Around Mount Pleasant, wildfire is practically absent from the record: 0% within 25 km since 1986, 0.000% a year. Shaking is about as much of a worry in Mount Pleasant as in most places, at $0.023 a year per $1,000 of building value ($0.030 typical). About as many homes carry radon around Mount Pleasant as elsewhere, 8.1% over the guideline where the typical town has 6.6%. Mount Pleasant grades B+ for hazard risk; wildfire is low here, so it earns no credit.

Mount Pleasant grades B+ for hazard risk
Two inputs always count for Mount Pleasant, earthquakes and radon; the third, wildfire, counts only against a town.

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
Mount Pleasant is one of the 46% of towns in Alberta with a flood study on file, fewer than Canada’s 58%.
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 Mount Pleasant.
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 Mount Pleasant faces
What to do about the hazards Mount Pleasant 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?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- 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 Mount Pleasant’s.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Mount Pleasant’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. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Mount Pleasant takes its 2007 health region’s share.
- 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 Mount Pleasant.
