Insulation and air sealing cut the heat a home needs in the first place, which lowers bills and lets you buy a smaller, cheaper heat pump or furnace later.
Use this guide to define the work, then ask about provider support through a contact enquiry.
For single-family homes, older homes with little insulation, renovations and new builds.
Commercial buildings must meet the energy code their province or city has adopted, which is often based on the National Energy Code of Canada for Buildings (NECB). Ask the contractor which edition applies to your project.
Spray foam insulates and air seals in one step, which makes it a good fit for rim joists, cathedral ceilings and hard-to-reach cavities.
It costs more per R-value than blown-in or batt insulation, so it's usually used where space is tight or air sealing matters most.
Start with the scope that suits your property, then compare written proposals using the same assumptions. These are project options, not a catalogue of available models or a promise of eligibility.
| Option | When to consider it | What to request |
|---|---|---|
| Attic and air sealing | Compare heat-loss paths, moisture and ventilation before adding material. | Specify coverage, target insulation level and air-sealing details. |
| Walls | Compare accessible cavities with exterior or interior retrofit scope. | Ask about material, moisture control, removal and finishing. |
| Basement and rim joists | Compare foundation moisture and air-leakage conditions. | Specify vapour/fire protection and treatment of penetrations. |
Areas and quantities, material, target insulation level, air sealing, moisture protection and finishing. Ask each provider to itemize equipment or materials, labour, extras, permits, exclusions, warranty and responsibility for rebate documents. Confirm eligible equipment, pre-approval and stacking with the program administrator before signing.
Budget separately: project cost → confirmed grant support → remaining cost. Any borrowing is repayable, with its own interest, fees and approval. Unconfirmed rebates are not awarded savings.
NRCan estimates that basements and walls each account for about 20% of a home's heat loss, windows and doors up to 25%, and air leakage typically about 25%. Basements and uninsulated walls usually lose more heat than the typical attic, even though the attic is where most people start.
| Where heat escapes | Share of heat loss |
|---|---|
| Air leakage (drafts) | About 25% |
| Windows and doors | Up to 25% |
| Basement | About 20% |
| Walls | About 20% |
NRCan recommends about R-40 to R-60 in the attic or roof, R-22 to R-40 in walls and R-19 to R-25 on basement walls. The higher values apply to colder regions with more heating degree-days. Local building codes set the legal minimums, so your contractor should confirm them.
| Part of the home | Zone A (up to 3,500 HDD) | Zone B (3,500–5,000) | Zone C (5,001–6,500) | Zone D (over 6,500) |
|---|---|---|---|---|
| Attic / roof | R-40 (RSI 7.1) | R-50 (RSI 8.8) | R-60 (RSI 10.6) | R-60 (RSI 10.6) |
| Walls | R-22 (RSI 3.9) | R-24 (RSI 4.2) | R-27 (RSI 4.8) | R-40 (RSI 7.1) |
| Basement walls | R-19 (RSI 3.3) | R-19 (RSI 3.3) | R-24 (RSI 4.2) | R-25 (RSI 4.4) |
| Floors over unheated space | R-27 (RSI 4.8) | R-31 (RSI 5.5) | R-40 (RSI 7.1) | R-50 (RSI 8.8) |
Closed-cell spray foam gives about R-6 per inch and air seals as it goes. Blown-in cellulose gives about R-3.6 per inch and glass fibre batts about R-3.2. Foam costs the most per R-value, so it's usually used where space is tight. Blown-in and batts are cheaper ways to add a lot of R-value to open attics.
| Material | R-value per inch | Air sealing | Typical use |
|---|---|---|---|
| Closed-cell spray foam | About R-6 (R-5.5 to 6.5) | Yes | Rim joists, basement walls, cathedral ceilings |
| Open-cell spray foam | About R-3.6 | Partly | Interior wall and roof cavities |
| Blown-in cellulose | About R-3.6 | No | Open attics, closed wall cavities |
| Blown-in glass fibre | About R-2.9 | No | Open attics |
| Glass fibre batt | About R-3.2 | No | Open stud walls, attic floors |
| Mineral fibre batt | About R-3.4 | No | Walls, basements, sound control |
Insulation is priced by the area covered and the R-value added, so the biggest cost drivers are how much of the home you insulate, the material and the thickness it needs. Rebates can cover a large share: Newfoundland and Labrador pays 75% of attic and basement insulation costs, up to $3,000.
What rebates cover: Ontario pays $1,000 to $1,250 for attic insulation on its own, or up to $7,700 for insulation after an energy assessment. BC pays up to $5,500 and Nova Scotia up to $5,000. See the rebate tables.
Yes. NRCan says air leaks through attic penetrations such as chimneys, vents, plumbing stacks and electrical boxes cause significant heat loss and moisture problems. Sealing them before adding insulation stops warm, moist air from reaching the cold attic, where it can condense and damage the roof and insulation.
Read NRCan's guidance on roofs and attics.
The federal Greener Homes Grant and Loan are closed, so 2026 insulation rebates come from provinces and utilities. Ontario pays $1,000 to $1,250 for an attic alone, or up to $7,700 after an energy assessment. BC pays up to $5,500, Nova Scotia up to $5,000, Newfoundland and Labrador up to $3,000, and Quebec $1,500 for roof insulation.
Federal: check program status and household or business eligibility
Province and utility: confirm service territory, equipment and pre-approval
Municipality: confirm property boundary and whether support is a grant or repayable loan
These are separate potential funding layers. Combination is subject to program rules; no combined saving is guaranteed.
The Greener Homes Grant is closed to new applicants, the Greener Homes Loan closed on Oct 1, 2025, and the Oil to Heat Pump Affordability program stopped taking applications on July 31, 2026. Separate support includes the no-cost Canada Greener Homes Affordability Program for income-qualified households, and the provincial programs below. National Heat Pump Rebate is upcoming. Applications open through an online portal in early 2027. Eligible installations from November 1, 2026 can be claimed once it opens, under the rules in force on the installation date. No payments are made before launch and approval. This household heat-pump announcement does not establish funding for other standalone upgrades. Read the official program rules.

An EnerGuide home evaluation by a Registered Energy Advisor measures where your home actually leaks heat, so you insulate the right places first. In Ontario it also unlocks the bigger rebates: $600 back on the assessment and up to $7,700 for insulation when you do two or more upgrades.
See Ontario's Home Renovation Savings program for both paths. After insulating, a smaller heat pump is often enough to heat the home.
Choose an insulation contractor who air seals first, states the R-value they'll install in each area, and knows the documentation your rebate program needs. Compare at least three written quotes that list the material, the thickness or R-value, and the area covered, so you can compare like for like.

Compare confirmed support separately from project cost and repayable loans.
Compare project optionsIt depends on the attic's size, the R-value you're adding and whether old insulation has to come out first. Rebates can cover a large share: Ontario pays $1,000 to $1,250 for attic insulation on its own, and Newfoundland and Labrador covers 75% of the cost for electrically heated homes, up to $1,000 for materials and $500 for labour.
Not always. NRCan data shows basements and uninsulated walls often lose more heat than the typical attic, about 20% each. Air leakage accounts for about 25%. An energy assessment shows where your home loses the most heat.
Ontario's Home Renovation Savings program pays $1,000 to $1,250 for attic insulation as a single upgrade. With a home energy assessment and two or more upgrades, you can get up to $7,700 for insulation, plus $600 back on the assessment.
Yes. NRCan says attic air leaks around chimneys, vents, plumbing and electrical boxes cause significant heat loss and moisture problems. Seal them first so warm, moist air can't reach the cold attic.
It depends where it goes. Closed-cell spray foam gives about R-6 per inch and air seals, so it's worth it on rim joists, basement walls and tight cavities where space is limited. It costs more per R-value, so for an open attic, blown-in cellulose (about R-3.6 per inch) gives more insulation for the money.
BC Hydro pays up to $5,500 for insulation. Nova Scotia pays up to $5,000 for upgrades recommended by a home energy assessment. Newfoundland and Labrador covers 75% of attic and basement insulation for electrically heated homes, up to $3,000, and Quebec's LogisVert pays $1,500 for roof insulation. Income-qualified households in several provinces can get free insulation through the Canada Greener Homes Affordability Program.
NRCan recommends at least R-40 in the mildest regions and R-50 to R-60 in most of the country. Check the local building code, which sets the minimum where you live.
