Fire seldom reaches Daveluyville: since 1986, 0% of the land within 25 km has burned (0.001% a year). Earthquakes add more: NRCan’s model puts building losses at $0.14 a year per $1,000 of value, against $0.030 for the typical town. Daveluyville grades B+ for hazard risk, with wildfire counted against it.

What Daveluyville faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Daveluyville: B+
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Daveluyville with little fire nearby would get no credit for it.
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. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Daveluyville: 0% of the land within 25 km burned since 1986, 0.4% within 5 km
Fires mapped since 1986 around where Daveluyville’s residents live, and the fuel next to their homes.
Low: the land around Daveluyville burns at 0.001% a year, where the typical Canadian town sees 0.000%.
About as much forest grows next to Daveluyville’s homes (24% within 5 km) as across 25 km (25%).

No flood study is listed for Daveluyville
Flood studies whose area touches Daveluyville, from NRCan’s inventory, each linked to its owner.
NRCan’s inventory is silent on Daveluyville, so any flood map would be the municipality’s own.

Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Daveluyville.
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.”
Shaking is Daveluyville’s costliest hazard: $0.14 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 $0.14 per $1,000, Daveluyville carries roughly 4.6 times the typical Canadian town’s earthquake risk ($0.030).
Shaking damage a year per $1,000 of building value

0% of homes tested around Daveluyville are over the radon guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline.
A lower share than most: 0% of tested homes around Daveluyville, the typical Canadian town 6.6%. Daveluyville doesn’t get its own radon tests figures; the ones here come from the Mauricie et Centre-du-Quebec health region.

Get ready for what Daveluyville faces
What to do about the hazards Daveluyville 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 Daveluyville.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Daveluyville takes its 2007 health region’s share.
- 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 Daveluyville.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Daveluyville’s included.
