Shaking is less of a worry than in most places, at $0.009 a year per $1,000 of building value ($0.030 typical). In Health Canada’s survey, just 0% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Arctic Bay can’t get a Hazard risk grade: it lies north of the fuel map, so its wildfire risk can’t be measured. Arctic Bay grades A+ for hazard risk, without a wildfire figure.
What stands out about Arctic Bay’s hazards
Four national sources, each read for Arctic Bay: earthquakes, radon, past fires and flood studies.
What Arctic Bay faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.
Earthquakes
Radon
Flood study
Hazard risk in Arctic Bay: A+
Two inputs always count for Arctic Bay, earthquakes and radon; the third, wildfire, counts only against a town.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 78 homes were tested in the survey area, so the radon share is rough.
Wildfire isn’t measured for Arctic Bay
Arctic Bay lies north of the national fuel map, so its wildfire risk isn’t measured, and Risk can’t be graded without it.
The flood map inventory lists nothing for Arctic Bay
What Canada’s Flood Map Inventory lists for Arctic Bay: who studied flooding and where to see their maps.
Nationally, Arctic Bay has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Arctic Bay has no flood study on file; 58% of Canada’s towns have one.
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 Arctic Bay’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.”
Earthquakes cost buildings in Arctic Bay just $0.009 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Arctic Bay’s $0.009 is a fraction of the typical town’s $0.030 (0.3 times as much): quiet ground by Canadian standards.
Shaking damage a year per $1,000 of building value
With too few towns in Nunavut for a median of their own, Arctic Bay is set beside Canada’s: $0.009 against $0.030.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Earthquakes cost less around Arctic Bay than in 86% of Canada’s 2,611 towns.
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 model counts damage to Arctic Bay’s buildings and their occupants from shaking only: not liquefaction, landslides, tsunami or fires after a quake.

Radon runs low around Arctic Bay: 0% of tested homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Arctic Bay’s survey area reads 0% over the guideline, under the typical Canadian town’s 6.6%.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
There is no median in Nunavut to compare with: the territory has too few towns, so Arctic Bay’s 0% stands beside Canada’s figure.
Health Canada radon survey (2009–2011), by 2007 health region; medians of towns of 2,500 people or more.
Arctic Bay is in the lowest band, with 37% of Canada’s 2,611 towns: under 5% of tests over the guideline, while 63% have more.
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.
Basements, soil and how a house is sealed decide its radon, so in Arctic Bay only a test can say.

Get ready for what Arctic Bay faces
What to do about the hazards Arctic Bay 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.
- How close is the forest edge?
- Are flood and wildfire insured?
What this data can and can’t tell you
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Arctic Bay floods.
- 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 Arctic Bay’s.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Arctic Bay sits in.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Arctic Bay’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
Questions about flooding and hazards in Arctic Bay
Does Arctic Bay flood?
Nothing is listed for Arctic Bay on the national inventory (0); local maps may still exist with the municipality.
How is Arctic Bay’s Hazard risk Grade worked out?
Hazard risk gives Arctic Bay A+, weighing earthquakes and radon and counting wildfire only against it.
Is radon a problem in Arctic Bay?
In Health Canada’s survey, 0% of 78 homes tested in Arctic Bay’s area were above 200 Bq/m³, though only a test tells you about one house.
How big is the earthquake risk in Arctic Bay?
In NRCan’s seismic model, Arctic Bay’s buildings lose $0.009 per $1,000 of value in an average year.
