What You Need to Know About Energy Audits for the Canada Greener Homes Program
What energy audits are required for the Canada Greener Homes program is a straightforward question with a clear answer: two EnerGuide evaluations are mandatory — one before your retrofits and one after.
Here is a quick breakdown:
- Pre-retrofit EnerGuide evaluation — completed before any home improvement work begins; assesses your home’s current energy performance and produces a Renovation Upgrade Report
- Post-retrofit EnerGuide evaluation — completed after eligible upgrades are finished; verifies the improvements and confirms your final EnerGuide rating
Both evaluations must be conducted by a certified energy advisor registered with Natural Resources Canada (NRCan). Without both, you cannot qualify for grant or loan funding under the program.
The Canada Greener Homes Grant officially closed for new document submissions on December 31, 2025, but understanding these audit requirements still matters — both for homeowners with applications still being processed and for those exploring related programs that carry similar evaluation standards.
The program received over 500,000 applications, making it one of the most widely used federal home efficiency initiatives in Canadian history. For Hamilton-area homeowners navigating these requirements, knowing exactly what each evaluation involves — and how to prepare — can save time and help you get the most from any available funding.

What Energy Audits Are Required for the Canada Greener Homes Program?
To qualify for the incentives provided by the federal government, you cannot simply perform upgrades and submit receipts. The program is built entirely around the EnerGuide Rating System, which is Canada’s official scoring system for home energy performance.
This means that to receive any financial support, you must book two distinct evaluations. These audits establish a scientific baseline of how your home uses energy, highlight where heat is escaping, and verify that your completed upgrades have actually made a measurable difference.
For homeowners in Hamilton, Burlington, Oakville, and surrounding areas, these audits are the key to unlocking the Canada Greener Homes Grant and its sister program, the interest-free Canada Greener Homes Loan.
Understanding the Pre-Retrofit EnerGuide Evaluation
The pre-retrofit EnerGuide evaluation is your home’s starting point. Think of it as a comprehensive health checkup for your house. During this assessment, a certified energy advisor will inspect your home from top to bottom.
A primary component of this audit is the blower door test. The advisor installs a temporary fabric door with a powerful, calibrated fan in one of your exterior doorways. This fan pulls air out of the house, lowering the indoor air pressure. As a result, outdoor air is forced inside through every unsealed crack, gap, and seam in your home’s envelope. Using specialized tools, the advisor measures the rate of air leakage and pinpoints exactly where drafts are occurring.
Additionally, the advisor will assess:
- Insulation levels in your attic, exterior walls, basement, and crawl spaces.
- Window and door quality, checking for thermal efficiency and air drafts.
- Mechanical systems, including your furnace, heat pump, air conditioner, and water heater.
Once the evaluation is complete, the data is uploaded to NRCan’s modeling software. You will receive two crucial documents:
- The Homeowner Information Sheet: A detailed summary of your home’s current energy performance.
- The Renovation Upgrade Report (RUR): A customized roadmap listing recommended upgrades that will yield the greatest energy savings for your specific property.
To remain eligible for funding, any retrofits you choose to undertake must be selected from the recommendations in your RUR.
Understanding the Post-Retrofit EnerGuide Evaluation
Once your chosen upgrades are complete—such as replacing an old furnace with an energy-efficient heat pump or improving your attic insulation—you must schedule your post-retrofit EnerGuide evaluation.
This second audit serves as the verification phase. The energy advisor returns to your home to perform another blower door test and inspect the newly installed systems or materials. They will check that the products used are eligible under program guidelines (for example, ensuring that any heat pumps or windows are certified models purchased through Canadian distributors).
After verifying the work, the advisor calculates your home’s new, improved energy rating. You will receive an updated EnerGuide label showing your home’s reduced energy consumption. This final evaluation is the trigger for your final grant disbursement or the release of your interest-free loan funds. Without this second step, the program cannot verify the success of the retrofits, resulting in the forfeiture of your funding.
How to Prepare for Your Home Energy Audit
A home energy audit is a highly detailed process that can take up to four hours to complete. Preparing your home beforehand ensures the energy advisor can work efficiently and capture accurate measurements.
Steps to Take Before the Energy Advisor Arrives
To help the evaluation go as smoothly as possible, we recommend taking the following steps before your scheduled appointment:
- Clear Access Paths: The advisor must physically inspect your attic, crawl spaces, basement, and all windows and doors. Ensure that furniture, storage boxes, or personal items are moved aside to provide clear, safe access to these areas.
- Prepare the Attic Hatch: Since attic insulation is a major factor in heat loss, the advisor will need to look inside your attic. If your attic hatch is located in a closet, empty the closet beforehand.
- Gather Utility and Property Documents: Have your recent heating and electricity bills ready, along with your property tax bill (to prove homeownership) and a government-issued ID (to confirm the property is your primary residence).
- Prepare Combustion Appliances: If you have a wood-burning fireplace or stove, ensure it is completely cool and clean of ashes. The blower door test creates negative pressure, which can pull ash into your living spaces if the fireplace is not prepared.
What Happens During and After the Evaluation
When the certified advisor arrives, they will walk through your home, taking measurements and photographing key components like your heating systems, water heater, and insulation.
During the blower door test, all exterior doors and windows must remain closed, and interior doors should be left open. The advisor will also perform a combustion spillage test on any fuel-burning appliances to ensure there are no safety hazards related to exhaust gases.
Within a few weeks of the evaluation, your registered service organization will upload the data and send you your Renovation Upgrade Report.

Eligibility, Special Considerations, and Program Differences
The energy audit process is central to both the federal grant and loan programs, but how the audits are utilized and financed can differ depending on which stream you are using.
| Program Feature | Canada Greener Homes Grant | Canada Greener Homes Loan |
|---|---|---|
| Status | Closed to new applicants (processing existing) | Open for active applications |
| Pre-Retrofit Audit Required? | Yes | Yes |
| Post-Retrofit Audit Required? | Yes | Yes |
| Audit Cost Support | Reimbursement contribution available | Can be financed within the loan |
| Upfront Funding | Paid after all work and final audit are complete | Up to 15% upfront for contractor deposits |
What Energy Audits Are Required for the Canada Greener Homes Program Grant vs. Loan?
While the grant program is no longer accepting new registrations, the Canada Greener Homes Loan remains a highly popular option, offering interest-free financing over a 10-year term.
The audit requirements for the loan are identical to those of the grant: you must complete both a pre-retrofit and a post-retrofit EnerGuide evaluation. However, the loan program offers a unique advantage: you can include the upfront cost of both energy audits in your total loan amount, allowing you to finance the assessments interest-free over a decade.
Furthermore, once your pre-retrofit audit is complete and your loan is approved, you can access up to 15% of the approved loan amount upfront. This initial disbursement helps cover contractor deposits for major upgrades like heat pumps, with the remaining balance released after the post-retrofit audit verifies the completed work.

What Energy Audits Are Required for the Canada Greener Homes Program for Already Completed Retrofits?
A common question we hear from homeowners in places like Stoney Creek, Grimsby, and Burlington is: “Can I get a rebate for a heat pump I already installed before my energy audit?”
Unfortunately, the answer is no. Under the strict program guidelines, any retrofits completed before your pre-retrofit EnerGuide evaluation are ineligible for funding. The program relies on the initial audit to establish a “before” snapshot of your home’s efficiency. If the work is already done, the advisor cannot measure the baseline performance, and the upgrades will not qualify.
The only historical exception applies to retrofits and audits completed after December 1, 2020, provided that both the pre- and post-retrofit evaluations were properly documented and submitted within the program’s active timelines. If you are planning new upgrades, always ensure your energy advisor has completed the pre-retrofit assessment before your contractor starts any installation work. You can learn more about these timeline rules in our guide on Canada Greener Homes Grant Eligibility for Heat Pump Installation Ontario 101.
Frequently Asked Questions About Greener Homes Audits
Who is eligible to perform the EnerGuide evaluations?
Only certified energy advisors registered with Natural Resources Canada (NRCan) are authorized to perform these evaluations. These advisors work for licensed service organizations. When registering for the program, you must select a service organization active in your region (such as the Hamilton-Niagara corridor) to schedule your audits.
What happens if I do not complete the post-retrofit evaluation?
If you fail to complete the post-retrofit evaluation, you will not receive any grant money, and any approved loan funds will not be fully released. The post-retrofit audit is the legal verification that the upgrades were installed and that your home’s energy performance improved. Skipping this step results in complete program disqualification.
Are there any programs that do not require an energy audit?
Yes! The federal Oil to Heat Pump Affordability program, designed to help homeowners transition from oil heating to high-efficiency heat pumps, does not require a home energy evaluation in most cases. If you currently heat your home with oil, you may be eligible for direct funding without the need for pre- and post-retrofit audits.
