The attic pays more here than on the no-assessment path
If you're already booking an assessment for other upgrades, do attic insulation through this tier instead, up to $1,500 (vs. $1,250) and $780 for cathedral ceiling (vs. $750).
Most Vaughan homes heat with natural gas furnaces, which puts insulation and air sealing in a stronger position than a heat pump switch alone, better envelope work lowers the gas bill directly rather than waiting on a mechanical upgrade. If you're in one of Vaughan's newer condo or high-rise buildings near the Vaughan Metropolitan Centre, insulation work on shared walls or the building envelope goes through your condo board, not you individually; the city's Climate Ready Homes Program free consultation is a reasonable starting point for a board comparing options.
How to claim it
- For attic: confirm eligibility, pick a participating contractor, get it installed, contractor submits the application
- For walls/foundation: book an energy assessment first, then follow the assessment-path steps
- Condo owners: get board approval documented before any exterior-wall work begins

Common questions
What insulation rebates are available in Vaughan?
Ontario's Home Renovation Savings Program covers attic, wall, and basement insulation, plus air sealing, usually as part of a broader retrofit. Amounts depend on the scope of work and typically run a few thousand dollars.
Do I need an energy audit first in Vaughan?
Yes. Ontario requires a pre-retrofit home energy assessment before insulation work qualifies, so the auditor can confirm the upgrade and measure the improvement afterward.
Does insulation help more than a heat pump switch in Vaughan?
For most Vaughan homes, which heat with gas furnaces, insulation and air sealing cut the gas bill directly and immediately, while a heat pump swap sits in the HRSP's lower tier since it's replacing an already-efficient gas system rather than electric resistance heat. Many homeowners do both, but insulation is the faster payback on its own.
Alectra Utilities bills you, but not for this one
Most of what Alectra Utilities does for a Vaughan homeowner is about electricity, metering it, delivering it, billing it. Insulation sidesteps that almost entirely, since the work is sealing your building envelope, not adding a new electrical load or appliance. Your rebate amount is fixed by the provincial program regardless of which utility happens to serve your street, so switching this project through the paperwork looks the same whether Alectra bills you or a different LDC does. The one place it's genuinely relevant: if your existing heat is electric baseboard, watch your Alectra bill for the drop once the insulation's done, that's the real-world proof the upgrade worked.
Vaughan's January nights get colder than you'd guess this close to Toronto
Ten winters of recorded data (2015-2024) put Vaughan's average January low at -8.6°C, dipping to -27.5°C on its coldest night, enough of a swing that an under-insulated attic or wall is doing real, measurable damage to a heating bill over a typical January. That gap between indoor comfort and outdoor cold is what the rebate tiers on this page are ultimately subsidizing: close it with proper insulation and the furnace simply runs less, months at a time, regardless of what the thermostat is set to.
