What stands out about East Windsor’s hazards
Four national sources, each read for East Windsor: earthquakes, radon, past fires and flood studies.
What East Windsor faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in East Windsor: C+
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like East Windsor with little fire nearby would get no credit for it.
Its place: #682 of 866 in Ontario and #1,870 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near East Windsor: 0% within 5 km, 0.2% within 25 km
Fires mapped since 1986 around where East Windsor’s residents live, and the fuel next to their homes.
Low by Canadian standards: 0.007% of the land a year around East Windsor, 0.000% for the typical Canadian town.
No fire has burned within 5 km of East Windsor’s homes since 1986; the nearest burn is 8.2 km away.
Only 0.3% of the land within 25 km of East Windsor is forest fuel, and 0.3% close in.

Towns with a flood study on file
Mapping in Ontario reaches 69% of towns, East Windsor included, beside 58% across Canada.
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 East Windsor’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.”

Get ready for what East Windsor faces
What to do about the hazards East Windsor faces, and what to ask before you buy.
- 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. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for East Windsor.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for East Windsor is its health region’s, the survey’s design unit.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of East Windsor’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as East Windsor’s.
