Fire has left almost no mark near Wallace-Woodworth: 0% of the land within 25 km since 1986, 0.000% a year. Seismic risk runs low: $0.006 of expected damage per $1,000 of buildings a year, the typical town $0.030. Wallace-Woodworth grades C+ for hazard risk; wildfire is low here, so it earns no credit.

Hazard risk in Wallace-Woodworth: C+
The grade weighs Wallace-Woodworth’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #172 of 185 in Manitoba and #1,766 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Wallace-Woodworth: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Wallace-Woodworth’s homes, from the national burned-area record, with the fuel within 5 km.
Around Wallace-Woodworth fire takes 0.000% of the land in a typical year, the typical Canadian town 0.000%, which is low.
Forest makes up 0% of the land within 5 km of Wallace-Woodworth and 0% within 25 km, little for a forest fire to run through.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).
Burn rate a year, towns in Manitoba · highest of 189
Among the 189 towns in Manitoba, Flin Flon (Part) burns fastest (1.68% a year); Wallace-Woodworth is with the 60 near zero.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
The low band holds 92% of Canada’s 2,610 towns, and Wallace-Woodworth sits at its very bottom; only 7.5% are above it.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Towns with a flood study on file
Wallace-Woodworth is one of the 18% of towns in Manitoba with a flood study on file, fewer than 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 Wallace-Woodworth’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 Wallace-Woodworth faces
What to do about the hazards Wallace-Woodworth 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.
- 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. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Wallace-Woodworth.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Wallace-Woodworth’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Wallace-Woodworth, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Wallace-Woodworth takes its 2007 health region’s share.
