Fire seldom reaches Campbellton: since 1986, 0.1% of the land within 25 km has burned (0.003% a year). Seismic risk in Campbellton sits near the middle: $0.038 of expected damage per $1,000 of buildings a year, the typical town $0.030. Campbellton grades C− for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Campbellton’s hazards
Four national sources, each read for Campbellton: earthquakes, radon, past fires and flood studies.
What Campbellton faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Campbellton: C−
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Campbellton with little fire nearby would get no credit for it.
Its place: #43 of 60 in New Brunswick and #2,406 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Campbellton has burned: 1.8% within 5 km, 0.1% within 25 km since 1986
Past fire around Campbellton’s homes, from the national burned-area record, with the fuel within 5 km.
In a typical year 0.003% of the land near Campbellton burns; the typical Canadian town sees 0.000%, and both are low.
The nearer ring around Campbellton is less wooded (30% forest fuel) than the land out to 25 km (54%).

The low band takes in 92% of Canada’s 2,610 towns, Campbellton among them, though its rate is above zero; 7.5% rank higher.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Flood studies don’t enter the grade; they are listed so you can open the official map for Campbellton.
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.

24% of homes tested around Campbellton are over the radon guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Campbellton’s area, at 24%, is above the 6.6% of the typical Canadian town, so testing is worth more here than most places. Nobody publishes radon tests for Campbellton alone, so this card uses the figure for the Region 5 health region.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Ordinary for towns in New Brunswick at 24% over 200 Bq/m³ (20% is the median), the area around Campbellton had 4.5% over 600.

Get ready for what Campbellton faces
What to do about the hazards Campbellton 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?
- 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. The wildfire figure is the share of land within 25 km of Campbellton’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Campbellton’s.
- 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 Campbellton.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Campbellton takes its 2007 health region’s share.

Is radon a problem in Campbellton?
Around Campbellton, 110 survey homes were tested and 24% came in over 200 Bq/m³, a guide to the area, not to any one home.

Is Campbellton at risk of wildfire?
Fire has reached 0.1% of the land around Campbellton since 1986 (last in 2025); at low, it neither helps nor hurts the grade.
