Hazard risk in Queenswood - Chatelaine: C+
Two inputs always count for Queenswood - Chatelaine, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #703 of 866 in Ontario and #1,894 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 64 homes were tested in the survey area, so the radon share is rough. Small fires and grass fires are largely missing from the national burned-area record.

Towns with a flood study on file
Queenswood - Chatelaine is one of the 69% of towns in Ontario with a flood study on file; across Canada it is 58%.
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 Queenswood - Chatelaine’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 this data can and can’t tell you
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Queenswood - Chatelaine’s figure is its subdivision’s.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Queenswood - Chatelaine floods.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Queenswood - Chatelaine’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Queenswood - Chatelaine sits in.
