Wildfire barely registers for Saint-Siméon, at 0% of the land within 25 km since 1986 (0.000% a year). NRCan expects $0.033 of shaking damage a year per $1,000 of buildings in Saint-Siméon, near the typical $0.030. Hazard risk gives Saint-Siméon a grade of C−, from earthquakes and radon alone.
What stands out about Saint-Siméon’s hazards
For Saint-Siméon, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Saint-Siméon faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Saint-Siméon: C−
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Saint-Siméon 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. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Saint-Siméon has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Saint-Siméon’s homes, from the national burned-area record, with the fuel within 5 km.
Low: the land around Saint-Siméon burns at 0.000% a year, where the typical Canadian town sees 0.000%.
Nothing inside 5 km of Saint-Siméon’s homes has burned since 1986, and the nearest scar is 21 km off.
Forest thickens with distance from Saint-Siméon: 74% of the land within 5 km, 84% 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).

No flood study is listed for Saint-Siméon
What Canada’s Flood Map Inventory lists for Saint-Siméon: who studied flooding and where to see their maps.
The inventory has nothing for Saint-Siméon, but a local or conservation-authority map may still exist.
Towns with a flood study on file
Saint-Siméon has no flood study on file; only 45% of towns in Quebec do, against 58% across Canada.
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 Saint-Siméon 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.”
Expected shaking damage in Saint-Siméon: $0.033 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Saint-Siméon’s $0.033 is close to the typical town’s $0.030 (1.1 times as much).
Shaking damage a year per $1,000 of building value
Earthquake risk in Quebec peaks in La Pocatière ($0.48); Saint-Siméon, at $0.033, is below the median of $0.14.

Middle of the pack: 48% of Canada’s 2,611 towns have more earthquake risk than Saint-Siméon.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
Only shaking damage to buildings in Saint-Siméon is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Saint-Siméon faces
What to do about the hazards Saint-Siméon 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.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- 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-Siméon.
- 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 Saint-Siméon.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Saint-Siméon takes its 2007 health region’s share.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Saint-Siméon’s included.
