Wildfire isn’t Huron Heights’ worry: 0% of the land within 25 km burned since 1986 (0.000% a year). For earthquakes Huron Heights is middling, $0.020 a year per $1,000 against $0.030 for the typical town. In Health Canada’s survey, just 1.8% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Huron Heights grades A for hazard risk; wildfire is low here, so it earns no credit.

The flood map inventory lists nothing for Huron Heights
What Canada’s Flood Map Inventory lists for Huron Heights: who studied flooding and where to see their maps.
Nationally, Huron Heights has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file

NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Listed, not scored: a flood study proves a map exists, not that Huron Heights floods.
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.”

Get ready for what Huron Heights faces
Practical steps for Huron Heights’ 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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- 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 Huron Heights.
- 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 Huron Heights until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Huron Heights without grading them.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Huron Heights’ included.
