Ontario homeowners can claim up to $1,250 in attic insulation rebates through the Home Renovation Savings (HRS) standalone program — with no energy assessment required, and rebate cheques arriving in as little as 2–4 weeks. If you are upgrading multiple areas of your home at once, HRS multi-measure rebates stack to $10,000 total. A new federal program — the Canada Greener Homes Affordability Program (CGHAP) — is also launching in 2026, adding a second rebate layer for qualifying lower-income households.
This guide cuts through the program complexity. Below you will find a side-by-side decision matrix for every active Ontario attic rebate program, a cost-after-rebate grid for five common attic sizes, a step-by-step application checklist, and clear eligibility rules — everything you need to know before booking your attic insulation upgrade. Spray Foam Kings is an approved HRS contractor serving Toronto, Scarborough, North York, Etobicoke, Vaughan, Mississauga, Markham, and Brampton, and we handle all rebate paperwork on your behalf.
Ontario Attic Insulation Rebates at a Glance: Up to $1,250 (HRS) or $10,000 (Multi-Measure)
The maximum attic insulation rebate available to most Ontario homeowners in 2026 is $1,250 through the Home Renovation Savings (HRS) standalone program. This is the fastest, simplest path: no pre-installation energy assessment, paperwork submitted after the job is done, and payment by rebate cheque or natural gas bill credit within 2–4 weeks. If you plan to insulate your attic, basement walls, and add other energy upgrades in the same project, the HRS multi-measure stream allows you to stack rebates across measures up to $10,000 total — though this path requires energy assessments before and after the work.
The Canada Greener Homes Grant (CGHR), which previously offered up to $5,000 for attic insulation, closed to new applicants on December 31, 2025. Homeowners with a pre-retrofit assessment completed before the closure deadline may still submit final claims if all conditions are met. A successor federal program — the Canada Greener Homes Affordability Program (CGHAP) — is in active development with $800M in federal funding allocated, but eligibility criteria and rebate amounts for Ontario homeowners have not been confirmed as of August 2026.
For full details on all Ontario insulation rebate programs beyond attic-specific coverage, see our Ontario Insulation Rebate Hub.
HRS Standalone Attic Rebate: $650–$1,250 Based on Your Starting R-Value
The HRS standalone attic rebate pays between $650 and $1,250 depending on how little insulation your attic currently has — the lower your starting R-value, the larger your rebate. This is the fastest, most accessible program for attic-only projects: no energy assessor is required, the contractor handles the documentation, and most homeowners receive payment within 30–45 days of submitting the application.
Attic insulation rebate tiers under HRS standalone:
| Attic Type | Starting R-Value | HRS Rebate Amount | Target R-Value |
|---|---|---|---|
| Standard (flat ceiling) attic | Below R-20 | $1,250 | R-60 |
| Standard attic | R-20 to R-26 | $1,000 | R-60 |
| Standard attic | R-27 to R-35 | $800 | R-60 |
| Standard attic | R-35 or above | $650 | R-60 |
| Cathedral ceiling | Below R-35 | $750 | R-35 |
| Cathedral ceiling | R-35 or above | $500 | R-35 |
Key detail: The rebate is calculated as 50% of eligible material costs (after tax), capped at the tier amount. If your material costs are below $2,500, your actual rebate may be less than the tier maximum. For most spray foam attic projects, material costs comfortably exceed the threshold for the full rebate.
Eligibility checklist for HRS standalone attic:
- Primary residence (owner-occupied) in Ontario
- Heated by natural gas (Enbridge), electricity, oil, or propane
- Existing attic insulation below target R-value
- Installation by a licensed, insured professional contractor
- Invoice includes R-value added, area (sqft), total cost with HST
- Application submitted via Enbridge Save on Energy portal (gas) or saveONenergy.ca (electricity)
- No previous rebate claimed for the same attic upgrade
Use our Spray Foam Cost Calculator to estimate your attic project cost and confirm the rebate tier that applies to your home.
HRS Multi-Measure: Stack Attic + Other Upgrades for Up to $10,000
The HRS multi-measure stream delivers significantly larger total rebates — up to $10,000 — by combining your attic insulation upgrade with other eligible measures such as basement insulation, exterior wall insulation, window and door replacements, or heating system upgrades. The trade-off is time: this path requires a pre-installation energy assessment by a licensed energy advisor (typically $300–$600, partially rebated) and a post-installation assessment to verify results, adding 4–8 weeks to the timeline.
When HRS multi-measure is worth the extra steps:
- You are planning attic and basement insulation in the same project — combined rebates of $3,000–$5,500 are common
- You are replacing heating equipment alongside insulation work
- Your attic and basement both start below R-20, qualifying you for maximum rebate tiers on both measures
- Total upgrade cost exceeds $15,000 — the assessment cost becomes negligible relative to the rebate return
For ROI modelling on combined attic and basement projects, see our Energy Payback & ROI Calculator.
Canada Greener Homes Grant (CGHR): Closed — What Pending Applicants Need to Know
The Canada Greener Homes Grant (CGHR) stopped accepting new applications on December 31, 2025. If you did not complete a pre-retrofit EnerGuide assessment before the closure date, you are ineligible for this program. Homeowners who did complete a valid pre-retrofit assessment before December 31, 2025 may still be eligible to submit a final claim — but only if all eligible upgrades are complete and the post-retrofit assessment has been filed with NRCan before their individual application deadline.
If you have an open CGHR application in progress, contact Spray Foam Kings at 647-641-6881 to confirm your timeline and ensure your documentation meets NRCan’s requirements before your deadline passes.
Canada Greener Homes Affordability Program (CGHAP): New in 2026 for Lower-Income Households
The Canada Greener Homes Affordability Program (CGHAP) is a new $800M federal initiative announced in the 2024 federal budget, designed to replace CGHR with income-targeted support for low-to-median income households. As of August 2026, CGHAP eligibility criteria, rebate amounts, and Ontario delivery mechanisms have not been officially confirmed. The program is expected to prioritize households in Peel Region and Toronto CMA where affordability gaps are largest.
What is expected when CGHAP launches:
- Income threshold eligibility (likely $75,000–$90,000 household income cap for full rebate)
- Rebate amounts for attic insulation potentially $500–$2,000 (estimates; not confirmed)
- Expected to stack with provincial HRS rebates
- Will likely require application through a government portal, with contractor verification
We recommend booking your attic insulation upgrade under HRS now (deadline November 30, 2026) and layering in CGHAP if you qualify once it launches. Do not delay your project waiting for CGHAP — HRS expires first.
Attic Rebate Eligibility by Heating Type: Which Program Is Right for Your Home?
Your heating fuel type determines which Ontario attic rebate programs you can access — natural gas customers apply through Enbridge’s HRS portal, while electricity, oil, and propane customers apply through Save on Energy. Both pathways lead to the same rebate tiers.
| Heating Fuel | HRS Standalone Eligible? | HRS Multi-Measure Eligible? | CGHAP Eligible? | Application Portal |
|---|---|---|---|---|
| Natural gas (Enbridge) | ✅ Yes | ✅ Yes | ✅ Yes (if income-eligible) | Enbridge HRS portal |
| Electricity (Ontario utilities) | ✅ Yes | ✅ Yes | ✅ Yes (if income-eligible) | saveONenergy.ca |
| Heating oil | ✅ Yes | ✅ Yes | ✅ Yes (if income-eligible) | saveONenergy.ca |
| Propane | ✅ Yes | ✅ Yes | ✅ Yes (if income-eligible) | saveONenergy.ca |
| Wood/biomass only | ⚠️ Verify eligibility | ⚠️ Verify eligibility | Unknown (not confirmed) | Contact Save on Energy |
| Cornwall Electric customers | ❌ Ineligible | ❌ Ineligible | Unknown | N/A |
Eligibility flow for Ontario attic rebate:
- Is your home your primary residence? No → ineligible for all programs. Yes → continue.
- Do you heat with natural gas, electricity, oil, or propane? No → verify with Save on Energy. Yes → continue.
- Have you previously claimed a rebate for the same attic upgrade on this property? Yes → ineligible for that measure again. No → continue.
- Is your attic insulation below R-60? No → may not meet program requirements. Yes → eligible for HRS standalone.
- Are you upgrading other measures in the same project? Yes → consider HRS multi-measure for larger total rebate.
Cost-After-Rebate: 5 Attic Sizes × 2 Foam Types × 2 HRS Paths
The table below shows the installed cost, maximum HRS rebate (assuming starting R-value below R-20 for maximum $1,250 tier), and net cost after rebate for five common GTA attic sizes using open-cell and closed-cell spray foam. All costs are in CAD and include HST.
| Attic Size | Open-Cell Cost (est.) | Net After $1,250 HRS | Closed-Cell Cost (est.) | Net After $1,250 HRS | Net After $3,000 Multi-Measure† |
|---|---|---|---|---|---|
| 800 sqft | $2,000–$2,800 | $750–$1,550 | $2,800–$4,000 | $1,550–$2,750 | $0–$1,000 |
| 1,000 sqft | $2,500–$3,500 | $1,250–$2,250 | $3,500–$5,000 | $2,250–$3,750 | $500–$2,000 |
| 1,200 sqft | $3,000–$4,200 | $1,750–$2,950 | $4,200–$6,000 | $2,950–$4,750 | $1,200–$3,000 |
| 1,500 sqft | $3,750–$5,250 | $2,500–$4,000 | $5,250–$7,500 | $4,000–$6,250 | $2,250–$4,500 |
| 2,000 sqft | $5,000–$7,000 | $3,750–$5,750 | $7,000–$10,000 | $5,750–$8,750 | $4,000–$7,000 |
† Multi-measure net cost assumes $3,000 total HRS rebate across attic + one additional measure (e.g., basement insulation). Actual multi-measure rebate varies by project scope. Open-cell installed cost range: $2.50–$3.50/sqft. Closed-cell installed cost range: $3.50–$5.00/sqft. All prices GTA market; call 647-641-6881 for a site-specific quote.

| Application process | Online portal (Enbridge or saveONenergy.ca) | Energy advisor coordinates; homeowner submits portal | NRCan portal (closed) | TBD — expected federal/provincial portal |
| Stacking allowed? | Yes — stack with other HRS measures | Yes — stack across all measures up to $10,000 | Was stackable with provincial; now closed | Expected to stack with HRS |
| Expiration | November 30, 2026 | November 30, 2026 | Closed December 31, 2025 | Unknown — not yet launched |
Bottom line: For most GTA homeowners in 2026, HRS Path A is the right choice for attic-only projects. It is the fastest, simplest, and most accessible path. If you are doing a whole-home energy upgrade, pursue Path B for the larger stacked rebate.
Attic Rebate Application Timeline: From Quote to Rebate Cheque
The HRS Path A timeline is the shortest rebate process available for Ontario attic insulation — from quote to cheque in as little as 5–7 weeks total.
| Step | HRS Path A (Standalone) | HRS Path B (Multi-Measure) |
|---|---|---|
| Day 1 | In-home quote (free); confirm eligibility | Book licensed energy advisor for pre-assessment |
| Day 3–7 | Schedule installation | Pre-work energy assessment conducted ($300–$600) |
| Day 7–10 | Installation completed (1–2 days for attic) | Receive EnerGuide report; schedule installation |
| Day 10–14 | Contractor provides invoice + documentation package | Installation completed (1–3 days multi-measure) |
| Day 8–14 | Submit application via Enbridge or saveONenergy.ca | Book post-work energy assessment (within 30 days) |
| Day 18–22 | Application under review | Post-assessment completed; report submitted |
| Day 30–45 | Rebate cheque or bill credit arrives ✅ | Application submitted post-assessment |
| Day 60–90 | — | Rebate cheque or bill credit arrives ✅ |
Spray Foam Kings prepares your complete documentation package — invoice with R-value notation, WSIB clearance, and liability certificate — so your application is ready to submit the same week your installation is complete. Typical Path A rebate processing time from our clients: 28–35 days.
When You Don’t Qualify: Attic Rebate Disqualifications
You are disqualified from Ontario attic insulation rebates in six specific situations — knowing these in advance prevents wasted applications and project delays.
- Prior rebate claimed for the same attic upgrade: If you already received CGHR, HER+, or HRS rebates for attic insulation at this property, you cannot claim again for the identical measure. You may still claim for different measures (e.g., basement walls).
- Rental properties and multi-unit buildings: Only owner-occupied primary residences qualify. Landlords and condo corporations are generally ineligible under HRS standalone.
- Non-primary residences: Cottages, vacation properties, and investment properties do not qualify.
- Cornwall Electric customers: This municipally-owned utility is not part of the HRS program delivery network.
- DIY installation: Self-installed insulation using consumer kits is ineligible for all programs. Professional, contractor-installed work with proper documentation is required.
- Attic already at target R-value: If your existing insulation already meets or exceeds R-60, the program has no upgrade to rebate.
Why Spray Foam Achieves the Best Attic R-Value — and Delivers Better Rebate ROI
All three main insulation types — spray foam, fiberglass, and cellulose — qualify for the HRS attic rebate at the same dollar amounts. But spray foam delivers superior energy performance that maximizes the return on your post-rebate investment, primarily because of its air-sealing effect and long-term R-value stability.
| Attribute | Closed-Cell Spray Foam | Open-Cell Spray Foam | Blown-In Fiberglass | Blown-In Cellulose |
|---|---|---|---|---|
| R-value per inch | R-6.0–6.5 | R-3.5–3.7 | R-2.2–2.7 | R-3.2–3.8 |
| Installed cost (GTA, attic) | $3.50–$5.00/sqft | $2.50–$3.50/sqft | $0.80–$1.50/sqft | $0.60–$1.20/sqft |
| Rebate eligible (HRS) | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes |
| Air-sealing effect | Excellent (zero gaps) | Good (minimal gaps) | Poor (20–30% gap loss) | Fair (10–20% gap loss) |
| Settling risk (10-year) | None | None | 5–10% R-value loss | 10–20% R-value loss |
| Net energy savings (annual est.) | $300–$500/yr | $200–$350/yr | $100–$200/yr | $100–$180/yr |
Cellulose settling of 10–20% over 10 years can bring your attic back below target R-values, costing $200–$400 per year in additional heating costs — effectively eroding the value of your rebate over time. Spray foam maintains its R-value permanently. For comparison context, see our detailed Spray Foam vs Fiberglass Batt comparison and the Ontario Rebates Hub for stacking strategies.

FAQ: 13 Questions on Ontario Attic Insulation Rebates
Do I qualify for the attic insulation rebate in Ontario?
Yes — most Ontario homeowners qualify. You need a primary residence, heating with an eligible fuel (natural gas, electricity, oil, or propane), and existing attic insulation below R-60. Condos, rental properties, non-primary residences, and homeowners who already claimed an attic rebate for the same upgrade are ineligible. Call 647-641-6881 and we will confirm your eligibility in minutes.
What is the difference between HRS Path A and HRS Path B?
HRS Path A requires no energy assessment and delivers your rebate in 2–4 weeks — ideal for attic-only projects. Path B requires pre- and post-work energy assessments by a licensed advisor, takes 8–12 weeks, but allows you to stack rebates across multiple measures (attic, basement, walls) up to $10,000 total. Choose Path A for attic-only; Path B when upgrading multiple areas.
How much rebate will I get for my 1,200 sqft attic?
Up to $1,250 under HRS standalone if your attic currently sits below R-20. If your starting R-value is R-20–R-26, the rebate is $1,000; R-27–R-35 earns $800; R-35+ earns $650. A 1,200 sqft attic with open-cell foam costs approximately $3,000–$4,200 installed, meaning the maximum rebate cuts your net cost to $1,750–$2,950.
Can I get an attic rebate if my attic already has some insulation?
Yes — the program is specifically designed for top-up projects. As long as your existing level is below R-60 (standard attic) or R-35 (cathedral ceiling) and you have not previously claimed an attic rebate, you qualify. Your rebate amount is determined by your starting R-value, not your ending level.
What happens if I have already claimed an attic rebate in the past?
You cannot claim again for the same attic upgrade on the same property. However, if your prior claim was for a different measure (basement, walls), you remain eligible for an attic rebate as a new measure. Contact us to review your rebate history before booking.
Does spray foam qualify for larger attic rebates than fiberglass?
The maximum dollar amount is the same ($1,250 for HRS standalone). However, closed-cell spray foam achieves R-6 per inch — nearly double fiberglass’s R-3.2 — and creates a permanent air barrier that eliminates the 25–40% heat loss that occurs through fiberglass gaps. This means spray foam delivers significantly better annual energy savings ($300–$500/yr vs $100–$200/yr), accelerating your payback after the rebate is applied.
Can I stack the HRS attic rebate with other programs?
Yes — you can stack the attic rebate with other HRS measures (basement, walls, windows) up to $10,000 total through the multi-measure stream. The Canada Greener Homes Grant (CGHR) is closed. The new CGHAP program is expected to stack with HRS for income-eligible households when it launches, but stacking rules are not yet confirmed.
When does the Ontario attic insulation rebate expire?
The HRS program expires November 30, 2026. Applications must be submitted before this date. Extensions have not been announced. Book and complete your installation by late October 2026 at the latest to ensure paperwork is submitted well before the deadline.
How long does it take to receive the rebate after installation?
HRS Path A (standalone attic) takes 2–4 weeks from application submission. From the installation date, most Spray Foam Kings clients receive their cheque in 28–35 days total. HRS Path B (multi-measure) takes 8–12 weeks due to the required post-installation energy assessment before the application can be submitted.
What documentation do I need to apply?
You need: contractor invoice (insulation type, R-value added, sqft, total cost with HST), property tax bill, proof of primary residence, proof of heating fuel, and contractor’s WSIB clearance and liability certificate. Spray Foam Kings delivers the complete documentation package the same week as installation.
Can I DIY spray foam and claim the rebate?
No — DIY installation is ineligible for all Ontario rebate programs. The rebate requires professional, contractor-installed insulation with a proper invoice. Consumer DIY spray foam kits also typically fail to achieve consistent R-values and air-sealing performance required to pass program specifications.
Why is spray foam better than cellulose for attic rebate ROI?
Cellulose settles 10–20% over 10 years, dropping your attic’s effective R-value below target and costing $200–$400 per year in additional heating. This erodes the value of your rebate investment over time. Spray foam maintains its R-value permanently, making every dollar of rebate you collect compound in value year over year rather than declining with settling.
Will the rebate cover my entire attic upgrade cost?
Not entirely, but it makes a significant dent. For a 1,000 sqft attic with open-cell foam ($2,500 installed), the $1,250 rebate covers exactly 50% of the cost. For closed-cell foam on the same attic ($4,000 installed), the rebate covers about 31%. Stacking multi-measure rebates (attic + basement) can bring net project costs significantly lower — some clients reach under $1,000 net for open-cell attic upgrades.
