Burn scars are few around De Salaberry, with 0.7% of the land within 25 km touched by fire since 1986 (0.02% a year). Seismic risk runs low: $0.005 of expected damage per $1,000 of buildings a year, the typical town $0.030. Radon around De Salaberry is ordinary for Canada: 9.7% of tested homes over the guideline (6.6% typical). Hazard risk gives De Salaberry a grade of A−; its wildfire band pulls it down.
What stands out about De Salaberry’s hazards
Four national sources, each read for De Salaberry: earthquakes, radon, past fires and flood studies.
What De Salaberry faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Earthquakes

Flood study
De Salaberry grades A− for hazard risk
Earthquake risk and radon make De Salaberry’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #1 of 185 in Manitoba and #635 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 De Salaberry: 0.7% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where De Salaberry’s residents live, and the fuel next to their homes.
In a typical year 0.02% of the land near De Salaberry burns; the typical Canadian town sees 0.000%, and both are low.
Nothing inside 5 km of De Salaberry’s homes has burned since 1986, and the nearest scar is 8.8 km off.
With 0% forest fuel within 5 km and 0.1% within 25 km, the land around De Salaberry gives a fire little to burn.
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).

Flood studies don’t enter the grade; they are listed so you can open the official map for De Salaberry.
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.

Get ready for what De Salaberry faces
Practical steps for De Salaberry’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.
- 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
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; De Salaberry’s figure is its subdivision’s.
- 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 De Salaberry until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for De Salaberry without grading them.
- Wildfire counts one way. Wildfire is read from the national burned-area record around De Salaberry’s homes since 1986, a history of fire that may lower Risk but never raises it.
