Little of the land around Sainte-Anne-des-Plaines has burned: 0% within 25 km since 1986, or 0.001% a year. Earthquakes add more: NRCan’s model puts building losses at $0.19 a year per $1,000 of value, against $0.030 for the typical town. Radon is higher than usual: 10% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Sainte-Anne-des-Plaines a grade of D, from earthquakes and radon alone.

Sainte-Anne-des-Plaines grades D for hazard risk
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Sainte-Anne-des-Plaines with little fire nearby would get no credit for it.
Its place: #445 of 507 in Quebec and #2,440 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The radon share rests on 78 home tests in the survey area, so a few homes move it. The burned-area record misses fires under about 10 ha and most grass and farm fires.

Canada’s Flood Map Inventory lists no study whose area touches Sainte-Anne-des-Plaines, which doesn’t mean it has never been mapped.

The inventory’s own caution (NRCan): “The Canada Flood Map (CFM) does not include every flood hazard map in Canada and may be incomplete or contain inaccuracies. It should not be relied upon as the official source of flood mapping information. Furthermore, if a map appears to be missing, this does not necessarily mean that the area has never been mapped.

Get ready for what Sainte-Anne-des-Plaines faces
What to do about the hazards Sainte-Anne-des-Plaines 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.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
- Is earthquake cover included?
What this data can and can’t tell you
- 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 Sainte-Anne-des-Plaines floods.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Sainte-Anne-des-Plaines’ census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Sainte-Anne-des-Plaines, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- 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 Sainte-Anne-des-Plaines sits in.
