No wildfire is mapped within 25 km of Clanton Park’s homes since 1986 (0% of the land, 0.000% a year). Seismic risk in Clanton Park sits near the middle: $0.043 of expected damage per $1,000 of buildings a year, the typical town $0.030. Fewer homes than usual carry radon here, 2.7% over the guideline where the typical town has 6.6%. Hazard risk gives Clanton Park a grade of A−, from earthquakes and radon alone.

Clanton Park grades A− for hazard risk
Seismic risk and radon set Clanton Park’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #285 of 866 in Ontario and #700 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 74 homes were tested in the survey area, so the radon share is rough. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Clanton Park has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Clanton Park’s homes, from the national burned-area record, with the fuel within 5 km.
A burn rate of 0.000% a year keeps Clanton Park in the low band (the typical Canadian town: 0.000%).
With 0.1% forest fuel within 5 km and 1.8% within 25 km, the land around Clanton Park gives a fire little to burn.
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, Clanton Park 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.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Clanton Park, 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
Clanton Park is one of the 69% of towns in Ontario with a flood study on file; across Canada it is 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of Clanton Park’s homes stand in a flood zone.
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 Clanton Park: $0.043 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Nothing unusual about Clanton Park’s ground: $0.043 against a typical $0.030, 1.4 times.

Get ready for what Clanton Park faces
Practical steps for Clanton Park’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. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Clanton Park’s figure is its subdivision’s.
- 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 Clanton Park.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Clanton Park takes its 2007 health region’s share.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Clanton Park’s homes since 1986, a history of fire that may lower Risk but never raises it.
Questions about flooding and hazards in Clanton Park
Is Clanton Park at risk of wildfire?
