This CRA rebate disappears in October 2026 — Canadians could be missing out on over $1,000

Many Canadians assume the Canada Carbon Rebate is finished for good. Ottawa scrapped the consumer carbon tax in 2025, and the last regular quarterly payment landed that April. But if you never filed a tax return for 2021 through 2024, that’s not quite the end of the story — the Canada Revenue Agency (CRA) says those returns can still trigger a retroactive rebate once they’re assessed. The catch: the federal government has proposed a hard stop on that window, and it’s worth understanding how solid that deadline really is before you decide to file.

Why the rebate stopped — but isn’t fully gone

The federal fuel charge, which the carbon rebate was designed to offset, ended April 1, 2025. The CRA issued the final quarterly Canada Carbon Rebate (CCR) payment on April 22, 2025, to Canadians who had filed their 2024 tax return electronically by April 2. There have been no new quarterly CCR payments since. But the CRA has been clear on one point: Canadians who were eligible but haven’t yet filed their 2021, 2022, 2023 or 2024 tax return can still receive those payments once the CRA assesses the return. Filing is what triggers the money — no separate application is needed.

Who could still be owed money

The CCR applied only in provinces where the federal fuel charge was in place. Residents of British Columbia and Quebec, for example, were never eligible, since those jurisdictions run their own carbon pricing systems. To qualify, you generally had to be 19 or older in the month before payment, though younger Canadians with a spouse, common-law partner or child living with them may also qualify. Anyone who fell behind on filing during those years — including newcomers, students or people who simply didn’t file — could be sitting on unclaimed money for any year they were eligible.

The October 2026 cutoff Ottawa has proposed

This is where the timeline gets more complicated than a lot of headlines suggest. Budget 2025, tabled in Parliament on November 4, 2025, proposes amending the Income Tax Act so that no CCR payments would be made for tax returns or adjustment requests filed after October 30, 2026. That change isn’t law yet — it’s contained in Bill C-31, the second Budget 2025 implementation bill, which passed second reading in the House of Commons on June 3, 2026 and is now before the Senate Standing Committee on National Finance. Until it receives royal assent, the cutoff remains a proposal rather than a confirmed rule. Still, a government proposal with a specific date attached is a strong signal of where policy could be headed, and filing sooner could potentially help remove some risk tied to how or when the bill is finalized.

How much this could be worth

The value varies by province, family size and how many years you missed. For the 2024-25 benefit year alone, a family of four could receive up to $1,800 in Alberta, $1,504 in Saskatchewan, $1,200 in Manitoba and $1,120 in Ontario, with smaller base amounts in the Atlantic provinces. Someone who hasn’t filed since 2021 could be eligible for payments across four separate benefit years, though earlier years generally paid less before the rebate’s rural top-up doubled in 2024. There’s no single number that applies to everyone, so the CRA’s My Account portal is the only reliable way to see what you’re personally owed.

What to do before the window narrows

Don’t wait to see whether Bill C-31 passes before you file. A return that’s already been filed locks in your eligibility regardless of how the legislation shakes out, while waiting only adds risk if the October 2026 date becomes law. Start with your oldest unfiled year, since it’s furthest from any deadline, and file electronically — that’s what gets an assessment, and a payment, moving fastest.

What to do now

• Log into CRA My Account to check which tax years from 2021 to 2024 are still unfiled or unassessed
• File any outstanding returns electronically, starting with the oldest year, since NETFILE assessments move fastest
• Don’t wait for Bill C-31 to pass — a return already filed and assessed locks in your eligibility even if the October 2026 cutoff becomes law
