Around Sanikiluaq, wildfire is practically absent from the record: 0% within 25 km since 1986, 0.000% a year. Seismic risk runs low: $0.006 of expected damage per $1,000 of buildings a year, the typical town $0.030. In Health Canada’s survey, just 0% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Sanikiluaq grades A+ for hazard risk, with wildfire counted against it.
What stands out about Sanikiluaq’s hazards
For Sanikiluaq, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Hazard risk in Sanikiluaq: A+
The grade weighs Sanikiluaq’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
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. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Sanikiluaq has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Sanikiluaq’s residents live, and the fuel next to their homes.
Forty years of fire maps put Sanikiluaq at 0.000% a year, low next to the typical Canadian town’s 0.000%.
Around Sanikiluaq the forest is thin or far off: 0% of the land within 5 km and 0% within 25 km is forest fuel.
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).
Measured against 2,610 towns, Sanikiluaq 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.

The flood map inventory lists nothing for Sanikiluaq
Flood studies whose area touches Sanikiluaq, from NRCan’s inventory, each linked to its owner.
There is no study for Sanikiluaq on the national flood inventory, which is far from complete.
Towns with a flood study on file
No inventory study touches Sanikiluaq, 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.
The grade leaves flood out, since a study area says nothing about how many of Sanikiluaq’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.”
Low seismic risk in Sanikiluaq: $0.006 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
0.2 times the typical $0.030: Sanikiluaq’s $0.006 is low for Canada.
Shaking damage a year per $1,000 of building value
With too few towns in Nunavut for a median of their own, Sanikiluaq is set beside Canada’s: $0.006 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.
Sanikiluaq is in the lower part of Canada’s range for earthquake risk; 88% of the 2,611 towns are higher.

0% of homes tested around Sanikiluaq are over the radon guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline.
Where the typical Canadian town has 6.6% of homes over the guideline, Sanikiluaq’s area has fewer, 0%. Figures for radon tests are published for the Nunavut health region as a whole, not for Sanikiluaq alone.

Over 600 Bq/m³
There is no median in Nunavut to compare with: the territory has too few towns, so Sanikiluaq’s 0% stands beside Canada’s figure.

Sanikiluaq 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.
A low area share in Sanikiluaq doesn’t clear a house, nor does a high one condemn it: test.

Get ready for what Sanikiluaq faces
What to do about the hazards Sanikiluaq 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. For Sanikiluaq, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Sanikiluaq’s census subdivision (a neighbourhood shows its city’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 Sanikiluaq until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Sanikiluaq without grading them.
