Gas prices in Calgary and the Alberta tax relief

A tax holiday the monthly average cannot see

Statistics Canada publishes Calgary's average pump price once a month, weeks after the month ends. Its latest figure, for September 2026, still includes the Alberta fuel tax of 13 cents a litre. That tax stopped on October 1, 2026 under the province's Fuel Tax Relief Program, so any reading of the September 2026 number as "today's price" would overstate it. The estimate column corrects for that.

For regular, the correction for the tax is −13.6¢ at the pump, GST included. The Edmonton rack price, published every business day by the Government of Ontario, then adds +2.3¢ for the wholesale movement since September 2026. The calculator below lists those parts with their dates.

The Fuel Tax Relief Program

Alberta ties its fuel tax to the price of oil. While the relief program applies, the 13-cent rate is not collected, and the province has said that will last until at least December 31, 2026. From January 1, 2027 at the earliest, the rate will be set at 0, 4.5, 9 or 13 cents depending on the price of WTI crude, and it cannot climb by more than 9 cents from one quarter to the next.

That leaves a Calgary litre with the 5% GST as its only tax for the moment: 7.4¢/L at the estimated price. No transit levy applies in Alberta and there is no provincial sales tax. This page will show the new Alberta rate as soon as it is published, and the forecast page follows both dated changes coming in 2027.

Two taxes that could come back in 2027

The federal excise tax of 10 cents a litre on gasoline has been suspended since April 20, 2026. Finance Canada's draft legislation (proposed, not enacted) brings it back at half rate on February 1, 2027 and in full on April 1, 2027. In Alberta, that return could coincide with a quarterly reset of the provincial tax, so a Calgary driver may see two increases in the first half of 2027. The calculator below measures the federal part alone for your monthly consumption.

If Alberta restores its full 13 cents at some point, the combined effect with the full excise would be 24.15¢/L per litre with GST, all else equal. Whether and when that happens depends on the oil price and the province's quarterly decisions.

Calgary over the last thirteen months

The Statistics Canada series is published under the Open Government Licence and appears in full below. Over the period, the highest monthly average was 176.9¢/L in May 2026 and the lowest 114.9¢/L in December 2025.
