Photo: Veillg1 · CC0Wildfire low, radon 8.2%: how Saint-Clet stands on hazards
Fire has left almost no mark near Saint-Clet: 0% of the land within 25 km since 1986, 0.001% a year. Earthquakes add more: NRCan’s model puts building losses at $0.18 a year per $1,000 of value, against $0.030 for the typical town. Saint-Clet grades C− for hazard risk; wildfire is low here, so it earns no credit.

Hazard risk in Saint-Clet: C−
Two inputs always count for Saint-Clet, 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. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Few fires near Saint-Clet: 0% within 5 km, 0% within 25 km

Flood studies don’t enter the grade; they are listed so you can open the official map for Saint-Clet.
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.”
High seismic risk in Saint-Clet: $0.18 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.18 per $1,000, Saint-Clet carries roughly 6 times the typical Canadian town’s earthquake risk ($0.030).
Shaking damage a year per $1,000 of building value
Above the middle in Quebec: Saint-Clet’s $0.18 against a median of $0.14, with La Pocatière highest at $0.48.

Get ready for what Saint-Clet faces
What to do about the hazards Saint-Clet 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
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Saint-Clet’s included.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Saint-Clet is its health region’s, the survey’s design unit.
- 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-Clet.
- 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-Clet.
