Little of the land around Saint-Raymond has burned: 0% within 25 km since 1986, or 0.001% a year. Earthquakes add more: NRCan’s model puts building losses at $0.092 a year per $1,000 of value, against $0.030 for the typical town. Radon around Saint-Raymond is ordinary for Canada: 8.8% of tested homes over the guideline (6.6% typical). Hazard risk gives Saint-Raymond a grade of C, from earthquakes and radon alone.
What stands out about Saint-Raymond’s hazards
Four national sources, each read for Saint-Raymond: earthquakes, radon, past fires and flood studies.

Each hazard against its own yardstick; meters run from low to high on that yardstick.

Saint-Raymond grades C for hazard risk
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Saint-Raymond with little fire nearby would get no credit for it.
Its place: #141 of 507 in Quebec and #2,085 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.

A flood study covers Saint-Raymond, from Gouvernement du Québec: 1 on the inventory
What Canada’s Flood Map Inventory lists for Saint-Raymond: who studied flooding and where to see their maps.
For Saint-Raymond the inventory points to Gouvernement du Québec’s 2004 study, whose map is the one to check.

Towns with a flood study on file
Saint-Raymond is one of the 45% of towns in Quebec with a flood study on file, fewer than Canada’s 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-Raymond 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.”

Earthquakes cost buildings in Saint-Raymond $0.092 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
The typical town loses $0.030 a year to shaking; Saint-Raymond loses $0.092, 3.1 times as much.
Shaking damage a year per $1,000 of building value
Saint-Raymond’s $0.092 sits under the median in Quebec, $0.14, and well under La Pocatière’s $0.48.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
27% of Canada’s 2,611 towns expect more shaking damage than Saint-Raymond, which places it in the upper third.
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).
The model counts damage to Saint-Raymond’s buildings and their occupants from shaking only: not liquefaction, landslides, tsunami or fires after a quake.

Get ready for what Saint-Raymond faces
What to do about the hazards Saint-Raymond 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?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Saint-Raymond.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Saint-Raymond’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Saint-Raymond’s figure is its subdivision’s.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Saint-Raymond is its health region’s, the survey’s design unit.
Questions about flooding and hazards in Saint-Raymond
Does Saint-Raymond flood?
There is flood mapping for Saint-Raymond on the national inventory, each study linked to its owner’s map, none of them graded.
Is radon a problem in Saint-Raymond?

How is Saint-Raymond’s Hazard risk Grade worked out?
Saint-Raymond grades C for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
Is Saint-Raymond at risk of wildfire?
Fire has reached 0% of the land around Saint-Raymond since 1986 (last in 2009); at low, it neither helps nor hurts the grade.
How big is the earthquake risk in Saint-Raymond?
NRCan’s model expects shaking to cost buildings in Saint-Raymond $0.092 a year for every $1,000 of their value, on average over many years.
