Fire has left almost no mark near Lumsden: 0% of the land within 25 km since 1986, 0.000% a year. Shaking is less of a worry than in most places, at $0.005 a year per $1,000 of building value ($0.030 typical). Lumsden grades B for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Lumsden’s hazards
Four national sources, each read for Lumsden: earthquakes, radon, past fires and flood studies.
What Lumsden faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Lumsden grades B for hazard risk
Two inputs always count for Lumsden, 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.
Wildfire is rare near Lumsden: 0% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Lumsden’s residents live, and the fuel next to their homes.
With 0.000% burned a year, Lumsden is among the many low-band places (the typical Canadian town 0.000%).
With 0% forest fuel within 5 km and 0% within 25 km, the land around Lumsden gives a fire little to burn.

Burn rate a year, towns in Saskatchewan · highest of 105
La Loche has the highest burn rate in Saskatchewan, 1.94% a year; around Lumsden, as around 55 of the 105 towns, it rounds to zero.
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.
92% of Canada’s 2,610 towns are in the low band and 7.5% above it; Lumsden is among the many where the yearly burn rate rounds to zero.
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.

A flood study covers Lumsden, from Water Security Agency: 1 on the inventory
Flood studies whose area touches Lumsden, from NRCan’s inventory, each linked to its owner.
For Lumsden the inventory points to Water Security Agency’s 1985 study, whose map is the one to check.

Towns with a flood study on file
Flood maps are thinner in Saskatchewan, 55% of towns against 58% nationally, but Lumsden has one.

Flood mapping is shown for Lumsden to be opened and checked, never turned into a grade.
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.”

Low seismic risk in Lumsden: $0.005 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Lumsden’s $0.005 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
About level with the typical town in Saskatchewan: Lumsden’s $0.005 against $0.006; Weyburn reaches $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.
Nearly every one of Canada’s 2,611 towns (96%) expects more shaking damage than Lumsden.
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).
The model counts damage to Lumsden’s buildings and their occupants from shaking only: not liquefaction, landslides, tsunami or fires after a quake.

25% of homes tested around Lumsden are over the radon guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline.
Lumsden’s area, at 25%, is above the 6.6% of the typical Canadian town, so testing is worth more here than most places.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
More homes top the guideline around Lumsden (25%) than in the typical town in Saskatchewan (9.1%); 4.3% went over 600.

Lumsden is in the 20–30% band, which holds only 3.1% of Canada’s 2,611 towns; 1.5% are higher.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
One home in Lumsden can be high while next door is low; a three-month test settles it.

| Regina Beach 1,322 · 18 km | Low | $0.007 | 25% | None listed |
The fire record around Lumsden No. 189 is a touch heavier than Lumsden’s, but the band is the same: low (here low).
Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Lumsden faces
What to do about the hazards Lumsden 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
- Wildfire counts one way. Wildfire is read from the national burned-area record around Lumsden’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Lumsden.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Lumsden is its health region’s, the survey’s design unit.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Lumsden’s figure is its subdivision’s.
