2026 Window & Door Rebates in Ontario can be a helpful way to reduce the net cost of upgrades, but rebates are usually rules-driven—and many homeowners miss out simply because they do things in the wrong order. In Barrie, the most common problem isn’t choosing the “wrong” window; it’s ordering and installing before confirming eligibility steps like energy evaluations, product requirements, and documentation.
This guide is intentionally written without dollar figures or guarantees. Program names and rules can change, and eligibility depends on your home, your chosen products, and your compliance with current terms. What we can do is show you the checks that most often decide whether an application is accepted—and how to avoid the easy mistakes before you commit to an order.
If you’re still early in planning, start with our Barrie windows and doors service page and keep this post open as your “before ordering” checklist.
The biggest mistake: ordering first and “hoping it counts”
A rebate application typically lives or dies on a few fundamentals:
- Whether the product you buy is actually considered an eligible window/door (often tied to ENERGY STAR certification and eligible product lists).
- Whether you follow the typical sequence, where a pre-retrofit evaluation is completed before installation and a post-retrofit evaluation confirms what was installed.
- Whether you keep the right proof (labels, model info, and invoices) long enough for verification.
Homeowners often assume: “If it’s energy efficient, it must qualify.” The reality is closer to: “If it’s the right model and it’s documented and the steps are followed, it may qualify.”
What “eligible product” usually means (in plain language)
Many rebate-style programs in Canada and Ontario use a similar logic: the window or door needs to be ENERGY STAR certified and appear on an eligible product list for the program. That means two important things for your quote and order:
- You need more than “ENERGY STAR quality” as a description.
You want the brand, model number, and any reference information clearly stated on your quote so you can verify eligibility against the program’s list. - You need to keep the temporary ENERGY STAR label until the process is complete.
NRCan’s guidance for windows and doors explicitly says: do not remove the ENERGY STAR labels until after your post-retrofit evaluation, because those labels help confirm what was installed.
If you only remember one line from this article, make it this: keep your labels and paperwork until the final evaluation is done.
Scope pitfalls: what to clarify before you sign anything
Even if you choose a high-performance window, the scope of what’s being replaced can matter.
Full-unit replacement vs “partial” replacement
Programs that recognize windows and doors as energy retrofits typically focus on replacing the full unit (window/door unit as installed), not just swapping glass or doing small partial changes. NRCan’s eligible retrofits language is oriented around replacing windows and doors as part of building-envelope upgrades, not “glass-only” improvements.
That doesn’t mean partial repairs are bad—they can be smart maintenance. It means you should not assume a “glass-only” change will be treated like a qualifying retrofit under rebate rules.
The quote should match the final installed scope
A rebate process often relies on documents that match reality: model info, invoices, and what was installed. If the quote is vague or the invoice doesn’t clearly describe the product and scope, verification can become difficult later. Enbridge-style terms also emphasize submitting invoices for audits and qualified measures as part of completion.
If you’re comparing contractors, clarity in scope isn’t just “nice to have”—it’s part of protecting your rebate paperwork.
The typical sequence to expect (and why order matters)
Most rebate pathways follow a simple structure. The names vary, but the steps are usually recognizable:
- Pre-retrofit evaluation / energy assessment
This establishes a baseline and identifies recommended upgrades. In some programs, both pre- and post-retrofit evaluations are part of eligibility. - Energy evaluations (including blower door testing) are typically completed by a registered energy advisor—not the window and door installer. Our role is to help you choose and install the right windows/doors and keep the quote and invoice details clear for your documentation.
- Confirm eligibility requirements before ordering
This includes confirming that the model you plan to buy is eligible (often via program lists) and that your planned scope meets program requirements. - Installation
This is when you’ll want clean documentation: invoice(s), product details, and photos if needed. Keep labels on the units until the post-evaluation. - Post-retrofit evaluation
This confirms the upgrades. Some terms explicitly define “Pre-Audit” and “Post-Audit” (or equivalent evaluations) as part of the process. - Submission of documentation
Terms commonly stress that you must satisfy requirements and submit the right documents; submitting an application does not automatically guarantee a rebate.
If you’re not sure which evaluation applies to you, your energy advisor or the current program terms are the best source. The key takeaway is to avoid doing the installation “first” without verifying the process for your specific program.
Barrie homeowner checklist (copy/paste before ordering)
Use this checklist as a quick self-audit.
If you’re unsure which evaluation you need, we can tell you what to ask your energy advisor before you order—reach us through our contact page.
- I have checked current Ontario/Canada rebate program requirements (not last year’s blog posts).
- I have confirmed whether a pre-retrofit evaluation is required before installation.
- I have a plan for the post-retrofit evaluation after installation.
- My quote includes the brand and model number for each window/door, so eligibility can be verified against program lists.
- The windows/doors I’m considering are ENERGY STAR certified and can be checked against an eligible list when applicable.
- I will not remove ENERGY STAR labels until after the post-retrofit evaluation is complete.
- I understand whether my project is full-unit replacement (not glass-only), and I’m not assuming partial work qualifies.
- I’m keeping all invoices and proof of purchase/installation, since terms may require submitting invoices for audits and measures.
- I have photos of installed units and labels if documentation is needed later.
- I’ve clarified what installation includes (retrofit vs full-frame, finishing, sealing), so the scope is consistent from quote to invoice.
- I have a timeline that leaves room for evaluations—so I’m not forced into rushing steps.
- If anything is unclear, I will verify requirements directly with the program/energy advisor rather than guessing.
If you’d like, we can help you translate this checklist into a clean scope and a quote that includes the details you’ll want for documentation. The easiest way to start is to request a measurement through our window installation planning page or discuss options for door installation.
If you’re about to order and you want a quick second set of eyes on scope, product details, and timing, reach out through our contact page and tell us what you’re planning.

FAQ: 2026 rebates and “what to check”
Do I need an energy evaluation before I replace windows or doors?
Many rebate processes require both a pre-retrofit and post-retrofit home energy evaluation (or equivalent audits) as part of eligibility, so it’s important to confirm this before ordering.
Are windows and doors both typically considered in rebate-style programs?
Some official eligible retrofit guidance covers windows and doors as categories, but you still need to verify current program rules and eligible product lists for your specific application.
Why does the product model number matter so much?
Eligibility is often tied to lists of specific models, so the model number (and any reference information) helps confirm the exact unit is eligible rather than a generic “ENERGY STAR” claim.
Why should I keep the ENERGY STAR labels?
NRCan’s guidance for eligible windows and doors says not to remove the labels until after the post-retrofit evaluation because they help confirm the installed product is ENERGY STAR certified.
Do glass-only replacements usually qualify the same way as full replacements?
Rebate logic for eligible retrofits is typically oriented around replacing windows and doors as retrofit measures; don’t assume glass-only work will be treated the same—confirm it before you proceed.
What documents should I keep?
Keep invoices and proof of purchase/installation, since program terms may require submitting invoices for audits and qualified measures as part of completion.
Can program rules change during the year?
Yes—requirements, eligible product lists, and processes can change, which is why it’s best to verify current terms before ordering.
What’s the safest way to avoid missing a step?
Follow the sequence (pre-evaluation → confirm eligibility → install → post-evaluation → submit documents) and keep labels and invoices until the process is complete.
2026 Window & Door Rebates in Ontario can be worth exploring, but the best outcome comes from treating rebates like a process, not a surprise discount.
