Spray Foam Rebates Ontario: Greener Homes, HER+ & OAIR

Ontario homeowners can reduce spray foam insulation costs by $1,250 to over $12,000 through stacked government rebates. The key is knowing which programs cover spray foam, how eligibility works for open-cell vs. closed-cell foam, and whether you can combine multiple programs on a single project. This guide covers every active rebate in the GTA — Canada Greener Homes, OAIR, HELP, and CMHC — with real cost examples and timeline breakdowns so you can make an informed decision before calling a contractor.

Canada Greener Homes Grant (CGHR) for Spray Foam

The Canada Greener Homes Grant is the federal government’s primary residential energy efficiency program — and it covers spray foam insulation as an eligible upgrade. Here’s what you need to know for a spray-foam project:

• Spray foam eligibility: Both open-cell (R-3.7/inch) and closed-cell (R-6/inch) spray foam qualify, as long as the post-retrofit attic reaches ≥R-22 or walls reach ≥R-12. Most GTA attic upgrades hit this easily at 3–5 inches of closed-cell.
• EnerGuide audit cost: $600–$1,200 CAD in the GTA. Required before and after the retrofit. SFK coordinates directly with NRCan-registered energy advisors — we refer you to advisors we’ve worked with in Toronto, Mississauga, and Markham.
• Audit timeline: Pre-audit typically scheduled 2–4 weeks out. Post-audit happens after installation. Total CGHR approval: 3–6 months from first audit to cheque.
• Spray foam coverage: Attic, basement/crawl space, and rim joist insulation all qualify as separate line items — maximizing your grant total.
• Greener Homes Loan: The $40,000 interest-free loan (separate from the grant) can fund your project while you wait for the grant reimbursement.

Our attic insulation service includes documentation support for CGHR claims — we photograph R-value measurements pre- and post-installation at no extra charge.

Enbridge Home Efficiency Rebate Plus (HER+) — Officially Closed

HER+ was Enbridge Gas’s flagship rebate — up to $5,000 for insulation and HVAC combined projects. It was the backbone of many spray foam stacking strategies until February 5, 2024, when Enbridge closed the program to new applicants.

If you completed spray foam work before that date and haven’t claimed, contact Enbridge directly — late submissions may still be processed. For new projects, the stacking strategy that was “CGHR $1,250 attic + HER+ $5,000 = $6,250 total” no longer applies. The updated best stack for GTA homeowners is OAIR $1,250 + CGHR up to $5,000 attic + CMHC refund — see the stacking section below.

IESO’s Save on Energy programs partially fill the gap for combined HVAC + insulation upgrades. Ask about current IESO eligibility when you book your spray foam assessment.

Ontario Attic Insulation Rebate (OAIR): Up to $1,250

OAIR is the fastest spray foam rebate available in Ontario — no EnerGuide audit required, approval in 2–4 weeks, and up to $1,250 CAD for qualifying attic insulation upgrades.

• Spray foam eligibility: Open-cell and closed-cell both qualify for attic applications. Must upgrade to minimum R-31 effective assembly — achieved with 5–6 inches of closed-cell at R-6/inch, or 8–9 inches of open-cell at R-3.7/inch.
• Application process: Submit contractor invoices and installation photos. SFK provides all documentation at project completion.
• Timeline: Apply within 60 days of installation. Rebate cheque arrives 2–4 weeks after approval.

Cost example: $5,200 attic spray foam project (1,200 sqft, open-cell). After OAIR $1,250 = $3,950 net cost. Combine with CGHR attic stream ($1,250–$2,000) and your net cost drops to $1,950–$2,700 on the same project.

Toronto Home Energy Loan Program (HELP): Up to $50,000

HELP is a City of Toronto initiative offering 0% interest loans up to $50,000, repaid through property taxes over 5 or 10 years. It’s uniquely suited to larger whole-home insulation projects in Toronto proper.

• Service areas: Toronto proper, Scarborough, North York, Etobicoke, East York. Does not cover Mississauga, Vaughan, Markham, or Brampton.
• Eligible measures: Attic, basement wall, crawl space, and rim joist spray foam; air sealing; window and door upgrades alongside insulation.
• Stacking: HELP can be used alongside CGHR and OAIR simultaneously. Use HELP to fund the full project, collect CGHR and OAIR rebates as reimbursement, then pay down the HELP loan early — effectively a $0-upfront retrofit.
• Application: No audit required. Apply online via the City of Toronto portal. SFK provides the required contractor quote documentation for approval.

A 2,000 sqft Toronto home needing full attic + basement spray foam: total project cost ~$14,000–$18,000. With HELP (full amount financed at 0%), CGHR ($3,000–$5,000 back), and OAIR ($1,250 attic), your out-of-pocket over 10 years could be as low as $7,750–$11,750 total — less than $1,000 per year.

See our Toronto spray foam page for city-specific project examples.

CMHC Green Home Premium Refund

If your home purchase was insured through CMHC and you subsequently perform qualifying energy upgrades, you’re eligible for a 25% refund on your mortgage insurance premium. For a $500,000 home with a 5% down payment, CMHC insurance is approximately $19,000 — a 25% refund returns roughly $4,750 CAD.

• Trigger: Achieve a minimum EnerGuide rating of 77 (for homes built before 2000) or demonstrate measurable improvement via a licensed energy advisor’s report.
• Spray foam’s role: Replacing aged attic insulation with closed-cell spray foam (R-6/inch) consistently lifts EnerGuide ratings by 8–15 points — often enough to trigger the 25% CMHC refund independently.
• Stack with CGHR: The same EnerGuide audit that unlocks your CGHR grant also generates the report CMHC needs. One audit fee, two payouts.

Can You Stack Multiple Rebates?

Yes — and stacking is where the real savings happen. Here are the two most effective combinations for spray foam projects:

Stack A: OAIR + CGHR (Attic Focus)

Best for: Attic-only spray foam projects, no audit pre-booked.

• OAIR attic rebate: $1,250 (apply first, 2–4 weeks)
• CGHR attic insulation stream: $1,250–$2,500 (requires EnerGuide)
• CMHC refund (if CMHC-insured mortgage): ~$3,000–$5,500
• Total: up to $9,250 on a single attic project

Stack B: HELP + CGHR + OAIR (Whole-Home, Toronto)

Best for: Toronto homeowners doing full attic + basement + rim joist spray foam.

• HELP loan covers 100% of project cost at 0%: up to $50,000
• CGHR grant (attic + basement streams): $3,000–$5,000
• OAIR attic component: $1,250
• Net result: project effectively funded at 0% with $4,250–$6,250 back in hand

Important: OAIR must not be double-claimed with a program that reimburses the identical measure. Our team confirms eligible combinations before any paperwork is submitted. Call 647-641-6881 for a no-cost stacking assessment.

Old insulation removal note: Pre-existing insulation removal qualifies as a preparatory eligible measure under CGHR, enabling full grant stacking even when removal adds $500–$1,500 to the project cost. SFK handles removal and re-insulation as a single project, simplifying CGHR documentation.

Spray Foam Costs Before & After Rebates (GTA Price Examples)

Cost by Foam Type (per sqft installed)

Real GTA Project Cost Examples (Before & After Rebates)

Downtown Toronto pricing carries a 10–15% premium over suburban GTA due to access complexity and urban logistics. Suburban areas (Vaughan, Markham, Brampton, Scarborough) typically see 5–10% savings vs. downtown rates.

Spray Foam vs. Fiberglass vs. Cellulose: Rebate & Performance Comparison

All three insulation types can qualify for some Ontario rebates — but spray foam earns the highest rebate totals due to combined air-sealing and thermal performance. Here’s a direct comparison:

Spray foam’s higher EnerGuide uplift directly increases CGHR grant totals and CMHC refund eligibility — making its higher upfront cost partially offset by larger rebate returns. Learn more on our spray foam insulation service page.

Ontario Building Code SB-12 & Spray Foam Compliance

Ontario Building Code Supplementary Standard SB-12 sets minimum effective thermal resistance values for new construction and major renovations. Closed-cell spray foam at R-6/inch exceeds SB-12 performance path requirements for attic (R-31 effective) and basement (R-12–R-20 depending on climate zone) across all GTA municipalities. Open-cell foam at R-3.7/inch meets SB-12 attic minimums at approximately 8–9 inches of depth.

SFK installs to SB-12 performance path by default. Every project includes a post-installation report confirming effective R-value and OBC compliance — documentation required for permit close-out and CGHR audit. Our basement insulation service includes this documentation as standard.

GTA Neighbourhood Spray Foam Pricing Breakdown

Spray foam pricing varies across the GTA based on access complexity, material logistics, and crew time. Here’s how the 10 SFK service areas compare:

• Downtown Toronto / Old Toronto: 10–15% premium over standard GTA. Narrow streets, older homes with complex attic geometry. Closed-cell attic: $3.50–$5.00/sqft.
• North York / Scarborough / Etobicoke: Standard pricing. Good access, typical 1960s–1980s bungalow and backsplit geometry. Closed-cell attic: $3.00–$4.50/sqft.
• Mississauga / Brampton: 5% below standard in newer subdivisions. Larger homes, higher total project cost but competitive per-sqft due to volume. See our Mississauga spray foam page for local examples.
• Vaughan / Thornhill / Markham: Standard. Newer builds typically have larger attics (1,500–2,000 sqft). Open-cell attic: $1.80–$2.50/sqft installed. See our Thornhill spray foam page for neighbourhood specifics.

Why Choose Spray Foam Kings for Your Rebate Project?

We’ve completed hundreds of spray foam projects across the GTA with rebate assistance built into every job — not as an afterthought. Here’s what that means in practice:

• Rebate paperwork handled for you: We prepare contractor documentation, installation photos, R-value reports, and invoice formatting required by CGHR, OAIR, and HELP. You submit; we back you up.
• EnerGuide referral network: We work with NRCan-registered energy advisors in Toronto, Mississauga, and Markham. No cold calls, no long waits.
• SPFA certified + $5M liability + WSIB: All certifications required for CGHR and HELP contractor eligibility. No surprises at audit time.
• 15+ years in GTA: We know which homes in North York have accessible attic hatches, which Brampton basements need a vapour barrier exception, and which Toronto renovation permits require insulation upgrades.
• No-audit OAIR fast-track: For attic jobs with tight timelines, we prioritize OAIR documentation so you receive the $1,250 rebate within 2–4 weeks of installation — no energy advisor booking required.

“We had no idea we qualified for three different rebate programs until SFK walked us through it. They handled all the paperwork for CGHR and OAIR — we got $3,750 back on a $7,800 attic project. The team was professional, fast, and the house is noticeably warmer.”

Frequently Asked Questions

Does closed-cell spray foam qualify for the Canada Greener Homes Grant?

Yes. Closed-cell spray foam at R-6/inch qualifies for all streams of the Canada Greener Homes Grant — attic (must reach ≥R-22 total), basement walls (≥R-12), and rim joist. The pre- and post-retrofit EnerGuide audit confirms the upgrade meets NRCan’s performance thresholds. Most closed-cell attic jobs at 3.5–4 inches easily surpass the R-22 minimum.

Does open-cell spray foam qualify for CGHR and OAIR?

Yes. Open-cell foam at R-3.7/inch qualifies for both CGHR and OAIR, provided the total post-retrofit R-value meets the program minimum. For an attic job, 6–7 inches of open-cell reaches R-22–R-26, satisfying both programs. Open-cell costs $1.50–$3.50/sqft installed — more cost-effective for vented attics where a Class II vapour barrier isn’t required.

Is the Enbridge HER+ rebate still available?

No. Enbridge closed the Home Efficiency Rebate Plus (HER+) program to new applicants on February 5, 2024. If your spray foam work was completed before that date and you haven’t filed, contact Enbridge Gas directly — late claims may still be processed. For new projects, use the OAIR + CGHR stacking strategy described in this guide.

How long does it take to receive a CGHR grant payment?

The full CGHR timeline from first EnerGuide audit to cheque receipt is typically 3–6 months: pre-audit booking 2–4 weeks, installation, post-audit 2–4 weeks, NRCan processing 6–12 weeks. The Greener Homes Loan (up to $40,000 at 0% interest) processes faster at 4–8 weeks and can fund your project while you await the grant.

How much does an EnerGuide audit cost in the GTA?

EnerGuide audits cost $600–$1,200 CAD in the GTA. A typical 1,500–2,500 sqft detached home costs $700–$900 per audit. CGHR reimburses up to $600 of audit costs as part of the grant, partially offsetting the expense. Pre- and post-installation audits are separate fees.

Can I stack OAIR with Canada Greener Homes on the same attic project?

Yes, and this is the recommended strategy for attic-only projects. OAIR pays $1,250 with no audit requirement in 2–4 weeks. CGHR pays an additional $1,250–$2,500 for the attic insulation stream after EnerGuide confirmation. Submit OAIR immediately after installation; book the CGHR audit simultaneously. Total combined rebate: $2,500–$3,750 on a single attic project.

Does old insulation removal qualify for any rebate?

Old insulation removal qualifies as an eligible preparatory measure under CGHR when required for the new installation. The removal cost can be included in your total project cost used to calculate grant percentages. SFK handles removal and re-insulation as a single project on your invoice, simplifying the CGHR documentation package.

What is the Toronto HELP program and how does it work for spray foam?

The Toronto Home Energy Loan Program (HELP) provides 0% interest loans up to $50,000 to Toronto homeowners for energy efficiency upgrades, repaid through property taxes over 5 or 10 years. Spray foam insulation is a fully eligible measure. SFK provides the contractor documentation required for HELP applications. HELP can be stacked with CGHR and OAIR simultaneously.

Do I apply for rebates before or after the spray foam work is done?

It depends on the program. For CGHR, you must book your pre-retrofit EnerGuide audit before installation begins — this is mandatory. For OAIR, application occurs after installation (within 60 days). For HELP, apply and receive approval before installation so financing is confirmed. SFK advises on the correct application sequence as part of your project planning.

Can I get rebates if I’m a landlord, not an owner-occupant?

CGHR is available to landlords on properties where they’re the registered owner. OAIR eligibility varies by delivery agent — confirm with your local program administrator. HELP (Toronto) is available to property owners including landlords of 1–6 unit residential buildings. Rental properties with tenants in place during installation require proper notification and a minimum 48-hour re-entry window after foam application.

How much can I realistically save on a spray foam project through rebates?

For a typical GTA attic spray foam project ($5,000–$10,000), combined rebates from OAIR + CGHR total $2,500–$4,500 — reducing net cost by 25–45%. Whole-home projects ($12,000–$20,000) with HELP + CGHR + OAIR can see total rebates of $6,250–$10,600, reducing effective out-of-pocket costs by 35–55%. Toronto homeowners using HELP at 0% interest pay nothing upfront, making energy savings cash-flow positive from day one.

What documentation does SFK provide for rebate applications?

SFK provides: itemized contractor invoice, installation photos with date stamps, post-installation R-value report confirming effective thermal performance, OBC SB-12 compliance documentation, and proof of installer certifications (SPFA, WSIB, $5M liability). This package satisfies documentation requirements for CGHR, OAIR, HELP, and CMHC applications.

Is spray foam eligible for the IESO Save on Energy program?

IESO’s Save on Energy programs cover insulation upgrades as part of combined energy retrofit packages — primarily for low-to-moderate income homeowners through the Affordability Fund. Spray foam qualifies as an insulation measure. Eligibility depends on your utility provider (Toronto Hydro, Hydro One) and household income. SFK provides contractor documentation needed for IESO applications.

What’s the best rebate program for a Scarborough or North York homeowner doing an attic upgrade?

Start with OAIR — the $1,250 attic rebate requires no EnerGuide audit and processes in 2–4 weeks. Book an EnerGuide pre-audit simultaneously to unlock CGHR, which adds $1,250–$2,500 for the attic stream. Combined: $2,500–$3,750 back on a project that typically costs $4,500–$8,000 in those neighbourhoods. If your mortgage is CMHC-insured, the same audit can trigger an additional 25% CMHC insurance refund.

What R-value does my spray foam attic need to qualify for OAIR?

OAIR requires the finished attic assembly to reach a minimum R-31 effective — achieved with approximately 5–6 inches of closed-cell spray foam (R-6/inch) or 8–9 inches of open-cell (R-3.7/inch). Most GTA attics upgraded from old fiberglass batts (R-12 to R-20) to spray foam easily meet or exceed this threshold. SFK measures and documents post-installation R-value to confirm OAIR eligibility before submitting your application.
