Quebec City's long, cold winters make efficient windows a smart investment — and the province offers real help paying for them. If you own an older home in Vieux-Québec, Limoilou, or the suburbs, here's what may be available in 2026. Program rules and budgets change often — confirm current eligibility before you buy.
Quebec: Rénoclimat
Rénoclimat provides grants for eligible efficiency upgrades after a certified energy evaluation done before and after your project. Windows and doors that meet the program's performance criteria can qualify. Note that in heritage sectors of Vieux-Québec, product choices may also need to satisfy municipal and heritage requirements — coordinate both.
Hydro-Québec: LogisVert
Hydro-Québec's LogisVert program offers efficiency incentives; window eligibility depends on the current rules, so check it alongside Rénoclimat.
Federal: Canada Greener Homes Loan
The interest-free Canada Greener Homes Loan (up to $40,000 from NRCan) can help finance ENERGY STAR windows and doors. The former federal grant is closed to new applicants.
How to qualify
- Book a certified energy evaluation BEFORE work begins (required for Rénoclimat)
- In heritage areas, confirm approved materials and styles with the Ville de Québec first
- Choose high-performance windows meeting program criteria
- Keep all invoices and complete the follow-up evaluation
