Wildfire barely registers for Florenceville-Bristol, at 0% of the land within 25 km since 1986 (0.000% a year). Earthquake risk in Florenceville-Bristol is ordinary: NRCan’s model puts building losses at $0.042 a year per $1,000 of value, close to the typical town’s $0.030. Florenceville-Bristol grades C− for hazard risk; wildfire is low here, so it earns no credit.

What Florenceville-Bristol faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Florenceville-Bristol: C−
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Florenceville-Bristol with little fire nearby would get no credit for it.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. 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.”

Get ready for what Florenceville-Bristol faces
What to do about the hazards Florenceville-Bristol 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
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Florenceville-Bristol’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Florenceville-Bristol, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Florenceville-Bristol takes its 2007 health region’s share.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Florenceville-Bristol.
