Since 1986 almost nothing has burned near Saint-Eugène: 0% of the land within 25 km, or 0.000% 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). Saint-Eugène grades B+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Saint-Eugène’s hazards
Four national sources, each read for Saint-Eugène: earthquakes, radon, past fires and flood studies.
What Saint-Eugène faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Saint-Eugène grades B+ for hazard risk
Two inputs always count for Saint-Eugène, earthquakes and radon; the third, wildfire, counts only against a town.
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. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near Saint-Eugène: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Saint-Eugène’s residents live, and the fuel next to their homes.
The yearly burn rate around Saint-Eugène is 0.000%, low beside 0.000% for the typical Canadian town.
Saint-Eugène’s homes have had no fire within 5 km since 1986; the closest was 14 km away.
About as much forest grows next to Saint-Eugène’s homes (7.1% within 5 km) as across 25 km (6.2%).

Burn rate a year, towns in Quebec · highest of 514
Near-zero burning puts Saint-Eugène with 145 of the 514 towns in Quebec, far below Mistissini at 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.
Most of the country’s 2,610 towns are low-band (92%, against 7.5% above); around Saint-Eugène, burning rounds to zero.
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.

No flood study is listed for Saint-Eugène
Flood studies whose area touches Saint-Eugène, from NRCan’s inventory, each linked to its owner.
An empty entry for Saint-Eugène on the inventory isn’t proof of safety; ask locally for flood maps.
Towns with a flood study on file
Mapping in Quebec reaches 45% of towns, below the 58% across Canada, and not Saint-Eugène.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of Saint-Eugène’s homes are at risk.
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.”
Earthquakes cost buildings in Saint-Eugène $0.12 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
The typical town loses $0.030 a year to shaking; Saint-Eugène loses $0.12, 3.9 times as much.
Shaking damage a year per $1,000 of building value
Earthquake risk around Saint-Eugène ($0.12) matches the middle in Quebec ($0.14), far from La Pocatière’s $0.48.

In the upper part of Canada’s range: 24% of its 2,611 towns expect more damage than Saint-Eugène.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
The loss is to Saint-Eugène’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Get ready for what Saint-Eugène faces
What to do about the hazards Saint-Eugène 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. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Saint-Eugène.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Saint-Eugène’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, Saint-Eugène takes its 2007 health region’s share.
- 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 Saint-Eugène’s.
