Hazards in Rossmere-A: wildfire low, radon over the guideline in 12% of tested homes
Wildfire isn’t Rossmere-A’s worry: 0% of the land within 25 km burned since 1986 (0.001% a year). Seismic risk runs low: $0.006 of expected damage per $1,000 of buildings a year, the typical town $0.030. Rossmere-A grades B+ for hazard risk, with wildfire counted against it.

Rossmere-A grades B+ for hazard risk
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like Rossmere-A with little fire nearby would get no credit for it.
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 Rossmere-A: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Rossmere-A’s residents live, and the fuel next to their homes.
The yearly burn rate around Rossmere-A is 0.001%, low beside 0.000% for the typical Canadian town.
Nothing inside 5 km of Rossmere-A’s homes has burned since 1986, and the nearest scar is 13 km off.
Land that isn’t forest covers nearly all the ground around Rossmere-A: forest fuel is 0% within 5 km and 0.1% within 25 km.

Burn rate a year, towns in Manitoba · highest of 189
The land around Rossmere-A burns at 0.001% a year, the 31st highest rate of 189 towns in Manitoba; Flin Flon (Part) tops it at 1.68%.

Low, like 92% of the country’s 2,610 towns: the land around Rossmere-A 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 Rossmere-A
Flood studies whose area touches Rossmere-A, from NRCan’s inventory, each linked to its owner.
An empty entry for Rossmere-A on the inventory isn’t proof of safety; ask locally for flood maps.
Towns with a flood study on file
No study touches Rossmere-A; in Manitoba, 18% of towns have one, below Canada’s 58%.

Listed, not scored: a flood study proves a map exists, not that Rossmere-A floods.
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.

Low seismic risk in Rossmere-A: $0.006 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
0.2 times the typical $0.030: Rossmere-A’s $0.006 is low for Canada.
Rossmere-A doesn’t get its own earthquake risk figures; the ones here come from the city of Winnipeg.

Rossmere-A’s area, at 12%, is above the 6.6% of the typical Canadian town, so testing is worth more here than most places.

Get ready for what Rossmere-A faces
What to do about the hazards Rossmere-A 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
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Rossmere-A’s included.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Rossmere-A floods.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Rossmere-A sits in.
- 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 Rossmere-A.
