With 0.53% of the land around it burning each year, St. Theresa Point sits in the high wildfire band (19% within 25 km since 1986). Shaking is less of a worry than in most places, at $0.003 a year per $1,000 of building value ($0.030 typical). In Health Canada’s survey, 7.9% of homes tested in St. Theresa Point’s area exceeded 200 Bq/m³, close to the typical 6.6%. St. Theresa Point grades D− for hazard risk, with wildfire counted against it.

St. Theresa Point grades D− for hazard risk
Two inputs always count for St. Theresa Point, earthquakes and radon; the third, wildfire, counts only against a town.
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.
27% of the land near St. Theresa Point’s homes has burned since 1986, 19% within 25 km
Fires mapped since 1986 around where St. Theresa Point’s residents live, and the fuel next to their homes.
High: the land around St. Theresa Point burns at 0.53% a year, where the typical Canadian town sees 0.000%.
Forest thickens with distance from St. Theresa Point: 71% of the land within 5 km, 79% within 25 km.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).

The flood map inventory lists nothing for St. Theresa Point
Flood studies whose area touches St. Theresa Point, from NRCan’s inventory, each linked to its owner.
Nationally, St. Theresa Point has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
No study touches St. Theresa Point; in Manitoba, 18% of towns have one, below Canada’s 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of St. Theresa Point’s homes are at risk.
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.”
Earthquakes cost buildings in St. Theresa Point just $0.003 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
0.1 times the typical $0.030: St. Theresa Point’s $0.003 is low for Canada.

Get ready for what St. Theresa Point faces
What to do about the hazards St. Theresa Point 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
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for St. Theresa Point’s census subdivision (a neighbourhood shows its city’s).
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for St. Theresa Point without grading them.
- Wildfire counts one way. For St. Theresa Point, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- 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 St. Theresa Point until then.
