Fire has left almost no mark near Kennedy Park: 0% of the land within 25 km since 1986, 0.001% a year. For earthquakes Kennedy Park is middling, $0.043 a year per $1,000 against $0.030 for the typical town. Fewer homes than usual carry radon here, 2.7% over the guideline where the typical town has 6.6%. Kennedy Park grades A− for hazard risk, with wildfire counted against it.

Kennedy Park grades A− for hazard risk
For Kennedy 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: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The radon share rests on 74 home tests in the survey area, so a few homes move it. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near Kennedy Park: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Kennedy Park’s residents live, and the fuel next to their homes.
Around Kennedy Park fire takes 0.001% of the land in a typical year, the typical Canadian town 0.000%, which is low.
Nothing inside 5 km of Kennedy Park’s homes has burned since 1986, and the nearest scar is 17 km off.
Land that isn’t forest covers nearly all the ground around Kennedy Park: forest fuel is 0.3% within 5 km and 2.5% 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
Sioux Lookout burns fastest in Ontario at 0.16% a year; Kennedy Park, at 0.001%, ranks 83rd of 871.
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.
The low band takes in 92% of Canada’s 2,610 towns, Kennedy Park among them, though its rate is above zero; 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.

Toronto Regional Conservation Authority has mapped flooding for Kennedy Park (1 study)
Flood studies whose area touches Kennedy Park, from NRCan’s inventory, each linked to its owner.
For Kennedy Park the inventory points to Toronto Regional Conservation Authority’s 2021 study, whose map is the one to check.

Towns with a flood study on file
Mapping in Ontario reaches 69% of towns, Kennedy Park included, beside 58% across Canada.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood studies don’t enter the grade; they are listed so you can open the official map for Kennedy Park.
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.”

Expected shaking damage in Kennedy Park: $0.043 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.
Nothing unusual about Kennedy Park’s ground: $0.043 against a typical $0.030, 1.4 times.
For earthquake risk, the only official count covers all of the city of Toronto, Kennedy Park included.
Shaking damage a year per $1,000 of building value
Typical for its province: Kennedy Park at $0.043 beside a median in Ontario of $0.043, with Alexandria on top at $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: 36% of the 2,611 towns expect more damage than Kennedy 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).
The loss is to Kennedy Park’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

2.7% of homes tested around Kennedy Park are over the radon guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Measured across the City of Toronto Health Unit: radon tests
Kennedy Park’s area, at 2.7%, is below the 6.6% of the typical Canadian town, though any one home can still be high.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Fewer homes top the guideline around Kennedy Park (2.7%) than in the typical town in Ontario (4%).

Few tests over the guideline: Kennedy Park shares the bottom band with 37% of Canada’s 2,611 towns, below the other 63%.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
Basements, soil and how a house is sealed decide its radon, so in Kennedy Park only a test can say.

Get ready for what Kennedy Park faces
Practical steps for Kennedy 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. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Kennedy Park’s figure is its subdivision’s.
- 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 Kennedy Park.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Kennedy Park’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Kennedy Park takes its 2007 health region’s share.
Questions about flooding and hazards in Kennedy Park
How big is the earthquake risk in Kennedy Park?
About $0.043 a year per $1,000 of building value, NRCan’s long-run expectation for Kennedy Park.
How is Kennedy Park’s Hazard risk Grade worked out?
Kennedy Park’s Hazard risk grade is A−, built on earthquakes and radon with a one-sided wildfire input.
Does Kennedy Park flood?
The inventory lists a study touching Kennedy Park; whether a given street floods is on that map, not in the grade.
Is radon a problem in Kennedy 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 Kennedy Park.
Is Kennedy Park at risk of wildfire?
Some, but Kennedy Park’s low band (0% of nearby land burned since 1986, latest 2001) is short of the level that counts.
