Few places are as safe from hazards as Wildfield: it beats 89% of Canadian towns
Wildfire isn’t Wildfield’s worry: 0% of the land within 25 km burned since 1986 (0.000% a year). Earthquake risk in Wildfield is ordinary: NRCan’s model puts building losses at $0.030 a year per $1,000 of value, close to the typical town’s $0.030. In Health Canada’s survey, just 0% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Wildfield grades A for hazard risk; wildfire is low here, so it earns no credit.

Hazard risk in Wildfield: A
Earthquake risk and radon make Wildfield’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #105 of 866 in Ontario and #417 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 Wildfield: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Wildfield’s homes, from the national burned-area record, with the fuel within 5 km.
A burn rate of 0.000% a year keeps Wildfield in the low band (the typical Canadian town: 0.000%).
Close to Wildfield there is little to burn (0.3% forest fuel within 5 km), but 6.9% of the land within 25 km is forest.
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

Listed, not scored: a flood study proves a map exists, not that Wildfield 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.”

Get ready for what Wildfield faces
Practical steps for Wildfield’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. 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 Wildfield.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Wildfield 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 Wildfield.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Wildfield’s included.

Is Wildfield at risk of wildfire?
No meaningful wildfire history near Wildfield: 0% of nearby land since 1986, band low.
Is radon a problem in Wildfield?
The area’s survey found 0% of 90 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Wildfield.
