Canadian drivers have been receiving temporary federal fuel excise tax relief since April 2026, but the measure is not scheduled to last indefinitely.

Under the federal government’s announced extension, gasoline and diesel excise tax rates remain at zero through January 31, 2027. The regular rates would then return in two stages: half the normal rate in February and March, followed by the full rate in April.

For ordinary gasoline, that means the federal excise tax is scheduled to move from zero to five cents per litre on February 1, then to 10 cents per litre on April 1.

These changes could affect what motorists pay at the pump. However, the exact retail price will also depend on oil markets, refinery costs, distribution, competition, provincial taxes and other factors.

What is changing in Canada’s federal fuel excise tax?

The Department of Finance announced an extension of temporary federal fuel tax relief in September 2026.

The measure was originally introduced in April and subsequently extended through proposed federal legislation.

The federal government’s September 2 announcement establishes the following schedule.

Period	Federal excise tax on ordinary gasoline	Federal excise tax on diesel
Through January 31, 2027	0¢ per litre	0¢ per litre
February 1–March 31, 2027	5¢ per litre	2¢ per litre
From April 1, 2027	10¢ per litre	4¢ per litre

These are the announced federal rates and dates. The government introduced Bill C-38 to extend the relief, so readers should confirm the final legislative status before relying on a future rate change as legally finalized.

How much could a 50-litre gasoline fill-up change?

Consider a driver purchasing 50 litres of gasoline.

At a federal excise tax rate of zero, the federal excise-tax component is $0.

At five cents per litre, the component becomes $2.50.

At 10 cents per litre, it becomes $5.

Fill-up volume	0¢/L federal rate	5¢/L federal rate	10¢/L federal rate
40 litres	$0	$2.00	$4.00
50 litres	$0	$2.50	$5.00
70 litres	$0	$3.50	$7.00

These amounts represent the federal excise-tax component only. They do not represent the complete cost of filling a vehicle and do not include any additional effect that sales taxes may have on the retail price.

How much might a household pay over a year?

A family that purchases 120 litres of gasoline every month buys approximately 1,440 litres annually.

At 10 cents per litre, the corresponding federal excise-tax component would be $144 annually.

At five cents per litre, it would be $72 annually.

At a zero rate, the component would be $0.

This is a comparison of tax rates applied to a constant annual fuel volume. It is not a forecast of exactly how much that family will save or spend in 2027.

Actual fuel prices can rise or fall by substantially more than a few cents per litre because of market conditions unrelated to federal excise tax.

Why did Canada suspend the federal fuel excise tax?

The federal government introduced temporary fuel tax relief in April 2026 as part of its response to rising energy costs.

The ordinary federal excise tax on gasoline is 10 cents per litre, while diesel is normally subject to a four-cent rate.

The federal government said the suspension was intended to reduce cost pressures for households and sectors that rely heavily on fuel, including transportation, agriculture and construction.

In September, Ottawa announced an extended period of relief and a staged return to regular taxation.

The Department of Finance estimated that its fuel tax relief measures would provide $5.3 billion in total tax relief during the 2026–27 fiscal year.

That is a national government estimate, not a direct cash payment to individual motorists.

Does every driver save the same amount?

No. The potential excise-tax component depends on the quantity and type of fuel purchased.

A commuter driving a fuel-efficient compact car will generally purchase less gasoline than someone driving a large vehicle over the same distance.

Consider two hypothetical vehicles travelling 1,500 kilometres per month.

Vehicle	Assumed fuel consumption	Monthly fuel volume	Excise tax at 10¢/L
Compact car	6.5 L/100 km	97.5 litres	$9.75
Larger SUV	11 L/100 km	165 litres	$16.50

The fuel consumption values are hypothetical examples, not measured averages for all compact cars and SUVs.

In this comparison, the SUV’s higher fuel use produces a larger excise-tax amount.

It also means the larger vehicle is exposed to greater changes in underlying gasoline prices.

Why the federal tax change does not predict the pump price

Gasoline prices reflect several cost components, including crude oil, refining, distribution, retail margins and taxes.

The federal excise tax is only one part of that total.

Suppose gasoline costs $1.45 per litre one week and $1.55 the next.

The 10-cent increase might be caused by changing wholesale prices, tax changes, or a combination of factors.

Without a breakdown, consumers cannot assume that every price increase is caused by a new tax.

Likewise, a suspension of 10 cents per litre in federal excise tax does not guarantee that the retail price will fall by exactly 10 cents at every station.

Federal fuel excise tax versus provincial fuel taxes

Federal fuel excise tax and provincial fuel taxes are separate.

Provincial governments can apply different fuel taxation rules and may adjust their own rates independently of Ottawa.

This is particularly relevant in Alberta, where provincial fuel tax policy has changed during 2026.

A federal rate increase in 2027 should therefore not be confused with a simultaneous provincial rate increase.

When comparing gasoline prices between provinces, motorists need to consider the combined effect of federal taxes, applicable provincial taxes and market prices.

What about diesel drivers?

Diesel fuel is subject to a lower ordinary federal excise-tax rate than gasoline.

The government’s schedule provides for a two-cent-per-litre rate in February and March 2027, followed by the ordinary four-cent rate in April.

For a vehicle purchasing 100 litres of diesel, the federal excise-tax component would be $2 at the half rate and $4 at the full rate.

For commercial vehicles that purchase thousands of litres each month, the same cents-per-litre difference becomes a larger operating-cost consideration.

However, fuel tax treatment for particular commercial uses can involve additional rules, and businesses should confirm the treatment relevant to their operations.

Could higher fuel costs affect grocery and delivery prices?

Transportation costs are one input into the price of moving food, manufactured goods and other products.

Higher diesel or gasoline costs can put pressure on distribution expenses, particularly for businesses that operate large vehicle fleets.

But there is no simple formula that converts a one-cent fuel tax increase into a specific increase in grocery prices.

Retail food prices also reflect labour, rent, packaging, exchange rates, commodity costs and competition.

For households tracking food expenses, Maple Curiosity’s Alberta Grocery Prices 2026 guide provides a broader look at the factors affecting shopping costs.

How can drivers estimate their own exposure?

Drivers do not need to predict gasoline prices to understand their potential exposure to the tax change.

A simple calculation can help:

Fuel purchased in litres × excise tax per litre = excise-tax component.

For example, purchasing 180 litres of gasoline in a month produces a $9 federal excise-tax component at five cents per litre and an $18 component at 10 cents per litre.

That is a $9 difference between the two tax rates before considering any other taxes or market-price changes.

Recording actual fuel purchases for two or three months provides a more useful estimate than assuming every household drives the same distance.

Ways to reduce fuel spending without relying on tax changes

The federal tax schedule is outside an individual driver’s control, but fuel consumption is partly influenced by vehicle use and maintenance.

• Combine several errands into one trip where practical.
• Maintain appropriate tire pressure.
• Avoid unnecessary idling.
• Compare fuel prices when filling up without making an expensive detour.
• Check whether driving, transit or carpooling is more economical for frequent journeys.
• Track actual litres purchased rather than estimating fuel costs from memory.

Drivers should also consider vehicle insurance, maintenance and parking when evaluating the total cost of transportation.

What should Canadians watch before February 2027?

The key items are the final status of Bill C-38, the federal government’s published excise tax rates and the direction of actual retail fuel prices.

Drivers should not assume that an announced future tax schedule is identical to a legally completed change until the necessary legislative process is confirmed.

Provincial fuel tax changes may also affect the combined retail price.

Bottom line

Canada’s announced federal fuel excise tax plan calls for zero rates through January 2027, half rates in February and March, and a return to ordinary rates in April.

For gasoline, the scheduled rates are zero, five and 10 cents per litre across those stages. For diesel, they are zero, two and four cents.

Understanding these figures helps households and businesses estimate the tax component of their fuel costs, but it does not predict future pump prices.

The most practical approach is to track personal fuel consumption, distinguish federal and provincial taxes, and confirm the legislation and current rates before making longer-term budget assumptions.
