Little of the land around Grosvenor Park has burned: 0.6% within 25 km since 1986, or 0.02% a year. Seismic risk runs low: $0.006 of expected damage per $1,000 of buildings a year, the typical town $0.030. About as many homes carry radon around Grosvenor Park as elsewhere, 6.6% over the guideline where the typical town has 6.6%. Grosvenor Park grades A for hazard risk, with wildfire counted against it.

Grosvenor Park grades A for hazard risk
Two inputs always count for Grosvenor Park, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #9 of 104 in Saskatchewan and #299 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 76 homes were tested in the survey area, so the radon share is rough. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Grosvenor Park: 0.6% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Grosvenor Park’s residents live, and the fuel next to their homes.
The yearly burn rate around Grosvenor Park is 0.02%, low beside 0.000% for the typical Canadian town.
No fire has burned within 5 km of Grosvenor Park’s homes since 1986; the nearest burn is 21 km away.
Land that isn’t forest covers nearly all the ground around Grosvenor Park: forest fuel is 0% within 5 km and 0% 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).
Burn rate a year, towns in Saskatchewan · highest of 104
The land around Grosvenor Park burns at 0.02% a year, the 9th highest rate of 104 towns in Saskatchewan; La Loche tops it at 1.94%.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
Beside 2,610 Canadian towns, Grosvenor Park reads low, with 92% of them; only 7.5% rank higher.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Flood maps are thinner in Saskatchewan, 55% of towns against 58% nationally, but Grosvenor Park has one.
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 Grosvenor Park’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.”

Little shaking expected in Grosvenor Park: $0.006 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Grosvenor Park’s $0.006 is a fraction of the typical town’s $0.030 (0.2 times as much): quiet ground by Canadian standards.
Shaking damage a year per $1,000 of building value
Typical for its province: Grosvenor Park at $0.006 beside a median in Saskatchewan of $0.006, with Weyburn on top at $0.033.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Toward the quiet end of Canada’s range: 88% of its 2,611 towns sit above Grosvenor Park.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
Only shaking damage to buildings in Grosvenor Park is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Radon about average around Grosvenor Park: 6.6% over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline.
6.6% of tested homes around Grosvenor Park were over the guideline, much like the typical Canadian town at 6.6%. For radon tests, the only official count covers all of the Saskatoon RHA, Grosvenor Park included.

Get ready for what Grosvenor Park faces
What to do about the hazards Grosvenor Park 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. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Grosvenor Park’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 Grosvenor Park without grading them.
- 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 Grosvenor Park until then.
- Wildfire counts one way. For Grosvenor Park, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
