Hazard risk in Electoral Area D, North Okanagan: B−
The grade weighs Electoral Area D, North Okanagan’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: #115 of 254 in British Columbia and #1,626 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.

What this data can and can’t tell you
- 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 Electoral Area D, North Okanagan until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Electoral Area D, North Okanagan without grading them.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Electoral Area D, North Okanagan’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Electoral Area D, North Okanagan’s.
