Around Regina, wildfire is practically absent from the record: 0% within 25 km since 1986, 0.000% a year. Earthquakes matter little: NRCan’s model puts building losses at $0.014 a year per $1,000 of value, against $0.030 for the typical town.
What stands out about Regina’s hazards
For Regina, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

No Hazard risk grade for Regina yet
Seismic risk and radon set Regina’s grade, wildfire can drag it down, and flood mapping stays out of it.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Little of the land around Regina has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Regina’s homes, from the national burned-area record, with the fuel within 5 km.
Regina burns at 0.000% a year, low against 0.000% for the typical Canadian town.
Land that isn’t forest covers nearly all the ground around Regina: forest fuel is 0% within 5 km and 0% within 25 km.

Towns with a flood study on file
Regina is one of the 55% of towns in Saskatchewan with a flood study on file, fewer than Canada’s 58%.

Flood mapping is shown for Regina 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 Regina: $0.014 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
At $0.014 per $1,000, Regina carries 0.5 times the typical Canadian town’s earthquake risk ($0.030): low.
Shaking damage a year per $1,000 of building value
Regina’s $0.014 tops the median in Saskatchewan, $0.006, though Weyburn reaches $0.033.

73% of Canada’s 2,611 towns expect more shaking damage than Regina.
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 Regina is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Radon runs high around Regina: 25% of tested homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
Regina’s area, at 25%, is above the 6.6% of the typical Canadian town, so testing is worth more here than most places. Regina doesn’t get its own radon tests figures; the ones here come from the Regina Qu'Appelle RHA.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Around Regina, 25% of tests were over 200 Bq/m³ and 4.3% over 600, against a median of 9.1% in Saskatchewan.

Few of Canada’s 2,611 towns (3.1%) share the 20–30% band with Regina, and 1.5% sit above it.
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.

Get ready for what Regina faces
Practical steps for Regina’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?
- 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. 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 Regina.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Regina’s included.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Regina takes its 2007 health region’s share.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Regina.
Questions about flooding and hazards in Regina
Is radon a problem in Regina?
25% of the 94 homes Health Canada tested around Regina topped the guideline; your own house needs its own test.
How is Regina’s Hazard risk Grade worked out?
When Canada’s grades arrive, Regina’s Risk will average earthquakes and radon and let wildfire only pull it down.
Does Regina flood?
The inventory lists a study touching Regina; whether a given street floods is on that map, not in the grade.
Is Regina at risk of wildfire?
The burned-area record shows next to nothing around Regina (0% within 25 km since 1986), so its band is low.
How big is the earthquake risk in Regina?
NRCan’s model expects shaking to cost buildings in Regina $0.014 a year for every $1,000 of their value, on average over many years.
