Wildfire isn’t Flemingdon Park’s worry: 0% of the land within 25 km burned since 1986 (0.001% a year). Seismic risk in Flemingdon Park sits near the middle: $0.043 of expected damage per $1,000 of buildings a year, the typical town $0.030. In Health Canada’s survey, just 2.7% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Hazard risk gives Flemingdon Park a grade of A−; its wildfire band pulls it down.
What stands out about Flemingdon Park’s hazards
Four national sources, each read for Flemingdon Park: earthquakes, radon, past fires and flood studies.

Each hazard against its own yardstick; meters run from low to high on that yardstick.

Flemingdon Park grades A− for hazard risk
For Flemingdon Park, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
Its place: #285 of 866 in Ontario and #700 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 74 homes were tested in the survey area, so the radon share is rough. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near Flemingdon Park: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Flemingdon Park’s residents live, and the fuel next to their homes.
The land within 25 km of Flemingdon Park burns at 0.001% a year on average, the low band; the typical Canadian town: 0.000%.
The 5 km ring around Flemingdon Park’s homes is clear of burns since 1986, the nearest 21 km out.
Little near Flemingdon Park’s homes can carry a forest fire; only 0.2% of the land within 5 km is forest fuel, and 1.6% within 25 km.

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.

Get ready for what Flemingdon Park faces
Practical steps for Flemingdon 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
- 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 Flemingdon Park until then.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Flemingdon Park’s.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Flemingdon Park without grading them.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Flemingdon Park’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
Questions about flooding and hazards in Flemingdon Park
How is Flemingdon Park’s Hazard risk Grade worked out?
Flemingdon Park grades A− for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
Does Flemingdon Park flood?
A flood study covers Flemingdon Park on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
How big is the earthquake risk in Flemingdon Park?
About $0.043 a year per $1,000 of building value, NRCan’s long-run expectation for Flemingdon Park.
Is radon a problem in Flemingdon Park?
The area’s survey found 2.7% of 74 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Flemingdon Park.
Is Flemingdon Park at risk of wildfire?
Some, but Flemingdon Park’s low band (0% of nearby land burned since 1986, latest 2001) is short of the level that counts.
