Wildfire barely registers for DT Fairview, at 0% of the land within 25 km since 1986 (0.000% a year). NRCan expects $0.040 of shaking damage a year per $1,000 of buildings in DT Fairview, near the typical $0.030. Radon is lower than usual: 0% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. DT Fairview grades A for hazard risk; wildfire is low here, so it earns no credit.
What stands out about DT Fairview’s hazards

Hazard risk in DT Fairview: A
Seismic risk and radon set DT Fairview’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #194 of 866 in Ontario and #529 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around DT Fairview has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where DT Fairview’s residents live, and the fuel next to their homes.
The yearly burn rate around DT Fairview is 0.000%, low beside 0.000% for the typical Canadian town.
Forest makes up 0.4% of the land within 5 km of DT Fairview and 0.5% within 25 km, little for a forest fire to run through.

Burn rate a year, towns in Ontario · highest of 871
Of the 871 towns in Ontario, 638 have a burn rate that rounds to zero, DT Fairview among them; Sioux Lookout leads at 0.16% 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.
92% of Canada’s 2,610 towns are in the low band and 7.5% above it; DT Fairview is among the many where the yearly burn rate rounds to zero.
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 is shown here, never graded: a study says where a map exists, not how many of DT Fairview’s homes stand in a flood zone.
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 DT Fairview faces
Practical steps for DT Fairview’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. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around DT Fairview until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for DT Fairview without grading them.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, DT Fairview’s included.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against DT Fairview.
Questions about flooding and hazards in DT Fairview
How big is the earthquake risk in DT Fairview?
