Quick answer: To claim Ontario’s attic insulation rebate, confirm you own the home and your attic is R-35 or less, hire a participating contractor, have the attic upgraded to at least R-50, sign the program form, and let the contractor submit photos, depth readings and your invoice. The rebate is 50% of the after-tax cost, up to $1,250, and typically arrives within a few months of approval.

Key takeaways
- The standalone attic path needs no energy assessment.
- The contractor must be a participating contractor and usually submits the application.
- Your rebate tier depends on your attic’s R-value before the work, so it must be documented first.
Step 1: Check you are eligible
You qualify if:
- You own the home in Ontario.
- It is heated by Enbridge natural gas, or electricity, oil, propane or wood on the provincial grid.
- Your attic is R-35 or less (R-25 or less for cathedral ceilings and flat roofs).
- Your home has not received an attic rebate from Enbridge, Save on Energy or Home Renovation Savings before.
Step 2: Estimate your current R-value
From the hatch, measure the insulation depth with a ruler and multiply by about 3 (fiberglass) or 3.5 (cellulose). Do not touch loose, pebbly, grey-brown or gold insulation — it may be vermiculite. Full instructions: how to check your attic R-value.
Step 3: Book an assessment with a participating contractor
The contractor measures your attic properly, takes “before” photos and depth readings, and confirms your tier:
| Before | Target | Max rebate |
|---|---|---|
| R-12 or less | R-50 | $1,250 |
| Above R-12 to R-25 | R-50 | $1,000 |
| Above R-25 to R-35 | R-50 | $800 |
| Cathedral/flat, R-25 or less | R-28 | $750 |
| Cathedral/flat, R-12 or less | R-20 | $650 |
Step 4: Get a written quote with the rebate shown
Your quote should list the target R-value, depth, material, air sealing, baffles, after-tax price and the estimated rebate (50% of the after-tax cost, up to your tier’s cap). Use our quote comparison template if you are comparing contractors.
Step 5: Sign the program form
The contractor gives you the homeowner form for the attic rebate. Read it, check your name, address and heating type, and sign. Keep a copy.
Step 6: Prepare for install day
- Clear a path to the attic hatch.
- Move items stored near the hatch.
- Make sure any wildlife issue has been fixed.
- Plan to be home at the start and end of the job.
Step 7: The work is done
A good install includes air sealing major leaks, baffles at the eaves, insulation to the target depth, insulated and weatherstripped hatch, and depth markers you can see from the hatch.
Step 8: The contractor submits the application
They send the “before” and “after” photos and readings, your signed form and the invoice. Ask for a copy of what was submitted.
Step 9: Receive your rebate
Rebate cheques typically arrive within a few months of the application being approved. If you have not heard anything after a few months, ask your contractor to check the status.
Mistakes that cost homeowners their rebate
| Mistake | What happens | How to avoid it |
|---|---|---|
| Using a contractor who is not participating | Application can be refused | Ask before you sign |
| No “before” photos or readings | Tier cannot be confirmed | Make sure they are taken |
| Stopping short of R-50 | Does not meet the requirement | Ask for R-60 for a buffer |
| Already got an attic rebate before | Not eligible again | Check your records |
| Waiting too long | Program may change or close | Book early |

example
example — not a specific customer.
A Pickering homeowner with about 5 inches of cellulose (around R-18) books an assessment in November. The quote is $2,100 after tax to reach R-60. The rebate is the lesser of 50% of $2,100 ($1,050) and the $1,000 cap, so $1,000. Net cost: $1,100.
Frequently asked questions
Can I apply for the attic rebate myself?
For the standalone attic path, the participating contractor usually submits the application with your signed form. You can track it and keep copies of everything.
What documents are needed?
Typically before and after photos, insulation depth readings, your signed homeowner form and the contractor’s invoice. Requirements can change, so your contractor should confirm the current list.
How long does it take to get the rebate?
Typically within a few months of approval. Busy periods can take longer.
What if my attic is just above R-35?
A standard attic above R-35 does not qualify for the attic path. You may still benefit from air sealing or other upgrades through the bundle path.
Can I get the rebate on a cottage?
Seasonal homes can qualify for the attic path if they meet the program requirements, including heating type and ownership.
