Photo: Guerinf · CC0Saint-Lin--Laurentides’ hazards at a glance: a low wildfire record and 3.9% of area homes over the radon guideline
Fire seldom reaches Saint-Lin--Laurentides: since 1986, 0% of the land within 25 km has burned (0.001% a year). Seismic risk runs high: $0.16 of expected damage per $1,000 of buildings a year, the typical town $0.030. Hazard risk gives Saint-Lin--Laurentides a grade of B−, from earthquakes and radon alone.

Four national sources, each read for Saint-Lin--Laurentides: earthquakes, radon, past fires and flood studies.

Saint-Lin--Laurentides grades B− for hazard risk
Earthquake risk and radon make Saint-Lin--Laurentides’ grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #97 of 507 in Quebec and #1,722 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The radon share rests on 77 home tests in the survey area, so a few homes move it. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Saint-Lin--Laurentides has burned: 0% within 5 km, 0% within 25 km since 1986

The flood map inventory lists nothing for Saint-Lin--Laurentides
What Canada’s Flood Map Inventory lists for Saint-Lin--Laurentides: who studied flooding and where to see their maps.
Canada’s Flood Map Inventory lists no study whose area touches Saint-Lin--Laurentides, which doesn’t mean it has never been mapped.
Towns with a flood study on file
Flood maps are thinner in Quebec, 45% of towns against 58% nationally, and Saint-Lin--Laurentides has none.

Flood mapping is shown for Saint-Lin--Laurentides 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.”

Practical steps for Saint-Lin--Laurentides’ 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 Saint-Lin--Laurentides’.
- 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 Saint-Lin--Laurentides floods.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Saint-Lin--Laurentides’ homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Saint-Lin--Laurentides sits in.
Questions about flooding and hazards in Saint-Lin--Laurentides
Does Saint-Lin--Laurentides flood?
No study on Canada’s Flood Map Inventory covers Saint-Lin--Laurentides (0), which doesn’t mean it has never been mapped, so ask the municipality.

Hazard risk gives Saint-Lin--Laurentides B−, weighing earthquakes and radon and counting wildfire only against it.
Is radon a problem in Saint-Lin--Laurentides?
3.9% of the 77 homes Health Canada tested around Saint-Lin--Laurentides topped the guideline; your own house needs its own test.
