Radon is a naturally occurring radioactive gas that forms when uranium in soil and rock breaks down. It’s invisible, odourless, and tasteless — so the only way to know your level is to test.
Long-term exposure to elevated radon levels increases the risk of lung cancer. In Canada, radon is the leading cause of lung cancer among non-smokers.
Radon moves up through the soil and enters homes through cracks in foundations, floor joints, sump pits, drains, and tiny openings around pipes or wiring.
Radon is not just a “granite area” problem. While granite can contain uranium, radon is produced by many different types of soil and rock found all across Canada. Elevated radon levels have been found in homes in every province, including areas without granite. The only way to know your home’s level is to test.
You can test using:
• Short-term tests (2–7 days) — quick snapshot
• Long-term tests (3+ months) — most accurate and recommended by Health Canada
Health Canada recommends taking action if your home’s radon level is 200 Bq/m³ or higher based on a long-term test.
Radon mitigation is the process of reducing radon levels in a home. The most common and effective method is an Active Soil Depressurization (ASD) system.
An ASD system uses a quiet fan and vent pipe to create suction beneath your foundation. This draws radon gas from the soil and safely vents it above the roofline before it can enter your home.
Yes. Properly installed systems typically reduce radon levels by 80–99%, often bringing homes well below Health Canada guidelines.
No. Modern radon fans are designed to be quiet. Most homeowners barely notice them.
Most systems are installed in one day, depending on the home’s size and foundation type.
