22 Insulation Statistics: Costs, Wages and Ontario Rebates (2026)
Cited data on what attic insulation costs in Ontario, which Enbridge and Save on Energy rebates apply, what Ontario insulators earn, and how US attic prices compare.
Most Ontario attic insulation jobs cost $3,000 to $4,000 before HST, according to Goose Insulation's 2026 pricing guide, and eligible homeowners can claim up to $1,250 through Home Renovation Savings when they raise attic insulation to at least R-50. Insulation slows heat flow through attics, walls and basements so heating and cooling systems work less. The 22 statistics below cover Ontario prices, rebates, wages and US benchmarks.

How much does attic insulation cost in Ontario?
Ontario attic prices sit higher than many US national averages because crews target deeper R-values and often include air sealing and baffles. Local contractor guides and rebate rules are the best planning tools for GTA and Ontario homes.
1. Most Ontario attic jobs cost $3,000 to $4,000 before HST
Goose Insulation puts most attic insulation jobs at $3,000 to $4,000 before HST in 2026. That band covers an average-size attic topped up toward R-60 with air sealing and baffles included (Goose Insulation).
2. Smaller Ontario attics can start near $2,500
The same guide puts smaller, simpler jobs from about $2,500 before HST when existing insulation is dry and stays in place and hatch access is easy (Goose Insulation).
3. Large or complex Ontario jobs can reach $10,000
Big footprints, full removal, difficult access or extensive air sealing can push Ontario attic work up to $10,000 before HST. Pricing is confirmed on site, not by phone (Goose Insulation).
4. Square footage is the largest price driver
Goose lists attic square footage as the single largest cost driver, followed by starting depth, access, whether old material must come out, and how much air sealing the attic needs (Goose Insulation).
5. Removal is not always required
Blown-in insulation can go over clean, dry existing material in most cases. Removal is needed when insulation is moisture-damaged, vermin-contaminated, compressed beyond use, or may contain vermiculite (Goose Insulation).

HomeGuide puts average attic insulation at $1,000 to $2,700 installed, with a national average near $1,800 and a full range from $500 to $6,000 (HomeGuide).

What this means for homeowners
Ontario attic upgrades cluster around a few thousand dollars before HST, and standalone rebates can offset up to $1,250 when you hit R-50 or higher from a low starting point. Worker wages near $35 an hour help explain crew pricing, while US guides show why per-square-foot quotes still need a local site visit. Ask every contractor what R-value they will leave, whether air sealing and baffles are included, and whether they are on the participating contractor list for Home Renovation Savings.
