East End-Danforth grades A− for hazard risk
Seismic risk and radon set East End-Danforth’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. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near East End-Danforth: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where East End-Danforth’s residents live, and the fuel next to their homes.
In a typical year 0.001% of the land near East End-Danforth burns; the typical Canadian town sees 0.000%, and both are low.
No fire has burned within 5 km of East End-Danforth’s homes since 1986; the nearest burn is 23 km away.
Forest fuel is scarce around East End-Danforth: 0.5% of the land within 5 km, 1.4% 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
In the top quarter in Ontario: East End-Danforth ranks 83rd of 871 at 0.001% a year, with Sioux Lookout first 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.
Beside 2,610 Canadian towns, East End-Danforth reads low, with 92% of them; only 7.5% rank higher.
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.

Get ready for what East End-Danforth faces
Practical steps for East End-Danforth’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. For East End-Danforth, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for East End-Danforth’s census subdivision (a neighbourhood shows its city’s).
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, East End-Danforth 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 East End-Danforth.
Questions about flooding and hazards in East End-Danforth
Is East End-Danforth at risk of wildfire?
Some, but East End-Danforth’s low band (0% of nearby land burned since 1986, latest 2001) is short of the level that counts.
Does East End-Danforth flood?

How is East End-Danforth’s Hazard risk Grade worked out?
Hazard risk gives East End-Danforth A−, weighing earthquakes and radon and counting wildfire only against it.
Is radon a problem in East End-Danforth?
The area’s survey found 2.7% of 74 tested homes above Health Canada’s guideline, so a three-month test is worth doing in East End-Danforth.
