Wildfire isn’t White City’s worry: 0% of the land within 25 km burned since 1986 (0.000% a year). Seismic risk runs low: $0.012 of expected damage per $1,000 of buildings a year, the typical town $0.030. White City grades C+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about White City’s hazards
Four national sources, each read for White City: earthquakes, radon, past fires and flood studies.
What White City faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in White City: C+
Two inputs always count for White City, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #73 of 104 in Saskatchewan and #1,858 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near White City: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where White City’s residents live, and the fuel next to their homes.
A burn rate of 0.000% a year keeps White City in the low band (the typical Canadian town: 0.000%).
Land that isn’t forest covers nearly all the ground around White City: 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
Fire has taken almost none of the land around White City, as for 54 of the 104 towns in Saskatchewan; La Loche tops the list 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.
Measured against 2,610 towns, White City is in the largest group, low (92%), and at its floor, while 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.

Flooding around White City is mapped in 2 studies, the newest by Water Security Agency
Flood studies whose area touches White City, from NRCan’s inventory, each linked to its owner.
Water Security Agency and others have studied flooding in areas that include White City: 2 studies, the latest from 2025.
| Study | By | Year | Status |
|---|---|---|---|
| Regina Flood Mapping Study | Water Security Agency | 2025 | final |
| Regina | Water Security Agency | 2020 | under review · not public |
Towns with a flood study on file
White City is one of the 55% of towns in Saskatchewan with a flood study on file, fewer than Canada’s 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for White City.
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 White City just $0.012 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.
0.4 times the typical $0.030: White City’s $0.012 is low for Canada.
Shaking damage a year per $1,000 of building value
At $0.012, White City is above the typical town in Saskatchewan ($0.006); Weyburn has the most 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.
Most of Canada’s 2,611 towns (84%) face more earthquake damage than White City.
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 loss is to White City’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Test for radon in White City: 25% of area homes were over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Area-wide: radon tests, counted over the Regina Qu'Appelle RHA
the typical Canadian town has 6.6% over the guideline; White City’s area has 25%.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Radon runs higher around White City than in most towns in Saskatchewan: 25% over the guideline (9.1% is typical), 4.3% over 600.
Health Canada radon survey (2009–2011), by 2007 health region; medians of towns of 2,500 people or more.
One home in five or more tests over the guideline around White City; 3.1% of Canada’s 2,611 towns are in that band and 1.5% 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 White City can be high while next door is low; a three-month test settles it.

Get ready for what White City faces
What to do about the hazards White City 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
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for White City 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 White City until then.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of White City’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 White City’s.
Questions about flooding and hazards in White City
Does White City flood?
A flood study covers White City on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
Is White City at risk of wildfire?
Hardly at all on record: 0% of the land within 25 km of White City since 1986, a low band, though small grass fires aren’t mapped.
How big is the earthquake risk in White City?
About $0.012 a year per $1,000 of building value, NRCan’s long-run expectation for White City.
How is White City’s Hazard risk Grade worked out?
Hazard risk gives White City C+, weighing earthquakes and radon and counting wildfire only against it.
Is radon a problem in White City?
Around White City, 94 survey homes were tested and 25% came in over 200 Bq/m³, a guide to the area, not to any one home.
