The burned-area map is nearly blank around Venise-en-Québec, 0% within 25 km since 1986, 0.000% a year. Earthquakes add more: NRCan’s model puts building losses at $0.15 a year per $1,000 of value, against $0.030 for the typical town. Radon is about average around Venise-en-Québec: 8.2% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Venise-en-Québec grades C for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Venise-en-Québec’s hazards
Four national sources, each read for Venise-en-Québec: earthquakes, radon, past fires and flood studies.
What Venise-en-Québec faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Venise-en-Québec: C
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Venise-en-Québec with little fire nearby would get no credit for it.
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.
Wildfire is rare near Venise-en-Québec: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Venise-en-Québec’s homes, from the national burned-area record, with the fuel within 5 km.
Forty years of fire maps put Venise-en-Québec at 0.000% a year, low next to the typical Canadian town’s 0.000%.
Fire has stayed at least 22 km from Venise-en-Québec’s homes since 1986.
Forest fuel is scarce around Venise-en-Québec: 2.3% of the land within 5 km, 4.1% within 25 km.

Venise-en-Québec is on the flood map inventory: 1 study, by Gouvernement du Québec
What Canada’s Flood Map Inventory lists for Venise-en-Québec: who studied flooding and where to see their maps.
One study on the inventory touches Venise-en-Québec, Gouvernement du Québec’s from 2004, and its area can be large, so it says a map exists, not that the town floods.

Towns with a flood study on file
Its flood study sets Venise-en-Québec apart in Quebec, where 45% of towns have one (Canada: 58%).

Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Venise-en-Québec.
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.”

Get ready for what Venise-en-Québec faces
What to do about the hazards Venise-en-Québec 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.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Check the address on the flood map.
- Are flood and wildfire insured?
- Is earthquake cover included?
What this data can and can’t tell you
- 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 Venise-en-Québec.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Venise-en-Québec’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Venise-en-Québec takes its 2007 health region’s share.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Venise-en-Québec’s figure is its subdivision’s.
