Both pathways, every figure, and a link to the page it came from. No gate, no email, no “contact us for details”.
Work out your own number
Every figure on this page is below. This is the one that catches people out: the rebate cannot be more than half the invoice after tax. Drag the slider to your own invoice and pick the depth in your attic.
Tier pays $1,250 and half the invoice is $1,700, so the tier is the binding number. You get the full $1,250.
Illustrative arithmetic on published programme figures. The real number is on your quote before you sign anything.
No form, no email
Open the attic hatch and put a tape measure into the insulation. The depth you find is what sets your rebate. Pick the closest match below and the panel tells you roughly what you qualify for.
Pick a depth and the number appears here. No email, no phone number, no callback.
Enbridge Gas and Save on Energy run the Home Renovation Savings programme together, with support from the Ontario government. It has two routes and they are not interchangeable.
One measure. No energy advisor. Must be installed by a participating contractor, and the programme website states that contractor registrations for the attic stream are currently closed. One attic rebate per home, ever.
| Existing insulation | Upgrade to | Maximum rebate |
|---|---|---|
| R–12 or less | R–50 | $1,250 |
| Over R–12 to R–25 | R–50 | $1,000 |
| Over R–25 to R–35 | R–50 | $800 |
| Cathedral / flat roof, R–25 or less | R–28 | $750 |
| Cathedral / flat roof, R–12 or less | R–20 | $650 |
An energy advisor assesses the house before the work and again after. At least two qualifying upgrades are needed; a third adds a $500 bonus. Slower, more paperwork, considerably more money if you are doing more than the attic.
| Upgrade | Maximum rebate |
|---|---|
| Attic, R–12 or less to R–50 | $1,500 |
| Attic, R–12 to R–25, to R–50 | $1,200 |
| Attic, R–25 to R–35, to R–50 | $900 |
| Exterior wall, more than R–20 added | $3,600 |
| Exterior wall, R–12 to R–20 | $2,100 |
| Exterior wall, R–7.5 to R–12 | $1,200 |
| Basement wall, more than R–22 | $1,500 |
| Basement wall, R–10 to R–22 | $900 |
| Crawlspace wall or ceiling | $600–$1,200 |
| Basement slab | $500 |

Amounts are set by Enbridge Gas and Save on Energy, quoted here from the programme pages — attic stream and assessment stream — checked 17 September 2026. Programme terms change without notice.
Most attic-rebate pages in Ontario carry a countdown to 30 November 2026. This one did too, until we went to check the source and could not find one. On 24 September 2026 we read both publishers — Save on Energy's programme page and the Home Renovation Savings site itself — and neither states an end date, a closing date or a deadline of any kind. The IESO's 2025–2027 conservation plan budgets the programme into 2027, inside a framework running to 2036.
That is not a promise it will run forever. It is funded year to year and the amounts have already been revised. It means only this: nobody selling you insulation knows when it ends, and the ones showing you a date are not quoting the programme. Ask them where the date is published.
What the programme does publish, and what is worth your attention, is the contractor list: “Contractor registrations for the attic program stream are currently closed; no new applications are being accepted.” That is checkable in one click, and it is the only hard limit on this rebate.
You do. The rebate is paid to the homeowner by the programme. We prepare and submit the file because we have to — the installing contractor is part of the claim — but the payment is yours and it does not come off our invoice unless we have agreed that in writing.
Programme processing times vary and are outside our control. We give you the submission and the reference so you can chase it directly rather than through us.
The Greener Homes grant is closed. The interest-free loan programme has its own rules and its own status, and you should check it directly rather than take a contractor's word for it.
Eligibility depends on programme dates and on when the work and the submission land. We book with that in mind and we tell you where you are in the queue. We do not take a deposit on a promise about a date we do not control.
