Ontario Radon Map
Radon can be found everywhere on earth, released naturally from rocks, soil and water, and can seep into homes through cracks and gaps in your insulation.
No areas of Canada are radon free.
Left undetected, radon can accumulate to dangerously high levels within your home, and can lead to radon-associated lung cancer – although it could take years before health problems begin to be noticeable.
Yet, radon doesn’t have to go undetected. Invest in peace of mind: buy yourself a home and water testing kit today to make sure your family’s air and water are safe.
