No wildfire is mapped within 25 km of Tiny’s homes since 1986 (0% of the land, 0.000% a year). Shaking is less of a worry than in most places, at $0.014 a year per $1,000 of building value ($0.030 typical). In Health Canada’s survey, just 0.9% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Tiny grades A+ for hazard risk, with wildfire counted against it.
What stands out about Tiny’s hazards
For Tiny, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Tiny faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Tiny: A+
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Tiny with little fire nearby would get no credit for it.
Its place: #5 of 866 in Ontario and #22 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 Tiny: 0% within 5 km, 0% within 25 km

At 0.000% of the land a year, Tiny’s burn rate is in the low band; the typical Canadian town sees 0.000%.
The nearer ring around Tiny is less wooded (13% forest fuel) than the land out to 25 km (22%).

Burn rate a year, towns in Ontario · highest of 871
Near-zero burning puts Tiny 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.
The low band holds 92% of Canada’s 2,610 towns, and Tiny 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.

No flood study is listed for Tiny
What Canada’s Flood Map Inventory lists for Tiny: who studied flooding and where to see their maps.
The inventory has nothing for Tiny, but a local or conservation-authority map may still exist.
Towns with a flood study on file
Flood maps are common in Ontario, 69% of towns against 58% nationally, but none in the inventory touches Tiny.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping is shown for Tiny to be opened and checked, never turned into a grade.
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.”
Little shaking expected in Tiny: $0.014 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Tiny’s $0.014 is a fraction of the typical town’s $0.030 (0.5 times as much): quiet ground by Canadian standards.
Shaking damage a year per $1,000 of building value
At $0.014, Tiny is below the typical town in Ontario ($0.043); Alexandria is highest at $0.21.

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 Tiny is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Radon runs low around Tiny: 0.9% of tested homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
A lower share than most: 0.9% of tested homes around Tiny, the typical Canadian town 6.6%. Tiny shares its radon tests numbers with the rest of the Simcoe Muskoka District Health Unit.

Fire is no heavier anywhere nearby than around Tiny (low), with Penetanguishene next at low.
Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Tiny faces
What to do about the hazards Tiny 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?
- Ask the municipality for flood maps.
- 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 Tiny’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Tiny, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Tiny takes its 2007 health region’s share.
- 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 Tiny.

Is Tiny at risk of wildfire?
No meaningful wildfire history near Tiny: 0% of nearby land since 1986, band low.
How big is the earthquake risk in Tiny?
