Al Ritchie grades C+ for hazard risk
Two inputs always count for Al Ritchie, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #74 of 104 in Saskatchewan and #2,005 of 2,589 Canadian towns.
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.
Little of the land around Al Ritchie has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Al Ritchie’s homes, from the national burned-area record, with the fuel within 5 km.
At 0.000% of the land a year, Al Ritchie’s burn rate is in the low band; the typical Canadian town sees 0.000%.
Only 0% of the land within 25 km of Al Ritchie is forest fuel, and 0.1% close in.

Towns with a flood study on file
Mapping in Saskatchewan reaches 55% of towns, Al Ritchie among them, below the 58% across Canada.
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 Al Ritchie.
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 Al Ritchie: $0.014 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Al Ritchie’s $0.014 is a fraction of the typical town’s $0.030 (0.5 times as much): quiet ground by Canadian standards.
Shaking damage a year per $1,000 of building value
Earthquake risk in Saskatchewan peaks in Weyburn ($0.033); Al Ritchie, at $0.014, sits above the median of $0.006.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
73% of Canada’s 2,611 towns expect more shaking damage than Al Ritchie.
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 Al Ritchie’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Test for radon in Al Ritchie: 25% of area homes were over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline. · Area-wide: radon tests, counted over the Regina Qu'Appelle RHA
Al Ritchie’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
Al Ritchie’s area, at 25%, is above the median in Saskatchewan (9.1%), and 4.3% of its tests passed 600 Bq/m³.

Al Ritchie 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.
Basements, soil and how a house is sealed decide its radon, so in Al Ritchie only a test can say.

Get ready for what Al Ritchie faces
What to do about the hazards Al Ritchie 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
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Al Ritchie 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 Al Ritchie.
- 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 Al Ritchie’s.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Al Ritchie’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
