Spring Valley faces fewer hazards than 89% of Canadian towns
Around Spring Valley, wildfire is practically absent from the record: 0% within 25 km since 1986, 0.000% a year. Earthquake risk in Spring Valley is ordinary: NRCan’s model puts building losses at $0.030 a year per $1,000 of value, close to the typical town’s $0.030. In Health Canada’s survey, just 0% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Hazard risk gives Spring Valley a grade of A, from earthquakes and radon alone.

For Spring Valley, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Spring Valley faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Spring Valley grades A for hazard risk
Earthquake risk and radon make Spring Valley’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #105 of 866 in Ontario and #417 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.
Wildfire is rare near Spring Valley: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Spring Valley’s homes, from the national burned-area record, with the fuel within 5 km.
Next to the typical Canadian town (0.000% a year), Spring Valley’s 0.000% is in the low band.
Forest fuel rises from 0.2% within 5 km of Spring Valley to 5% within 25 km: the fuel lies away from homes.
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
Fire has taken almost none of the land around Spring Valley, as for 638 of the 871 towns in Ontario; Sioux Lookout tops the list at 0.16%.

Towns with a flood study on file
Flood maps are common in Ontario: 69% of towns have one, against 58% nationally, and Spring Valley is among them.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The 2000s brought the most flood studies for Spring Valley (3 of 4), the first dating from the 1990s.
Study dates as the NRCan inventory lists them, one count per study touching Spring Valley.
Flood is shown here, never graded: a study says where a map exists, not how many of Spring Valley’s homes stand in a flood zone.
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 Spring Valley: $0.030 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Spring Valley’s $0.030 is the typical figure ($0.030): ordinary ground for Canada.
Nobody publishes earthquake risk for Spring Valley alone, so this card uses the figure for the city of Brampton.
Shaking damage a year per $1,000 of building value
Below the middle in Ontario: Spring Valley’s $0.030 against a median of $0.043; Alexandria has $0.21.

Around half of Canada’s 2,611 towns expect more shaking damage than Spring Valley (48%).
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 Spring Valley is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Get ready for what Spring Valley faces
Practical steps for Spring Valley’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. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Spring Valley’s included.
- 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 Spring Valley until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Spring Valley without grading them.
- 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 Spring Valley.
