Leger faces fewer hazards than 98% of Canadian towns
Wildfire barely registers for Leger, at 0% of the land within 25 km since 1986 (0.000% a year). Earthquakes matter little: NRCan’s model puts building losses at $0.013 a year per $1,000 of value, against $0.030 for the typical town. In Health Canada’s survey, just 1.4% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Hazard risk gives Leger a grade of A+; its wildfire band pulls it down.
What stands out about Leger’s hazards
Four national sources, each read for Leger: earthquakes, radon, past fires and flood studies.
What Leger faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Leger grades A+ for hazard risk
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Leger with little fire nearby would get no credit for it.
Its place: #11 of 474 in Alberta and #22 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The radon share rests on 73 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 Leger has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Leger’s residents live, and the fuel next to their homes.
Forty years of fire maps put Leger at 0.000% a year, low next to the typical Canadian town’s 0.000%.
No fire has burned within 5 km of Leger’s homes since 1986; the nearest burn is 20 km away.
Forest makes up 1.5% of the land within 5 km of Leger and 0.5% within 25 km, little for a forest fire to run through.

Burn rate a year, towns in Alberta · highest of 478
Little or nothing burns around Leger in a typical year; 386 of the 478 towns in Alberta share that, and Wainwright leads at 1.43%.
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, Leger 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.

No flood study is listed for Leger
Flood studies whose area touches Leger, from NRCan’s inventory, each linked to its owner.
Nationally, Leger has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Only 46% of towns in Alberta have a flood study, short of Canada’s 58%, and Leger is not among them.
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 Leger 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 Leger just $0.013 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
0.4 times the typical $0.030: Leger’s $0.013 is low for Canada.
Leger doesn’t get its own earthquake risk figures; the ones here come from the city of Edmonton.
Shaking damage a year per $1,000 of building value

Radon runs low around Leger: 1.4% of tested homes over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Measured across the Capital Health: radon tests
Radon runs below the typical Canadian town (6.6%) in Leger’s area, at 1.4%.

Radon rarely tops the guideline around Leger, as for 37% of Canada’s 2,611 towns; 63% see more.
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.
One home in Leger can be high while next door is low; a three-month test settles it.

Get ready for what Leger faces
What to do about the hazards Leger 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
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Leger takes its 2007 health region’s share.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Leger’s.
- 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 Leger.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Leger’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
