Little of the land around Mont-Tremblant has burned: 0% within 25 km since 1986, or 0.001% a year. Shaking is a bigger worry than in most places, at $0.065 a year per $1,000 of building value ($0.030 typical). More homes than usual carry radon here, 10% over the guideline where the typical town has 6.6%. Mont-Tremblant grades C for hazard risk; wildfire is low here, so it earns no credit.

Hazard risk in Mont-Tremblant: C
The grade weighs Mont-Tremblant’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #152 of 507 in Quebec and #2,099 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 78 homes were tested in the survey area, so the radon share is rough. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Few fires near Mont-Tremblant: 0.1% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Mont-Tremblant’s residents live, and the fuel next to their homes.
Around Mont-Tremblant fire takes 0.001% of the land in a typical year, the typical Canadian town 0.000%, which is low.
Near or far, forest fuel covers a similar share around Mont-Tremblant: 30% within 5 km and 32% within 25 km.
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
At 0.001% a year, Mont-Tremblant ranks 136th of the 513 towns in Quebec; Mistissini leads at 0.31%.
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.
Some fire is mapped around Mont-Tremblant, but not enough to leave the low band, where 92% of Canada’s 2,610 towns are; 7.5% rank higher.
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.

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.

Earthquakes cost buildings in Mont-Tremblant $0.065 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.
At $0.065 per $1,000, Mont-Tremblant carries roughly 2.2 times the typical Canadian town’s earthquake risk ($0.030).
Shaking damage a year per $1,000 of building value
Mont-Tremblant’s $0.065 sits under the median in Quebec, $0.14, and well under La Pocatière’s $0.48.

Get ready for what Mont-Tremblant faces
What to do about the hazards Mont-Tremblant 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
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Mont-Tremblant sits in.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Mont-Tremblant floods.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Mont-Tremblant’s included.
- 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 Mont-Tremblant.
