Hazard risk in Fairview is lower than in 86% of Canadian towns
The burned-area map is nearly blank around Fairview, 0% within 25 km since 1986, 0.000% a year. NRCan expects $0.040 of shaking damage a year per $1,000 of buildings in Fairview, near the typical $0.030. In Health Canada’s survey, just 0% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Hazard risk gives Fairview a grade of A, from earthquakes and radon alone.

Fairview grades A for hazard risk
Seismic risk and radon set 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. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Fairview has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Fairview’s residents live, and the fuel next to their homes.
Fairview burns at 0.000% a year, low against 0.000% for the typical Canadian town.
Forest fuel is scarce around Fairview: 0.5% of the land within 5 km, 0.5% 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).
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, Fairview among them; Sioux Lookout leads at 0.16% a year.

Measured against 2,610 towns, Fairview is in the largest group, low (92%), and at its floor, while 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
Flood maps are common in Ontario: 69% of towns have one, against 58% nationally, and Fairview is among them.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of 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 Fairview faces
Practical steps for 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
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Fairview’s figure is its subdivision’s.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Fairview floods.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Fairview’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Fairview sits in.
