Wildfire isn’t Saint-Rémi’s worry: 0% of the land within 25 km burned since 1986 (0.001% a year). Seismic risk runs high: $0.18 of expected damage per $1,000 of buildings a year, the typical town $0.030. Radon around Saint-Rémi is ordinary for Canada: 8.2% of tested homes over the guideline (6.6% typical). Saint-Rémi grades C− for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Saint-Rémi’s hazards
For Saint-Rémi, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Saint-Rémi faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Saint-Rémi grades C− for hazard risk
Earthquake risk and radon make Saint-Rémi’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #330 of 507 in Quebec and #2,292 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Saint-Rémi: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Saint-Rémi’s homes, from the national burned-area record, with the fuel within 5 km.
At 0.001% of the land a year, Saint-Rémi’s burn rate is in the low band; the typical Canadian town sees 0.000%.
No fire has burned within 5 km of Saint-Rémi’s homes since 1986; the nearest burn is 9.5 km away.
Little near Saint-Rémi’s homes can carry a forest fire; only 0.6% of the land within 5 km is forest fuel, and 3.4% 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
At 0.001% a year, Saint-Rémi ranks 136th of the 513 towns in Quebec; Mistissini leads 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.
7.5% of Canada’s 2,610 towns burn fast enough to rank moderate or above; Saint-Rémi stays low, with 92%.
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.

Towns with a flood study on file
Its flood study sets Saint-Rémi apart in Quebec, where 45% of towns have one (Canada: 58%).
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Listed, not scored: a flood study proves a map exists, not that Saint-Rémi floods.
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.”

High seismic risk in Saint-Rémi: $0.18 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Roughly 6 times the typical $0.030: Saint-Rémi’s $0.18 marks real seismic exposure.
Shaking damage a year per $1,000 of building value
Earthquake risk in Quebec peaks in La Pocatière ($0.48); Saint-Rémi, at $0.18, sits above the median of $0.14.

In the upper part of Canada’s range: 14% of its 2,611 towns expect more damage than Saint-Rémi.

Get ready for what Saint-Rémi faces
Practical steps for Saint-Rémi’s hazards, most pressing first.
- 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
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Saint-Rémi without grading them.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Saint-Rémi’s included.
- 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 Saint-Rémi.
- Radon is a survey. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around Saint-Rémi until then.
Questions about flooding and hazards in Saint-Rémi
Is Saint-Rémi at risk of wildfire?
Some, but Saint-Rémi’s low band (0% of nearby land burned since 1986, latest 2025) is short of the level that counts.
Does Saint-Rémi flood?
A flood study covers Saint-Rémi on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
Is radon a problem in Saint-Rémi?
The area’s survey found 8.2% of 110 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Saint-Rémi.
How big is the earthquake risk in Saint-Rémi?
In NRCan’s seismic model, Saint-Rémi’s buildings lose $0.18 per $1,000 of value in an average year.
How is Saint-Rémi’s Hazard risk Grade worked out?
Hazard risk gives Saint-Rémi C−, weighing earthquakes and radon and counting wildfire only against it.
