Wildfire barely registers for Banff Trail, at 0% of the land within 25 km since 1986 (0.000% a year). Shaking is about as much of a worry in Banff Trail as in most places, at $0.023 a year per $1,000 of building value ($0.030 typical). Banff Trail’s survey area, 8.1% over the radon guideline, is close to the typical town’s 6.6%. Banff Trail grades B+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Banff Trail’s hazards
Four national sources, each read for Banff Trail: earthquakes, radon, past fires and flood studies.

Banff Trail grades B+ for hazard risk
Earthquake risk and radon make Banff Trail’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near Banff Trail: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Banff Trail’s residents live, and the fuel next to their homes.
Low by Canadian standards: 0.000% of the land a year around Banff Trail, 0.000% for the typical Canadian town.
Nothing inside 5 km of Banff Trail’s homes has burned since 1986, and the nearest scar is 6.9 km off.
With 0% forest fuel within 5 km and 1.1% within 25 km, the land around Banff Trail gives a fire little to burn.

Burn rate a year, towns in Alberta · highest of 478
To three decimals the burn rate around Banff Trail is zero, as for 386 of the 478 towns in Alberta, while Wainwright reaches 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.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Banff Trail, at a rounded zero, is far from them.
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.

Towns with a flood study on file
Banff Trail is one of the 46% of towns in Alberta with a flood study on file, fewer than Canada’s 58%.
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 Banff Trail 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.”

Expected shaking damage in Banff Trail: $0.023 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.
At $0.023 per $1,000, Banff Trail’s earthquake risk is about the typical Canadian town’s ($0.030; 0.8 times).
Behind earthquake risk sits data gathered across the city of Calgary, with Banff Trail one part of it.
Shaking damage a year per $1,000 of building value
Banff Trail’s $0.023 tops the median in Alberta, $0.013, though Black Diamond reaches $0.048.

Banff Trail sits mid-range among Canada’s 2,611 towns: 54% expect more shaking damage.
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 loss is to Banff Trail’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Get ready for what Banff Trail faces
Practical steps for Banff Trail’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. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Banff Trail’s.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Banff Trail’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Banff Trail is its health region’s, the survey’s design unit.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Banff Trail.
Questions about flooding and hazards in Banff Trail
How is Banff Trail’s Hazard risk Grade worked out?
Banff Trail’s Hazard risk grade is B+, built on earthquakes and radon with a one-sided wildfire input.
How big is the earthquake risk in Banff Trail?
