The burned-area map is nearly blank around Deloraine-Winchester, 0% within 25 km since 1986, 0.000% a year. Earthquakes matter little: NRCan’s model puts building losses at $0.005 a year per $1,000 of value, against $0.030 for the typical town. Deloraine-Winchester grades B− for hazard risk; wildfire is low here, so it earns no credit.

Deloraine-Winchester grades B− for hazard risk
Seismic risk and radon set Deloraine-Winchester’s grade, wildfire can drag it down, and flood mapping stays out of it.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.

The flood map inventory lists nothing for Deloraine-Winchester
What Canada’s Flood Map Inventory lists for Deloraine-Winchester: who studied flooding and where to see their maps.
Nationally, Deloraine-Winchester has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Only 18% of towns in Manitoba have a flood study, short of Canada’s 58%, and Deloraine-Winchester is not among them.
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 Deloraine-Winchester’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.”

Get ready for what Deloraine-Winchester faces
Practical steps for Deloraine-Winchester’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
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Deloraine-Winchester without grading them.
- 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 Deloraine-Winchester.
- Radon is a survey. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around Deloraine-Winchester until then.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Deloraine-Winchester’s included.
