What Home Renovation Savings pays for insulation in Oshawa
We re-read the program's pages and both eligibility documents on October 3, 2026. There are two ways in: an attic-only stream with no assessment, and the assessment stream, where insulation, windows, air sealing and a heat pump water heater are bundled.
Attic, no assessment
The attic stream pays half of the after-tax cost, up to $1,250 for an attic from R-12 or less to R-50, $1,000 from R-25 or less and $800 from R-35 or less. A participating insulation contractor must do the work.
Attic, with assessment
In the assessment stream an attic brought to at least R-50 pays $1,500, $1,200 or $900 by starting R-value, pro-rated by the share of the roof you insulate (minimum 50%).
Cathedral ceiling or flat roof
$750 in the attic stream and $780 in the assessment stream. Any combination of attic, cathedral and flat roof counts as one measure, capped at $1,500 in the assessment stream.
Exterior walls
$1,200 for R-7.5 to R-12 added, $2,100 for more than R-12 to R-20 and $3,600 for more than R-20. Minimum 20% of wall area, pro-rated.
Basement walls, slab and headers
Walls up to $1,500, a slab $500 and a header $300. Wall plus slab is capped at $2,000, and all three at $2,300.
Crawl space and exposed floors
Crawl space walls $600 or $1,200, ceiling $1,200, header $300, combined up to $2,700. An exposed floor over a garage earns $300 at R-20 or more.
Semis and row homes
Semi-detached and end-unit row homes get 75% of the walls and basement maximums. Middle-unit rows get 50%.
Audit rebate and cap
The assessment stream returns $600 for the audits and caps insulation rebates at $7,700, inside an overall $10,000 limit, or $5,000 for Enbridge gas homes.

Attic stream work must be finished by November 30, 2026 and entered in the system by December 31. In the assessment stream, the post-audit must be scheduled by November 30 and completed by December 31, 2026, or within 180 days of your first assessment.
The housing picture
The 2021 Census counts 56% of Oshawa households in detached houses, 74% in an eligible type and 64% owning. 6.3% report needing major repairs, above the rate in Whitby. Oshawa has 5,360 semi-detached and 6,490 row households, which receive 75% or 50% of the wall and basement maximums.
Oshawa Power is not the program
Your electric utility is Oshawa Power (Oshawa PUC Networks). It does not run or change the insulation rebates, which come from Enbridge Gas and Save on Energy. Your heating fuel does matter for the overall cap, $10,000 for electricity, oil, propane or wood and $5,000 for Enbridge gas.
An attic from R-20
For an attic starting between R-12 and R-25, the attic stream pays 50% of the after-tax cost up to $1,000, and the assessment stream pays up to $1,200 pro-rated by area. Both need R-50 at the end. If the attic is large and the quote is high, the assessment stream may pay more, but it needs a second measure.
Don't pre-empt the visit
Work completed before the in-home visit, or before the first assessment, is not eligible. Keep the contractor from starting until the visit has taken place, and keep the invoice dates clear.
How to claim in Oshawa
- Confirm your house type and heating fuel.
- Choose a stream: pre-register for the attic stream, or book a home energy assessment for the full bundle.
- Get quotes that state the R-value you start with, the R-value you reach and the share of each surface you will insulate.
- Do not start any work until the in-home visit or first assessment has happened.
- Keep invoices and your property tax bill for the paperwork, and finish before the November 30 and December 31, 2026 dates.
