The national fire record shows next to nothing around Armour, 0% of the land within 25 km since 1986 (0.000% a year). Shaking is about as much of a worry in Armour as in most places, at $0.022 a year per $1,000 of building value ($0.030 typical). Radon is lower than usual: 1.9% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Armour a grade of A, from earthquakes and radon alone.
What stands out about Armour’s hazards
Four national sources, each read for Armour: earthquakes, radon, past fires and flood studies.
What Armour faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Armour grades A for hazard risk
Earthquake risk and radon make Armour’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
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.
Wildfire is rare near Armour: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Armour’s homes, from the national burned-area record, with the fuel within 5 km.
In a typical year 0.000% of the land near Armour burns; the typical Canadian town sees 0.000%, and both are low.
About as much forest grows next to Armour’s homes (20% within 5 km) as across 25 km (23%).

Burn rate a year, towns in Ontario · highest of 872
Near-zero burning puts Armour with 639 of the 872 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.
Armour shares the low band with 92% of Canada’s 2,610 towns, its burn rate rounding to nothing; 7.5% burn faster.
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.

The flood map inventory lists nothing for Armour
What Canada’s Flood Map Inventory lists for Armour: who studied flooding and where to see their maps.
Nationally, Armour has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Armour has no flood study on file, though 69% of towns in Ontario do (Canada: 58%).
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Listed, not scored: a flood study proves a map exists, not that Armour floods.
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.”
Earthquakes cost buildings in Armour $0.022 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
0.7 times the typical $0.030: Armour’s $0.022 is ordinary.
Shaking damage a year per $1,000 of building value
The typical town in Ontario expects $0.043 a year in shaking damage; Armour expects less, $0.022, and Alexandria the most, $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.
Armour’s earthquake risk lands near the centre of Canada’s range; 61% of the 2,611 towns are higher.
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).
The loss is to Armour’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Little radon around Armour: 1.9% of area homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Fewer homes than usual test high around Armour: 1.9% against 6.6% for the typical Canadian town. For radon tests, the only official count covers all of the North Bay Parry Sound District Health Unit, Armour included.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Against the typical town in Ontario (4%), the area around Armour has fewer high tests: 1.9%.

63% of Canada’s 2,611 towns have a higher share of homes over 200 Bq/m³ than Armour’s band, which holds 37%.
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 Armour can be high, and a three-month test is the only way to know.

Get ready for what Armour faces
Practical steps for Armour’s hazards, most pressing first.
- 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
- 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 Armour’s.
- 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 Armour until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Armour without grading them.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Armour’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.

How is Armour’s Hazard risk Grade worked out?
Armour grades A for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
Is radon a problem in Armour?
The area’s survey found 1.9% of 103 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Armour.
