Little of the land around Entrelacs has burned: 0.1% within 25 km since 1986, or 0.001% a year. Shaking is a bigger worry than in most places, at $0.060 a year per $1,000 of building value ($0.030 typical). Entrelacs grades B+ for hazard risk, with wildfire counted against it.
What stands out about Entrelacs’s hazards
For Entrelacs, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Entrelacs grades B+ for hazard risk
Two inputs always count for Entrelacs, earthquakes and radon; the third, wildfire, counts only against a town.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The radon share rests on 77 home tests in the survey area, so a few homes move it. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Few fires near Entrelacs: 0% within 5 km, 0.1% within 25 km
Fires mapped since 1986 around where Entrelacs’ residents live, and the fuel next to their homes.

The flood map inventory lists nothing for Entrelacs
Flood studies whose area touches Entrelacs, from NRCan’s inventory, each linked to its owner.
Canada’s Flood Map Inventory lists no study whose area touches Entrelacs, which doesn’t mean it has never been mapped.
Towns with a flood study on file
No study touches Entrelacs; in Quebec, 45% of towns have one, below Canada’s 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood studies don’t enter the grade; they are listed so you can open the official map for Entrelacs.
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 Entrelacs $0.060 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.
At $0.060 per $1,000, Entrelacs carries roughly 2 times the typical Canadian town’s earthquake risk ($0.030).

Get ready for what Entrelacs faces
What to do about the hazards Entrelacs 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
- 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 Entrelacs floods.
- 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 Entrelacs.
- 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 Entrelacs sits in.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Entrelacs’ included.
