Wildfire barely registers for Bartonville, at 0% of the land within 25 km since 1986 (0.000% a year). NRCan expects $0.044 of shaking damage a year per $1,000 of buildings in Bartonville, near the typical $0.030. Radon around Bartonville is ordinary for Canada: 5% of tested homes over the guideline (6.6% typical). Hazard risk gives Bartonville a grade of B+, from earthquakes and radon alone.
What stands out about Bartonville’s hazards
For Bartonville, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Bartonville faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Bartonville grades B+ for hazard risk
Earthquake risk and radon make Bartonville’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. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Bartonville: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Bartonville’s residents live, and the fuel next to their homes.
With 0.000% burned a year, Bartonville is among the many low-band places (the typical Canadian town 0.000%).
Little near Bartonville’s homes can carry a forest fire; only 0.1% of the land within 5 km is forest fuel, and 0.8% 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 Ontario · highest of 871
Of the 871 towns in Ontario, 638 have a burn rate that rounds to zero, Bartonville among them; Sioux Lookout leads at 0.16% a year.
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.
Bartonville shares the low band with 92% of Canada’s 2,610 towns, its burn rate rounding to nothing; 7.5% burn faster.
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 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.

Ordinary seismic risk in Bartonville: $0.044 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Bartonville’s $0.044 is close to the typical town’s $0.030 (1.5 times as much).
Nobody publishes earthquake risk for Bartonville alone, so this card uses the figure for the city of Hamilton.
Shaking damage a year per $1,000 of building value
Bartonville’s $0.044 is close to the median in Ontario, $0.043; Alexandria is highest at $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.
Bartonville sits above most of Canada’s 2,611 towns on earthquake risk; 32% are higher.

Get ready for what Bartonville faces
Practical steps for Bartonville’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
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Bartonville 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 Bartonville.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Bartonville’s included.
- 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 Bartonville.
