Fire has left almost no mark near Pointe-Calumet: 0% of the land within 25 km since 1986, 0.000% a year. Earthquakes add more: NRCan’s model puts building losses at $0.15 a year per $1,000 of value, against $0.030 for the typical town. Radon is higher than usual: 10% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Pointe-Calumet a grade of C−, from earthquakes and radon alone.
What stands out about Pointe-Calumet’s hazards
Four national sources, each read for Pointe-Calumet: earthquakes, radon, past fires and flood studies.

Hazard risk in Pointe-Calumet: C−
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Pointe-Calumet with little fire nearby would get no credit for it.
Its place: #423 of 507 in Quebec and #2,414 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 78 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.
Few fires near Pointe-Calumet: 0% within 5 km, 0% within 25 km
Past fire around Pointe-Calumet’s homes, from the national burned-area record, with the fuel within 5 km.
With 0.000% burned a year, Pointe-Calumet is among the many low-band places (the typical Canadian town 0.000%).
Nothing inside 5 km of Pointe-Calumet’s homes has burned since 1986, and the nearest scar is 5.9 km off.
Land that isn’t forest covers nearly all the ground around Pointe-Calumet: forest fuel is 2.3% within 5 km and 2.6% within 25 km.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).
Burn rate a year, towns in Quebec · highest of 513
Fire has taken almost none of the land around Pointe-Calumet, as for 144 of the 513 towns in Quebec; Mistissini tops the list at 0.31%.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Pointe-Calumet, at a rounded zero, is far from them.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Pointe-Calumet.
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 Pointe-Calumet faces
What to do about the hazards Pointe-Calumet 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?
- Check the address on the flood map.
- Are flood and wildfire insured?
- Is earthquake cover included?
What this data can and can’t tell you
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Pointe-Calumet’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Pointe-Calumet’s.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Pointe-Calumet takes its 2007 health region’s share.
- 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 Pointe-Calumet.

How big is the earthquake risk in Pointe-Calumet?

Is Pointe-Calumet at risk of wildfire?
Fire has reached 0% of the land around Pointe-Calumet since 1986 (last in 2025); at low, it neither helps nor hurts the grade.
Does Pointe-Calumet flood?

How is Pointe-Calumet’s Hazard risk Grade worked out?
Hazard risk gives Pointe-Calumet C−, weighing earthquakes and radon and counting wildfire only against it.
