Hazard risk in Saint-Bruno-de-Guigues: A−
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Saint-Bruno-de-Guigues with little fire nearby would get no credit for it.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 69 homes were tested in the survey area, so the radon share is rough. The burned-area record misses fires under about 10 ha and most grass and farm fires.

Get ready for what Saint-Bruno-de-Guigues faces
What to do about the hazards Saint-Bruno-de-Guigues faces, and what to ask before you buy.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.
- Move papers and medicines upstairs.
- Ask whether your street is mapped.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. For Saint-Bruno-de-Guigues, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Saint-Bruno-de-Guigues’ census subdivision (a neighbourhood shows its city’s).
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Saint-Bruno-de-Guigues floods.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Saint-Bruno-de-Guigues sits in.
