The national fire record shows next to nothing around Roxton Pond, 0% of the land within 25 km since 1986 (0.000% a year). Earthquakes add more: NRCan’s model puts building losses at $0.071 a year per $1,000 of value, against $0.030 for the typical town. Roxton Pond grades C+ for hazard risk; wildfire is low here, so it earns no credit.

Hazard risk in Roxton Pond: C+
The grade weighs Roxton Pond’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: #119 of 507 in Quebec and #1,863 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.
Little of the land around Roxton Pond has burned: 0% within 5 km, 0% within 25 km since 1986

The flood map inventory lists nothing for Roxton Pond
What Canada’s Flood Map Inventory lists for Roxton Pond: who studied flooding and where to see their maps.
NRCan’s inventory is silent on Roxton Pond, so any flood map would be the municipality’s own.
Towns with a flood study on file
Only 45% of towns in Quebec have a flood study, short of Canada’s 58%, and Roxton Pond is not among them.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Roxton Pond.
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.”

Get ready for what Roxton Pond faces
What to do about the hazards Roxton Pond 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.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
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 Roxton Pond until then.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Roxton Pond’s figure is its subdivision’s.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Roxton Pond’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Roxton Pond without grading them.
