Photo: Veillg1 · CC0Wildfire low, radon 8.2%: how Saint-Liboire stands on hazards
The national fire record shows next to nothing around Saint-Liboire, 0% of the land within 25 km since 1986 (0.000% a year). Earthquakes add more: NRCan’s model puts building losses at $0.12 a year per $1,000 of value, against $0.030 for the typical town. Saint-Liboire grades C for hazard risk; wildfire is low here, so it earns no credit.

Hazard risk in Saint-Liboire: C
Two inputs always count for Saint-Liboire, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #138 of 507 in Quebec and #2,082 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.

The flood map inventory lists nothing for Saint-Liboire
What Canada’s Flood Map Inventory lists for Saint-Liboire: who studied flooding and where to see their maps.
An empty entry for Saint-Liboire on the inventory isn’t proof of safety; ask locally for flood maps.
Towns with a flood study on file
Only 45% of towns in Quebec have a flood study, short of Canada’s 58%, and Saint-Liboire is not among them.
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-Liboire’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.”

Get ready for what Saint-Liboire faces
What to do about the hazards Saint-Liboire 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. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Saint-Liboire’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Saint-Liboire, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Saint-Liboire floods.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Saint-Liboire sits in.
