The burned-area map is nearly blank around Stanley Park, 0% within 25 km since 1986, 0.000% a year. For earthquakes Stanley Park is middling, $0.022 a year per $1,000 against $0.030 for the typical town. Radon is lower than usual: 4% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Stanley Park a grade of A−, from earthquakes and radon alone.
What stands out about Stanley Park’s hazards

Stanley Park grades A− for hazard risk
Two inputs always count for Stanley Park, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #237 of 866 in Ontario and #594 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.
Little of the land around Stanley Park has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Stanley Park’s homes, from the national burned-area record, with the fuel within 5 km.
Around Stanley Park fire takes 0.000% of the land in a typical year, the typical Canadian town 0.000%, which is low.
Only 4% of the land within 25 km of Stanley Park is forest fuel, and 1.3% 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
Of the 871 towns in Ontario, 638 have a burn rate that rounds to zero, Stanley Park among them; Sioux Lookout leads at 0.16% a year.
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 holds 92% of Canada’s 2,610 towns, and Stanley Park sits at its very bottom; only 7.5% are above it.
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.

Stanley Park is on the flood map inventory: 1 study, by Grand River Conservation Authority
What Canada’s Flood Map Inventory lists for Stanley Park: who studied flooding and where to see their maps.
One study on the inventory touches Stanley Park, Grand River Conservation Authority’s from 2018, and its area can be large, so it says a map exists, not that the town floods.
| Study | By | Year | Status |
|---|---|---|---|
| Grand River Regulatory Floodplain | Grand River Conservation Authority | 2018 | final |
Towns with a flood study on file
Flood maps are common in Ontario: 69% of towns have one, against 58% nationally, and Stanley Park is among them.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of Stanley Park’s homes are at risk.
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 Stanley Park: $0.022 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
At $0.022 per $1,000, Stanley Park’s earthquake risk is about the typical Canadian town’s ($0.030; 0.7 times).
Shaking damage a year per $1,000 of building value
Stanley Park’s $0.022 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: 61% of the 2,611 towns expect more damage than Stanley 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).

Get ready for what Stanley Park faces
What to do about the hazards Stanley Park 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 Stanley Park without grading them.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Stanley Park’s census subdivision (a neighbourhood shows its city’s).
- 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 Stanley Park until then.
- Wildfire counts one way. For Stanley 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.
Questions about flooding and hazards in Stanley Park
Does Stanley Park flood?
A flood study covers Stanley Park on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
How is Stanley Park’s Hazard risk Grade worked out?
Stanley Park’s Hazard risk grade is A−, built on earthquakes and radon with a one-sided wildfire input.
How big is the earthquake risk in Stanley Park?
NRCan’s model expects shaking to cost buildings in Stanley Park $0.022 a year for every $1,000 of their value, on average over many years.
Is Stanley Park at risk of wildfire?
Very little by the national record: Stanley Park’s band is low, with 0% of the land within 25 km burned since 1986, so wildfire doesn’t change its grade.
Is radon a problem in Stanley Park?
Around Stanley Park, 101 survey homes were tested and 4% came in over 200 Bq/m³, a guide to the area, not to any one home.
