Radon rough-in by province the national code, then a local decision
The National Building Code, for the new houses it covers, calls for a permeable layer under the slab, a sealed sump if there is one, and a pipe stub. That is a rough-in: a fan can be added later. It is not a measurement, and it is not a running system.
Quebec, Ontario, Alberta, British Columbia and the other provinces do not adopt the code on the same day or with the same exceptions. The permit for that address, that year, is what applied. A “radon ready” brochure does not give you Bq/m³. New homes. Passive or active.
The 4-day test is a first reading. The 91-day test covers the three-month minimum Health Canada asks for. Both are $59 before tax. Shipping, the return and the lab are included. Tax is extra. The PDF report goes out within 2 business days after the lab receives the detector.
Above 200 Bq/m³, mitigation starts with a quote. Gaz Radon is C-NRPP certified and ships kits across Canada. See the Canada test page.
