Sudbury sits in a considerably colder zone than the GTA, which changes the payback but not the rebate. The Home Renovation Savings attic stream is province-wide, and the tiers below are the same in Sudbury as they are in Toronto.
We work in Sudbury. Our coverage runs across Ontario, from Toronto to the northwest. Dates outside the Greater Toronto Area are booked by appointment and confirmed with you before anything is scheduled, so ask early rather than late. Where we work.
Greater Sudbury's housing is heavily post-war, much of it built during the mining expansion with shallow attics by today's standard. With heating degree days roughly forty per cent above Toronto's, the same attic upgrade saves materially more here in a year than it does in the GTA — which means the payback period is shorter, not longer, even though the rebate is identical.
No energy assessment, one measure, and the tier set by the depth already in the attic.
| What is up there now | Upgraded to | Maximum rebate |
|---|---|---|
| R–12 or less — under about 4 inches | R–50 | $1,250 |
| R–12 to R–25 — about 4 to 8 inches | R–50 | $1,000 |
| R–25 to R–35 — about 8 to 11 inches | R–50 | $800 |
Amounts are set by Enbridge Gas and Save on Energy and are quoted from the programme pages — attic stream, assessment stream — checked September 2026.
The rebate is capped at 50% of the invoice after tax, there is one attic rebate per home ever, and the work must be done by a contractor already registered on the programme's attic stream. The programme website states that registrations for that stream are currently closed.
Ask any contractor quoting you two questions before anything else: whether they are a participating contractor on the Home Renovation Savings attic stream, and what depth they measured at the joist. Then confirm the first with the programme directly rather than taking anyone's word for it, ours included. The programme's own page is here.
You will see 30 November 2026 on a lot of insulation websites. We read both programme publishers on 24 September 2026 and neither states an end date. Ask anyone showing you that date where it is published. What the programme does state is that its attic contractor list is closed to new applicants, and that is the limit worth caring about.
Tell us the depth you can see at the hatch and roughly when the house was built and we can give you the tier and the figure before anyone drives anywhere. If the job is straightforward and you already have an inspection or assessment report, we may not need a visit before the work at all. How a job actually runs.
