Pre-approval is the design, and the portal does not exist yet
Look at the sequence in the table above. Approval comes before purchase. You apply, you get a decision within 24 hours, you buy the approved heat pump, you upload receipts. That design is fast and audit-free. It also has a gap built into it for anyone acting now.
The portal is not live. As of October 21, the federal "One million home energy retrofits" page offers only an email sign-up for news about launch dates, eligibility, rebate amounts and how to apply.
Government officials told CTV News they are aiming for a launch in early 2027. The Canadian Press quoted Prime Minister Mark Carney saying the details have not been finalized.
So the question becomes retroactivity. Will a heat pump installed in November 2026 qualify for a program that opens in, say, February 2027? Nobody can say yes. Officials told CTV they are exploring options for retroactive eligibility, and CBC News reported that Ottawa is eyeing making the rebate retroactive to fall. Those are reports of intent, not rules. No federal page states that pre-launch installations will be covered, what start date would apply, or what documentation a retroactive claim would need.
This is the real stake in the budget date. It is tempting to read November 5 as the day money arrives. It is more useful to read it as the next official document in which Ottawa could put the launch date, the retroactivity window, or the funding profile on paper. Officials have also said they announced the program months early to consult with industry and let installers stock up. Budget Day lands in the middle of that consultation, which is exactly when terms are still movable.
