Around Eganville, wildfire is practically absent from the record: 0% within 25 km since 1986, 0.000% a year. Seismic risk runs high: $0.070 of expected damage per $1,000 of buildings a year, the typical town $0.030. Hazard risk gives Eganville a grade of C+, from earthquakes and radon alone.
What stands out about Eganville’s hazards
For Eganville, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Eganville grades C+ for hazard risk
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Eganville with little fire nearby would get no credit for it.
Its place: #675 of 866 in Ontario and #1,799 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Eganville: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Eganville’s residents live, and the fuel next to their homes.
Next to the typical Canadian town (0.000% a year), Eganville’s 0.000% is in the low band.
The closest burn since 1986 lies 22 km from Eganville’s homes, none within 5 km.
More forest grows near Eganville’s homes (42% within 5 km) than across 25 km (37%).

Burn rate a year, towns in Ontario · highest of 871
To three decimals the burn rate around Eganville is zero, as for 638 of the 871 towns in Ontario, while Sioux Lookout reaches 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.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Eganville, at a rounded zero, is far from them.

The flood map inventory lists nothing for Eganville
Flood studies whose area touches Eganville, from NRCan’s inventory, each linked to its owner.
The inventory has nothing for Eganville, but a local or conservation-authority map may still exist.
Towns with a flood study on file
Mapping in Ontario reaches 69% of towns, beside 58% across Canada, but not Eganville.
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 Eganville’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.”
Shaking is Eganville’s costliest hazard: $0.070 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.070 per $1,000, Eganville carries roughly 2.3 times the typical Canadian town’s earthquake risk ($0.030).

Get ready for what Eganville faces
What to do about the hazards Eganville 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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- 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 Eganville.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Eganville’s included.
- 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 Eganville until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Eganville without grading them.
