Burn scars are few around Wikwemikong Unceded, with 0.1% of the land within 25 km touched by fire since 1986 (0.004% a year). Seismic risk runs low: $0.009 of expected damage per $1,000 of buildings a year, the typical town $0.030. About as many homes carry radon around Wikwemikong Unceded as elsewhere, 5.2% over the guideline where the typical town has 6.6%. Hazard risk gives Wikwemikong Unceded a grade of A; its wildfire band pulls it down.

Wikwemikong Unceded grades A for hazard risk
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Wikwemikong Unceded with little fire nearby would get no credit for it.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.

No flood study is listed for Wikwemikong Unceded
What Canada’s Flood Map Inventory lists for Wikwemikong Unceded: who studied flooding and where to see their maps.
An empty entry for Wikwemikong Unceded on the inventory isn’t proof of safety; ask locally for flood maps.
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 Wikwemikong Unceded.
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 Wikwemikong Unceded’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.”

What to do about the hazards Wikwemikong Unceded 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.

What this data can and can’t tell you
- Wildfire counts one way. For Wikwemikong Unceded, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Wikwemikong Unceded is its health region’s, the survey’s design unit.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Wikwemikong Unceded’s census subdivision (a neighbourhood shows its city’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 Wikwemikong Unceded.
