Fire seldom reaches Saint-Tite: since 1986, 0.1% of the land within 25 km has burned (0.003% a year). Seismic risk runs high: $0.095 of expected damage per $1,000 of buildings a year, the typical town $0.030. Radon is lower than usual: 0% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Saint-Tite a grade of A−; its wildfire band pulls it down.
What stands out about Saint-Tite’s hazards
For Saint-Tite, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Saint-Tite faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.
Wildfire
Earthquakes
Radon
Flood study
Hazard risk in Saint-Tite: A−
Earthquake risk and radon make Saint-Tite’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #20 of 507 in Quebec and #874 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 58 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 Saint-Tite: 0% within 5 km, 0.1% within 25 km
Fires mapped since 1986 around where Saint-Tite’s residents live, and the fuel next to their homes.
Low: the land around Saint-Tite burns at 0.003% a year, where the typical Canadian town sees 0.000%.
Near or far, forest fuel covers a similar share around Saint-Tite: 36% within 5 km and 40% within 25 km.

Burn rate a year, towns in Quebec · highest of 513
At 0.003% a year, Saint-Tite is near the top in Quebec: 32nd of 513, behind Mistissini (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.
Low, like 92% of the country’s 2,610 towns: the land around Saint-Tite burns, but slower than in the 7.5% above it.
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.

Gouvernement du Québec has mapped flooding for Saint-Tite (1 study)
Flood studies whose area touches Saint-Tite, from NRCan’s inventory, each linked to its owner.
A 2004 study by Gouvernement du Québec covers Saint-Tite, and its map, not the inventory, shows the zones.

Towns with a flood study on file
Mapping in Quebec reaches 45% of towns, Saint-Tite among them, below the 58% across Canada.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of Saint-Tite’s homes are at risk.
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.”

High seismic risk in Saint-Tite: $0.095 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Saint-Tite’s $0.095 is about 3.2 times the typical town’s $0.030: it sits in one of Canada’s more active seismic zones.
Shaking damage a year per $1,000 of building value
Saint-Tite’s $0.095 sits under the median in Quebec, $0.14, and well under La Pocatière’s $0.48.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
26% of Canada’s 2,611 towns expect more shaking damage than Saint-Tite, which places it in the upper third.

Get ready for what Saint-Tite faces
Practical steps for Saint-Tite’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
- 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 Saint-Tite.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Saint-Tite’s included.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Saint-Tite is its health region’s, the survey’s design unit.
- 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 Saint-Tite.
Questions about flooding and hazards in Saint-Tite
How is Saint-Tite’s Hazard risk Grade worked out?
Hazard risk gives Saint-Tite A−, weighing earthquakes and radon and counting wildfire only against it.
Is radon a problem in Saint-Tite?
0% of the 58 homes Health Canada tested around Saint-Tite topped the guideline; your own house needs its own test.
Does Saint-Tite flood?
There is flood mapping for Saint-Tite on the national inventory, each study linked to its owner’s map, none of them graded.
How big is the earthquake risk in Saint-Tite?
About $0.095 a year per $1,000 of building value, NRCan’s long-run expectation for Saint-Tite.
Is Saint-Tite at risk of wildfire?
Not much by Canadian standards: Saint-Tite’s band is low, with 0.1% of the land within 25 km burned since 1986 (last in 2023), so wildfire doesn’t change its grade.
