Since 1986 almost nothing has burned near Eringate-Centennial-West Deane: 0% of the land within 25 km, or 0.000% a year. Shaking is about as much of a worry in Eringate-Centennial-West Deane as in most places, at $0.043 a year per $1,000 of building value ($0.030 typical). Fewer homes than usual carry radon here, 2.7% over the guideline where the typical town has 6.6%. Eringate-Centennial-West Deane grades A− for hazard risk; wildfire is low here, so it earns no credit.

Eringate-Centennial-West Deane grades A− for hazard risk
The grade weighs Eringate-Centennial-West Deane’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
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. 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 Eringate-Centennial-West Deane has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Eringate-Centennial-West Deane’s residents live, and the fuel next to their homes.
Forty years of fire maps put Eringate-Centennial-West Deane at 0.000% a year, low next to the typical Canadian town’s 0.000%.
Land that isn’t forest covers nearly all the ground around Eringate-Centennial-West Deane: forest fuel is 0.2% within 5 km and 0.8% 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
Near-zero burning puts Eringate-Centennial-West Deane with 638 of the 871 towns in Ontario, far below Sioux Lookout 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.
Measured against 2,610 towns, Eringate-Centennial-West Deane is in the largest group, low (92%), and at its floor, while 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.

Eringate-Centennial-West Deane is on the flood map inventory: 1 study, by Toronto Regional Conservation Authority
Flood studies whose area touches Eringate-Centennial-West Deane, from NRCan’s inventory, each linked to its owner.
One study on the inventory touches Eringate-Centennial-West Deane, Toronto Regional Conservation Authority’s from 2021, and its area can be large, so it says a map exists, not that the town floods.

Towns with a flood study on file
Its flood study puts Eringate-Centennial-West Deane with 69% of towns in Ontario; Canada’s share is 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of Eringate-Centennial-West Deane’s homes are at risk.
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.”

What this data can and can’t tell you
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Eringate-Centennial-West Deane without grading them.
- Radon is a survey. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around Eringate-Centennial-West Deane until then.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Eringate-Centennial-West Deane’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Eringate-Centennial-West Deane’s figure is its subdivision’s.
