Wildfire isn’t Lord Roberts’ worry: 0% of the land within 25 km burned since 1986 (0.001% a year). Shaking is less of a worry than in most places, at $0.006 a year per $1,000 of building value ($0.030 typical). Lord Roberts grades B+ for hazard risk, with wildfire counted against it.
What stands out about Lord Roberts’s hazards
For Lord Roberts, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Hazard risk in Lord Roberts: B+
The grade weighs Lord Roberts’ seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
Its place: #10 of 185 in Manitoba and #940 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 66 homes were tested in the survey area, so the radon share is rough. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Few fires near Lord Roberts: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Lord Roberts’ residents live, and the fuel next to their homes.
With 0.001% burned a year, Lord Roberts is among the many low-band places (the typical Canadian town 0.000%).
Fire has stayed at least 23 km from Lord Roberts’ homes since 1986.
Forest fuel is scarce around Lord Roberts: 0% of the land within 5 km, 0% within 25 km.
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
At 0.001% a year, Lord Roberts is near the top in Manitoba: 31st of 189, behind Flin Flon (Part) (1.68%).
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.
Low, like 92% of the country’s 2,610 towns: the land around Lord Roberts burns, but slower than in the 7.5% 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.

The flood map inventory lists nothing for Lord Roberts
Flood studies whose area touches Lord Roberts, from NRCan’s inventory, each linked to its owner.
Canada’s Flood Map Inventory lists no study whose area touches Lord Roberts, which doesn’t mean it has never been mapped.
Towns with a flood study on file
No study touches Lord Roberts; in Manitoba, 18% of towns have one, below 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 Lord Roberts’ 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.”
Earthquakes cost buildings in Lord Roberts just $0.006 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Lord Roberts’ $0.006 is a fraction of the typical town’s $0.030 (0.2 times as much): quiet ground by Canadian standards.
Nobody publishes earthquake risk for Lord Roberts alone, so this card uses the figure for the city of Winnipeg.

Get ready for what Lord Roberts faces
What to do about the hazards Lord Roberts 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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- 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 Lord Roberts until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Lord Roberts without grading them.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Lord Roberts’ included.
- 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 Lord Roberts.
