Some 1.7% of the land within 25 km of Grandview has burned since 1986; at 0.05% a year that is moderate, not high. Shaking is less of a worry than in most places, at $0.005 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Grandview a grade of B−; its wildfire band pulls it down.
What stands out about Grandview’s hazards
Four national sources, each read for Grandview: earthquakes, radon, past fires and flood studies.

Grandview grades B− for hazard risk
The grade weighs Grandview’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
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.
Some fire around Grandview: 1.7% of the land within 25 km since 1986, 0% within 5 km
Past fire around Grandview’s homes, from the national burned-area record, with the fuel within 5 km.
Moderate: the land around Grandview burns at 0.05% a year, where the typical Canadian town sees 0.000%.
No fire has burned within 5 km of Grandview’s homes since 1986; the nearest burn is 12 km away.
The forest starts beyond town: 0% of the land within 5 km of Grandview’s homes is forest fuel, against 5% within 25 km.

No flood study is listed for Grandview
What Canada’s Flood Map Inventory lists for Grandview: who studied flooding and where to see their maps.
There is no study for Grandview on the national flood inventory, which is far from complete.
Towns with a flood study on file
Only 18% of towns in Manitoba have a flood study, short of Canada’s 58%, and Grandview 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 studies don’t enter the grade; they are listed so you can open the official map for Grandview.
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.”
Little shaking expected in Grandview: $0.005 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Grandview’s $0.005 is a fraction of the typical town’s $0.030 (0.2 times as much): quiet ground by Canadian standards.
Shaking damage a year per $1,000 of building value
Earthquake risk around Grandview ($0.005) matches the middle in Manitoba ($0.006), far from Virden’s $0.007.

Get ready for what Grandview faces
What to do about the hazards Grandview faces, and what to ask before you buy.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- 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.
- Has it had a radon test?
- Ask the municipality for flood maps.
- How close is the forest edge?
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Grandview’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Grandview.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Grandview’s.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Grandview takes its 2007 health region’s share.
Questions about flooding and hazards in Grandview
Is radon a problem in Grandview?
In Health Canada’s survey, 43% of 122 homes tested in Grandview’s area were above 200 Bq/m³, though only a test tells you about one house.
