Two Paths for Insulation Rebates in Ontario
The Home Renovation Savings Program offers two distinct paths for insulation rebates. The path you choose determines how much you get back and whether you need an energy assessment.
Path 1: Standalone Attic Insulation (No Assessment)
The simplest option. A registered contractor upgrades your attic insulation, handles the paperwork, and you receive up to $1,250 back. No energy assessment needed. This was introduced in August 2025 and has become one of the program's most popular offerings — Great Northern Insulation alone completed hundreds of these upgrades. Cathedral ceiling or flat roof insulation qualifies for up to $750 through this path.
Path 2: Bundled Insulation (Assessment Required)
The higher-value option. Combine insulation with at least one other upgrade (air sealing, windows, doors, or heat pump water heater). A registered energy advisor assesses your home before and after the work. Combined insulation rebate: up to $7,700 covering attic, walls, basement, and crawlspace. Gas-heated homes can receive up to $5,000 total through the bundled path. Electrically heated homes qualify for up to $10,000.
