Hazard risk in Centre is lower than in 89% of Canadian towns
Fire has left almost no mark near Centre: 0% of the land within 25 km since 1986, 0.000% a year. For earthquakes Centre is middling, $0.030 a year per $1,000 against $0.030 for the typical town. Radon is lower than usual: 0% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Centre grades A for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Centre’s hazards
For Centre, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Centre faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Centre: A
Two inputs always count for Centre, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #105 of 866 in Ontario and #417 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.
Wildfire is rare near Centre: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Centre’s residents live, and the fuel next to their homes.
Low by Canadian standards: 0.000% of the land a year around Centre, 0.000% for the typical Canadian town.
Only 4.4% of the land within 25 km of Centre is forest fuel, and 0.1% close in.
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
Sioux Lookout has the highest burn rate in Ontario, 0.16% a year; around Centre, as around 638 of the 871 towns, it rounds to zero.
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%), Centre 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.

Flooding around Centre is mapped in 2 studies, the newest by Toronto Regional Conservation Authority
Flood studies whose area touches Centre, from NRCan’s inventory, each linked to its owner.
Toronto Regional Conservation Authority and others have studied flooding in areas that include Centre: 2 studies, the latest from 2021.
| Study | By | Year | Status |
|---|---|---|---|
| Toronto Floodline Consolidation | Toronto Regional Conservation Authority | 2021 | final |
| Fletcher's Creek | Credit Valley Conservation Authority | 2005 | final · not public |
Towns with a flood study on file
Its flood study puts Centre with 69% of towns in Ontario; Canada’s share is 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
No single decade dominates: 2 studies for Centre between the 2000s and the 2020s.
Study dates as the NRCan inventory lists them, one count per study touching Centre.
Flood is shown here, never graded: a study says where a map exists, not how many of Centre’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.”

Ordinary seismic risk in Centre: $0.030 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.030 per $1,000, Centre’s earthquake risk is the typical Canadian town’s $0.030.
Shaking damage a year per $1,000 of building value
Earthquake risk in Ontario peaks in Alexandria ($0.21); Centre, at $0.030, is below the median of $0.043.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Centre sits mid-range among Canada’s 2,611 towns: 48% expect more shaking damage.
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).
For Centre the model prices shaking damage to buildings, nothing more.

Get ready for what Centre faces
What to do about the hazards Centre 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
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Centre without grading them.
- 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 Centre.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Centre’s included.
- 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 Centre until then.
Questions about flooding and hazards in Centre
Is radon a problem in Centre?
In Health Canada’s survey, 0% of 90 homes tested in Centre’s area were above 200 Bq/m³, though only a test tells you about one house.
How big is the earthquake risk in Centre?
Expected earthquake damage in Centre comes to $0.030 a year for each $1,000 that buildings are worth.
Does Centre flood?
A flood study covers Centre on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
How is Centre’s Hazard risk Grade worked out?
Centre’s Hazard risk grade is A, built on earthquakes and radon with a one-sided wildfire input.
Is Centre at risk of wildfire?
Hardly at all on record: 0% of the land within 25 km of Centre since 1986, a low band, though small grass fires aren’t mapped.
