Fire seldom reaches Pincourt: since 1986, 0.1% of the land within 25 km has burned (0.001% a year). Shaking is a bigger worry than in most places, at $0.17 a year per $1,000 of building value ($0.030 typical). Radon around Pincourt is ordinary for Canada: 8.2% of tested homes over the guideline (6.6% typical). Pincourt grades C− for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Pincourt’s hazards
Four national sources, each read for Pincourt: earthquakes, radon, past fires and flood studies.
What Pincourt faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Pincourt: C−
The grade weighs Pincourt’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #291 of 507 in Quebec and #2,252 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near Pincourt: 0.1% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Pincourt’s homes, from the national burned-area record, with the fuel within 5 km.
Low: the land around Pincourt burns at 0.001% a year, where the typical Canadian town sees 0.000%.
The 5 km ring around Pincourt’s homes is clear of burns since 1986, the nearest 13 km out.
Forest makes up 1.4% of the land within 5 km of Pincourt and 2.4% within 25 km, little for a forest fire to run through.
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
Pincourt burns at 0.001% a year, 136th of 513 towns in Quebec; the leader, Mistissini, reaches 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.
The low band takes in 92% of Canada’s 2,610 towns, Pincourt among them, though its rate is above zero; 7.5% rank higher.
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.

Flooding around Pincourt is mapped in 2 studies, the newest by Communauté métropolitaine de Montréal
What Canada’s Flood Map Inventory lists for Pincourt: who studied flooding and where to see their maps.
For Pincourt the inventory points to 2 studies, most recently Communauté métropolitaine de Montréal’s in 2008.
| Study | By | Year | Status |

Towns with a flood study on file
Flood maps are thinner in Quebec, 45% of towns against 58% nationally, but Pincourt has one.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping around Pincourt has come in steps: 2 studies from the 1970s to the 2000s.
Study dates as the NRCan inventory lists them, one count per study touching Pincourt.
The grade leaves flood out, since a study area says nothing about how many of Pincourt’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.”

Shaking is Pincourt’s costliest hazard: $0.17 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
The typical town loses $0.030 a year to shaking; Pincourt loses $0.17, 5.6 times as much.
Shaking damage a year per $1,000 of building value
Earthquake risk around Pincourt ($0.17) matches the middle in Quebec ($0.14), far from La Pocatière’s $0.48.

Get ready for what Pincourt faces
What to do about the hazards Pincourt 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
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Pincourt’s figure is its subdivision’s.
- 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 Pincourt 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 Pincourt sits in.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Pincourt’s homes since 1986, a history of fire that may lower Risk but never raises it.
