For Leduc, wildfire history is close to nil: 0% of nearby land since 1986, 0.000% a year. Seismic risk runs low: $0.015 of expected damage per $1,000 of buildings a year, the typical town $0.030. Fewer homes than usual carry radon here, 1.4% over the guideline where the typical town has 6.6%. Leduc grades A+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Leduc’s hazards
For Leduc, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Hazard risk in Leduc: A+
Seismic risk and radon set Leduc’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #209 of 474 in Alberta and #231 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 73 homes were tested in the survey area, so the radon share is rough. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Leduc: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Leduc’s homes, from the national burned-area record, with the fuel within 5 km.
Around Leduc fire takes 0.000% of the land in a typical year, the typical Canadian town 0.000%, which is low.
The 5 km ring around Leduc’s homes is clear of burns since 1986, the nearest 17 km out.
Forest fuel is scarce around Leduc: 0% of the land within 5 km, 0.5% within 25 km.
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 Alberta · highest of 478
Wainwright has the highest burn rate in Alberta, 1.43% a year; around Leduc, as around 386 of the 478 towns, it rounds to 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.
Like most of Canada’s 2,610 towns (92%), Leduc is in the low band, with a burn rate of zero to three decimals; 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 Leduc

There is no study for Leduc on the national flood inventory, which is far from complete.
Towns with a flood study on file
No study touches Leduc; in Alberta, 46% of towns have one, below Canada’s 58%.

Flood mapping is shown for Leduc 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.”
Little shaking expected in Leduc: $0.015 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Shaking costs the typical town $0.030 a year; in Leduc it is only $0.015, 0.5 times as much.

Little radon around Leduc: 1.4% of area homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Where the typical Canadian town has 6.6% of homes over the guideline, Leduc’s area has fewer, 1.4%. Leduc doesn’t get its own radon tests figures; the ones here come from the Capital Health.

Get ready for what Leduc faces
Practical steps for Leduc’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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Leduc is its health region’s, the survey’s design unit.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Leduc’s included.
- 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 Leduc.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Leduc.
Questions about flooding and hazards in Leduc
How big is the earthquake risk in Leduc?
NRCan’s model expects shaking to cost buildings in Leduc $0.015 a year for every $1,000 of their value, on average over many years.
Is radon a problem in Leduc?
The area’s survey found 1.4% of 73 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Leduc.
How is Leduc’s Hazard risk Grade worked out?
Leduc’s Hazard risk grade is A+, built on earthquakes and radon with a one-sided wildfire input.
Does Leduc flood?
The inventory has 0 studies for Leduc, and an empty list isn’t a clean bill: the municipality holds any flood maps.
Is Leduc at risk of wildfire?
Some, but Leduc’s low band (0% of nearby land burned since 1986, latest 2023) is short of the level that counts.
