Earthquake risk in Communauté de Wemotaci is ordinary: NRCan’s model puts building losses at $0.021 a year per $1,000 of value, close to the typical town’s $0.030. Radon is lower than usual: 0% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Communauté de Wemotaci grades D− for hazard risk, with wildfire counted against it.

Hazard risk in Communauté de Wemotaci: D−
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Communauté de Wemotaci 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. Small fires and grass fires are largely missing from the national burned-area record.

No flood study is listed for Communauté de Wemotaci
Flood studies whose area touches Communauté de Wemotaci, from NRCan’s inventory, each linked to its owner.
NRCan’s inventory is silent on Communauté de Wemotaci, so any flood map would be the municipality’s own.
Towns with a flood study on file
Only 45% of towns in Quebec have a flood study, short of Canada’s 58%, and Communauté de Wemotaci is not among them.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping is shown for Communauté de Wemotaci to be opened and checked, never turned into a grade.
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 Communauté de Wemotaci faces
What to do about the hazards Communauté de Wemotaci faces, and what to ask before you buy.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- 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.
- Has it had a radon test?
- Ask the municipality for flood maps.
- How close is the forest edge?
- Are flood and wildfire insured?
What this data can and can’t tell you
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Communauté de Wemotaci’s figure is its subdivision’s.
- 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 Communauté de Wemotaci.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Communauté de Wemotaci takes its 2007 health region’s share.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Communauté de Wemotaci’s homes since 1986, a history of fire that may lower Risk but never raises it.
