Oakville homeowners can receive a $1,250 rebate on attic insulation as a standalone upgrade through the Ontario Home Renovation Savings program, administered by Enbridge Gas and Save on Energy (IESO). No pre-upgrade energy assessment is required for a standalone attic insulation application. If you upgrade attic insulation along with other eligible measures in a single bundled application, the insulation rebate can reach up to $7,700, and a $600 rebate offsets the cost of the required home energy assessment. Oakville's housing stock includes a large number of homes built between the 1950s and 1990s in communities such as Old Oakville, Bronte, Glen Abbey, and Clearview that are frequently under-insulated by modern standards. Newer communities including Joshua Creek, River Oaks, and North Oakville subdivisions built after 2000 were constructed to better insulation standards, but may still benefit from an assessment. Both Enbridge Gas customers and Oakville Hydro (electric) customers are eligible for the Home Renovation Savings program. Several programs that were active in earlier years are now closed: the Canada Greener Homes Loan (closed 2025), the Enbridge HER+ program (closed December 31, 2025 and replaced by the Home Renovation Savings program), and the Canada Greener Homes Grant (closed February 2024).

The main program is the Ontario Home Renovation Savings program, which offers a $1,250 rebate for attic insulation as a standalone upgrade. No pre-upgrade energy assessment is required for standalone applications. If you bundle the insulation with other eligible upgrades in a single application, the rebate can reach up to $7,700 and a pre-upgrade home energy assessment is required (you receive a $600 rebate to cover its cost). Apply through homerenovationsavings.ca.
No, not for a standalone attic insulation application. The Home Renovation Savings program allows single-upgrade applications without an energy assessment. An assessment is required only if you choose the bundled path (two or more upgrades in one application), in which case you earn a $600 rebate to offset the assessment cost.
Costs for attic insulation in Oakville depend on attic square footage, current insulation level, accessibility, and the type of insulation material. A typical Oakville home ranges from roughly 1,000 to 1,500 square feet of attic space. Getting at least three quotes from licensed insulation contractors will give you an accurate range for your specific home. Contractor.ca can connect you with licensed Oakville insulation contractors.
Ontario Building Code recommendations and the Home Renovation Savings program typically align with a minimum R-60 for attic insulation in Ontario's climate zone. Many pre-1990 Oakville homes have R-20 to R-30 or less, making them strong candidates for the rebate. Your insulation contractor will assess the current R-value and recommend the appropriate upgrade.
Yes. The Home Renovation Savings program's bundled path lets you combine attic insulation, a heat pump, and other eligible measures in a single application. The bundled path requires a pre-upgrade home energy assessment, but you earn a $600 rebate to offset it. Total bundled insulation rebates can reach $7,700 and total heat pump rebates can reach $7,500 or more depending on equipment type.
