Burn scars are few around Attawapiskat 91A, with 1.3% of the land within 25 km touched by fire since 1986 (0.03% a year). Risk can’t be graded for Attawapiskat 91A: the seismic risk model doesn’t cover it.
What stands out about Attawapiskat 91A’s hazards
Four national sources, each read for Attawapiskat 91A: earthquakes, radon, past fires and flood studies.

Attawapiskat 91A can’t be graded for hazard risk
The grade weighs Attawapiskat 91A’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
As a First Nations reserve, Attawapiskat 91A gets no overall grade and no place in ranked lists.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.

No flood study is listed for Attawapiskat 91A
What Canada’s Flood Map Inventory lists for Attawapiskat 91A: who studied flooding and where to see their maps.
Nationally, Attawapiskat 91A has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Flood maps are common in Ontario, 69% of towns against 58% nationally, but none in the inventory touches Attawapiskat 91A.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping is shown for Attawapiskat 91A to be opened and checked, never turned into a grade.
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.”
Little radon around Attawapiskat 91A: 1% of area homes over the guideline

Get ready for what Attawapiskat 91A faces
What to do about the hazards Attawapiskat 91A 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. The wildfire figure is the share of land within 25 km of Attawapiskat 91A’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Attawapiskat 91A is its health region’s, the survey’s design unit.
- 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 Attawapiskat 91A’s.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Attawapiskat 91A.
Questions about flooding and hazards in Attawapiskat 91A
Does Attawapiskat 91A flood?
Nothing is listed for Attawapiskat 91A on the national inventory (0); local maps may still exist with the municipality.
Is radon a problem in Attawapiskat 91A?
In Health Canada’s survey, 1% of 96 homes tested in Attawapiskat 91A’s area were above 200 Bq/m³, though only a test tells you about one house.
How is Attawapiskat 91A’s Hazard risk Grade worked out?
Risk needs earthquakes, radon and wildfire, and Attawapiskat 91A is missing one, so there will be no grade.

Less than most of Canada: 1.3% of the land within 25 km of Attawapiskat 91A has burned since 1986, the last in 2023, a low band that leaves Risk alone.
