A plain-language reference for fleet, construction, and warehouse operators in Southwestern Ontario. The federal carbon charge on propane went to zero on April 1, 2025; the Ontario propane levy was repealed on July 1, 2025. The full 16.68 cents per litre came off the road-vehicle side of a commercial account — autogas at the cardlock, propane-fuelled commercial vehicles. Only the federal 12.38 cents per litre came off propane that heats a construction site or fuels a forklift inside a warehouse. The math, the regulations, and what is still on the invoice in 2026.
Two propane-tax changes hit Ontario invoices in 2025. The federal carbon charge on propane went to zero on April 1; the Ontario propane levy was repealed on July 1. The combined statutory removal is 16.68 cents per litre of tax that no longer appears on a Canadian propane invoice — the single largest one-time line-item change on Ontario propane in the past decade.
For a commercial operator, the practical effect depends on where the propane is going. Road-vehicle propane — autogas at a cardlock, propane-fuelled commercial vehicles, fleet auto-propane accounts — saw the full 16.68¢/L drop. Stationary commercial propane — temporary heat on a construction site, forklift cylinders inside a warehouse, propane heating in a shop or yard — saw the federal 12.38¢/L only, because the Ontario Gasoline Tax Act propane levy had never applied to stationary use.
This article is the plain-language reference for both halves of a commercial account: what changed, where the rules are written down, what the math looks like, and what is still on the invoice. The companion piece for farm operators — where almost all the propane is stationary and the dollar story is the 12.38¢/L side — lives here.

The federal change applied to every litre of propane regardless of how it was burned. The Ontario change applied only to propane used in licensed motor vehicles — auto-propane at a cardlock, propane-fuelled commercial vehicles, propane-fuelled interjurisdictional carriers. The distinction is the Gasoline Tax Act one, not a B&J one, and it is the reason the per-litre answer on a commercial account depends on which side of the account you are asking about.
The federal fuel charge under the Greenhouse Gas Pollution Pricing Act (GGPPA) was the propane line that did not care what the propane was for. Forklift cylinder, construction-site heater, bobtail-fed autogas dispenser, fleet auto-propane, residential furnace — the federal charge on propane was 12.38 cents per litre from April 1, 2024 to March 31, 2025, and SOR/2025-107 set that rate to zero effective April 1, 2025.
The Canada Gazette wording was specific:
"the Amending Regulations will cease the application of the fuel charge, starting on April 1, 2025, by setting the applicable charge rates in Schedule 2 of the Greenhouse Gas Pollution Pricing Act to zero."
The Act remains in force; the rate is what was zeroed. That is the regulatory structure, not a forecast — a future government could reset the rate by regulation without new legislation. The current zero rate is the current state of the rule, not an eternal property of it.
For a commercial operator, the federal change is the floor under the savings number: every commercial propane account in Ontario saw at minimum the 12.38¢/L come off the base, plus the HST that no longer recaptures on top of it. The road-vehicle side saw more. The stationary side saw only this.
The Ontario Gasoline Tax Act propane levy was 4.3 cents per litre. It applied to propane used as a motive fuel in a licensed motor vehicle under Ontario's Highway Traffic Act — auto-propane dispensed at a cardlock or fleet pump, propane-fuelled commercial vehicles, interjurisdictional carriers. Stationary propane — propane in a forklift cylinder used inside a warehouse, propane in a Sure-Flame or Frost Fighter on a construction site, propane in a shop heater, propane in a yard generator — was already non-taxable under the Gasoline Tax Act before July 1, 2025.
Bill 24, the Plan to Protect Ontario Act (Budget Measures), 2025, amended the Gasoline Tax Act to remove the road-vehicle propane levy effective July 1, 2025. Ontario.ca's current Gasoline Tax page now states the post-change rule plainly: "as of July 1, 2025, all uses of propane are non-taxable."
The dollar effect on a commercial account therefore splits at the same line the statute did:
The reason the change feels invisible on a construction or warehouse invoice is that there was no line to remove. The accounting on the stationary side had already been at zero for years; the July 2025 change simplified the bookkeeping (distributors no longer track dual-track propane), but the per-litre price on the heater pad on a job site did not move.
Two worked examples, both on a 4,000-litre delivery at an indicative pre-tax base of $0.80 per litre. One delivery into an autogas dispenser at a cardlock; one delivery into bulk site-heat storage on a construction job. Same supplier, same truck, same wholesale price — different per-litre tax answer.

| All-in delivered | $4,369.94 | $3,810.36 | $3,616.00 | −$753.94 |
A 4,000-litre fleet autogas delivery at the same wholesale price is about $754 lighter all-in in 2026 than it would have been in early 2024. The $667.20 is the statutory base reduction; the additional $86.74 is HST that no longer recaptures on top of the higher base.

| All-in delivered | $4,175.58 | $3,616.00 | $3,616.00 | −$559.58 |
A 4,000-litre site-heat delivery at the same wholesale price is about $560 lighter all-in in 2026 — the federal piece plus its HST recapture. The July 2025 column is identical to the April 2025 column because the Ontario change had no effect on this line.
The two cases meet at the same post-July-2025 invoice when the base price is identical: $3,616.00 all-in on a 4,000-litre drop at $0.80/L base. The difference is entirely about where they started two years earlier — the autogas line started higher and fell further.
After both 2025 changes, the propane line on a commercial invoice in Ontario carries exactly one tax: HST at 13%. The federal Excise Tax Act, R.S.C. 1985, c. E-15, Part IX is the statutory authority; the rate is the harmonized rate for Ontario.
For an HST-registered commercial operation — every incorporated construction, fleet, or warehouse business is — the 13% is recoverable as an input tax credit. It is a working-capital line, not a permanent cost.
What this means at the desk: a 2026 propane invoice should show the delivered base price (commodity + logistics + dealer margin) plus HST. Nothing else. No federal carbon charge. No Ontario propane levy. No clean-fuel-regulation surcharge on the propane side. If an invoice in 2026 carries a line that looks like a carbon charge or a provincial propane tax, that is worth a phone call to the supplier — it is a bookkeeping error, not a statutory line.
The wholesale propane price at the Sarnia hub has not moved because of the tax changes. The bulk-haul cost from Sarnia to a regional plant in Waterloo or London has not moved. The last-mile bobtail allocation, tank-rental amortization, TSSA and insurance line, dispatch and admin overhead — none of these moved. Dealer gross margin per litre has not moved because of the tax changes either.
What moves a commercial bill week to week is the commodity layer. The Sarnia rack price moves daily on global propane fundamentals — crude, US LPG export demand, winter degree-days across Ontario and Quebec, the status of pipeline routes into Sarnia. The tax change was a one-time step in 2025; the commodity has been moving every week before, during, and since. The verified Sarnia reference points published by the New Brunswick Energy & Utilities Board (OPIS-sourced, the cleanest public re-publication in Canadian-dollar units) put the rack at 33.40 CAD¢/L on December 13, 2025 and 36.81 CAD¢/L on May 8, 2026. That is the layer that produces the seasonal variation a commercial buyer feels at the desk.
For a construction operator on a winter pour, a warehouse running a high-utilization forklift fleet, or a regional fleet manager with an autogas account, the protection against a winter spike is contract structure — pre-buy, fixed-price, or volume-tiered arrangements — not the tax line. The tax line is the same on every supplier's invoice in Ontario. The commodity exposure is the part the contract structure manages.
The Greenhouse Gas Pollution Pricing Act remains in force; the charging rate is what SOR/2025-107 set to zero. A future government could reset the rate by regulation; new legislation is not required. The Department of Finance Canada published proposed amendments in May 2025 that would permanently repeal Part 1 of the GGPPA in phases — April 2025 charging provisions, October 2025 rebate provisions, November 2025 registration, April 2035 full wind-down. As of May 2026 those amendments have not been enacted. The current state is the current law, not a permanent property of the statute.
The Ontario change is statutory — the Gasoline Tax Act itself was amended by Bill 24. Reversing it would require new legislation, not just a regulatory amendment.
There is no replacement consumer carbon levy at the federal or Ontario level as of May 2026. Industrial Output-Based Pricing System pricing continues for large industrial emitters under SOR/2019-266; that regime does not reach a regional fleet operator, a small-to-mid-sized construction GC, or a single-site warehouse. If your business is large enough to be reporting into OBPS, you already know.
Autogas at a cardlock, propane-fuelled commercial vehicles, fleet propane accounts: the full 16.68¢/L came off the base, plus the HST that no longer recaptures on top of it. A 4,000-litre delivery is about $754 lighter all-in at the same wholesale price than it would have been in early 2024.
Construction-site temporary heat, forklift cylinders inside a warehouse, shop and yard propane heat: only the federal 12.38¢/L came off the base, plus its HST recapture. A 4,000-litre delivery is about $560 lighter all-in at the same wholesale price. The Ontario change did not move this line because the line was already at zero.
Both halves of the account in 2026: HST at 13% is the only tax on the invoice. Recoverable as an input tax credit for HST-registered operations.
The line that moves your bill week to week is the wholesale commodity price at Sarnia, not the tax line. The tax change was a one-time step.
