Oil has crossed a threshold that tends to get attention far beyond commodity trading desks. Brent crude, the international benchmark, moved above US$100 a barrel on September 9 for the first time since late July as renewed fighting in the Middle East intensified concerns about disrupted supplies and shipping routes.

For Canadians, the significance is less about the round number itself than what could come next. Gasoline prices were already sharply higher than a year earlier, refinery margins remain elevated, and transportation costs have been feeding into inflation. Canada is also a major oil producer, meaning higher prices can lift energy-sector revenues and provincial finances. But for households paying for gasoline, flights, deliveries or heating oil, another prolonged stretch of expensive crude could make an already difficult affordability picture harder.

The $100 Threshold Reflects a Much Bigger Supply Problem

Brent crude pushed above US$100 a barrel on September 9, its first move through that level since July 24. U.S. West Texas Intermediate remained lower, trading around the mid-US$90s, so the headline does not mean every major oil benchmark is above US$100. Brent matters globally because it influences the pricing of enormous volumes of internationally traded crude and refined petroleum products.

The latest increase is tied primarily to renewed disruption in the Middle East rather than a sudden explosion in global consumer demand. Oil traffic through the Strait of Hormuz, one of the world’s most important energy corridors, has been severely restricted during the conflict. The International Energy Agency said in August that Gulf production remained 8.3 million barrels a day below pre-war levels in July. That makes markets particularly sensitive to attacks on tankers, pipelines, refineries and alternative shipping routes. When there is less room for disruption, even another relatively small escalation can produce an outsized price reaction.

Canadian Drivers Are Starting From an Expensive Base

For motorists, the latest crude increase is arriving after months of unusually expensive fuel. Statistics Canada reported that gasoline prices were 25.7% higher in July than a year earlier and increased 3.6% from June alone. In Toronto, regular gasoline was expected to average about 186.9 cents a litre on September 9, substantially above the levels motorists were seeing at the beginning of 2026.

A US$100 barrel does not translate mechanically into a specific Canadian pump price. Crude is only one component. Refining costs and margins, transportation, retail margins, taxes, local competition and the Canada-U.S. exchange rate all matter. The Competition Bureau has historically estimated crude oil at roughly 40% of the average Canadian pump price, although that share changes considerably with market conditions. The current complication is that refining margins have also been elevated. That means falling crude alone would not necessarily deliver immediate relief if gasoline and diesel supplies remain tight.

Household Budgets Have Less Room to Absorb Another Fuel Shock

Gasoline is not a marginal expense for many families. Statistics Canada’s most recent comprehensive household-spending data showed Canadians spending an average of $2,567 annually on gasoline and other fuels in 2023. Total transportation spending averaged $12,090, making transportation one of the three largest household consumption categories alongside shelter and food.

Those averages can hide how painful another increase becomes for households with limited flexibility. Workers with long commutes, families managing multiple vehicles and people living in areas with limited public transportation cannot necessarily respond to a price spike by simply driving less. Earlier Statistics Canada data also showed gasoline and fuel spending rising across every income group between 2021 and 2023, with the second-lowest income quintile recording the fastest increase at 45.8%. When fuel absorbs another $10 or $20 from a weekly budget, the adjustment may show up somewhere completely unrelated to driving—fewer restaurant meals, delayed purchases or less money available for savings.

Diesel Costs Can Travel Through the Price of Almost Everything

The household exposure extends well beyond filling a personal vehicle. Diesel powers much of the trucking system that moves groceries, construction materials, manufactured products and other goods between warehouses, distribution centres and stores. Statistics Canada’s Food Price Data Hub reported diesel fuel prices up 45.1% year over year in June 2026, illustrating how large the energy shock had already become before Brent’s latest return above US$100.

That does not mean a 10% jump in diesel automatically produces a comparable increase in grocery prices. Transportation is only one component of the final cost of food, and retailers or suppliers sometimes absorb higher expenses through their margins. Still, the Bank of Canada has identified fuel surcharges, shipping disruption and other upstream costs as channels through which the Middle East conflict can eventually reach consumer prices. Grocery inflation was already 3.1% in July, marking an 18th consecutive month in which food purchased from stores rose faster than overall consumer prices.

Airfares Show How Energy Costs Can Spread Beyond the Highway

Air travellers have already received another example of petroleum costs appearing in everyday spending. Statistics Canada reported that air transportation prices were 12% higher in July than a year earlier, accelerating from 9.6% in June. The agency specifically identified higher jet-fuel costs as one contributor to the increase.

Airlines do not price tickets solely according to the cost of fuel. Demand, route competition, aircraft availability, wages, airport fees, exchange rates and how far in advance a ticket is purchased all play major roles. Nevertheless, jet fuel is a significant operating expense, so sustained petroleum-market pressure can make it harder for carriers to keep fares down. That matters particularly in Canada, where long distances make aviation essential for many communities and business routes. Statistics Canada’s household survey showed Canadians spending an average of $1,158 on air travel in 2023. Another extended oil spike therefore reaches beyond commuters and road trips; it can affect family visits, business travel and holiday budgets as well.

Heating-Oil Households Face a Different Kind of Exposure

September’s oil increase is also occurring as colder weather approaches. The consequences will not be identical across Canada because most households do not heat their homes with petroleum. Natural gas and electricity have their own supply-and-pricing dynamics. Heating-oil users, however, are much more directly exposed to changes in international petroleum markets.

That exposure is concentrated geographically. Canada Energy Regulator data show that about 19% of Atlantic Canadian households still used heating oil in 2023, compared with roughly 2% outside the region, although oil use has been declining as heat-pump adoption grows. The affordability implications can be serious. Statistics Canada estimated that 822,000 Canadian households were experiencing energy poverty in the 2021 Census, with rates exceeding 10% across Atlantic provinces. Separate 2023 data found about 15% of households had reduced or forgone basic necessities for at least one month to cover an energy bill. A sustained autumn oil surge would therefore reach some households already making difficult trade-offs.

The Inflation Problem Is Back in the Bank of Canada’s Spotlight

The latest surge comes at an awkward moment for monetary policy. The Bank of Canada held its policy rate at 2.25% on September 2 and said headline inflation had remained around 3% largely because gasoline prices were persistently high. Inflation excluding gasoline was only 2.2% in July, while the Bank’s preferred measures of underlying inflation remained close to 2%.

That distinction matters. Central banks generally have little reason to react aggressively to a temporary gasoline spike they cannot control. The problem begins if expensive energy persists long enough to raise transportation, manufacturing and other business costs, influence wages or alter inflation expectations. The Bank has explicitly warned that the longer high oil prices and elevated refining margins persist, the greater the danger of spillovers into other goods and services. Its July projections had assumed substantially lower oil prices than today’s level. Brent above US$100 does not automatically mean another rate increase, but prolonged strength would make the inflation outlook more complicated ahead of the Bank’s October 28 decision.

The Canadian Dollar Is Not Providing Its Old Cushion

Canada’s status as a major oil exporter once created a useful partial offset for consumers. Rising oil prices frequently strengthened the Canadian dollar because stronger export revenues increased demand for Canadian currency. Since oil is generally priced internationally in U.S. dollars, a stronger loonie could reduce some of the Canadian-dollar cost of imported petroleum and other foreign goods.

That relationship has weakened. The Bank of Canada noted earlier this year that the Canadian dollar remained broadly unchanged during an earlier oil-price surge, unlike historical episodes when the currency tended to appreciate. It attributed part of the change to a less investment-intensive Canadian energy industry and other structural factors. On September 9, Reuters reported the loonie at roughly C$1.377 per U.S. dollar even as Brent crossed US$100. A currency that fails to strengthen substantially alongside oil gives consumers less protection: more of the global petroleum-price increase can show up directly in Canadian fuel costs rather than being partly absorbed through exchange-rate appreciation.

Canada’s Oil-Producing Regions Stand to Gain at the Same Time

The national picture is unusually complicated because Canada is both a large petroleum consumer and one of the world’s major producers. Canadian crude oil and equivalent production averaged a record 5.35 million barrels a day in 2025. Alberta accounted for almost 84% of that production, while Saskatchewan and Newfoundland and Labrador were also significant contributors. Canada exported 4.3 million barrels a day of crude in 2025, worth about $140 billion.

Higher realized oil prices can therefore lift producer revenue, profits, investment capacity and government royalties, depending on production levels, benchmark differentials and exchange rates. Alberta’s 2026-27 budget estimated $13.2 billion in non-renewable resource revenue using much lower oil-price assumptions, while Newfoundland and Labrador expected oil royalties to provide about 19% of provincial revenue and built its budget around a US$79 Brent assumption. Yet the benefits do not cancel a household’s gasoline bill. Even residents of producing provinces buy fuel at market-linked prices, creating the familiar Canadian paradox of governments and producers benefiting from an oil rally while motorists pay more.

What Happens Next Matters More Than the Number $100

There is nothing economically magical about US$100. What matters is whether oil stays there, falls quickly or climbs substantially further. The central variables are physical: how much petroleum can move through the Strait of Hormuz and alternative routes, whether damaged production and refining capacity returns, how quickly inventories can rebuild, and whether global demand weakens enough to offset lost supply.

Forecasts have already demonstrated how rapidly those assumptions can become outdated. In August, the U.S. Energy Information Administration expected Brent to decline toward an average of US$78 in the fourth quarter as Hormuz traffic gradually recovered. The International Energy Agency, meanwhile, projected global oil supply would decline by 4.3 million barrels a day in 2026 and described refining margins as exceptionally high. September’s renewed attacks have introduced another layer of uncertainty. For Canadian households, durable relief will likely require more than oil briefly slipping below a psychological threshold. Normalized shipping, improving petroleum-product supplies, narrower refinery margins and a stable Canadian dollar would provide a much stronger signal that the pressure is genuinely easing.
