The national fire record shows next to nothing around Redvers, 0% of the land within 25 km since 1986 (0.000% a year). Earthquakes matter little: NRCan’s model puts building losses at $0.006 a year per $1,000 of value, against $0.030 for the typical town. Redvers grades B for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Redvers’s hazards
For Redvers, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Redvers faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Redvers: B
Two inputs always count for Redvers, earthquakes and radon; the third, wildfire, counts only against a town.
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 Redvers: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Redvers’ homes, from the national burned-area record, with the fuel within 5 km.
Low: the land around Redvers burns at 0.000% a year, where the typical Canadian town sees 0.000%.
Forest fuel is scarce around Redvers: 0% of the land within 5 km, 0% within 25 km.

Burn rate a year, towns in Saskatchewan · highest of 105
Among the 105 towns in Saskatchewan, La Loche burns fastest (1.94% a year); Redvers is with the 55 near zero.
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.
92% of Canada’s 2,610 towns are in the low band and 7.5% above it; Redvers is among the many where the yearly burn rate rounds to zero.
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.

The flood map inventory lists nothing for Redvers
What Canada’s Flood Map Inventory lists for Redvers: who studied flooding and where to see their maps.
Nationally, Redvers has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Mapping in Saskatchewan reaches 55% of towns, below the 58% across Canada, and not Redvers.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of Redvers’ homes stand in a flood zone.
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.”
Low seismic risk in Redvers: $0.006 per $1,000 of buildings a year

Get ready for what Redvers faces
What to do about the hazards Redvers 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. For Redvers, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Redvers without grading them.
- 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 Redvers until then.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Redvers’ census subdivision (a neighbourhood shows its city’s).
