The national fire record shows next to nothing around Norton Park, 0% of the land within 25 km since 1986 (0.000% a year). For earthquakes Norton Park is middling, $0.030 a year per $1,000 against $0.030 for the typical town. Fewer homes than usual carry radon here, 0% over the guideline where the typical town has 6.6%. Hazard risk gives Norton Park a grade of A, from earthquakes and radon alone.

Hazard risk in Norton Park: A
For Norton Park, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
Its place: #105 of 866 in Ontario and #417 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.
Few fires near Norton Park: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Norton Park’s residents live, and the fuel next to their homes.
Norton Park burns at 0.000% a year, low against 0.000% for the typical Canadian town.
Forest makes up 0.1% of the land within 5 km of Norton Park and 3.3% within 25 km, little for a forest fire to run through.
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
Near-zero burning puts Norton Park with 638 of the 871 towns in Ontario, far below Sioux Lookout at 0.16%.
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.
Like most of Canada’s 2,610 towns (92%), Norton Park is in the low band, with a burn rate of zero to three decimals; 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.

Listed, not scored: a flood study proves a map exists, not that Norton Park floods.
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.

Expected shaking damage in Norton Park: $0.030 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Norton Park’s $0.030 is the typical figure ($0.030): ordinary ground for Canada.
Shaking damage a year per $1,000 of building value
Norton Park’s $0.030 sits under the median in Ontario, $0.043, and well under Alexandria’s $0.21.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Neither high nor low for Canada: 48% of the 2,611 towns expect more damage than Norton Park.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
Only shaking damage to buildings in Norton Park is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Get ready for what Norton Park faces
Practical steps for Norton Park’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. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Norton Park’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, Norton Park takes its 2007 health region’s share.
- Wildfire counts one way. For Norton Park, 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 Norton Park.
Questions about flooding and hazards in Norton Park
Is radon a problem in Norton Park?

How big is the earthquake risk in Norton Park?
Expected earthquake damage in Norton Park comes to $0.030 a year for each $1,000 that buildings are worth.
Is Norton Park at risk of wildfire?
