A note before you read. This article is general consumer-information content covering Canadian residential radon mitigation pricing for 2026, drawn from publicly available CARST (Canadian Association of Radon Scientists and Technologists) industry guidance, Health Canada consumer materials, the C-NRPP-certified mitigation contractor base, and general Canadian industry observation. It is not a quote, an estimate, or a price guarantee. Actual quoted prices vary materially by region, contractor, building condition, foundation type, and material costs. Always obtain 2–3 written quotes from C-NRPP-certified Mitigation Professionals before committing to any specific mitigation work. This article is not legal, contracting, engineering, or warranty advice. We do not interpret your specific test result for you or recommend whether you should mitigate. Health Canada's residential radon guideline is 200 Bq/m³; the Canadian Cancer Society notes that no level of radon exposure is considered free of risk, and homeowners may choose to mitigate at any level. The decision is yours, informed by Health Canada's published guidance and a qualified C-NRPP-certified mitigation professional. See full disclaimers at the bottom.
If you have an elevated radon test result and you're researching what mitigation will actually cost in Canada, this article gives you the realistic picture. The headline number you'll see most quoted is $2,500–$4,500 for a standard sub-slab depressurization (SSD) system on a typical Canadian single-family home, drawn from CARST industry guidance and Health Canada consumer materials. That range is broadly accurate — but it's a starting point, not a final answer. Real-world Canadian mitigation quotes vary materially by province, building type, foundation condition, and a half-dozen other factors that we break down below.
This article gives you four things: (1) the realistic Canadian residential SSD cost range and what it actually buys, (2) what drives a higher or lower quote, (3) province-by-province pricing context, and (4) the financing programs and tax credits that may offset some of the cost. It is written to give you the price-transparency picture before you start collecting quotes — so you can recognize a reasonable quote from a poor one.
TL;DR for Canadian homeowners researching mitigation cost
- Typical Canadian SSD installation on a single-family home: $2,500–$4,500 all-in. Complex installations: $4,500–$7,500+ (multiple suction points, finished basements requiring extensive piping, crawlspace sub-membrane systems, slab-on-grade construction).
- Always use a C-NRPP-certified Mitigation Professional. Verify on the C-NRPP Find a Professional directory.
- Order an independent post-mitigation retest kit — $89 all-in →
- Financing and grants: Lungs Matter (national, up to $1,500), Saskatchewan Home Renovation Tax Credit (10.5% on up to $4,000–$5,000), Manitoba Hydro Energy Finance Plan (up to $5,000 financing), Tarion Ontario new-home warranty (up to $50,000 for qualifying new builds).

1. The headline: $2,500–$4,500 typical Canadian SSD cost
The widely-cited Canadian residential SSD mitigation cost range is $2,500–$4,500 all-in for a standard installation on a typical single-family home. This figure is consistent with:
- CARST industry guidance for member contractors.
- Health Canada consumer materials referencing typical residential mitigation costs.
- General Canadian industry observation across the C-NRPP-certified contractor base.
What "all-in" means for a fair quote in this range:
- Site assessment and system design.
- Materials (PVC piping, fan, sealing materials, manometer, electrical components).
- Labour for the installation (typically a one-day job for a standard home).
- Sealing of the sump cover, floor drains, and major slab penetrations.
- Exterior electrical disconnect for the fan, properly wired.
- Vent piping run from the suction point through the home and exiting above the roof line.
- A short-term post-installation verification reading by the contractor.
- Workmanship warranty.
Prices outside this range are not necessarily wrong — but they require explanation. A quote materially below $2,500 should raise questions about whether the contractor is C-NRPP-certified, whether the system design is appropriate for the home, and what's actually included. A quote materially above $4,500 may reflect legitimate complexity (multiple suction points, large or complex foundation, finished basement, crawlspace sub-membrane work, geographic premium for remote areas), or may reflect an unjustified premium that another C-NRPP-certified contractor would beat.
The single best price-discovery move is to get 2–3 written quotes from C-NRPP-certified contractors and compare what each includes.
2. What you're actually paying for
A typical Canadian residential SSD installation includes the following components and services. Understanding what's in each line item helps you compare quotes apples-to-apples.
2A. Design and assessment (typically $200–$500 of the total)
A C-NRPP-certified Mitigation Professional should assess your home before quoting — at minimum via detailed photos and floor plans, ideally on-site. The assessment determines:
- Foundation type (full basement, slab-on-grade, crawlspace, walk-out, mixed)
- Suction point location(s) — typically 1 for a standard single-family home, 2+ for larger or complex foundations
- Vent piping route through the home
- Fan size and location
- Sealing requirements (cracks, sump openings, slab penetrations)
- Electrical requirements
- Combustion-appliance safety considerations (gas furnace, water heater, fireplace)
A "fixed flat-rate quote without seeing your home" is a sign the contractor is selling a one-size-fits-all system rather than designing one for your house. Avoid.
2B. Materials (typically $500–$1,000 of the total)
- Inline radon fan: common Canadian-installed brands include RadonAway and Fantech, ranging roughly $200–$500 depending on size and efficiency tier (variable-speed ECM fans cost more upfront but are quieter and slightly more energy-efficient).
- PVC piping and fittings: 3–4 inch PVC, the run length depending on the routing through the home.
- Sealing materials: polyurethane sealants, sump covers, drain covers.
- Manometer: small U-tube pressure indicator on the vent pipe.
- Electrical components: disconnect switch, conduit, wiring.
2C. Labour (typically $1,200–$2,500 of the total)
A standard one-day installation involves:
- Drilling the suction point(s) through the basement slab (4–6 inch hole each).
- Installing the suction pipe and sealing around it.
- Routing the vent piping through the home to an exterior or attic location.
- Installing the fan in an unconditioned space.
- Routing the vent above the roof line, away from windows and air intakes per CARST setback requirements.
- Sealing major entry points (sump, drains, slab cracks).
- Installing the manometer.
- Wiring the fan to a properly installed exterior disconnect.
- Cleanup.
2D. Verification testing (typically $50–$150 of the total)
The contractor should run a short-term post-installation reading to verify the system is pulling negative pressure under the slab. This is the contractor's verification, not your independent confirmation — a separate independent long-term post-mitigation test by a third-party provider remains your responsibility (more on this in Section 9).
2E. Workmanship warranty (no direct cost line, built into pricing)
A reputable C-NRPP-certified contractor offers a workmanship warranty, typically:
- 5 years on workmanship and parts (varies by contractor).
- Manufacturer warranty on the fan (typically 5 years from major fan manufacturers).
- Written commitment to a post-mitigation level below 200 Bq/m³ within a specified period.
Get all warranty terms in writing. Verbal warranties are essentially worthless in a dispute.
3. What drives a higher quote
A quote above the typical $2,500–$4,500 range may reflect legitimate complexity. The most common drivers:
| Factor | Why it raises the price |
|---|---|
| Multiple suction points required | Larger foundations, complex layouts, or high initial radon levels may require 2+ suction points. Each adds materials and labour. |
| Slab-on-grade construction | No basement to work in; suction point placement and pipe routing more complex. |
| Finished basement | Pipe routing through finished spaces requires more careful work; may require some drywall opening and patching. |
| Crawlspace | Often requires sub-membrane depressurization (sealed plastic membrane over the crawlspace soil with an extraction fan) — significantly more labour-intensive than slab SSD. |
| Heritage / older home with hollow block foundation | May require block-wall depressurization in addition to or instead of SSD. |
| Long vent run / complex exterior routing | More piping, more difficult routing around HVAC, plumbing, electrical. |
| Combustion-appliance safety remediation | Gas furnace, water heater, or fireplace nearby may require combustion-safety testing and possibly worst-case depressurization assessment. |
| Geographic premium | Atlantic Canada, Northern Ontario, BC interior, the territories, and Northern Alberta have fewer C-NRPP-certified contractors and higher logistics costs. Quotes can be 25–50% higher for travel and supply-chain reasons. |
| Very high initial radon level | A home testing at 1,000+ Bq/m³ may need a higher-CFM fan and more aggressive sealing — material cost premium. |
| Heritage / large home | A 4,000+ sq ft home with multiple basement zones may require multiple systems. |
| Add-on diagnostics | Some contractors include pre- and post-mitigation diagnostic testing in their quote — adds value but also adds cost. |
If a higher quote is justified by these factors, the contractor should explain them clearly in writing. If a higher quote isn't tied to any of these factors and a comparable-spec quote from another C-NRPP contractor is materially lower, prefer the lower quote (assuming both meet the C-NRPP-certification, written-warranty, and post-mitigation-commitment requirements).
4. Red flags in pricing — what drives a suspicious low quote
A quote materially below $2,500 should raise questions. Common red flags:
- The contractor is not C-NRPP certified. This is the single biggest red flag. Health Canada's published consumer guidance is to use a C-NRPP-certified Mitigation Professional. Without certification, you have no third-party-verifiable credential, you may have insurance and warranty issues if anything goes wrong, and Tarion or other warranty providers may decline coverage if the work wasn't done by a certified professional.
- "Crack sealing only" pitch as a complete fix. Sealing cracks and sump openings is a supplement to active depressurization, not a substitute. A sealing-only "system" almost never reduces radon below 200 Bq/m³ in homes with elevated levels. Quotes around $500–$1,500 for "radon mitigation" are often sealing-only — that's not real mitigation.
- No on-site assessment. A flat-rate quote without seeing your home is a one-size-fits-all approach.
- No written commitment to a post-mitigation result below 200 Bq/m³.
- Refuses an independent post-mitigation test.
- Pressures you to sign immediately. Reputable mitigators do not high-pressure consumer sales.
- Asks for full payment upfront. Industry norm is a deposit (typically 25–50%) with the balance due on completion and successful post-mitigation verification.
- Cash-only / no written contract. Always get a written contract.
- Suggests skipping the post-mitigation test "to save money." That post-test is your verification — never skip it.
- Offers to tie the radon vent into your existing HVAC ductwork. This is incorrect practice and can spread radon throughout the home. Decline.
A "$1,500 guaranteed" quote from a non-C-NRPP-certified contractor is not actually cheaper than a $3,500 quote from a C-NRPP-certified contractor — it is a different product (an unverified system that may or may not work). The cheapest defensible Canadian mitigation is the lowest of 2–3 quotes from C-NRPP-certified contractors who all meet the design, warranty, and post-mitigation commitment requirements.

5. Province-by-province pricing context
The $2,500–$4,500 range is the Canadian residential SSD baseline. Provincial variation reflects local cost of living, contractor density, geographic logistics, and supply-chain factors. The notes below are general industry observation as of 2026 and are not quotes — always get 2–3 written quotes from C-NRPP-certified contractors in your specific area.
British Columbia
- Lower Mainland and Vancouver Island: generally aligns with the national $2,500–$4,500 range. Many C-NRPP-certified contractors based in Greater Vancouver and Victoria.
- BC Interior (Kamloops, Kelowna, Castlegar, Trail, Nelson, Prince George): higher prevalence regions, well-served by interior-based C-NRPP contractors, but Northern Interior (Prince George area) may have logistics premiums.
- Crawlspace mitigation common on Vancouver Island and parts of the Lower Mainland: sub-membrane depressurization can run $4,500–$7,500+ depending on size and accessibility.
Alberta
- Calgary, Edmonton, Airdrie, Red Deer corridor: strong C-NRPP-certified contractor base. Generally aligns with national range.
- Lethbridge, Medicine Hat: national range, occasional travel premium.
- Fort McMurray, Grande Prairie, northern Alberta: materially higher quotes due to logistics, contractor travel, and limited northern supply chain. Plan for the higher end of the range plus travel premiums.
Saskatchewan and Manitoba
- Regina, Saskatoon, Winnipeg, Brandon: provincial C-NRPP contractor base. Generally aligns with national range, sometimes slightly below in major centres due to active mitigation industry serving the high-prevalence prairie market.
- Northern Saskatchewan and Manitoba: travel premiums apply.
Ontario
- GTA, Hamilton, Niagara, Ottawa, Kingston, KW-Cambridge: high contractor density, competitive pricing, generally aligns with national range or slightly below at the low end.
- Northeastern Ontario (Sudbury, Sault Ste Marie, Thunder Bay, Timmins): higher prevalence regions and fewer local contractors. Some contractors travel from the GTA or southern Ontario; expect travel premiums of 10–25%.
- Tarion-eligible new builds: may have $0 cost to homeowner if the warranty claim is approved (see Section 6).
Quebec
- Montreal, Quebec City, Laval, Longueuil, Gatineau, Sherbrooke: provincial C-NRPP contractor base, generally aligns with national range.
- Outaouais (Gatineau region): can also be served by Ottawa-based C-NRPP contractors who cross the river — useful for price comparison.
- Saguenay-Lac-Saint-Jean, Mauricie, remote Quebec regions: travel premiums.
Atlantic Canada (NB, NS, PEI, NL)
- Halifax, Moncton, Saint John, Fredericton, Charlottetown, St. John's: materially fewer C-NRPP-certified contractors than central or western Canada. Quotes often 15–35% higher than national range due to logistics, contractor travel, and limited supply chain.
- Cape Breton, rural NB, rural NS, rural NL: travel premiums on top of the Atlantic premium.
- Ferry / island access (PEI, NL): additional logistics costs.
Territories (YT, NWT, NU)
- Whitehorse, Yellowknife: very few territorial-based C-NRPP-certified contractors. Most mitigation work is done by southern Canadian contractors who travel north or by northern BC/Alberta-based contractors who service the territories.
- Plan for the $2,500–$4,500 range plus material logistics and travel premiums — total quotes may run 50–100% above southern Canadian levels.
- Iqaluit and remote northern communities: case-by-case, often involving long-distance travel and shipping of materials. Get specific written quotes.
6. Financing and grants by region
Several Canadian programs may offset some or all of the mitigation cost. Verify each program directly before relying on it; programs change.
National
- Canadian Lung Association — Lungs Matter program: up to $1,500 toward radon mitigation for eligible Canadian homeowners. Eligibility, intake windows, and waitlists vary; verify directly at lung.ca.
Saskatchewan
- Home Renovation Tax Credit: non-refundable provincial tax credit equal to 10.5% of eligible renovation expenses on up to $4,000 (or $5,000 for seniors), per homeowner per year. Government of Saskatchewan and Health Canada guidance confirm radon mitigation generally qualifies. Verify at the Government of Saskatchewan Home Renovation Tax Credit page and consult a Saskatchewan tax professional before relying on this for tax planning.
Manitoba
- Manitoba Hydro Energy Finance Plan: financing of up to $5,000 for energy-related home improvements, generally including radon mitigation. Verify program scope, current interest rates, eligibility, and intake terms directly with Manitoba Hydro.
Ontario new-build owners (Tarion warranty)
- Tarion new-home warranty — radon coverage: up to $50,000 of mitigation coverage for qualifying new builds with an Agreement of Purchase and Sale signed on or after February 1, 2021, within a 7-year window from possession. Coverage is conditional on test type, test timing, professional qualifications, and other Tarion-specific rules. Meeting the qualification criteria does not guarantee a claim will be approved. See How to Claim the Tarion Radon Warranty in Ontario (Up to $50,000).
Other provinces
Other provinces do not currently offer province-specific radon-mitigation tax credits or financing programs equivalent to Saskatchewan's or Manitoba's at this time. Some provincial energy-retrofit programs occasionally include radon mitigation as an eligible measure — check your provincial energy-retrofit listings annually.
Stacking programs
In principle, the Lungs Matter grant (national) can be combined with provincial financing or tax credits, since each program has its own eligibility rules. Verify with each program administrator before assuming stacking is permitted.
7. Insurance considerations
A few insurance-adjacent points to consider:
- Mitigation work itself is generally not covered by home insurance as a "claim" (it's a preventive home improvement, not a sudden accidental event). However:
- The contractor's commercial general liability (CGL) insurance matters. Verify the contractor carries at least $2M in CGL coverage and ask for a current Certificate of Insurance. If the contractor damages your home during installation, their insurance is what covers it.
- Workers' Compensation / WSIB / WCB / CNESST coverage — if a worker is injured on your property and the contractor doesn't have provincial workers' compensation registration, you as the homeowner can be exposed. Ask for a clearance letter.
- For Tarion-eligible new builds in Ontario: the warranty may cover mitigation cost (see Section 6 above).
- Disclosure to home insurer: generally, completing a mitigation system is a positive risk signal to home insurers and does not increase premiums. Confirm with your insurer.
8. Hidden costs to watch for
The all-in $2,500–$4,500 range covers the standard installation, but there are some additional cost items that may or may not be included in a contractor's quote:
| Item | Typical cost | Usually included? |
|---|---|---|
| Permit (electrical or building) | $0–$200 depending on municipality | Sometimes included; confirm in writing |
| Drywall opening and patching (in finished basement) | $200–$800 depending on extent | Often NOT included; confirm |
| Independent post-mitigation long-term test | $89 (RadonTest.ca all-in) | NEVER included; this is a third-party test by design |
| Combustion-safety testing (if combustion appliances present) | $150–$400 | Sometimes included; confirm |
| Exterior aesthetic considerations (vent pipe routing aesthetics) | Variable | Discuss with contractor before installation |
| Removal of existing failed mitigation system | $200–$800 | Confirm before signing |
| Crawlspace prep (cleanup, vapor barrier, access remediation) | $300–$1,500 | Often NOT in standard quote; confirm for crawlspace systems |
| Operating cost (electricity) | $3–$8/month ongoing | N/A — homeowner cost |
The single most overlooked cost item is the independent post-mitigation test. The contractor's same-day verification is not a substitute. Budget $89 (or equivalent) for an independent long-term post-mitigation test from a provider not affiliated with the mitigation contractor.

9. The "all-in" question — what should be included in a quote
A defensible Canadian mitigation quote should include, in writing:
- C-NRPP Mitigation Professional certification number for the responsible professional.
- Current Certificate of Insurance (CGL ≥ $2M) and WCB/WSIB/CNESST clearance.
- Detailed system design (suction point locations, fan model, vent routing, sealing details, manometer placement, exterior disconnect).
- Reference to the CARST Canadian National Radon Mitigation Standard.
- Written performance commitment: the contractor commits to a post-mitigation result below 200 Bq/m³, and if the verified post-mitigation test exceeds 200 Bq/m³, the contractor will return at no additional cost to remediate.
- Workmanship warranty terms (duration, what's covered, what voids it).
- Permit responsibility (who pulls them, who pays).
- Total price, deposit, and balance terms — with a clear hold-back tied to successful post-mitigation verification where possible.
- Cancellation rights under your provincial consumer-protection law.
If the contractor's standard contract doesn't include these, request them in writing as a contract addendum. A serious mitigator will accommodate this.
10. Operating cost after installation
The mitigation fan runs continuously and uses approximately 30–90 watts depending on the fan model and size, costing roughly $3–$8 per month at typical Canadian provincial electricity rates. Annual operating cost: roughly $36–$96.
Variable-speed and ECM (electronically commutated motor) fans on the higher-efficiency end are slightly cheaper to operate and quieter. Standard AC inline fans are slightly cheaper upfront but use marginally more electricity.
This operating cost is permanent — the system runs continuously for as long as it's installed. Budget for it.
11. Long-term replacement costs
The vent piping and sealing typically last the life of the home and require no replacement.
The fan is the replaceable component:
- Typical fan lifespan: 5–10 years for major brands (RadonAway, Fantech, ECM models often longer).
- Replacement fan cost: roughly $200–$500 for the fan itself.
- Replacement labour: roughly $150–$400 (fan replacement is not complex; an electrician or HVAC technician can do it in 1–2 hours).
- Total replacement cost: roughly $350–$900 every 5–10 years.
Glance at the manometer monthly to confirm the system is operating. If the manometer indicator drops or the fan stops running (audible silence in the unconditioned space where the fan is located), schedule fan replacement.
12. FAQ — Canadian mitigation cost questions
What's the typical cost of radon mitigation in Canada? $2,500–$4,500 all-in for a standard sub-slab depressurization (SSD) system on a typical single-family home, drawn from CARST industry guidance and Health Canada consumer materials. Complex installations can run $4,500–$7,500+. Provincial variation applies.
Why does the price vary so much? The base price reflects standard SSD on a single-family home with full basement. Variation is driven by foundation type (slab-on-grade or crawlspace adds cost), home size and complexity (multiple suction points), finished basement (more piping and possible drywall work), geographic location (Atlantic Canada and the territories have higher logistics costs), and contractor experience. Always get 2–3 written quotes.
How much does a radon fan cost? The fan itself costs roughly $200–$500 at retail (RadonAway, Fantech are common Canadian-installed brands). Within an installed mitigation quote, the fan is bundled into the $2,500–$4,500 total.
How much does the mitigation fan cost to operate? Roughly $3–$8 per month in electricity at typical Canadian provincial rates (30–90 watts continuous). Annual: $36–$96.
Can I claim the mitigation cost on my taxes?
- Saskatchewan residents: generally yes, via the Saskatchewan Home Renovation Tax Credit (10.5% on up to $4,000, or $5,000 for seniors). Verify with a Saskatchewan tax professional.
- Other provinces: no province-specific radon-mitigation tax credit currently exists. Consult a tax professional.
Are there grants or financing programs available?
- Canadian Lung Association — Lungs Matter program: up to $1,500 for eligible Canadian homeowners (verify directly at lung.ca).
- Manitoba Hydro Energy Finance Plan: up to $5,000 in financing for energy-related home improvements including radon mitigation.
- Tarion Ontario new-home warranty: up to $50,000 for qualifying new builds with APS signed on or after February 1, 2021 (qualification rules apply; meeting qualification criteria does not guarantee claim approval).
Why is mitigation more expensive in Atlantic Canada and the territories? Fewer C-NRPP-certified contractors, higher contractor travel costs, longer logistics chains for materials. Expect quotes 15–50%+ above southern Canadian levels. Plan ahead for scheduling.
Is a "$1,500 guaranteed" mitigation a good deal? Almost certainly not. A quote materially below $2,500 typically reflects either a non-C-NRPP-certified contractor, a "crack sealing only" approach (which is not real mitigation), no on-site assessment, no written commitment to a post-mitigation result, or some combination. The cheapest defensible Canadian mitigation is the lowest of 2–3 quotes from C-NRPP-certified contractors meeting all the design, warranty, and post-mitigation requirements.
Should the post-mitigation test be included in the quote? The contractor's same-day short-term verification reading is typically included. Your independent long-term post-mitigation test (≥91 days, from a provider not affiliated with the mitigation contractor) is separate and budgets at $89 (RadonTest.ca all-in). This independence is the entire point of the verification step.
How long does mitigation take? Standard SSD installation on a Canadian single-family home is typically a one-day job. From decision to verified post-mitigation result usually takes 3–6 months including the 91+ day post-mitigation verification test.
How long does the system last? Vent piping and sealing typically last the life of the home. The fan typically lasts 5–10 years; replacement costs roughly $350–$900 every 5–10 years.
Will mitigation void my Tarion warranty in Ontario? Mitigation by a C-NRPP-certified professional, performed in compliance with applicable codes, generally should not void a Tarion warranty. For qualifying new builds, Tarion may even cover the mitigation itself (see Section 6). Always check your specific warranty documentation and consult Tarion before any major work.
Do I need to mitigate if I'm renting? Mitigation is the landlord's responsibility under most Canadian provincial residential tenancy frameworks. If you rent and your test came back high, document the result, share it with the landlord in writing, and request mitigation. See Radon for Canadian Renters (2026).
Should I get multiple quotes? Yes — get 2–3 written quotes from C-NRPP-certified contractors. Compare what each includes (design, warranty, post-mitigation commitment) — not just the headline price.
13. Order your retest kit
After your mitigation system is installed, the most important next step is an independent long-term post-mitigation test to verify it worked.

14. Important disclaimers
Not a quote, estimate, or price guarantee. This article is general consumer-information content. Cost ranges cited are typical Canadian residential pricing as of 2026 drawn from CARST industry guidance, Health Canada consumer materials, and general industry observation. Actual quoted prices vary materially by region, contractor, building condition, and material costs. Always obtain 2–3 written quotes from C-NRPP-certified Mitigation Professionals before committing to any specific mitigation work.
Not legal, contracting, engineering, or warranty advice. Always retain a qualified C-NRPP-certified mitigation professional for the design, installation, and verification of any radon mitigation system in your home, and consult a qualified tax professional or insurance broker for any specific financial decision.
No endorsement of any specific contractor. RadonTest.ca does not perform mitigation, recommend specific contractors, or warrant the work of any mitigator referenced or accessed via the C-NRPP directory or any other source mentioned in this article.
Cost ranges are typical, not guaranteed. The $2,500–$4,500 standard SSD range and $4,500–$7,500+ complex installation range reflect typical Canadian residential pricing as of 2026.
Mitigation reduction figures. Health Canada cites mitigation reductions of >80%; CARST data on properly designed SSD systems often shows reductions of 90–95%. Actual reduction depends on system design, building condition, and verification testing.
Tarion qualification hedge. References to Tarion warranty coverage are general. Tarion's coverage of radon mitigation depends on Agreement of Purchase and Sale date, test type, test timing, professional qualifications, and other Tarion-specific rules. Meeting the qualification criteria does not guarantee a claim will be approved. Always consult Tarion's current published rules and your specific warranty documentation.
Lungs Matter and provincial program eligibility. Eligibility for the Canadian Lung Association Lungs Matter program, Manitoba Hydro Energy Finance Plan, the Saskatchewan Home Renovation Tax Credit, and other provincial programs is determined by the program administrator, not by RadonTest.ca. Verify current eligibility directly with each program before relying on it.
No diagnosis or treatment claims. RadonTest.ca sells radon test kits. We do not diagnose, treat, or prevent disease.
