No wildfire is mapped within 25 km of Vimont’s homes since 1986 (0% of the land, 0.000% a year). Seismic risk runs high: $0.21 of expected damage per $1,000 of buildings a year, the typical town $0.030. Radon is higher than usual: 12% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Vimont grades D for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Vimont’s hazards
Four national sources, each read for Vimont: earthquakes, radon, past fires and flood studies.

Vimont grades D for hazard risk
Earthquake risk and radon make Vimont’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #485 of 507 in Quebec and #2,507 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Vimont has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Vimont’s residents live, and the fuel next to their homes.
At 0.000% of the land a year, Vimont’s burn rate is in the low band; the typical Canadian town sees 0.000%.
Nothing inside 5 km of Vimont’s homes has burned since 1986, and the nearest scar is 7.3 km off.
Around Vimont the forest is thin or far off: 0.2% of the land within 5 km and 3.5% within 25 km is forest fuel.
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 Quebec · highest of 513
Mistissini has the highest burn rate in Quebec, 0.31% a year; around Vimont, as around 144 of the 513 towns, it rounds to zero.
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.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Vimont, at a rounded zero, is far from them.
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 Vimont
Flood studies whose area touches Vimont, from NRCan’s inventory, each linked to its owner.
NRCan’s inventory is silent on Vimont, so any flood map would be the municipality’s own.
Towns with a flood study on file
Flood maps are thinner in Quebec, 45% of towns against 58% nationally, and Vimont has none.
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 Vimont 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.”
Earthquakes cost buildings in Vimont $0.21 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Vimont’s $0.21 is about 6.9 times the typical town’s $0.030: it sits in one of Canada’s more active seismic zones.
Vimont doesn’t get its own earthquake risk figures; the ones here come from the city of Laval.
Shaking damage a year per $1,000 of building value
Earthquake risk in Quebec peaks in La Pocatière ($0.48); Vimont, at $0.21, sits above the median of $0.14.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Vimont is in the top tenth of Canada’s 2,611 towns for earthquake risk; 7.9% rank higher.

12% of homes tested around Vimont are over the radon guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Source area for radon tests: the Laval health region
Vimont’s survey area reads 12% over the guideline, well past the typical Canadian town’s 6.6%.
Tested homes over 200 Bq/m³
Over 600 Bq/m³

Vimont is in the 10–20% band, with 22% of Canada’s 2,611 towns; only 4.6% are higher.
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.
One home in Vimont can be high while next door is low; a three-month test settles it.

The fire record around Duvernay is a touch heavier than Vimont’s, but the band is the same: low (here low).
Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Vimont faces
Practical steps for Vimont’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.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
- Is earthquake cover included?
What this data can and can’t tell you
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Vimont’s.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Vimont is its health region’s, the survey’s design unit.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Vimont’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Vimont.
Questions about flooding and hazards in Vimont
Does Vimont flood?
No study on Canada’s Flood Map Inventory covers Vimont (0), which doesn’t mean it has never been mapped, so ask the municipality.
Is radon a problem in Vimont?
12% of the 107 homes Health Canada tested around Vimont topped the guideline; your own house needs its own test.
How is Vimont’s Hazard risk Grade worked out?
Vimont grades D for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
How big is the earthquake risk in Vimont?
Expected earthquake damage in Vimont comes to $0.21 a year for each $1,000 that buildings are worth.
Is Vimont at risk of wildfire?
Not much by Canadian standards: Vimont’s band is low, with 0% of the land within 25 km burned since 1986 (last in 2025), so wildfire doesn’t change its grade.
