Centreville-Wareham-Trinity grades A+ for hazard risk
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Centreville-Wareham-Trinity with little fire nearby would get no credit for it.
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.

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
- 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 Centreville-Wareham-Trinity until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Centreville-Wareham-Trinity without grading them.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Centreville-Wareham-Trinity’s figure is its subdivision’s.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Centreville-Wareham-Trinity’s homes since 1986, a history of fire that may lower Risk but never raises it.
