Radon IN YOUR HOME
Radon is a colourless, odourless gas that is produced from the natural breakdown of uranium in rocks and soil. Radon can enter a home through tiny openings in floors and foundations and build up to dangerous levels. Long-term exposure to radon is the second leading cause of lung cancer in Canada.
Based on the Health Canada survey, over one-third of health regions in Ontario had over 10% of homes which reported high radon levels. Even though these results vary across Ontario, it is important that all homes be tested for radon across the province.

Health Canada recommends that Canadians choose a certified radon professional from an accredited organization. The most effective radon reduction strategy is known as Active Soil Depressurization (ASD) which is typically performed by a contractor. It involves drilling a hole in the basement floor and a pipe is installed with a fan that draws the radon gas from under the house and vents it outside.
