Best Radon Testing & Mitigation in Fitzroy Harbour

About Radon in Fitzroy Harbour, Ontario

Last updated: March 2026

Fitzroy Harbour is served by C-NRPP certified radon professionals listed on RadonFinder.ca. Ontario has widely varying radon risk depending on geography. The Ottawa Valley, eastern Ontario, and areas underlain by the Canadian Shield, including parts of Sudbury, Elliot Lake, and the Bancroft region, have elevated radon due to uranium-rich granite bedrock. Southern Ontario's clay and limestone geology generally produces lower levels, though local hotspots exist in any region. The 2024 Cross-Canada survey found about 13% of Ontario homes exceed the guideline.

Fitzroy Harbour follows Health Canada's national guideline of 200 Bq/m³. If your home tests above this level, Health Canada recommends taking action to reduce radon within two years for levels between 200 and 600 Bq/m³, and within one year if above 600 Bq/m³.

Yes. Health Canada recommends testing every home in Canada, regardless of age, construction type, or location. Radon levels vary from house to house and even neighbouring homes can have very different readings. A long-term test of at least 91 days during the heating season is the most reliable method.

The most common system is active sub-slab depressurization (ASD). A certified professional installs a pipe through your foundation slab connected to a fan that draws radon from beneath the home and vents it safely above the roofline. Installation typically takes one day.
