24.8%, Manitoba 23.7%, Yukon 19.6%, Saskatchewan 16.3%. Inside those provinces, some health regions go higher still. Brandon: 44.3% of 79 homes. New Brunswick health region 6: 40.0% of 115 homes. Parkland, in Manitoba: 43.4%.
Where a provincial average hides a sector
Ontario’s weighted figure is 4.6%, but Leeds, Grenville and Lanark is at 19.4%, and Toronto at 2.7%. British Columbia’s weighted figure is 3.9%, Vancouver 1.2%, and Kootenay-Boundary (Castlegar, Trail) 29.3%. In Quebec, Gaspésie–Îles-de-la-Madeleine is at 25.3% of 174 homes, while the province’s raw average is 10.1%.

The 4-day test gives a first reading. The 91-day test covers the three-month minimum Health Canada asks for. Both are $59 before tax: shipping, return and the laboratory are included, taxes extra. The PDF report is sent within 2 business days after the laboratory receives the detector.
Above 200 Bq/m³, mitigation is confirmed with a quote. Gaz Radon is C-NRPP certified for measurement and mitigation.
