There is no Ontario gas tax rebate to apply for. Instead, the province has cut its gasoline and fuel tax rates at the source, so Ontario drivers already pay about 5.7 cents less per litre on gasoline and 5.3 cents less per litre on clear diesel every time they fill up. The lower rates were first introduced on July 1, 2022, and the 2025 provincial budget proposes making them permanent.1Government of Ontario. 2025 Ontario Budget, Chapter 1B, Keeping Costs Down
How Much You Save Per Litre
Ontario’s gasoline tax on unleaded fuel is 9.0 cents per litre, down from the pre-2022 rate of 14.7 cents. Clear diesel is taxed at the same 9.0 cents per litre, reduced from 14.3 cents.2Ontario.ca. Gasoline Tax Those cuts have been extended four times since 2022, most recently through June 30, 2025.1Government of Ontario. 2025 Ontario Budget, Chapter 1B, Keeping Costs Down
The province estimates cumulative relief of $1.7 billion since the cuts began, or roughly $380 per household over three years.1Government of Ontario. 2025 Ontario Budget, Chapter 1B, Keeping Costs Down
Nothing to File or Claim
The savings arrive at the pump. Fuel tax is collected from wholesalers and retailers before gasoline reaches the retail price, so the reduced rate is already built into what you pay. There is no form, no rebate cheque, and no residency test. Anyone buying fuel in Ontario pays the lower rate, whether they live in the province or are passing through.
Fuel wholesalers, importers, exporters, and interjurisdictional transporters still have to register with the Ministry of Finance for tax collection purposes, but that is a business obligation, not a way to claim savings.3Government of Ontario.

Proposal to Make the Lower Rates Permanent
In its 2025 budget, the Ontario government announced it will introduce legislation to amend the Gasoline Tax Act and the Fuel Tax Act to lock the 9.0-cent-per-litre rate in place for both gasoline and diesel.1Government of Ontario. 2025 Ontario Budget, Chapter 1B, Keeping Costs Down If that legislation passes, the rate no longer depends on repeated extensions and the old 14.7-cent and 14.3-cent rates will not return.
The Federal Canada Carbon Rebate Has Ended
If you’re searching for a rebate because you used to receive quarterly Canada Carbon Rebate payments, that program has been terminated. On March 15, 2025, the federal government set all fuel charge rates under the Greenhouse Gas Pollution Pricing Act to zero, effective April 1, 2025.4Government of Canada.

The Canada Revenue Agency has confirmed that the April 2025 payment was the final one, and no further quarterly CCR payments will be issued.5Canada Revenue Agency. Closed, Canada Carbon Rebate for Individuals The federal charge, which had reached 17.61 cents per litre on gasoline by April 2025, dropped to zero at the same time.4Government of Canada.

What This Means at the Pump
Two fuel costs have eased at once. The provincial tax remains 5.7 cents per litre below its historical rate on gasoline and 5.3 cents below on diesel, and the province is moving to make that permanent. The federal consumer carbon charge, which added more than 17 cents per litre by early 2025, has been eliminated. Neither change requires anything from you: the reduced provincial rate is applied automatically, and the federal charge simply no longer appears in the price.
