No wildfire is mapped within 25 km of Battlefield’s homes since 1986 (0% of the land, 0.000% a year). NRCan expects $0.044 of shaking damage a year per $1,000 of buildings in Battlefield, near the typical $0.030. About as many homes carry radon around Battlefield as elsewhere, 5% over the guideline where the typical town has 6.6%. Hazard risk gives Battlefield a grade of B+, from earthquakes and radon alone.
What stands out about Battlefield’s hazards
Four national sources, each read for Battlefield: earthquakes, radon, past fires and flood studies.
What Battlefield faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Battlefield grades B+ for hazard risk
Earthquake risk and radon make Battlefield’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #494 of 866 in Ontario and #1,255 of 2,589 Canadian towns.
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.
Little of the land around Battlefield has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Battlefield’s homes, from the national burned-area record, with the fuel within 5 km.
Low by Canadian standards: 0.000% of the land a year around Battlefield, 0.000% for the typical Canadian town.
Only 0.7% of the land within 25 km of Battlefield is forest fuel, and 0.1% close in.

Burn rate a year, towns in Ontario · highest of 871
Among the 871 towns in Ontario, Sioux Lookout burns fastest (0.16% a year); Battlefield is with the 638 near 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.
Most of the country’s 2,610 towns are low-band (92%, against 7.5% above); around Battlefield, burning 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.

Towns with a flood study on file
Mapping in Ontario reaches 69% of towns, Battlefield included, beside 58% across Canada.
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 Battlefield 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.”

Ordinary seismic risk in Battlefield: $0.044 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
With $0.044 of shaking damage a year per $1,000, Battlefield is about even with the typical $0.030 (1.5 times).
Battlefield doesn’t get its own earthquake risk figures; the ones here come from the city of Hamilton.
Shaking damage a year per $1,000 of building value
Neither high nor low in Ontario: Battlefield’s $0.044 sits by the median of $0.043, while Alexandria reaches $0.21.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Battlefield 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).
The loss is to Battlefield’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Some radon around Battlefield: 5% of area homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Around Battlefield, 5% of tested homes topped the guideline, near the typical Canadian town’s 6.6%.

Between 5% and 10% of tests over the guideline: Battlefield, and 37% of Canada’s 2,611 towns; 26% are higher.
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.
The share describes the area, not a house: in Battlefield as anywhere, test to be sure.

Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Battlefield faces
Practical steps for Battlefield’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
- Wildfire counts one way. Wildfire is read from the national burned-area record around Battlefield’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Battlefield’s figure is its subdivision’s.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Battlefield takes its 2007 health region’s share.
- 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 Battlefield.
Questions about flooding and hazards in Battlefield
How big is the earthquake risk in Battlefield?
In NRCan’s seismic model, Battlefield’s buildings lose $0.044 per $1,000 of value in an average year.
How is Battlefield’s Hazard risk Grade worked out?
Battlefield’s Hazard risk grade is B+, built on earthquakes and radon with a one-sided wildfire input.
Is Battlefield at risk of wildfire?
Very little by the national record: Battlefield’s band is low, with 0% of the land within 25 km burned since 1986, so wildfire doesn’t change its grade.
Is radon a problem in Battlefield?
The area’s survey found 5% of 100 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Battlefield.
Does Battlefield flood?
The inventory lists a study touching Battlefield; whether a given street floods is on that map, not in the grade.
