Sainte-Anne-de-Beaupré grades C for hazard risk
For Sainte-Anne-de-Beaupré, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
Its place: #274 of 507 in Quebec and #2,227 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.

Get ready for what Sainte-Anne-de-Beaupré faces
Practical steps for Sainte-Anne-de-Beaupré’s hazards, most pressing first.
- 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
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Sainte-Anne-de-Beaupré’s.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Sainte-Anne-de-Beaupré’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Sainte-Anne-de-Beaupré takes its 2007 health region’s share.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Sainte-Anne-de-Beaupré.
