Fire reaches the land around Kenora, Unorganized now and then: 3% within 25 km since 1986 (0.08% a year), below the high band. Earthquakes matter little: NRCan’s model puts building losses at $0.006 a year per $1,000 of value, against $0.030 for the typical town. Hazard risk gives Kenora, Unorganized a grade of B; its wildfire band pulls it down.

Hazard risk in Kenora, Unorganized: B
The grade weighs Kenora, Unorganized’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #614 of 866 in Ontario and #1,405 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.

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 this data can and can’t tell you
- Wildfire counts one way. For Kenora, Unorganized, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Kenora, Unorganized without grading them.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Kenora, Unorganized’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 Kenora, Unorganized until then.
