Hazard risk in L'Amoreaux West: A−
For L'Amoreaux West, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
Its place: #285 of 866 in Ontario and #700 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 74 homes were tested in the survey area, so the radon share is rough. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near L'Amoreaux West: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around L'Amoreaux West’s homes, from the national burned-area record, with the fuel within 5 km.

Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for L'Amoreaux West.
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.

Practical steps for L'Amoreaux West’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 L'Amoreaux West.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for L'Amoreaux West is its health region’s, the survey’s design unit.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of L'Amoreaux West’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 L'Amoreaux West’s.
