Ontario winters are long, and heating can take a big share of your yearly energy bill. If your attic insulation is old or too thin, warm air escapes through the attic and roof area. That usually leads to:
- Higher heating costs
- Drafty rooms and uneven temperatures
- More wear on your furnace or heat pump
The good news is that Ontario has rebate programs that can help reduce the cost of upgrading your insulation. This guide explains the current rebate options in plain English, plus the steps to apply.
Mas Air Home Comfort can also help you plan the right upgrade and keep the paperwork simple.

What rebate program covers insulation in Ontario?
Most insulation rebates you will see right now fall under the Home Renovation Savings Program. It is tied to Enbridge Gas and Save on Energy programs and is designed to improve home energy efficiency.
In most cases, you will see two paths:
- Single Upgrade
Faster and simpler. You can often complete the work first and then apply for the rebate. - Bundle Upgrades
Higher total rebates. You typically need a home energy assessment and at least two eligible upgrades.
If you live in Toronto, Mississauga, Markham, or anywhere in the GTA, these options are often available depending on your utility setup and home type.
Note: Rebate rules and amounts can change. Always confirm the latest details on the official program page before you start.
Option 1: Attic insulation rebate (Single Upgrade)
This option focuses on attic insulation. It is popular because it has fewer steps and can be completed quickly.
How much can you get back?
Rebate amounts usually depend on your current attic insulation level and the R value you upgrade to. Here is the common structure:
| Current attic insulation | Minimum target after upgrade | Max rebate |
|---|---|---|
| R-12 or lower | R-50 | $1,250 |
| R-12 to R-25 | R-50 | $1,000 |
| R-25 to R-35 | R-50 | $800 |
Some homes may qualify for rebates for cathedral ceilings or flat roofs with different targets and caps.
❓ What is R value?
R value tells you how well insulation resists heat flow.
- Higher R value means better insulation
- Many Ontario attic upgrades aim for R-50 to R-60
- Older homes often have R-20 to R-30, which can be worth upgrading
A stronger R value can help your home stay warmer in winter and reduce summer heat buildup in the attic.
Who usually qualifies?
Eligibility depends on program rules, but many homeowners need to meet basics like these:
- You must be the homeowner
- The home must be in Ontario
- Some new builds may not qualify
- Some home types, such as stacked townhomes, may be excluded
If you are unsure, the safest move is to confirm eligibility before you book the work.
Option 2: Higher rebates with Bundle Upgrades
If you plan to upgrade more than one item, Bundle Upgrades can unlock higher total rebates. Common combinations include:
- Attic insulation plus air sealing
- Attic insulation plus exterior wall insulation
- Insulation plus a heat pump upgrade
Typical requirements
- Start with a home energy assessment
- Complete at least two eligible upgrades
Common upgrades and maximum rebates
| Upgrade | Max rebate |
|---|---|
| Attic insulation | $1,500 |
| Exterior wall insulation | $3,600 |
| Foundation insulation | $2,300 |
| Windows and doors | $100 per opening |
| Air sealing | $250 |
| Heat pump water heater | $500 |
Some programs also provide support toward assessment costs, often up to $600.
Simple application checklist
Most homeowners follow a flow like this:
- Pick the right rebate path, Single Upgrade or Bundle Upgrades
- Confirm eligibility and required documents
- Book the work with a qualified contractor
- Complete the installation
- Submit proof and receive the rebate after approval
If you want to avoid mistakes, get help early. Many rebate issues come from missing paperwork, wrong product specs, or skipping a required step.
