Calgary gas prices have climbed back above $1.70 a litre less than a week after Alberta suspended its provincial fuel tax, sharply reducing the immediate benefit drivers were supposed to see at the pump.
The reported Calgary average for regular gasoline reached 171.5 cents per litre on October 7, according to GasBuddy data, after falling to about 150 cents per litre on October 1 when the tax suspension took effect.
That represents an increase of roughly 21.5 cents per litre in six days.

Calgary gas prices move higher after October 1 drop
Alberta suspended the full provincial fuel tax at 12:01 a.m. on October 1 as part of the province’s fuel-tax relief measures.
The measure removed 13 cents per litre from the provincial fuel tax charged on regular gasoline and diesel.
The relief is scheduled to remain in place until at least December 31, 2026, although the province can review the rate again before the program ends.
For a driver filling a 60-litre vehicle tank, the direct tax reduction is worth $7.80 before any changes in wholesale or retail prices.
However, the early decline in Calgary pump prices did not last.
By October 7, the reported city average had risen about 8.5 cents per litre above the October 1 level, meaning the tax reduction was more than offset by other price movements.
Why the tax cut does not guarantee a fixed pump price
The provincial fuel tax is only one component of the final price motorists pay.
Retail prices also reflect crude oil costs, refining margins, wholesale gasoline prices, transportation expenses, local competition and the margins set by individual stations.
Alberta’s government says its fuel-tax system is reviewed quarterly using average West Texas Intermediate oil prices.
Under the program’s standard framework, the provincial tax is suspended when the qualifying oil-price average reaches $90 or more per barrel.
Partial tax rates can apply when the average falls between $80 and $89.99, while the full 13-cent tax can return when the average drops below $80.
The province’s fuel-tax information also makes clear that the tax is included in the per-litre price paid at the pump.
That means removing the tax creates room for a lower retail price, but it does not control how quickly stations change prices or how much of the reduction appears on a particular day.
Large differences between Calgary stations
Drivers have reported substantial differences between stations across Calgary during the week following the tax suspension.
Prices can change at different times depending on when a station receives new fuel, updates its retail margin or responds to nearby competitors.
GasBuddy’s citywide figures are based on reported station prices and should be treated as an average rather than a guaranteed price at every location.
That makes comparison shopping especially important while prices are moving rapidly.
Drivers may find lower prices at warehouse-club stations, independent retailers or stations in areas with heavier competition, although availability and lineups can vary.
Province says it is monitoring pump prices
The Alberta government said it would monitor pump prices to ensure the fuel-tax savings are passed on to consumers.
Officials have also warned that businesses could face action if they are found to be engaging in unlawful price gouging.
The monitoring comes as the tax suspension has produced a visible gap between the expected 13-cent reduction and the subsequent movement in Calgary’s average price.
A rise in wholesale or crude-related costs could explain part of the increase, but the available citywide figures do not by themselves establish why every station moved higher.
The key question for drivers will be whether Calgary prices settle at a lower level once the post-tax-change adjustments work through the market.
What Calgary drivers should watch next
The next several days should show whether the October 7 increase was temporary or part of a broader upward cycle.
Drivers should compare prices shortly before filling up because station-to-station differences can be significant.
They should also remember that the tax relief applies to the provincial fuel-tax portion and does not protect motorists from changes in oil prices, refining costs or retail margins.
If the provincial program remains suspended through December 31, the maximum direct saving remains 13 cents per litre compared with a fully reinstated Alberta fuel tax.
For now, Calgary’s reported average shows that a tax cut can be quickly overwhelmed by movements elsewhere in the fuel market.
