Wildfire barely registers for Crestview, at 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. Hazard risk gives Crestview a grade of B+, from earthquakes and radon alone.
What stands out about Crestview’s hazards
Four national sources, each read for Crestview: earthquakes, radon, past fires and flood studies.
What Crestview faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Crestview: B+
Two inputs always count for Crestview, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #10 of 185 in Manitoba and #940 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The radon share rests on 66 home tests in the survey area, so a few homes move it. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Crestview has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Crestview’s residents live, and the fuel next to their homes.
A burn rate of 0.000% a year keeps Crestview in the low band (the typical Canadian town: 0.000%).
Around Crestview the forest is thin or far off: 0% of the land within 5 km and 0% within 25 km is forest fuel.
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 Manitoba · highest of 189
Of the 189 towns in Manitoba, 60 have a burn rate that rounds to zero, Crestview among them; Flin Flon (Part) leads at 1.68% a year.
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.
Measured against 2,610 towns, Crestview is in the largest group, low (92%), and at its floor, while 7.5% rank higher.
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 Crestview
Flood studies whose area touches Crestview, from NRCan’s inventory, each linked to its owner.
No flood study on the national inventory covers Crestview; ask the municipality, which is the authority for its flood maps.
Towns with a flood study on file
No study touches Crestview; in Manitoba, 18% of towns have one, below Canada’s 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of Crestview’s homes are at risk.
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.”
Little shaking expected in Crestview: $0.006 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
0.2 times the typical $0.030: Crestview’s $0.006 is low for Canada.
For earthquake risk, the only official count covers all of the city of Winnipeg, Crestview included.
Shaking damage a year per $1,000 of building value
Earthquake risk around Crestview ($0.006) matches the middle in Manitoba ($0.006), far from Virden’s $0.007.

Toward the quiet end of Canada’s range: 88% of its 2,611 towns sit above Crestview.
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 Crestview’s buildings and their occupants from shaking only: not liquefaction, landslides, tsunami or fires after a quake.

12% of homes tested around Crestview are over the radon guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Shared with the rest of the Winnipeg health region: radon tests
the typical Canadian town has 6.6% over the guideline; Crestview’s area has 12%.

The 10–20% band holds 22% of Canada’s 2,611 towns, Crestview among them; 4.6% rank above.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
A survey sample isn’t a map: any home in Crestview can be high, and a three-month test is the only way to know.

Get ready for what Crestview faces
What to do about the hazards Crestview 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. Wildfire is read from the national burned-area record around Crestview’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Crestview 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 Crestview until then.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Crestview’s figure is its subdivision’s.
