On hazards, Nelson House 170 comes out behind 96% of Canadian towns
Wildfire is a real hazard for Nelson House 170: 14% of the land within 25 km has burned since 1986, 0.35% a year, in the high band. Shaking is less of a worry than in most places, at $0.004 a year per $1,000 of building value ($0.030 typical). About as many homes carry radon around Nelson House 170 as elsewhere, 7.9% over the guideline where the typical town has 6.6%. Hazard risk gives Nelson House 170 a grade of D−; its wildfire band pulls it down.

Hazard risk in Nelson House 170: D−
The grade weighs Nelson House 170’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.

Towns with a flood study on file
Mapping in Manitoba reaches 18% of towns, below the 58% across Canada, and not Nelson House 170.
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 Nelson House 170’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 Nelson House 170 faces
What to do about the hazards Nelson House 170 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
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Nelson House 170 is its health region’s, the survey’s design unit.
- 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 Nelson House 170’s.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Nelson House 170’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. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Nelson House 170.
