OPEC+ has decided not to add more oil to the market in October, delivering another layer of uncertainty for Canadian motorists already dealing with sharply elevated gasoline prices. The decision comes after six months of production increases and at a moment when renewed U.S.-Iran fighting has pushed crude prices higher and disrupted shipping through the Strait of Hormuz.
For Canada, the pressure is visible at service stations. The national average for regular gasoline stood at 174.9 cents a litre early September 6, compared with 153.3 cents a month earlier. OPEC+ is not solely responsible for that increase, but its decision removes one possible source of additional supply just as geopolitical risk is keeping the global oil market unusually tight.
OPEC+ Stops Its Six-Month Run of Output Increases
The September 6 decision keeps OPEC+ production policy unchanged for October. Seven producers involved in the latest monthly decisions—Saudi Arabia, Russia, Iraq, Kuwait, Algeria, Kazakhstan and Oman—agreed not to announce another increase. Their September production plan had completed the phased rollback of a 1.65-million-barrel-a-day voluntary supply reduction originally introduced in 2023.
That makes October an important turning point. OPEC+ had been gradually returning barrels to the market, offering consumers some hope that additional production might restrain prices. Instead, the group is now concentrating on the politically difficult task of reviewing members’ production capacities before establishing new 2027 quota baselines. Another broader layer of OPEC+ cuts also remains in place through the end of 2026. The seven countries are scheduled to meet again on October 4, meaning November supply policy remains unresolved.
Canadian Gasoline Has Already Become Much More Expensive
The OPEC+ announcement lands after a difficult stretch for Canadian motorists. CAA’s daily national price tracker put regular gasoline at an average of 174.9 cents per litre on September 6. That compared with 174.3 cents the previous day, 172.2 cents one week earlier and 153.3 cents one month earlier. A year earlier, the national average was 142.3 cents.
Those movements make even an ordinary fill-up noticeably more expensive for households that depend on driving. A family with two vehicles, a rural worker travelling long distances or a small contractor operating several vans feels the increase repeatedly rather than as a single expense. CAA recorded a recent one-month peak of 175.4 cents per litre on September 4. The OPEC+ freeze does not automatically mean another immediate increase, but it arrives with prices already close to that recent high.
The Bigger Immediate Problem Is the Middle East
Oil markets entered the OPEC+ meeting already under considerable pressure. Brent crude ended September 4 at $96.28 a barrel, while West Texas Intermediate settled at $91.48. Brent gained 7.6% over the week and WTI climbed nearly 10%, largely as renewed military exchanges between the United States and Iran revived concerns about the availability of Middle Eastern supply.
Shipping through the Strait of Hormuz remains particularly important. Preliminary data cited by Reuters showed only four commodity vessels transiting the waterway on one recent Thursday, well below a 10-day average of roughly 15. Iraq has managed to increase exports, reaching about 2.34 million barrels a day in August compared with approximately 1.35 million in July, but that has not erased the market’s geopolitical risk premium. For Canadian motorists, that means overseas military developments can quickly become a household-budget issue.
Why OPEC Decisions Reach Canadian Filling Stations
Gasoline prices are built from more than the cost of crude oil. Refining, transportation, retail margins, taxes, inventory conditions and competition between nearby stations all matter. Still, Natural Resources Canada identifies changes in global crude prices as one of the most important drivers of gasoline-price volatility because crude is the basic feedstock refiners need to manufacture gasoline.
Canada also participates in an interconnected North American fuel market. The country imported about 485,000 barrels a day of refined petroleum products in 2025, up 3% from the previous year. Roughly 79.6% of those imports came from the United States. Quebec, Ontario and British Columbia import transportation fuels such as gasoline, diesel and jet fuel alongside domestically produced supplies. As a result, a disruption that raises international crude or wholesale fuel prices can move through Canadian distribution networks even when the physical gasoline in a particular station was refined much closer to home.
Being an Oil-Producing Giant Does Not Guarantee Cheap Gas
There is an apparent contradiction in Canada paying high gasoline prices while producing enormous quantities of crude. Canadian crude oil and equivalent production actually reached a record average of 5.35 million barrels per day in 2025, up from 5.14 million in 2024. By December 2025, monthly production had climbed as high as 5.64 million barrels per day.
Much of that crude enters international markets rather than being reserved for Canadian motorists at a discounted domestic price. Canada exported about 4.3 million barrels per day of crude in 2025, with roughly 90% going to the United States. Canada also had 16 refineries capable of processing about 1.9 million barrels daily; refinery runs averaged roughly 1.6 million barrels per day in 2025. Geography matters as well. Some eastern refineries rely partly on imported crude because transporting western Canadian oil across the country is not always the most practical or economical option.
Ottawa Is Keeping a 10-Cent Tax Cushion in Place
The federal government has already intervened to prevent pump prices from being even higher. Ottawa originally suspended the 10-cent-per-litre federal excise tax on gasoline as energy costs climbed during the Middle East conflict. On September 2, Finance Minister François-Philippe Champagne announced that the suspension would be extended through January 31, 2027.
Under the government’s proposal, the tax would return at half its regular rate from February through March 2027 before returning to the full rate in April. The government estimates the extension provides approximately $2.9 billion in additional tax relief and brings the estimated total relief for the 2026-27 fiscal year to $5.3 billion. The measure is significant, but it cannot insulate drivers completely from global crude movements. A sufficiently large increase in wholesale fuel costs can quickly overwhelm a fixed 10-cent-per-litre tax reduction.
Gasoline Is Already Showing Up in Canada’s Inflation Numbers
Higher fuel prices are not confined to household transportation budgets. Statistics Canada reported that consumer prices rose 3.0% year over year in July 2026, while gasoline prices were 25.7% higher than a year earlier. Transportation costs overall rose 7.8%. By comparison, inflation excluding gasoline was 2.2%, illustrating how much energy was contributing to the headline figure.
The Bank of Canada is paying close attention. On September 2, it kept the overnight policy rate at 2.25% and specifically noted that the continuing Middle East conflict was keeping energy prices high. Sustained gasoline and diesel increases can spread beyond service stations because trucking, agriculture, construction, aviation and distribution all consume substantial amounts of fuel. A driver may notice the shock first on a roadside price board, but businesses can eventually face similar pressure when moving groceries, building materials and other goods around the country.
The Pain Will Not Be Equal Across Canada
A national gasoline average can hide large regional differences. CAA notes that local taxes, retail competition, sales volumes and station location all influence the price motorists ultimately pay. Refining and distribution systems also differ widely between provinces, so a move in global crude does not necessarily appear at every Canadian pump at the same time or in the same magnitude.
Canada’s fuel-import pattern helps explain some of those differences. In 2025, Quebec imported approximately 103,000 barrels per day of refined petroleum products, while Ontario imported about 36,000 and British Columbia roughly 34,000. Much of the supply flowing into the most populous provinces consists of transportation fuels. Local refinery maintenance, pipeline constraints or wholesale-market movements can therefore amplify—or occasionally soften—a global crude-price change. Two households thousands of kilometres apart may both be reacting to the same OPEC+ decision while seeing very different numbers on their neighbourhood signs.
OPEC+’s Freeze Is Less Powerful Than It Once Looked
Keeping quotas unchanged sounds like a straightforward restriction on supply, but the current oil market is considerably messier. OPEC+ members have recently been producing well below some agreed targets because the Middle East conflict has disrupted physical production and export routes. In that environment, announcing a higher quota does not guarantee that equivalent additional barrels will actually reach customers.
That distinction is crucial for understanding October. OPEC+ could theoretically authorize more production, yet transportation bottlenecks and geopolitical disruptions might prevent some of that oil from reaching world markets. Reuters reported that the producer group is therefore turning more attention toward establishing realistic production-capacity baselines for 2027. Sources had previously indicated that increases could be paused through the fourth quarter, although Sunday’s statement only confirmed October policy. For motorists, real barrels delivered to refiners matter more than an increase written into a production target.
What Canadian Drivers Should Watch Next
October’s OPEC+ policy is only one part of the equation. The next major decision is scheduled for October 4, when the seven producers will consider policy for November. Before then, developments around the Strait of Hormuz, U.S.-Iran military activity, refinery availability, inventories and international crude prices are likely to matter more to Canadian gasoline bills than almost any single domestic factor.
There is also room for prices to retreat if geopolitical fears ease. Oil’s recent rally has included a substantial risk premium, and analysts cited by Reuters noted that the latest escalation had not necessarily produced an equivalent new loss of physical Middle Eastern exports. Seasonal gasoline demand also typically softens after the summer driving period. For now, however, Canadian motorists are entering autumn with a national average near 175 cents a litre, crude near recent multi-week highs and OPEC+ declining to supply another scheduled increase. That combination leaves little margin for another international disruption.
