A note before you read.

Quick answer. Saskatchewan has the highest provincial radon prevalence in Canada by Health Canada's national survey data — and Regina sits in the heart of that geology. Health Canada's Cross-Canada Radon Survey found roughly 1 in 5 Saskatchewan homes tested at or above the 200 Bq/m³ guideline. Every Regina home should be tested with a 3-month (≥91-day) long-term alpha-track test in the lowest lived-in level. If results exceed 200 Bq/m³, mitigation by a C-NRPP-certified contractor typically costs $2,500–$4,500, and Saskatchewan's Home Renovation Tax Credit (10.5% on up to $4,000, or up to $5,000 for seniors) generally covers radon mitigation as an eligible expense.

Why Regina Is a Radon Hotspot

Saskatchewan's geology — uranium-bearing shales and glacial till spread across the southern prairies — means radon-producing parent material is broadly distributed under most of the province. Regina sits on the Regina Plain, with foundation conditions, frost cycles, and prairie heating patterns that combine to push high concentrations of soil gas into homes during the long Saskatchewan heating season.

Three factors stack up:

  • Geology. Uranium-bearing parent material across the southern Saskatchewan plain produces radon as a natural decay product.
  • Stack effect. Long, cold winters mean Regina homes run furnaces continuously from October through April. Warm air rising up through the home creates negative pressure at the foundation, pulling soil gas — including radon — through cracks, sump openings, and slab penetrations.
  • Building stock. Many Regina homes have full basements that are used as bedrooms, rec rooms, home offices, and rental suites. That's exactly where radon concentrates.

The result: Saskatchewan has the highest provincial radon prevalence in Canada by Health Canada's national survey, and Regina is squarely within that hotspot zone.

What Regina-Area Data Shows

Health Canada's Cross-Canada Radon Survey reported Saskatchewan as the province with the highest proportion of homes at or above the 200 Bq/m³ residential guideline — roughly 1 in 5 (around 20%) of homes tested. That is materially higher than the Canadian national average of approximately 7%.

Regina-specific testing data from various sources (CARST member contractors, the University of Calgary's Evict Radon study where Saskatchewan participants are included, and the Lung Saskatchewan public testing program) consistently shows Regina-area test distributions skewed higher than the Canadian average.

Practical takeaway: in Regina, the question is not "am I one of the unlucky few?" but rather "have I confirmed that my specific home is one of the four-in-five that's below the guideline, or one of the one-in-five that's above?" The only way to answer is to test.

How to Test Your Regina Home

Health Canada's recommended test for residential decision-making is a long-term (≥91-day) alpha-track test, deployed in the lowest lived-in level of the home, ideally during the heating season (October–April) when stack effect is strongest.

For most Regina homes, the right test location is:

  • Finished basement if used as a bedroom, home office, gym, rec room, or rental suite
  • Lowest sleeping level if the basement is unfinished
  • Main floor only if the home has no basement

Place the kit at breathing height (roughly 1–2 metres off the floor), away from drafts, exterior walls, windows, and HVAC supply registers. Keep it in place for at least 91 days, then return it to the lab.

A long-term alpha-track test from a C-NRPP-recognized lab is the Health Canada standard for residential testing decisions. RadonTest.ca's $89 all-in long-term kit is designed and analyzed in Canada by a C-NRPP-recognized lab and ships across Saskatchewan with included return shipping.

Mitigation in Regina

If your test exceeds 200 Bq/m³, the standard fix is active sub-slab depressurization (ASD/SSD): a fan-powered system that pulls soil gas from beneath your basement slab and vents it above your roof.

For Regina homes, typical mitigation costs are $2,500–$4,500 for a standard SSD installation on a single-family home. Complex installations (multiple suction points, slab-on-grade construction, finished basements with extensive piping) can run higher.

Always use a C-NRPP-certified Mitigation Professional. Verify on the C-NRPP Find a Professional directory, filter by Saskatchewan.

For the full mitigator-selection playbook (questions to ask, red flags, contract checklist), see our How to Choose a Licensed Radon Mitigator in Canada guide.

After mitigation, run an independent post-mitigation test — ideally a 91+ day long-term test from a provider not affiliated with the mitigation contractor — to confirm levels are below 200 Bq/m³.

Saskatchewan Financing & Tax Credit

Saskatchewan offers two pieces of financial support that Regina homeowners should know about:

  • Saskatchewan Home Renovation Tax Credit. A non-refundable provincial tax credit equal to 10.5% of eligible renovation expenses on up to $4,000 in expenses (or up to $5,000 for seniors), per homeowner per year. Government of Saskatchewan and Health Canada guidance confirm that radon mitigation generally qualifies as an eligible renovation expense. Verify current program rules and eligibility at the Government of Saskatchewan Home Renovation Tax Credit page and consult a Saskatchewan tax professional before relying on this for tax planning.
  • Canadian Lung Association — Lungs Matter program. A national grant program offering up to $1,500 toward radon mitigation for eligible Canadian homeowners. Verify current eligibility and intake windows directly with the Lungs Matter program.

Combined, these can offset a meaningful share of mitigation cost for a Regina homeowner.

Real Estate & Disclosure in Saskatchewan

Saskatchewan real estate transactions involve a Property Condition Disclosure Statement (PCDS) that asks sellers about known material latent defects. Elevated radon — particularly when the seller has actual knowledge from a prior test — generally falls within the kind of material information that disclosure obligations may engage, depending on the specifics. Saskatchewan latent defect doctrine and case law govern the actual obligation; consult a Saskatchewan real estate lawyer for any specific transaction.

Buyers and sellers should both consider:

  • Buyers: if the home will be your primary residence, ask about prior radon testing during conditions period. If no test exists, weigh whether to make the offer conditional on a long-term test result. (Long-term tests don't fit a typical 10-day conditions window — the practical alternative is to negotiate a post-closing test holdback, with seller funding mitigation if results exceed 200 Bq/m³.)
  • Sellers: if you've already tested and know your levels are elevated, mitigate before listing — both for liability reasons and because mitigated, verified homes often transact more smoothly than untested ones.

Renters in Regina

Saskatchewan's Residential Tenancies Act generally requires landlords to maintain habitable rental units. Health Canada's residential radon guideline of 200 Bq/m³ informs what "habitable" means in the radon context.

If you rent in Regina (especially a basement suite — where radon concentrations are typically 2–3× higher than upper floors), you can:

  • Test the unit with a long-term alpha-track kit ($50–$100 all-in)
  • If results exceed 200 Bq/m³, share the lab report with your landlord in writing and ask them to mitigate
  • If the landlord refuses, options may include filing with the Office of Residential Tenancies (ORT) in Saskatchewan or seeking advice from a tenant advocacy line

Frequently Asked Questions

Is radon really worse in Regina than other Canadian cities? Yes — by available Health Canada survey data and Saskatchewan-specific testing data, Saskatchewan has the highest provincial radon prevalence in Canada, and Regina sits in the middle of that hotspot. Roughly 1 in 5 Saskatchewan homes tests above the 200 Bq/m³ Health Canada residential guideline, compared to a Canadian average closer to 7%.

What's the action level for radon in Regina? 200 Bq/m³ — the Health Canada residential guideline, which applies across all Canadian provinces including Saskatchewan.

How long does a radon test take in Regina? The Health Canada-recommended test is a 3-month (≥91-day) long-term alpha-track test, deployed in the lowest lived-in level of the home during the heating season (October–April).

How much does radon mitigation cost in Regina? Typical: $2,500–$4,500 for standard sub-slab depressurization (SSD) on a Regina single-family home. Complex installations can run $4,500–$7,500+. Get 2–3 written quotes from C-NRPP-certified contractors.

Does the Saskatchewan Home Renovation Tax Credit cover radon mitigation? Government of Saskatchewan and Health Canada guidance confirm that radon mitigation generally qualifies as an eligible expense for the Home Renovation Tax Credit (10.5% of up to $4,000, or up to $5,000 for seniors). Verify current program rules and consult a Saskatchewan tax professional before claiming.

Can I use the Lungs Matter grant in Regina? The Canadian Lung Association's Lungs Matter program offers up to $1,500 toward radon mitigation for eligible Canadian homeowners, including in Saskatchewan. Eligibility and intake vary; verify directly with the program.

Is there a Lung Saskatchewan program for radon? Lung Saskatchewan has historically run radon awareness and reduced-cost test kit programs in Saskatchewan. Program availability changes; verify directly with Lung Saskatchewan for current offerings.

Is the radon problem worse in older Regina homes or newer ones? Both can have elevated levels. Newer homes are sometimes more airtight (which can concentrate radon if soil-gas barriers and rough-ins weren't installed correctly); older homes often have more foundation entry points (cracks, sump openings, slab penetrations). The only way to know your specific home's level is to test.

Should I retest my Regina home after mitigation? Yes. Health Canada recommends retesting every 2 years after mitigation, or sooner after major renovations (basement finishing, foundation work, HVAC changes), to confirm the system continues to perform.

What if my landlord won't fix elevated radon in my Regina rental? Saskatchewan's Residential Tenancies Act generally requires habitable rental units. Document everything in writing, share lab reports, and if the landlord refuses to act, consider escalating to the Office of Residential Tenancies (ORT). Consult a Saskatchewan landlord-tenant lawyer for any specific situation.
