What to know
- Never assume an older federal, provincial or utility program is still accepting applications.
- Confirm the exact product model and performance requirement, not just the brand.
- Some programs require approval or an energy assessment before purchase or installation.
- Keep labels, paid invoices, model information and installation records.
Treat every incentive as time-sensitive
Window and door incentives may come from federal initiatives, provinces, municipalities, utilities or financing programs. Eligibility, funding and deadlines can change. A contractor’s old brochure or a search result is not confirmation that a program is open today.
The Canada Greener Homes Grant is an important example: Natural Resources Canada now describes it as closed and states that December 31, 2025 was the last day to submit documents. Do not plan a 2026 project around that former grant.
Check timing before ordering
Some programs require registration, approval or a pre-retrofit assessment before work begins. Others may restrict eligible homes, applicants, contractors, products, performance levels or installation dates. Read the current program page and save a copy of the rules that apply when you apply.
If a sales representative says a product qualifies, ask for the program name, exact eligible model and written requirement. Then confirm them yourself with the program administrator.
Verify the exact product
ENERGY STAR certification applies to specific products and configurations, not every item sold under a manufacturer name. Natural Resources Canada recommends checking model information against its searchable certified-products list.
Keep the ENERGY STAR labels and model information after installation. They can help establish what was supplied if an incentive application, warranty claim or future buyer requires documentation.
Build a clean project file
Keep one digital folder for the entire project. At minimum, include:
- Program rules, application number and approval notices
- Pre-work assessment or photos when required
- Signed contract and any approved change orders
- Manufacturer, series, model and performance documentation
- Product labels, paid invoice and proof of payment
- Installation date, installer details and warranty documents
Calculate the project without the rebate first
An incentive should improve an already sensible project, not make an unaffordable quote appear safe. Compare the full installed price, financing cost, warranty and scope before subtracting a rebate. Until the administrator confirms approval, treat the incentive as potential—not guaranteed—money.
