Fire seldom reaches Sainte-Eulalie: since 1986, 0% of the land within 25 km has burned (0.001% a year). Shaking is a bigger worry than in most places, at $0.12 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Sainte-Eulalie a grade of B+; its wildfire band pulls it down.
What stands out about Sainte-Eulalie’s hazards
For Sainte-Eulalie, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Sainte-Eulalie faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Sainte-Eulalie: B+
Earthquake risk and radon make Sainte-Eulalie’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 58 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.
Little of the land around Sainte-Eulalie has burned: 0.1% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Sainte-Eulalie’s residents live, and the fuel next to their homes.
Next to the typical Canadian town (0.000% a year), Sainte-Eulalie’s 0.001% is in the low band.
About as much forest grows next to Sainte-Eulalie’s homes (16% within 5 km) as across 25 km (16%).

Burn rate a year, towns in Quebec · highest of 514
Sainte-Eulalie burns at 0.001% a year, 136th of 514 towns in Quebec; the leader, Mistissini, reaches 0.31%.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
Low, like 92% of the country’s 2,610 towns: the land around Sainte-Eulalie burns, but slower than in the 7.5% above it.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

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. For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.”
Shaking is Sainte-Eulalie’s costliest hazard: $0.12 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Sainte-Eulalie’s $0.12 is about 4.1 times the typical town’s $0.030: it sits in one of Canada’s more active seismic zones.
Shaking damage a year per $1,000 of building value
Earthquake risk around Sainte-Eulalie ($0.12) matches the middle in Quebec ($0.14), far from La Pocatière’s $0.48.

Practical steps for Sainte-Eulalie’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. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Sainte-Eulalie’s included.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Sainte-Eulalie 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-Eulalie.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Sainte-Eulalie.
Questions about flooding and hazards in Sainte-Eulalie
How is Sainte-Eulalie’s Hazard risk Grade worked out?
Sainte-Eulalie grades B+ for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
Does Sainte-Eulalie flood?
No study on Canada’s Flood Map Inventory covers Sainte-Eulalie (0), which doesn’t mean it has never been mapped, so ask the municipality.
Is Sainte-Eulalie at risk of wildfire?
Not much by Canadian standards: Sainte-Eulalie’s band is low, with 0% of the land within 25 km burned since 1986 (last in 2020), so wildfire doesn’t change its grade.
How big is the earthquake risk in Sainte-Eulalie?
About $0.12 a year per $1,000 of building value, NRCan’s long-run expectation for Sainte-Eulalie.
Is radon a problem in Sainte-Eulalie?
0% of the 58 homes Health Canada tested around Sainte-Eulalie topped the guideline; your own house needs its own test.
