Oakville radon testing and mitigation
213,800 residents. ~1 in 17 homes test above the Health Canada radon guideline.
Why Oakville homeowners test
Oakville's mix of older lakefront homes, newer builds in Joshua Creek and Bronte, and mid-century homes along the Trafalgar Road corridor creates a wide range of radon exposure. Newer homes with sealed foundations can trap radon even if soil-level gas is moderate.

Oakville-specific questions
Is radon a concern in Oakville specifically?
Moderate. Oakville's average radon levels are lower than Kingston or Thunder Bay but similar to the rest of the GTA. Individual homes can still test far above the average regardless of city-wide stats.
Do new Oakville builds need radon testing?
Yes. Newer homes are often more airtight, which can actually trap radon more effectively than older draftier homes. Many post-2010 Oakville builds in Joshua Creek, North Park, and the Trafalgar Road corridor have tested high despite being new.
Which Oakville neighbourhoods test highest on average?
Older Bronte and Lakeshore Road bungalows with stone or block foundations tend to top the list, alongside basement-finished mid-century homes near Sheridan College. Newer subdivisions can also surprise; we have seen 250+ Bq/m³ readings in 2018 to 2022 builds in West Oak Trails and Glen Abbey.
My Oakville home was built post-February 2021. Does Tarion cover radon mitigation?
Yes. If your home was purchased from a builder on or after Feb 1, 2021 and is within its 7-year Tarion warranty, the builder is required to fund radon mitigation up to $50,000 if a C-NRPP certified test reads at or above 200 Bq/m³. The new builds in Joshua Creek, Glenorchy, North Oakville, and the Dundas Trafalgar area are squarely in this window.
Do you service all of Oakville including Bronte and Glen Abbey?
Yes. Every Oakville neighbourhood including Bronte, Glen Abbey, West Oak Trails, Joshua Creek, College Park, River Oaks, Glenorchy, Lakeshore, and North Oakville. Same $99 testing price across all of Oakville, no distance surcharge.
About these numbers
Population and home counts come from Statistics Canada's 2021 Census of Population 1 . These are exact figures.
The per-city radon percentage is a synthesis estimate, not a number pulled directly from any single source. We blend three datasets: Health Canada's Cross-Canada Survey of Radon Concentrations in Homes (the 2012 federal baseline) 4 , the University of Calgary's Evict Radon citizen-science mapping project 2 , and Take Action on Radon's aggregated municipal data 5 .
The federal baseline often reports lower above-guideline rates than the newer citizen-science projects. Two reasons: the federal study is now 14+ years old, and the newer citizen-science projects sample more aggressively in homes built under tighter modern building codes (which trap soil gas more effectively than older draftier construction). Where these sources disagree on a specific municipality, our published percentage lands on a working midpoint. So if you click through to the federal survey expecting to find "Oakville 6%" verbatim, you won't. The federal survey may report a lower figure for the same area, and the citizen-science maps often report a higher one. We chose the midpoint because no single source is definitive.
None of this gives you a definitive percentage for your specific home. Two homes on the same street can test 30 Bq/m³ apart. The only reliable answer for your home is a test on that home.
