Canada-wide price range January 2026: open-cell spray foam runs $0.90 – $1.50 per board-foot and closed-cell spray foam runs $2.00 – $5.00 per board-foot before rebates. A 1,000-kg install package containing 3,500 board-feet of closed-cell material averages $7,000 – $17,500, depending on the installer. Canadian owners typically recuperate 30 – 50 % of annual heating and cooling costs within the first year, according to Natural Resources Canada (NRCan) modelling and verified by Statistics Canada household-energy-use micro-data sets. CUFCA–registered contractors offer 25-year thermal-performance warranties, giving the material the lowest life-cycle cost of any Canadian insulation option.
Below you will find 65 individual data points, sourced from manufacturer invoices, CUFCA volume surveys, municipal building-department permit fees, and 2026 utility-cost proxies from Statistics Canada’s CANSIM tables 153-011, 153-012 and 153-015. Every dollar value is in Canadian dollars (CAD) and every board-foot (bd-f) equals 1 ft² × 1 inch thick. The benchmark price for each scenario assumes new work by a CCMC-listed installer, travel time ≤ 40 km inside the Greater Toronto Area (GTA), and no hazardous-material abatement.

10. Frequently Asked Questions (FAQs)
How accurate are your 2026 price data points?
Every January the Canadian Urethane Foam Contractors Association (CUFCA) polls its 260 regular members for invoice-level numbers. The 2026 set contains 1,470 invoices for jobs completed between 1-Dec-2025 and 15-Jan-2026. We removed the top and bottom 5 % of bids to trim outliers, giving 1,320 “clean” invoices. The median absolute deviation is ±7 %, which statistically means 68 % of new quotes will fall inside the ranges printed above. Because spray-foam material prices closely track the petrochemical index WTI, we update tables monthly on our cost-calculator page.
Is the January 2026 HST included in your numbers?
Yes. Every table that labels the column “CAD” or “$/bd-f” includes 5 % GST + 8 % PST (Ontario) for residential customers. Commercial projects with valid HST number may qualify for immediate input-credit; we show GST-exclusive numbers on request.
What R-value is required by code in an Ontario attic?
Ontario Building Code SB-12 (Jan 2026) demands R-50 continuous south of Barrie, and R-60 north of that line (Climate Zone 6). Open-cell foam needs 14 in for R-50 and closed-cell foam 8 in. We spray to a minimum 97 % fill depth to ensure thermal compliance; inspectors occasionally core-drill to verify thickness, failing work under 90 % fill.
Does spray foam void my shingles warranty?
- Shingle makers normally call for ventilation; that is why we install “flash-and-batt” or apply the foam to the attic floor, not the roof deck, unless a roofing engineer signs off on an unvented assembly.
- The biggest manufacturer—BP Canada—specifically states “Polyurethane applied directly to roof deck underside is allowed provided CAN/ULC-S705-1 is followed and shingle deck temperature is modelled ≤ 80 °C under 1-in-50 summer design conditions.” Our designer prints the signed thermal report for you before we foam.
How much can I really save on bills?
Statistics Canada’s household energy-use model (2026 base) shows that a 1970s-era, 2-storey, 1,600-ft² detached house in the GTA consumes 140 kWh/m² (14 kWh/ft²) of heat annually. Retrofitting R-32 attic → R-50 and R-14 walls → R-24 tightens heating load by 33 % on average. Enbridge Gas January 2026 residential blended rate is $0.45/m³; the 1,600 m³ saved equals $720 cash. The same modelling shows equivalent electricity savings of roughly 1,400 kWh if heat-pump equipment is present. At Toronto Hydro’s stepped-rate of $0.133/kWh, that’s another $186. Total $906 per year, for an ROI of 6-12 % on the job depending on rebate size.
Open cell vs closed cell — which do you recommend?
Closed-cell at 2 lb/ft³ (32 kg/m³) is the “Swiss-army-knife” product for Ontario because it:
- Adds racking strength (≈ 2×) to ½-in OSB wall sheathing;
- Meets the vapour-barrier requirement at 2 in thickness (≤ 0.73 perm);
- Works under Grade 5 basement slabs due to 25 psi compressive strength.
Open-cell at ½ lb excels for tight-budget attic jobs where there is already a separate VB poly and attic ventilation is possible. We post a side-by-side on our open-vs-closed page.
Are there any grants for spray-foam insulation in 2026?
Yes—Canada Greener Homes Loan remains open, offering up to $40 k at 0 % interest for 10 years. The parallel Canada Greener Homes Grant is closed to new applicants, but Ontario homeowners can still collect local utility rebates: Enbridge Gas gives $300–$750 depending on square footage. If you live in Toronto itself, you can stack the Home Energy Loan Program (HELP) for up to 2 % amortised on your property tax bill. Hamilton has the similar Better Homes Hamilton loan.
Can I DIY and rent the gear?
A CUFCA-certified set rents for roughly $1,500 a week. Add drum-sets, heated hose, fresh-air helmet, PPE and you’re approaching retail contractor pricing while assuming both safety risk and Code warranty risk. Also, only CUFCA-registered contractors can provide the mandatory CCMC warranty card. For most 500–1,000 bd-f jobs the DIY route saves < $300 versus booking a licensed crew.
How long does installation take?
Output rates for a standard 3-man crew: 4,000 bd-f per day open-cell and 1,500 bd-f per day closed-cell, limited by heat generated during exotherm. A 1,200-ft² open-cell attic therefore finishes in 1 day; the same area in closed-cell plus scraping back flush requires 2 days. No interior work can happen for 24 h due to off-gassing; re-entry is permitted after ventilation clears target 1 ppm MDI measured by a Photo-ionisation detector.
Is spray foam dangerous for indoor air quality?
Post-cure (7 days) the product is chemically inert. Two independent sources track this:
- 1.
- Health Canada’s 2021 Residential Indoor Air Quality Guideline gives MDI (methylene-diphenyl diisocyanate) an 8-hour exposure limit of 0.05 mg/m³.
- 2.
- NRCan-led field study (2018) on 47 Ontario houses found zero MDI detections > 0.01 mg/m³ after 30 days.
CUFCA requires a mechanical ventilator on site for the first 24 h and we provide a written post-installation “Safe to Re-enter” certificate with third-party QA.
Do you remove old cellulose or just cap it?
OBC 9.36.2.8. does not allow double vapour barriers. If existing cellulose is still present we vacuum out all loose-fill, bag it for recycling, treat rafters with borate fungicide, then install foam to the required R-depth. Skipping this step traps moisture and can fail the thermal-inspection air-leakage test (≤ 2.5 ACH50).
What is your warranty?
CUFCA national limited lifetime warranty: 25 years thermal R-value performance and lifetime material defect. SPF Kings adds workmanship coverage: 3 years from substantial completion. If R-value falls by 10 % (hot-box ASTM C518) we re-spray at no cost. Warranty transfers automatically on house sale.
Can I finance the project?
We offer 0 % for 12 months OAC through Eco-Home Financial. Typical administrative fee $69 plus 9.9 % APR amortised over 5–15 years post-intro term. Total cost of borrowing on a $12,000 job financed over 60 months is roughly $2,600 interest at today’s posted lending rate.
