A note before you read. This is general consumer information for Saskatchewan homeowners, buyers, sellers, landlords, and renters, drawn from publicly available Health Canada, Evict Radon / University of Calgary, Lung Saskatchewan, Government of Saskatchewan, and peer-reviewed sources. It is not medical, legal, or warranty advice. Radon results are reported against the Health Canada guideline of 200 Bq/m³; RadonTest.ca coordinates testing logistics and does not interpret individual results or provide health assessments.
Key facts: radon in Saskatchewan at a glance
- Saskatchewan has among the highest residential radon levels in Canada. Health Canada's 2012 survey found about 16% of SK homes above the 200 Bq/m³ guideline (up to 26% in some health regions); more recent work points even higher — Lung Saskatchewan, citing the 2024 Cross-Canada Radon Survey, says about 1 in 3 SK homes are above the guideline.
- Radon is the number one cause of lung cancer in non-smokers. A Saskatchewan Health Authority medical health officer has publicly estimated radon may be linked to at least 100 lung-cancer deaths a year in the province.
- The Health Canada guideline is 200 Bq/m³ (annual average). Above it, Health Canada recommends acting within one year — sooner the higher the level.
- Saskatchewan is the only province with a tax credit that covers radon mitigation. The Saskatchewan Home Renovation Tax Credit (re-introduced for 2025) lets homeowners claim radon work, and Lung Saskatchewan offers a mitigation reimbursement on top.
- But there's no warranty backstop. SK's new-home warranty is voluntary and does not cover radon. New homes must include a radon rough-in under the building code SK adopted in 2024 — though it's enforced locally, so coverage varies by municipality.
- A valid test takes at least 91 days. Fixing a home usually costs in the low thousands and installs in about a day.
- Any home can be high — even in low-prevalence pockets. The only way to know is to test.
How much radon is in Saskatchewan homes?
Radon is a naturally occurring radioactive gas — colourless, odourless, tasteless — produced as uranium in soil and rock breaks down, then seeping indoors. Saskatchewan's numbers are among the highest in the country.
- Health Canada's Cross-Canada Survey (2012) found about 16% of SK homes above the 200 Bq/m³ guideline — and up to 26% in the Regina-Qu'Appelle, Cypress, and Sunrise health regions. (For comparison, the national figure was about 7%.)
- More recent work points higher. Lung Saskatchewan, citing the 2024 Cross-Canada Radon Survey (the Evict Radon / University of Calgary study), states about 1 in 3 Saskatchewan homes are above the guideline. The 2024 survey reports the Prairie region (Alberta, Saskatchewan, Manitoba, and the NWT together) at about 1 in 5 homes, averaging roughly 114 Bq/m³ — among the highest of any region in Canada — and community testing in parts of SK has found even higher shares.
These figures come from different studies, years, and methods (a randomized federal survey versus newer, larger studies), so they aren't directly comparable — but they point the same way: Saskatchewan is a high-radon province. Health Canada uses "1 in 5" as its national headline; SK runs above it. (For the national picture, see radon levels by province.)
What this means for you: a provincial average can't tell you about your house. Two homes on the same street can read very differently depending on soil, foundation, and ventilation. A long-term test is the only way to know your own number.
Regina is the SK city that shows up most in the data: the 2024 survey lists it among Canadian municipalities where a quarter to half of homes are above the guideline, and a 2019 Regina study found about half of the homes tested were above 200 Bq/m³.

Why Saskatchewan has so much radon: the geology
It's tempting to blame Saskatchewan's famous uranium deposits — but those are in the Athabasca Basin in the far north, not under Regina or Saskatoon. The real driver of residential radon across the populated south is the soil. A University of Saskatchewan study found that radon emanation from prairie soils rises sharply with clay content, and that homes "built on soils with high clay content may be at greater risk of high radon levels, particularly when the soils are dry and cracked," which makes them more permeable to gas. Combine clay-rich, permeable prairie soils with tightly sealed homes during long, cold winters, and radon can accumulate. As Health Canada notes, radon is "usually higher in areas where there is a higher amount of uranium in underlying rock and soil" — and the southern prairie is one of those areas. As always, the picture varies house by house.
Is radon dangerous? The health risk in Saskatchewan
Radon is classified by the International Agency for Research on Cancer as a Group 1 carcinogen — the highest category, alongside tobacco smoke and asbestos. Health Canada's current figures:
- Radon is the number one cause of lung cancer in non-smokers, and the second leading cause overall after smoking.
- About 16% of lung-cancer deaths in Canada are estimated to be radon-related — more than 3,000 a year (Health Canada's fact sheet cites about 3,200).
- Health Canada estimates a non-smoker exposed to high radon over a lifetime has roughly a 1 in 20 chance of developing lung cancer from it; for a smoker, the combined risk rises to about 1 in 3.
For Saskatchewan specifically — a province Lung Saskatchewan calls a radon "hot spot" — a Saskatchewan Health Authority medical health officer has publicly estimated radon may be behind at least 100 lung-cancer deaths a year in the province. The risk is highest where radon is highest, but with one in three homes potentially above the guideline, it's province-wide.
Health Canada frames the risk proportionately, and so do we: there is no level of radon that is completely risk-free, the risk below the guideline is small, and it is ultimately each homeowner's choice what level of exposure they are willing to accept. Radon acts over the long term, with no immediate symptoms. The point isn't alarm — radon is measurable and fixable, and testing is inexpensive. (To separate fact from fiction, see our top radon misconceptions.)
The Health Canada guideline — and what your number means
Canada's guideline is 200 becquerels per cubic metre (Bq/m³), measured as an annual average in a normally occupied area of the home. It's a health-based guideline, not a hard legal limit for private homes. Health Canada's guidance:
- At or above 200 Bq/m³: take corrective action to reduce the level, within one year — and sooner the higher the result.
- Below 200 Bq/m³: no corrective action is recommended, though no level is risk-free; some households (especially where someone smokes) choose to act toward the WHO's more protective 100 Bq/m³ reference level.
Your result is a concentration, not a pass/fail — it sits on a spectrum. For what each range means and what Health Canada recommends at each, see how to read your radon test results and our comparison of the Health Canada, WHO, and US thresholds.
How to test for radon in Saskatchewan
With this much radon in the province, testing is essential — and it's straightforward:
- Use a long-term test of at least 91 days (three months). Radon swings day to day and season to season; a 91+ day average reflects your real exposure. Short-term tests are only for checking a mitigation system, never for deciding whether to act.
- The heating season (roughly October–April) is ideal, because Health Canada recommends that at least 91 days of the test fall within it; a test that runs largely outside the heating season can underestimate your annual average. You can start any time of year — just plan to run it long enough.
- Place the detector in the lowest lived-in level (often the basement if it's used), in a room occupied more than four hours a day, about 30 cm off the floor and away from drafts, vents, and direct sun. Not the kitchen, bathroom, or laundry room.
- Use a C-NRPP-approved test. RadonTest.ca kits use an alpha-track detector analysed by a C-NRPP-certified laboratory. (For how long-term kits compare with continuous digital monitors, see our guide.)
Where to get your test: order a RadonTest.ca kit — the detector, analysis by a C-NRPP-certified laboratory (with an all-in-Canada analysis option), tracked shipping both ways, and your result delivered with clear Health Canada context are all included. One caution about cheaper retail kits: not every hardware-store kit is analysed by a C-NRPP-certified lab — see our comparison of hardware-store radon test kits.
When to retest. Health Canada recommends testing again after any renovation that affects your home's structure or ventilation (a finished basement, new furnace, added bathroom), after energy retrofits (new windows, insulation, air sealing — which can raise radon by around 20% on average), or after excavation near the foundation. If you install a mitigation system, retest every five years to confirm it's still working. There's no blanket "every five years" rule for an unmitigated home — the trigger is change. (See when is radon testing season in Canada.)
If your radon is high: mitigation in Saskatchewan
A result above 200 Bq/m³ is a solvable problem (here's what to do if your radon is above 200 Bq/m³). Health Canada recommends hiring a C-NRPP-certified radon mitigation professional — and Saskatchewan, as a long-recognized high-radon province, has an established mitigation industry.
How it works. The standard, most effective method is active soil depressurization (ASD), also called sub-slab depressurization: a pipe through the foundation slab and a continuously running fan draw radon from beneath the home and vent it outside before it can enter your living space. In most homes this reduces radon by more than 80%, and a system often installs in about a day. A good contractor will run the fan continuously (never off), check that the system doesn't cause "back-drafting" of a furnace, water heater, or fireplace, and verify the work with a short-term test after activation plus a long-term test the following heating season — ideally not the company that installed it.
What it costs. Health Canada estimates $2,000–$3,000 for a typical sub-slab system, and national data from Take Action on Radon averages about $2,700 (complex buildings cost more); Lung Saskatchewan cites a typical SK range of roughly $2,500–$5,000. Running the fan adds roughly $50–$75 a year in electricity. The good news: Saskatchewan has more financial help for this than any other province (see below). (See radon mitigation cost in Canada.)
Find a certified professional. The Canadian National Radon Proficiency Program (C-NRPP) — run by the Canadian Association of Radon Scientists and Technologists with Health Canada oversight — certifies radon measurement professionals, mitigation professionals, and labs. Search the directory at c-nrpp.ca/find-a-professional. RadonTest.ca does not perform mitigation or recommend specific companies. (See also how to choose a licensed radon mitigator.)
Saskatchewan's radon rules and protections
Saskatchewan's distinctive feature is financial support, not regulation — its building and warranty rules are lighter than other provinces', but its money help is the best in the country.
Financial help: the best in Canada for radon
- Saskatchewan Home Renovation Tax Credit — the only provincial tax credit that covers radon mitigation. Saskatchewan was the first province to include radon mitigation in a renovation tax credit, and after the original 2020–2022 version ended, the province re-introduced the credit for 2025. It lets homeowners claim 10.5% on up to $4,000 of eligible renovation expenses (a saving of up to about $420), with seniors able to claim up to $5,000 (about $525) — and radon mitigation qualifies. (The original 2020–2022 credit was larger, at up to $20,000.) Confirm current details with the Government of Saskatchewan / CRA.
- Lung Saskatchewan "Caring Breaths" reimbursement. Lung Saskatchewan offers up to $500 toward radon mitigation by a C-NRPP-certified professional (up to $1,000 for those with a lung-cancer diagnosis). Check current availability, as the program periodically pauses and relaunches.
- Lungs Matter (Canadian Lung Association). A national grant of up to $1,500 toward mitigation, prioritizing people diagnosed with lung cancer and lower-income households.
Stacked together, these make Saskatchewan the province where fixing radon is least likely to come fully out of pocket.
New-home warranty: voluntary, and no radon coverage
Unlike Ontario, Alberta, BC, and Manitoba, a new-home warranty is voluntary in Saskatchewan — there's no law requiring it (though lenders and builder associations often do). The main provider is the Saskatchewan New Home Warranty Program. No SK warranty covers radon. This is a sharp contrast with Ontario, where the Tarion warranty explicitly covers radon mitigation up to $50,000 — so in Saskatchewan, fixing radon in a new home falls to the owner (helped by the tax credit and rebates above). (For the cross-country picture, see does your new home warranty cover radon?)
Building Code: a radon rough-in, but locally enforced
Saskatchewan adopted the 2020 National Construction Codes effective January 1, 2024, which require new small (Part 9) homes to include a radon rough-in — a sealed soil-gas barrier and a capped, labelled pipe under the slab, ready for a fan. The catch is enforcement: in Saskatchewan, building codes are administered locally, and a building permit is only required where a municipality has adopted a building bylaw and appointed a licensed building official. So whether the rough-in is actually inspected depends on where you build. It's a passive rough-in either way — a fan is added if a later test shows elevated radon — and the code requires no testing. (More detail: Canadian building codes and radon.)
Selling a home: disclosure in Saskatchewan
Saskatchewan's Property Condition Disclosure Statement is optional, not mandatory, and there's no radon-specific disclosure law. But Saskatchewan follows the general rule that while buyers beware of visible defects, a seller must disclose a known latent (hidden) defect — and a known, unmitigated high radon result is exactly that kind of hidden defect. So if you've tested and know your level is high, it should be disclosed; if you're buying, make radon part of your due diligence. (See radon when buying or selling a home in Canada.)
Workplaces and rentals
Saskatchewan's occupational health and safety rules set no binding radon limit for general workplaces — Lung Saskatchewan notes there is currently no regulation requiring SK workplaces to meet an acceptable radon level. Separately, federally regulated workplaces in SK (banks, telecom, interprovincial transport, federal operations) fall under the new federal rule SOR/2026-10, which sets a binding limit of 200 Bq/m³ (replacing the old 800 Bq/m³), coming into force around February 2027. For rental housing, see our guides for landlords and renters.
Frequently asked questions
What is a risk-free radon level in Saskatchewan? No level is completely risk-free. Health Canada's guideline is 200 Bq/m³, the level above which it recommends acting within a year. The risk below the guideline is small but not zero, and the WHO references a more protective 100 Bq/m³.
How common is high radon in Saskatchewan? Among the highest in Canada. Health Canada's 2012 survey found about 16% of SK homes above the guideline (up to 26% in some health regions); more recent work cited by Lung Saskatchewan points to about 1 in 3.
Is there money to help pay for radon mitigation in Saskatchewan? Yes — more than anywhere else in Canada. The Saskatchewan Home Renovation Tax Credit (re-introduced for 2025) covers radon mitigation, Lung Saskatchewan offers a reimbursement of up to $500 (up to $1,000 with a lung-cancer diagnosis), and the national Lungs Matter grant offers up to $1,500. Confirm current terms with each program.
Does Saskatchewan's new-home warranty cover radon? No. SK's new-home warranty is voluntary and does not cover radon — unlike Ontario's mandatory Tarion warranty.
Do I have to disclose radon when selling a home in Saskatchewan? There's no radon-specific disclosure law, and the property disclosure statement is optional — but a known, unmitigated high radon result is a latent defect a seller is generally expected to disclose.
Do new Saskatchewan homes have radon protection built in? The building code adopted in 2024 requires a radon rough-in in new homes, but it's enforced locally, so it depends on whether your municipality administers the building code. It's a passive rough-in; a fan is added if a test later shows elevated radon.
How long does a radon test take? At least 91 days (three months) for a valid long-term result. Short-term tests aren't suitable for deciding whether to act.
Test your Saskatchewan home
Saskatchewan has among the highest radon in the country — and, helpfully, the best financial support for fixing it. But the only way to know your home's level is a long-term test.
