Wildfire barely registers for Beasley, at 0% of the land within 25 km since 1986 (0.000% a year). Seismic risk in Beasley sits near the middle: $0.044 of expected damage per $1,000 of buildings a year, the typical town $0.030. Beasley grades B+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Beasley’s hazards
For Beasley, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Beasley faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Beasley grades B+ for hazard risk
Two inputs always count for Beasley, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #494 of 866 in Ontario and #1,255 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Beasley has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Beasley’s homes, from the national burned-area record, with the fuel within 5 km.
Forty years of fire maps put Beasley at 0.000% a year, low next to the typical Canadian town’s 0.000%.
Only 1.9% of the land within 25 km of Beasley is forest fuel, and 1.2% close in.

Burn rate a year, towns in Ontario · highest of 871
Near-zero burning puts Beasley with 638 of the 871 towns in Ontario, far below Sioux Lookout at 0.16%.
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.
92% of Canada’s 2,610 towns are in the low band and 7.5% above it; Beasley is among the many where the yearly burn rate rounds to zero.
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 Beasley
What Canada’s Flood Map Inventory lists for Beasley: who studied flooding and where to see their maps.
No flood study on the national inventory covers Beasley; ask the municipality, which is the authority for its flood maps.
Towns with a flood study on file
Missing from a well-mapped province: Beasley has no study, where 69% of towns in Ontario have one against 58% nationally.
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 Beasley 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 Beasley: $0.044 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Beasley’s $0.044 is close to the typical town’s $0.030 (1.5 times as much).
Nobody publishes earthquake risk for Beasley alone, so this card uses the figure for the city of Hamilton.
Shaking damage a year per $1,000 of building value
Earthquake risk around Beasley ($0.044) matches the middle in Ontario ($0.043), far from Alexandria’s $0.21.

Beasley sits above most of Canada’s 2,611 towns on earthquake risk; 32% are higher.
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).
Only shaking damage to buildings in Beasley is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Get ready for what Beasley faces
What to do about the hazards Beasley 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. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Beasley sits in.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Beasley’s included.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Beasley floods.
- 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 Beasley.
