Wildfire isn’t West River’s worry: 0% of the land within 25 km burned since 1986 (0.000% a year). Earthquake risk in West River is ordinary: NRCan’s model puts building losses at $0.016 a year per $1,000 of value, close to the typical town’s $0.030. Radon is lower than usual: 3.5% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives West River a grade of A, from earthquakes and radon alone.
What stands out about West River’s hazards
For West River, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What West River faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

West River grades A for hazard risk
Earthquake risk and radon make West River’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #1 of 12 on Prince Edward Island and #409 of 2,589 Canadian towns.
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.
Wildfire is rare near West River: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around West River’s homes, from the national burned-area record, with the fuel within 5 km.
At 0.000% of the land a year, West River’s burn rate is in the low band; the typical Canadian town sees 0.000%.
Forest crowds in on West River: 21% of the land within 5 km is forest fuel, more than the 16% within 25 km.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).

Towns with a flood study on file
100% of towns on Prince Edward Island have a flood study, more than Canada’s 58%; West River has one too.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping is shown for West River to be opened and checked, never turned into a grade.
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 West River faces
Practical steps for West River’s hazards, most pressing first.
- 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?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. For West River, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- 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 West River.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for West River’s census subdivision (a neighbourhood shows its city’s).
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, West River takes its 2007 health region’s share.
Questions about flooding and hazards in West River
How is West River’s Hazard risk Grade worked out?
West River grades A for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
How big is the earthquake risk in West River?
In NRCan’s seismic model, West River’s buildings lose $0.016 per $1,000 of value in an average year.
Is radon a problem in West River?
3.5% of the 113 homes Health Canada tested around West River topped the guideline; your own house needs its own test.
Does West River flood?
The inventory lists a study touching West River; whether a given street floods is on that map, not in the grade.
Is West River at risk of wildfire?
Very little by the national record: West River’s band is low, with 0% of the land within 25 km burned since 1986, so wildfire doesn’t change its grade.
