Wildfire is rare near Bedford: 2% of the land within 25 km has burned since 1986, a burn rate of 0.05% a year. Shaking is about as much of a worry in Bedford as in most places, at $0.018 a year per $1,000 of building value ($0.030 typical). In Health Canada’s survey, 13% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Bedford grades B− for hazard risk, with wildfire counted against it.
What stands out about Bedford’s hazards
Four national sources, each read for Bedford: earthquakes, radon, past fires and flood studies.

Bedford grades B− for hazard risk
Seismic risk and radon set Bedford’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #47 of 88 in Nova Scotia and #1,724 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.
Wildfire is rare near Bedford: 2% of the land within 25 km burned since 1986, 1.2% within 5 km
Past fire around Bedford’s homes, from the national burned-area record, with the fuel within 5 km.
Next to the typical Canadian town (0.000% a year), Bedford’s 0.05% is in the low band.
Forest fuel covers 49% of the land close to Bedford and 77% across 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).
Burn rate a year, towns in Nova Scotia · highest of 90
In the upper half in Nova Scotia but far from Barrington (0.46%): Bedford ranks 26th of 90, at 0.05% a year.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
Some fire is mapped around Bedford, but not enough to leave the low band, where 92% of Canada’s 2,610 towns are; 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.

Towns with a flood study on file
Bedford is one of the 88% of towns in Nova Scotia with a flood study on file; across Canada it is 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Mapping around Bedford goes back to the 2010s and peaks in the 2020s, with 2 of its 3 studies.
Study dates as the NRCan inventory lists them, one count per study touching Bedford.
Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Bedford.
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.”

Ordinary seismic risk in Bedford: $0.018 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Nothing unusual about Bedford’s ground: $0.018 against a typical $0.030, 0.6 times.
Figures for earthquake risk are published for the city of Halifax as a whole, not for Bedford alone.

Test for radon in Bedford: 13% of area homes were over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Bedford’s area, at 13%, is above the 6.6% of the typical Canadian town, so testing is worth more here than most places.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Bedford’s area, at 13%, is close to the median in Nova Scotia (13%); 1% of its tests passed 600 Bq/m³.

One test in ten or more tops the guideline around Bedford, as in 22% of Canada’s 2,611 towns; 4.6% go higher.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
One home in Bedford can be high while next door is low; a three-month test settles it.

Get ready for what Bedford faces
Practical steps for Bedford’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
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Bedford is its health region’s, the survey’s design unit.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Bedford’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Bedford’s figure is its subdivision’s.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Bedford.
Questions about flooding and hazards in Bedford
How big is the earthquake risk in Bedford?
In NRCan’s seismic model, Bedford’s buildings lose $0.018 per $1,000 of value in an average year.
Is radon a problem in Bedford?
The area’s survey found 13% of 101 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Bedford.
Is Bedford at risk of wildfire?
Some, but Bedford’s low band (2% of nearby land burned since 1986, latest 2025) is short of the level that counts.
How is Bedford’s Hazard risk Grade worked out?
Bedford’s Hazard risk grade is B−, built on earthquakes and radon with a one-sided wildfire input.
Does Bedford flood?
There is flood mapping for Bedford on the national inventory, each study linked to its owner’s map, none of them graded.
