What Home Renovation Savings pays for insulation in Timmins
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.
Cold, old and in need of repair
The 2021 Census counts 7,125 owner-occupied detached houses built before 1981 in Timmins, and 72% of households live in homes of that age. 65% live in detached houses, 78% in an eligible type and 67% own. The record low from 2015 to 2024 was -39.3°C.
Hydro One and fuel
Timmins is served by Hydro One, which does not run these rebates. Heating fuel sets the overall cap: $10,000 for electricity, oil, propane or wood and $5,000 for Enbridge gas.
Planning around repairs
If the roof needs replacing, ask the roofer and the insulation contractor to coordinate, but do not let insulation work start before the in-home visit or first assessment. Work done earlier is not eligible and cannot be claimed later.
Remote scheduling
Assessment-stream audits need a registered energy advisor from an authorized service organization. In a northern centre, ask about travel fees and booking times early, because the December 31, 2026 post-audit date does not move.
Free help
The Energy Affordability Program from Save on Energy offers free upgrades to income-qualified households. Check it before paying for an assessment.
How to claim in Timmins
