The national fire record shows next to nothing around Langham, 0% of the land within 25 km since 1986 (0.000% a year). Shaking is less of a worry than in most places, at $0.007 a year per $1,000 of building value ($0.030 typical). Radon around Langham is ordinary for Canada: 6.6% of tested homes over the guideline (6.6% typical). Langham grades A for hazard risk; wildfire is low here, so it earns no credit.

Langham grades A for hazard risk
Seismic risk and radon set Langham’s grade, wildfire can drag it down, and flood mapping stays out of it.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The radon share rests on 76 home tests in the survey area, so a few homes move it. The burned-area record misses fires under about 10 ha and most grass and farm fires.

At 0.000% of the land a year, Langham’s burn rate is in the low band; the typical Canadian town sees 0.000%.
Around Langham the forest is thin or far off: 0% of the land within 5 km and 0% within 25 km is forest fuel.

The flood map inventory lists nothing for Langham
What Canada’s Flood Map Inventory lists for Langham: who studied flooding and where to see their maps.
There is no study for Langham on the national flood inventory, which is far from complete.
Towns with a flood study on file
Mapping in Saskatchewan reaches 55% of towns, below the 58% across Canada, and not Langham.

Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Langham.
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 Langham just $0.007 per $1,000 a year

Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Langham faces
Practical steps for Langham’s hazards, most pressing first.
- 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
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Langham’s included.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Langham sits in.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Langham.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Langham floods.
Questions about flooding and hazards in Langham
How is Langham’s Hazard risk Grade worked out?
Hazard risk gives Langham A, weighing earthquakes and radon and counting wildfire only against it.
Is Langham at risk of wildfire?
The burned-area record shows next to nothing around Langham (0% within 25 km since 1986), so its band is low.
Does Langham flood?
No study on Canada’s Flood Map Inventory covers Langham (0), which doesn’t mean it has never been mapped, so ask the municipality.
Is radon a problem in Langham?
6.6% of the 76 homes Health Canada tested around Langham topped the guideline; your own house needs its own test.
How big is the earthquake risk in Langham?
NRCan’s model expects shaking to cost buildings in Langham $0.007 a year for every $1,000 of their value, on average over many years.
