Hazard risk in Rivers Edge / Castlemore Crossing is lower than in 89% of Canadian towns
Wildfire isn’t Rivers Edge / Castlemore Crossing’s worry: 0% of the land within 25 km burned since 1986 (0.000% a year). Earthquake risk in Rivers Edge / Castlemore Crossing 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. Fewer homes than usual carry radon here, 0% over the guideline where the typical town has 6.6%. Rivers Edge / Castlemore Crossing grades A for hazard risk; wildfire is low here, so it earns no credit.

Rivers Edge / Castlemore Crossing grades A for hazard risk
The grade weighs Rivers Edge / Castlemore Crossing’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: #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. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near Rivers Edge / Castlemore Crossing: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Rivers Edge / Castlemore Crossing’s homes, from the national burned-area record, with the fuel within 5 km.
Low: the land around Rivers Edge / Castlemore Crossing burns at 0.000% a year, where the typical Canadian town sees 0.000%.
Around Rivers Edge / Castlemore Crossing the forest is thin or far off: 1.1% of the land within 5 km and 4.7% within 25 km is forest fuel.

What this data can and can’t tell you
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Rivers Edge / Castlemore Crossing’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Rivers Edge / Castlemore Crossing.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Rivers Edge / Castlemore Crossing takes its 2007 health region’s share.
- 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 Rivers Edge / Castlemore Crossing’s.
