No wildfire is mapped within 25 km of Danforth East York’s homes since 1986 (0% of the land, 0.001% a year). Earthquake risk in Danforth East York is ordinary: NRCan’s model puts building losses at $0.043 a year per $1,000 of value, close to the typical town’s $0.030. In Health Canada’s survey, just 2.7% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Hazard risk gives Danforth East York a grade of A−; its wildfire band pulls it down.

Hazard risk in Danforth East York: A−
Seismic risk and radon set Danforth East York’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: The seismic figure is a long-run average from NRCan’s model, not a prediction. The radon share rests on 74 home tests in the survey area, so a few homes move it. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Danforth East York has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Danforth East York’s residents live, and the fuel next to their homes.

Practical steps for Danforth East York’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
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Danforth East York floods.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Danforth East York’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 Danforth East York.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Danforth East York sits in.
