Winnipeg Radon Risk Map
Check the general radon risk for your area — then test to know for sure. Winnipeg sits in a known elevated-radon region, but every home is different.

Tap or click a zone to see its illustrative radon risk tier and what to do next. This is a general guide from local geology — not a reading for your specific home.
Illustrative geological risk — not a measurement of your home. Radon is invisible, has no smell, and varies between neighbouring houses. Testing is the only way to know your level.
What the numbers mean
Radon is measured in becquerels per cubic metre (Bq/m³). There's no truly "safe" level, but these are the reference lines that matter in Canada.
Why Winnipeg?
It comes down to what's under the ground — and how we heat our homes. Here's the plain version, no scare tactics.
The bedrock
Winnipeg sits on flat Prairie bedrock with elevated uranium. Manitoba has some of the highest radon levels in Canada — a large share of Winnipeg homes test above the 200 Bq/m³ guideline.
It gets into homes
Radon seeps up through basement cracks, sumps, and gaps around pipes. In our long, cold winters we seal homes tight — so it can build up to higher levels indoors.
Why it matters
Health Canada lists radon as the number one cause of lung cancer in people who don't smoke. The good news: it's measurable and fixable. You test, and if it's high, we fix it.
Regional context is based on Canadian geology and Health Canada guidance. It describes the area, not your house. Two homes on the same street can test very differently.
