Wildfire is rare near Division No. 7, Subdivision M: 0% of the land within 25 km has burned since 1986, a burn rate of 0.000% a year. Seismic risk runs low: $0.010 of expected damage per $1,000 of buildings a year, the typical town $0.030. Radon is lower than usual: 4% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Division No. 7, Subdivision M a grade of A, from earthquakes and radon alone.
What stands out about Division No. 7, Subdivision M’s hazards
Four national sources, each read for Division No. 7, Subdivision M: earthquakes, radon, past fires and flood studies.

Hazard risk in Division No. 7, Subdivision M: A
For Division No. 7, Subdivision M, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.

Flood is shown here, never graded: a study says where a map exists, not how many of Division No. 7, Subdivision M’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 Division No. 7, Subdivision M faces
Practical steps for Division No. 7, Subdivision M’s hazards, most pressing first.
- 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?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Division No. 7, Subdivision M without grading them.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Division No. 7, Subdivision M’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Division No. 7, Subdivision M until then.
- 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 Division No. 7, Subdivision M’s.
Questions about flooding and hazards in Division No. 7, Subdivision M
How is Division No. 7, Subdivision M’s Hazard risk Grade worked out?
Division No. 7, Subdivision M’s Hazard risk grade is A, built on earthquakes and radon with a one-sided wildfire input.
Is radon a problem in Division No. 7, Subdivision M?
4% of the 100 homes Health Canada tested around Division No. 7, Subdivision M topped the guideline; your own house needs its own test.
Does Division No. 7, Subdivision M flood?
A flood study covers Division No. 7, Subdivision M on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
