Since 1986 almost nothing has burned near Martensville: 0% of the land within 25 km, or 0.000% a year. Seismic risk runs low: $0.006 of expected damage per $1,000 of buildings a year, the typical town $0.030. Radon is about average around Martensville: 6.6% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Martensville grades A for hazard risk; wildfire is low here, so it earns no credit.

Hazard risk in Martensville: A
Two inputs always count for Martensville, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #5 of 104 in Saskatchewan and #291 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 76 homes were tested in the survey area, so the radon share is rough. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Martensville has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Martensville’s residents live, and the fuel next to their homes.
The yearly burn rate around Martensville is 0.000%, low beside 0.000% for the typical Canadian town.
Around Martensville the forest is thin or far off: 0% of the land within 5 km and 0% within 25 km is forest fuel.
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).

No flood study is listed for Martensville
Flood studies whose area touches Martensville, from NRCan’s inventory, each linked to its owner.
NRCan’s inventory is silent on Martensville, so any flood map would be the municipality’s own.
Towns with a flood study on file
Flood maps are thinner in Saskatchewan, 55% of towns against 58% nationally, and Martensville has none.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping is shown for Martensville 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 Martensville: $0.006 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.
0.2 times the typical $0.030: Martensville’s $0.006 is low for Canada.
Shaking damage a year per $1,000 of building value
Earthquake risk around Martensville ($0.006) matches the middle in Saskatchewan ($0.006), far from Weyburn’s $0.033.

Get ready for what Martensville faces
What to do about the hazards Martensville 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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Martensville’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Martensville.
- 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 Martensville’s.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Martensville is its health region’s, the survey’s design unit.
