Flood mapping exists for Eleanor: 1 on record, latest by Hamilton Conservation Authority
Around Eleanor, wildfire is practically absent from the record: 0% within 25 km since 1986, 0.000% a year. Earthquake risk in Eleanor is ordinary: NRCan’s model puts building losses at $0.044 a year per $1,000 of value, close to the typical town’s $0.030. Radon around Eleanor is ordinary for Canada: 5% of tested homes over the guideline (6.6% typical). Hazard risk gives Eleanor a grade of B+, from earthquakes and radon alone.
What stands out about Eleanor’s hazards
Four national sources, each read for Eleanor: earthquakes, radon, past fires and flood studies.
What Eleanor faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Eleanor: B+
Two inputs always count for Eleanor, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #494 of 866 in Ontario and #1,255 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near Eleanor: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Eleanor’s residents live, and the fuel next to their homes.
Fire claims 0.000% of the land around Eleanor each year, a low band, with the typical Canadian town at 0.000%.
Little near Eleanor’s homes can carry a forest fire; only 0.2% of the land within 5 km is forest fuel, 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
To three decimals the burn rate around Eleanor 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.
Measured against 2,610 towns, Eleanor 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.

Hamilton Conservation Authority has mapped flooding for Eleanor (1 study)
Flood studies whose area touches Eleanor, from NRCan’s inventory, each linked to its owner.
One study on the inventory touches Eleanor, Hamilton Conservation Authority’s from 2025, and its area can be large, so it says a map exists, not that the town floods.

Towns with a flood study on file
69% of towns in Ontario have a flood study, more than Canada’s 58%; Eleanor has one too.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Eleanor.
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.”

Expected shaking damage in Eleanor: $0.044 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.
Eleanor’s $0.044 is close to the typical town’s $0.030 (1.5 times as much).
Shaking damage a year per $1,000 of building value
The median in Ontario is $0.043; Eleanor, at $0.044, is right beside it, and Alexandria tops the list at $0.21.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
In the upper part of Canada’s range: 32% of its 2,611 towns expect more damage than Eleanor.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
Roads, pipes and bridges aren’t in Eleanor’s figure, nor landslides or tsunami: it is buildings and shaking.

Some radon around Eleanor: 5% of area homes over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline.
At 5% over the guideline, the area around Eleanor is about level with the typical Canadian town’s 6.6%.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
The median in Ontario is 4% over 200 Bq/m³; the survey area around Eleanor has 5%.
Health Canada radon survey (2009–2011), by 2007 health region; medians of towns of 2,500 people or more.
A middling share of high tests puts Eleanor with 37% of Canada’s 2,611 towns, below 26% of them.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
A survey sample isn’t a map: any home in Eleanor can be high, and a three-month test is the only way to know.

Templemead (low) has the heaviest fire record of Eleanor’s neighbours, and Eleanor (low) matches or beats it.
Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Eleanor faces
What to do about the hazards Eleanor 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
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Eleanor’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 Eleanor’s.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Eleanor 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 Eleanor until then.
Questions about flooding and hazards in Eleanor
Is Eleanor at risk of wildfire?
Hardly at all on record: 0% of the land within 25 km of Eleanor since 1986, a low band, though small grass fires aren’t mapped.
Does Eleanor flood?
A flood study covers Eleanor on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
Is radon a problem in Eleanor?
Around Eleanor, 100 survey homes were tested and 5% came in over 200 Bq/m³, a guide to the area, not to any one home.
How big is the earthquake risk in Eleanor?
About $0.044 a year per $1,000 of building value, NRCan’s long-run expectation for Eleanor.
How is Eleanor’s Hazard risk Grade worked out?
Eleanor’s Hazard risk grade is B+, built on earthquakes and radon with a one-sided wildfire input.
