Photo: Unknown Unknown · Public domainWildfire low, radon 13%: how Saint-Georges stands on hazards
Fire has left almost no mark near Saint-Georges: 0% of the land within 25 km since 1986, 0.000% a year. Seismic risk in Saint-Georges sits near the middle: $0.048 of expected damage per $1,000 of buildings a year, the typical town $0.030. Hazard risk gives Saint-Georges a grade of C−, from earthquakes and radon alone.
What stands out about Saint-Georges’s hazards
For Saint-Georges, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Saint-Georges faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Saint-Georges: C−
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Saint-Georges with little fire nearby would get no credit for it.
Its place: #333 of 507 in Quebec and #2,297 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Saint-Georges has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Saint-Georges’ residents live, and the fuel next to their homes.
At 0.000% of the land a year, Saint-Georges’ burn rate is in the low band; the typical Canadian town sees 0.000%.
Fire has stayed at least 20 km from Saint-Georges’ homes since 1986.
Forest fuel covers 54% of the land close to Saint-Georges and 60% across 25 km.

The low band holds 92% of Canada’s 2,610 towns, and Saint-Georges sits at its very bottom; only 7.5% are 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.

No flood study is listed for Saint-Georges
Flood studies whose area touches Saint-Georges, from NRCan’s inventory, each linked to its owner.
An empty entry for Saint-Georges 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-Georges.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of Saint-Georges’ homes stand in a flood zone.
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.”
Expected shaking damage in Saint-Georges: $0.048 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.
At $0.048 per $1,000, Saint-Georges’ earthquake risk is about the typical Canadian town’s ($0.030; 1.6 times).

Get ready for what Saint-Georges faces
What to do about the hazards Saint-Georges 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
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Saint-Georges is its health region’s, the survey’s design unit.
- 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 Saint-Georges.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Saint-Georges’ included.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Saint-Georges.
