Sainte-Marcelline-de-Kildare grades B+ for hazard risk
Seismic risk and radon set Sainte-Marcelline-de-Kildare’s grade, wildfire can drag it down, and flood mapping stays out of it.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The radon share rests on 77 home tests in the survey area, so a few homes move it. The burned-area record misses fires under about 10 ha and most grass and farm fires.

Get ready for what Sainte-Marcelline-de-Kildare faces
Practical steps for Sainte-Marcelline-de-Kildare’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
- Wildfire counts one way. For Sainte-Marcelline-de-Kildare, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Sainte-Marcelline-de-Kildare’s census subdivision (a neighbourhood shows its city’s).
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Sainte-Marcelline-de-Kildare takes its 2007 health region’s share.
- 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 Sainte-Marcelline-de-Kildare.
Questions about flooding and hazards in Sainte-Marcelline-de-Kildare
How big is the earthquake risk in Sainte-Marcelline-de-Kildare?
