Oct. 1. Somebody on Macleod Trail pulls a work truck up to a pump, looks at the sign, and starts doing math.
Here’s the math.
Alberta’s fuel tax is $0.13 a litre on gasoline and diesel. From Oct. 1 it’s zero. GST gets charged on top of that tax, so taking it off pulls about $0.1365 a litre out of the bill. That last number is our arithmetic, not the province’s.
On a 50 litre fill, that’s $6.83. On 60 litres, $8.19. Also ours.
Real money. For a guy who fills a truck twice a week, it’s lunch.
Key facts
- Alberta Treasury Board and Finance states that the provincial fuel tax on gasoline and diesel, normally $0.13 per litre, is suspended effective October 1, 2026, through at least December 31, 2026.
- Under the Government of Alberta’s Fuel Tax Relief Program, the fuel tax falls to $0 per litre when West Texas Intermediate averages US$90 per barrel or more over the quarterly measuring period, according to the program fact sheet of March 2024.
- The Government of Alberta reported on September 22, 2026, that West Texas Intermediate averaged US$90.54 per barrel from August 18 to September 15, 2026, and that Alberta’s average gasoline price was $1.755 per litre on September 21.
- Finance Canada announced on September 22, 2026, legislation to hold the federal fuel excise tax at $0 per litre on gasoline and diesel until January 31, 2027, with half rates from February 1 and full rates from April 1, 2027.
Alberta’s fuel tax comes off because oil crossed a line the province set in advance
Nobody had to hold a vote for this one.
Alberta wrote the rule years ago. Oil averages US$90 or better over the measuring window, the tax goes to zero. Between US$80 and US$90 it drops part way. Under US$80 it’s back to the full $0.13. The province checks the average every quarter.
West Texas Intermediate averaged US$90.54 from Aug. 18 to Sept. 15. That’s US$0.54 over the line. So the tax comes off, the same way a thermostat kicks the furnace on. No bill required.
You can argue about the formula. Plenty of people did earlier this month, including us, back when Brent crossed US$100 and the rate didn’t move. But a rule you can read ahead of time beats a favour you have to wait for.
Ottawa’s pump relief needs a bill to last past January
Ottawa has a pause too. Credit where it’s due. The federal excise, $0.10 a litre on gas and $0.04 on diesel, has sat at zero since April 20.
Here’s the catch. On Sept. 22 the federal finance minister introduced legislation to keep it at zero until Jan. 31. Half rates in February and March. Full rates again April 1.
Introduced. Not passed.
So one level of government set a rule and let it run. The other wrote a bill, and now it has to get that bill through the House before anybody’s tank is sure of anything past January. One of those is a rule. The other is a favour with an expiry date.
The sign at your station is the part no law sets
The tax comes off the fuel. The price on the sign is still the station’s call.
Last time the whole $0.13 came off, in April 2022, stations in Edmonton and Calgary were reported dropping about $0.10 overnight, not the full amount. Wholesale prices move every day, up and down, and a single morning won’t tell you much. A week will.
So watch your usual station. Write the price down on Sept. 30. Check it again on Oct. 1 and again the week after. If the gap between that sign and the one down the road keeps growing, you’ll know something. The province runs a price gouging line at 1-877-427-4088.
The province took its $0.13 off the litre. Now we find out who keeps it.
Frequently asked questions
When does Alberta’s fuel tax suspension start and end?
The provincial fuel tax on gasoline and diesel, normally $0.13 per litre, is suspended effective October 1, 2026, through at least December 31, 2026, per Alberta Treasury Board and Finance.
How much will I save per litre?
The tax itself is $0.13 a litre, and GST is charged on top of that tax, so taking it off pulls about $0.1365 a litre out of the bill. On a 50 litre fill that is $6.83; on 60 litres, $8.19. The province estimated that Alberta’s average gasoline price of $1.755 per litre on September 21 would fall to roughly $1.625 per litre.
What triggered the fuel tax suspension?
Alberta wrote the rule years ago. Under the Fuel Tax Relief Program, the fuel tax falls to $0 per litre when West Texas Intermediate averages US$90 per barrel or more over the quarterly measuring period. WTI averaged US$90.54 from August 18 to September 15, 2026. Between US$80 and US$90 the tax drops part way; under US$80 it returns to the full $0.13. The province checks the average every quarter.
Is the federal fuel tax also paused?
Yes. The federal excise, $0.10 a litre on gasoline and $0.04 on diesel, has sat at zero since April 20. Finance Canada announced on September 22, 2026 that legislation will hold it at $0 per litre until January 31, 2027, with half rates from February 1 and full rates from April 1, 2027.
Does the suspension cover diesel and marked farm fuel?
The 13 cent reduction applies to clear gasoline and diesel at retail stations. For eligible producers buying marked farm fuel, which currently carries a 4 cent per litre provincial tax, the reduction is 4 cents a litre, per the Alberta government’s September 22, 2026 announcement.
What if my station does not lower its price on October 1?
The province says it will monitor pump prices to make sure the savings reach drivers. Suspected unfair pricing can be reported through Alberta’s Report a Rip-Off line at 1-877-427-4088. Businesses found guilty of price gouging can face court-imposed fines of up to $300,000 or as much as two years in jail.
