Burn scars are few around Saint-Ulric, with 0% of the land within 25 km touched by fire since 1986 (0.000% a year). Earthquakes add more: NRCan’s model puts building losses at $0.081 a year per $1,000 of value, against $0.030 for the typical town. In Health Canada’s survey, 14% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Hazard risk gives Saint-Ulric a grade of D, from earthquakes and radon alone.
What stands out about Saint-Ulric’s hazards
Four national sources, each read for Saint-Ulric: earthquakes, radon, past fires and flood studies.
What Saint-Ulric faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Saint-Ulric grades D for hazard risk
The grade weighs Saint-Ulric’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
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.
Few fires near Saint-Ulric: 0.2% within 5 km, 0% within 25 km
Past fire around Saint-Ulric’s homes, from the national burned-area record, with the fuel within 5 km.
At 0.000% of the land a year, Saint-Ulric’s burn rate is in the low band; the typical Canadian town sees 0.000%.
Forest thickens with distance from Saint-Ulric: 46% of the land within 5 km, 62% within 25 km.

Burn rate a year, towns in Quebec · highest of 514
Near-zero burning puts Saint-Ulric with 145 of the 514 towns in Quebec, far below Mistissini at 0.31%.

92% of Canada’s 2,610 towns are in the low band and 7.5% above it; Saint-Ulric is among the many where the yearly burn rate rounds to zero.
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 Saint-Ulric
What Canada’s Flood Map Inventory lists for Saint-Ulric: who studied flooding and where to see their maps.
Nationally, Saint-Ulric has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Mapping in Quebec reaches 45% of towns, below the 58% across Canada, and not Saint-Ulric.
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 Saint-Ulric 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.”
High seismic risk in Saint-Ulric: $0.081 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
At $0.081 per $1,000, Saint-Ulric carries roughly 2.7 times the typical Canadian town’s earthquake risk ($0.030).
Shaking damage a year per $1,000 of building value
Below the middle in Quebec: Saint-Ulric’s $0.081 against a median of $0.14; La Pocatière has $0.48.

Saint-Ulric sits above most of Canada’s 2,611 towns on earthquake risk; 28% are higher.

14% of homes tested around Saint-Ulric are over the radon guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline. · Measured across the Bas-Saint-Laurent health region: radon tests
the typical Canadian town has 6.6% over the guideline; Saint-Ulric’s area has 14%.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
More homes top the guideline around Saint-Ulric (14%) than in the typical town in Quebec (8.2%); 1.8% went over 600.

One test in ten or more tops the guideline around Saint-Ulric, as in 22% of Canada’s 2,611 towns; 4.6% go 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.
Basements, soil and how a house is sealed decide its radon, so in Saint-Ulric only a test can say.

Get ready for what Saint-Ulric faces
What to do about the hazards Saint-Ulric 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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. Wildfire is read from the national burned-area record around Saint-Ulric’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Saint-Ulric.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Saint-Ulric takes its 2007 health region’s share.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Saint-Ulric’s figure is its subdivision’s.
