Burn scars are few around La Doré, with 0.7% of the land within 25 km touched by fire since 1986 (0.02% a year). Seismic risk runs high: $0.081 of expected damage per $1,000 of buildings a year, the typical town $0.030. Hazard risk gives La Doré a grade of B+; its wildfire band pulls it down.
What stands out about La Doré’s hazards
For La Doré, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

La Doré grades B+ for hazard risk
For La Doré, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 72 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.
Wildfire is rare near La Doré: 0.7% of the land within 25 km burned since 1986, 0% within 5 km

The flood map inventory lists nothing for La Doré
What Canada’s Flood Map Inventory lists for La Doré: who studied flooding and where to see their maps.
The inventory has nothing for La Doré, but a local or conservation-authority map may still exist.
Towns with a flood study on file
No study touches La Doré; in Quebec, 45% of towns have one, below Canada’s 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of La Doré’s homes stand in a flood zone.
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 La Doré $0.081 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.

Get ready for what La Doré faces
Practical steps for La Doré’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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, La Doré’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 La Doré.
- 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 La Doré floods.
- 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 La Doré sits in.
Questions about flooding and hazards in La Doré
How is La Doré’s Hazard risk Grade worked out?
Hazard risk gives La Doré B+, weighing earthquakes and radon and counting wildfire only against it.
Does La Doré flood?
No study on Canada’s Flood Map Inventory covers La Doré (0), which doesn’t mean it has never been mapped, so ask the municipality.
Is radon a problem in La Doré?
2.8% of the 72 homes Health Canada tested around La Doré topped the guideline; your own house needs its own test.
How big is the earthquake risk in La Doré?
In NRCan’s seismic model, La Doré’s buildings lose $0.081 per $1,000 of value in an average year.
Is La Doré at risk of wildfire?
Not much by Canadian standards: La Doré’s band is low, with 0.7% of the land within 25 km burned since 1986 (last in 2023), so wildfire doesn’t change its grade.
