Little of the land around Stanley has burned: 0% within 25 km since 1986, or 0.001% a year. Shaking is less of a worry than in most places, at $0.004 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Stanley a grade of B, from earthquakes and radon alone.
What stands out about Stanley’s hazards
For Stanley, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Hazard risk in Stanley: B
The grade weighs Stanley’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #148 of 185 in Manitoba and #1,565 of 2,589 Canadian towns.
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 Stanley has burned: 0.1% within 5 km, 0% within 25 km since 1986
Past fire around Stanley’s homes, from the national burned-area record, with the fuel within 5 km.
At 0.001% of the land a year, Stanley’s burn rate is in the low band; the typical Canadian town sees 0.000%.
Little near Stanley’s homes can carry a forest fire; only 0% of the land within 5 km is forest fuel, and 0% within 25 km.

Burn rate a year, towns in Manitoba · highest of 189
Stanley ranks 31st of the 189 towns in Manitoba for burn rate, at 0.001% a year; Flin Flon (Part) leads with 1.68%.
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.
The low band takes in 92% of Canada’s 2,610 towns, Stanley among them, though its rate is above zero; 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.

No flood study is listed for Stanley
What Canada’s Flood Map Inventory lists for Stanley: who studied flooding and where to see their maps.
Canada’s Flood Map Inventory lists no study whose area touches Stanley, which doesn’t mean it has never been mapped.
Towns with a flood study on file
Mapping in Manitoba reaches 18% of towns, below the 58% across Canada, and not Stanley.
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 Stanley 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.”
Earthquakes cost buildings in Stanley just $0.004 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
0.1 times the typical $0.030: Stanley’s $0.004 is low for Canada.
Shaking damage a year per $1,000 of building value
The typical town in Manitoba expects $0.006 a year in shaking damage; Stanley expects less, $0.004, and Virden the most, $0.007.

Radon runs high around Stanley: 43% of tested homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
the typical Canadian town has 6.6% over the guideline; Stanley’s area has 43%. Stanley shares its radon tests numbers with the rest of the Central health region.

Radon runs higher around Stanley than in most towns in Manitoba: 43% over the guideline (12% is typical), 7.4% over 600.

No band is higher: Stanley is among the 1.5% of Canada’s towns with 30% or more of tests over 200 Bq/m³.
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.
Radon varies from house to house in Stanley, so the survey is a reason to test, not a result for yours.

Where to get warnings in Stanley
Alerts for Stanley come from Environment and Climate Change Canada and, for emergencies, Alert Ready.
| Alert | What it means |
|---|---|
| Warning | Severe weather is happening or about to: act now. |
| Watch | Conditions favour severe weather: be ready. |
| Advisory | Weather that is less severe but could disrupt the day. |
| Special weather statement | Unusual weather worth knowing about. |
| Special air quality statement | Poor air, often wildfire smoke. |
Alert Ready carries evacuation orders for Stanley to phones; CWFIS shows the day’s fire danger.

Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Stanley faces
What to do about the hazards Stanley 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
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Stanley’s census subdivision (a neighbourhood shows its city’s).
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Stanley takes its 2007 health region’s share.
- Wildfire counts one way. For Stanley, 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. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Stanley.
Questions about flooding and hazards in Stanley
How is Stanley’s Hazard risk Grade worked out?
Stanley grades B for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
Is Stanley at risk of wildfire?
Fire has reached 0% of the land around Stanley since 1986 (last in 2000); at low, it neither helps nor hurts the grade.
Is radon a problem in Stanley?
Around Stanley, 108 survey homes were tested and 43% came in over 200 Bq/m³, a guide to the area, not to any one home.
How big is the earthquake risk in Stanley?
NRCan’s model expects shaking to cost buildings in Stanley $0.004 a year for every $1,000 of their value, on average over many years.
Does Stanley flood?
With 0 studies on the inventory, Stanley’s flood risk is unmapped nationally; check with the municipality before buying.
