Quick answer: Aurora’s homes range from heritage houses in the old village core near Yonge and Wellington to large two-storeys in the Hills of St. Andrew and newer homes in Bayview Wellington and Aurora Grove. Many of these attics sit well below R-50, and larger homes have big attic areas to fill. Pro Home Insulation upgrades Aurora attics to at least R-50, and the Home Renovation Savings Program currently offers up to $1,000 back when starting above R-12 to R-25. Amounts can change.

What Aurora homeowners should know about their attics
The historic centre of Aurora, often called Aurora Village, has older homes with steep roofs, additions and finished upper floors. Their attics can be small, broken up or partly sloped.
Neighbourhoods such as Aurora Heights, Aurora Highlands and the Hills of St. Andrew were built later, with larger, simpler attics. The east side, including Bayview Northeast and Bayview Wellington, is newer again. Larger homes mean more square footage to insulate, so the after-tax cost can reach the rebate cap faster.
6 signs your Aurora home is losing heat through the attic
- Big temperature gaps between floors. The second floor of a large two-storey is often the hardest to keep comfortable.
- Thin insulation over a bonus room or garage. Rooms above garages and additions are common weak spots.
- Ice dams on complex rooflines. Valleys and dormers trap snow, and attic heat melts it unevenly.
- Vaulted or cathedral ceilings. These have little space for insulation and may need a different approach.
- Squirrels in mature-tree neighbourhoods. Older streets with tall trees give wildlife easy access to roofs.
- Drafts around pot lights. Many renovated homes have unsealed pot lights that leak air into the attic.
How to look at a large attic without risk
Larger attics often have long runs where insulation depth changes. From the hatch, check depth near you and as far as your flashlight reaches. Do not crawl across the joists. Our guide to checking attic R-value shows what to look for.
Attic rebate tiers for Aurora homes
Aurora is served by Enbridge Gas, and homes heated with electricity, oil, propane or wood on the IESO grid also qualify. The rebate is 50% of the after-tax insulation cost, up to the tier maximum.
| Attic before upgrade | Upgrade to at least | Maximum rebate |
|---|---|---|
| R-12 or less | R-50 | $1,250 |
| Above R-12 to R-25 | R-50 | $1,000 |
| Above R-25 to R-35 | R-50 | $800 |
| Cathedral/flat roof, R-25 or less | R-28 | $750 |
| Cathedral/flat roof, R-12 or less | R-20 | $650 |
Details are on our Ontario attic insulation rebate page and the rebates hub.
Useful facts for Aurora homeowners
- New Ontario homes target about R-60 in attic ceilings (Ontario Building Code, SB-12).
- Air leakage represents about 20–30% of heat lost from an older home (Natural Resources Canada).
- Walls can account for about 20% of a home’s heat loss (Natural Resources Canada).
- Windows, doors and skylights can account for up to 35% of heat loss (Natural Resources Canada).
Open attic vs cathedral ceiling options
| Area | Typical method | Rebate target |
|---|---|---|
| Open attic | Blown fiberglass or cellulose | At least R-50 |
| Cathedral or flat section, R-25 or less | Spray foam or dense-pack insulation | At least R-28 |
| Cathedral or flat section, R-12 or less | Spray foam or dense-pack | At least R-20 |
| Room over garage | Dense-pack or spray foam in the ceiling | Depends on layout |
How we upgrade an Aurora attic
- Assess every area. We check the main attic, additions, bonus rooms and any sloped sections.
- Quote by area. The quote shows starting and target R-value and the expected rebate tier.
- Air seal. We seal pot lights, fans, chimneys and the hatch. See our air sealing service.
- Insulate. We add baffles and blow in attic insulation to at least R-50.
- Rebate paperwork. As a participating contractor, we help with the submission.
Aurora homeowner checklist
- List every attic area, including above the garage
- Note any vaulted or cathedral ceilings
- Check for unsealed pot lights on the top floor
- Confirm your heating fuel and that you own the home
- Ask whether a past owner claimed an attic rebate
Example project (illustrative)
example — not a specific customer.
A large 1980s two-storey in the Hills of St. Andrew has about R-22 in a wide, open attic.
- Upgrade: R-22 to R-50
- After-tax insulation cost: $3,000
- 50% of cost: $1,500
- Tier maximum (above R-12 to R-25): $1,000, so the rebate is $1,000
- Net cost after rebate: $3,000 − $1,000 = $2,000
- Heat flow through the insulation layer (simplified): 1 − 22/50 = about 56% less

Questions to ask before you sign
| Question | Why it matters |
|---|---|
| Did you measure every attic area? | Missed areas lead to cold rooms |
| Is air sealing in the price? | Insulation does not stop air leaks |
| What final R-value will I have? | The rebate needs at least R-50 for open attics |
| Are you a participating contractor? | Required for the rebate |
Frequently asked questions
My Aurora home has a cathedral ceiling. Can it get a rebate?
It may. Cathedral and flat roofs have their own tiers, with targets of R-28 or R-20 depending on the starting level. These spaces often need spray foam or dense-pack insulation.
Do heritage homes in Aurora need special care?
Older homes often have small, broken-up attics and older wiring. We check wiring and ventilation first and choose a method that fits the space.
Why does a big house hit the rebate cap?
The rebate is 50% of the after-tax cost, up to a tier maximum. A large attic costs more to insulate, so half of the cost can go over the cap.
Do I need an energy assessment?
Not for the standalone attic path. An energy assessment is only needed for the bundle path with two or more upgrades.
How long is the program running?
It is currently scheduled to run until March 31, 2027, but it can change or end early. Funding is first-come, first-served.
