Quebec has some of the most generous home-efficiency programs in Canada, which is good news for Montreal homeowners replacing aging windows on the city's older triplexes and greystones. Here's what may be available in 2026. Program rules and budgets change often — confirm current eligibility before you buy.
Quebec: Rénoclimat
Rénoclimat is the province's flagship program. After a certified energy evaluation before and after your work, you can receive grants for eligible measures — including windows and doors that meet the program's performance criteria. The evaluation is the key first step.
Hydro-Québec: LogisVert
Hydro-Québec's LogisVert program offers incentives for a range of efficiency upgrades. Coverage focuses on heating, insulation, and envelope improvements, and eligibility for windows depends on the current program rules — worth checking 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 starting work (required for Rénoclimat)
- Choose ENERGY STAR / high-performance windows that meet program criteria
- Keep all invoices and use a qualified installer
- Complete the follow-up evaluation to receive your grant
