Diesel prices are becoming one of the clearest signs of how a global energy shock can travel all the way to a Canadian filling station. For September 21 and 22, Vancouver diesel is forecast at 289.9 cents per litre, while Toronto is expected to sit at 259.9 cents — roughly 30 cents less but still extraordinarily expensive by recent standards.
The pressure is no longer being driven by crude oil alone. Disrupted fuel exports, attacks on refining infrastructure, unusually low distillate inventories and limited spare refinery capacity have turned diesel itself into the scarce commodity. That distinction matters for Canada, where trucking, construction, farming and goods distribution remain heavily exposed to diesel costs. Global supply indicators increasingly suggest the problem will not disappear quickly, with tight inventories and elevated market risks potentially stretching well into 2027.
Vancouver Is Once Again at the Expensive End of the Market
The latest day-ahead forecasts from Canadians for Affordable Energy put Vancouver diesel at 289.9 cents per litre for September 21 and September 22. Toronto is forecast at 259.9 cents. The roughly 30-cent gap means a hypothetical 500-litre purchase would cost about $1,449.50 in Vancouver compared with $1,299.50 in Toronto — a $150 difference before considering any fleet discounts or commercial purchasing arrangements.
The Vancouver figure is not simply a theoretical warning. Kalibrate Canada’s daily pump-price data placed automotive diesel in Vancouver at 302.2 cents per litre on September 18, demonstrating that the city has already experienced prices above the $3 mark during the current disruption. The two data sources use different methodologies and timing, so their figures should not be treated as directly interchangeable. Together, however, they show the same underlying reality: diesel on the West Coast has moved into price territory that would have seemed exceptional only a short time ago.
Vancouver’s Price Premium Has Several Layers
Global diesel scarcity explains much of the recent surge, but it does not explain why Vancouver remains considerably more expensive than Toronto. Natural Resources Canada lists motor-fuel taxes on diesel in the Vancouver area at 27.5 cents per litre, compared with 9 cents in Ontario. Metro Vancouver’s figure includes an 18.5-cent TransLink levy alongside provincial components. British Columbia eliminated its consumer carbon tax in April 2025, so that should not be confused with the motor-fuel taxes that remain.
There are also structural supply differences. Kalibrate has identified limited West Coast refining capacity, competition for imported refined products and British Columbia’s low-carbon fuel requirements as factors affecting regional prices. Vancouver therefore entered the global diesel shortage with less room for error than some Central Canadian markets. Ottawa has temporarily removed the federal diesel excise tax, normally four cents per litre, but even that relief has been overwhelmed by much larger changes in wholesale fuel and refining costs.
This Is a Diesel Shortage, Not Simply an Oil-Price Story
A barrel of crude oil cannot be poured directly into a transport truck. It has to pass through a refinery capable of producing diesel that meets required specifications, and that refining stage has become a critical bottleneck. The U.S. Energy Information Administration says global distillate production is expected to remain below year-earlier levels in the coming months after significant supply losses from the Middle East, Russia and China.
The geopolitical disruptions are unusually concentrated in regions important to refined-fuel trade. Middle Eastern conflicts have constrained production and shipping routes, while attacks on Russian oil infrastructure have damaged refinery operations. Russia has also maintained restrictions on diesel exports as it protects domestic supplies. Reuters reports that the combined disruptions have stranded or removed large volumes from normal international trade. That is why diesel prices can remain elevated even when crude prices occasionally fall: available refinery output, inventories and shipping access matter just as much as the price of the raw barrel.
Inventories Show How Little Cushion the Market Has Left
One of the strongest warnings is coming from storage data. U.S. distillate inventories stood at approximately 107.9 million barrels for the week ending September 11. Reuters reported that this was the lowest level for that point in September since the EIA’s comparable records began in 1982. EIA’s September outlook goes further, forecasting inventories below the recent five-year range through much of 2027.
The weakness is not confined to North America. Reuters reported that diesel inventories in the Amsterdam-Rotterdam-Antwerp trading hub were 16% below their five-year average in July. Singapore’s recent total distillate inventories were running around 8.2 million barrels, below the 2025 average of roughly 9.6 million. Even the storage-leasing market is flashing an unusual signal: available diesel tank capacity in North America and the Caribbean is rising because traders have less fuel to place in storage. In a well-supplied market, empty tanks would normally be easier to fill.
Refiners Are Being Paid Record Amounts to Make Diesel
Refining margins illustrate just how valuable diesel has become. The U.S. diesel crack spread — broadly the difference between the value of diesel and the crude oil from which it is produced — hit a record $118.62 per barrel on September 14, according to Reuters. S&P Global has documented similarly extreme conditions in Europe, where Northwest European physical diesel reached a record $1,642.25 per metric ton on September 15.
Those margins provide refiners with a powerful incentive to maximize diesel production, but there is a physical ceiling to what plants can do. S&P Global reported that U.S. refineries have already been operating at high utilization rates, leaving few quick options for materially expanding output. Maintenance, mechanical failures or new geopolitical disruptions could therefore have an outsized effect. High margins should eventually encourage more production wherever spare capacity exists, but building inventories back from unusually depleted levels takes time. That is one reason current shortages cannot necessarily be solved merely by keeping existing refineries running harder.
Canada’s Freight Economy Feels Diesel Prices Quickly
For a household that does not own a diesel vehicle, the surge can seem distant. Canada’s transportation data show why it is not. Statistics Canada reported that truck-transportation prices in the second quarter of 2026 were 9.5% higher than a year earlier and 5.3% higher than in the first quarter. Diesel prices paid to producers were up between 40.3% and 58.8% year over year in July, depending on the region.
Energy was also the most frequently cited input-cost problem among transportation and warehousing businesses expecting cost pressures. Real-world surcharge systems show how those costs move through the supply chain. Trans BC Freightways, for example, listed a 58% fuel surcharge for September based on a Vancouver diesel reference price of $2.50 per litre, compared with 28% in September 2025. When fuel becomes this expensive, carriers can consolidate trips, negotiate new rates or add surcharges, but ultimately some of the increase can reach retailers, manufacturers and consumers.
Autumn and Winter Could Make the Tight Market Even More Difficult
The calendar is becoming another problem. Distillate demand typically rises during the autumn agricultural harvest because diesel powers farm machinery and trucks carrying crops. Refinery output, meanwhile, can temporarily decline as plants enter seasonal maintenance. The EIA has noted that U.S. distillate consumption historically increases during the fall, with additional winter demand coming from heating oil, which belongs to the same broad family of refined products as diesel.
That means the current shortage is arriving before a period when the system normally needs a larger inventory cushion. Reuters reports that industry participants expect global diesel supplies to remain tight through the winter, particularly if Middle Eastern exports remain constrained or Russian export restrictions continue. An unexpected refinery shutdown would add further risk. The seasonal pattern does not guarantee continuously rising pump prices — energy markets can reverse quickly — but unusually low inventories make the market more sensitive to disruptions that might have been absorbed more easily in a normal year.
China and Falling Crude Prices Could Eventually Provide Relief
There are potential escape valves. China sharply increased refined-fuel exports in August after earlier restrictions were eased. Reuters reported Chinese diesel exports of approximately 1.33 million tonnes for the month, up 42.1% from a year earlier and the highest since March 2024. Sustained Chinese exports would put additional barrels into a market searching aggressively for replacement supply.
The EIA also expects the broader oil market to improve during 2027 as Middle Eastern production recovers and global inventories rebuild. Its September forecast has Brent crude averaging about US$74 a barrel in 2027, down from around US$91 in 2026. That would remove one component of diesel’s current price pressure. The catch is that cheaper crude does not automatically mean an immediate normalization of diesel. Refined-product inventories must also recover, damaged or idled refining capacity must return, trade routes must stabilize and exceptionally high crack spreads must decline. Those processes can lag behind movements in crude oil itself.
The 2027 Outlook Is About Tightness, Not a Permanent $2.90 Price
The forecast for a global diesel shortage lasting into 2027 should not be interpreted as a prediction that Vancouver will remain at exactly $2.90 per litre or Toronto at $2.60 for the next year. Daily retail prices will continue reacting to crude markets, refinery conditions, exchange rates, regional taxes, inventories and geopolitical developments. The warning is that the underlying supply cushion is expected to remain unusually thin.
Canada has already extended temporary federal fuel-tax relief in recognition of those pressures. The federal excise tax on diesel is scheduled to remain at zero through January 31, 2027, rise to two cents per litre for February and March, and return to its normal four-cent rate on April 1. At the same time, EIA expects distillate inventories to remain below recent historical norms through much of 2027. For Canadian drivers and businesses, that combination points to continued vulnerability: prices may retreat from today’s extremes, but another disruption could still translate into unusually fast and expensive moves at the pump.
