Shaking is less of a worry than in most places, at $0.007 a year per $1,000 of building value ($0.030 typical). Radon is lower than usual: 0% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Iqaluit can’t get a Hazard risk grade: it lies north of the fuel map, so its wildfire risk can’t be measured. Iqaluit grades A+ for hazard risk, without a wildfire figure.
What stands out about Iqaluit’s hazards
Four national sources, each read for Iqaluit: earthquakes, radon, past fires and flood studies.
What Iqaluit faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.
Earthquakes
Radon
Flood study
Hazard risk in Iqaluit: A+
Earthquake risk and radon make Iqaluit’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #4 of 2,589 Canadian towns.
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 Iqaluit
Iqaluit 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 Iqaluit
What Canada’s Flood Map Inventory lists for Iqaluit: who studied flooding and where to see their maps.
An empty entry for Iqaluit on the inventory isn’t proof of safety; ask locally for flood maps.
Towns with a flood study on file
No inventory study touches Iqaluit, where 58% of Canadian towns have one.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood studies don’t enter the grade; they are listed so you can open the official map for Iqaluit.
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 Iqaluit just $0.007 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
At $0.007 per $1,000, Iqaluit carries 0.2 times the typical Canadian town’s earthquake risk ($0.030): low.
Shaking damage a year per $1,000 of building value
Iqaluit’s $0.007 is measured against Canada’s median of $0.030, since few towns in Nunavut reach 2,500 people.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Most of Canada’s 2,611 towns (88%) face more earthquake damage than Iqaluit.
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 Iqaluit’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

0% of homes tested around Iqaluit are over the radon guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Where the typical Canadian town has 6.6% of homes over the guideline, Iqaluit’s area has fewer, 0%.
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 Iqaluit’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.
Few tests over the guideline: Iqaluit shares the bottom band with 37% of Canada’s 2,611 towns, below the other 63%.
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.

Weather and fire alerts for Iqaluit
Alerts for Iqaluit come from Environment and Climate Change Canada and, for emergencies, Alert Ready.
| Alert | What it means |
|---|---|
| Warning | Severe weather is happening or about to: act now. |
| Watch | Conditions favour severe weather: be ready. |
| Advisory | Weather that is less severe but could disrupt the day. |
| Special weather statement | Unusual weather worth knowing about. |
| Special air quality statement | Poor air, often wildfire smoke. |
Alert Ready carries evacuation orders for Iqaluit to phones; CWFIS shows the day’s fire danger.

Get ready for what Iqaluit faces
Practical steps for Iqaluit’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.
- How close is the forest edge?
- 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 Iqaluit’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. 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 Iqaluit floods.
- 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 Iqaluit sits in.
- 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 Iqaluit’s.
Questions about flooding and hazards in Iqaluit
Does Iqaluit flood?
No study on Canada’s Flood Map Inventory covers Iqaluit (0), which doesn’t mean it has never been mapped, so ask the municipality.
How is Iqaluit’s Hazard risk Grade worked out?
Hazard risk gives Iqaluit A+, weighing earthquakes and radon and counting wildfire only against it.
How big is the earthquake risk in Iqaluit?
In NRCan’s seismic model, Iqaluit’s buildings lose $0.007 per $1,000 of value in an average year.
Is radon a problem in Iqaluit?
0% of the 78 homes Health Canada tested around Iqaluit topped the guideline; your own house needs its own test.
