Norway House 17 faces fewer hazards than 95% of Canadian towns
Wildfire is a moderate presence around Norway House 17: 3.5% of the land within 25 km has burned since 1986, 0.09% a year, short of the band that counts against Risk. Earthquakes matter little: NRCan’s model puts building losses at $0.004 a year per $1,000 of value, against $0.030 for the typical town. Radon around Norway House 17 is ordinary for Canada: 7.9% of tested homes over the guideline (6.6% typical). Hazard risk gives Norway House 17 a grade of A; its wildfire band pulls it down.

Hazard risk in Norway House 17: A
Seismic risk and radon set Norway House 17’s grade, wildfire can drag it down, and flood mapping stays out of it.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.

Towns with a flood study on file
Flood maps are thinner in Manitoba, 18% of towns against 58% nationally, and Norway House 17 has none.
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 Norway House 17’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 Norway House 17 faces
Practical steps for Norway House 17’s hazards, most pressing first.
- 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
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Norway House 17’s census subdivision (a neighbourhood shows its city’s).
- 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 Norway House 17 until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Norway House 17 without grading them.
- Wildfire counts one way. For Norway House 17, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
