Toronto drivers are facing a striking divide at the pumps, with diesel prices forecast to reach nearly $2.40 per litre while regular gasoline remains significantly cheaper. The widening difference is creating fresh financial pressure for diesel-powered vehicle owners, commercial truck operators, and businesses that depend on transportation.
According to forecasts from Canadians for Affordable Energy, diesel prices in Toronto are expected to remain at 239.9 cents per litre from November 8 through November 10, 2026, compared with 162.9 cents for regular gasoline. That represents a substantial 77-cent difference for every litre purchased.
While gasoline drivers are benefiting from recent price declines, diesel users face a different reality. The disparity raises questions about fuel markets, transportation costs, and how much of the additional burden could eventually reach Canadian consumers.
Toronto’s Diesel Price Forecast Reveals a 77-Cent Difference
The headline figure is 239.9 cents per litre, the diesel price projected for Toronto by Canadians for Affordable Energy for November 8 through November 10. Regular gasoline is forecast at 162.9 cents over the same period. The difference is exactly 77 cents per litre, making diesel roughly 47 per cent more expensive on a volume-for-volume basis. The projection comes from energy analyst Dan McTeague’s price-tracking service and describes an expected market price, not a guaranteed price at every station.
That distinction matters when a driver pulls off the road to fill up. Individual retailers can post different prices, and forecasts may change as suppliers and stations respond to market movements. The figures also compare fuels sold for different engines: a diesel vehicle cannot simply switch to cheaper regular gasoline. For motorists who already own diesel vehicles, however, the forecast provides a clear picture of the premium they face when planning the next fill-up.
Gasoline Prices Have Fallen Sharply While Diesel Remains Expensive
The frustration for diesel drivers is sharpened by what has happened to gasoline. En-Pro data published by CityNews show regular gas in Toronto at 177.9 cents per litre on November 3, dropping to 166.9 cents the next day and 160.9 cents by November 6. The forecast then put gasoline at 162.9 cents on November 8, following a modest rebound. For families driving gasoline-powered cars, those changes translate into noticeable savings each time the tank needs filling.
Diesel has not followed the same short-term path in the forecast from Canadians for Affordable Energy. Its projected price stays near $2.40 per litre through November 10, even as regular gasoline holds closer to $1.63. That creates an unusually visible divide at service stations where both grades are displayed side by side. It also illustrates an important point about energy markets: the price of crude oil alone does not determine what consumers pay for every refined fuel.
A Full Tank of Diesel Could Cost Drivers Nearly $240
For the owner of a diesel pickup or work van, the 77-cent difference becomes more tangible when a tank is filled. At the projected Toronto prices, 60 litres of diesel would cost $143.94, compared with $97.74 for the same quantity of regular gasoline. That is a $46.20 gap on one purchase. A 100-litre purchase would cost $239.90 for diesel, versus $162.90 for gasoline, a $77 difference before any additional expenses.
Those comparisons illustrate price per litre, not the running costs of identical vehicles. Natural Resources Canada explains that comparable diesel vehicles can use 15 to 30 per cent less fuel because of engine efficiency and diesel’s greater energy content. Even so, a 47 per cent pump-price premium can overwhelm much of that advantage. Actual cost per kilometre depends on the model, driving conditions and load. For a household or contractor evaluating expenses, fuel consumption matters as much as the number displayed on the pump.
Why Diesel Prices Are Staying High Despite Cheaper Gasoline
Diesel and gasoline come from crude oil, but they do not share an identical market. Refiners process crude into several products, including gasoline, diesel and jet fuel. The prices of those products respond to their own supplies, inventories and demand. The U.S. Energy Information Administration says diesel costs reflect crude oil, refining margins, distribution, retail expenses and taxes. A fall in the cost of one component does not guarantee an equivalent decline in every fuel grade.
In 2026, the diesel side of that equation has been particularly strained. The EIA reported in September that reduced refining activity in Russia, China and the Middle East had tightened international supplies of distillates, the category that includes diesel. Higher wholesale premiums for diesel added to the pressure even where crude prices were already elevated. For Toronto drivers, that helps explain why a gasoline price reduction can arrive without a matching diesel discount. The gap reflects broader markets, not necessarily a single local retailer’s decision.
Refineries Are Shifting Production as Diesel Becomes More Valuable
The supply strain has been strong enough to change what refineries produce. In an analysis published November 5, the U.S. Energy Information Administration said American refiners had shifted part of their output away from gasoline toward middle distillates, including diesel and jet fuel. Gasoline accounted for less than 45 per cent of refinery yields on average from January through August 2026, below the typical 45 to 50 per cent range. Distillate yields, meanwhile, ran above their recent five-year average.
That shift might sound like good news for diesel buyers, but it also shows just how powerful the market incentive has become. Refiners make more of a product when its margins are attractive, yet they cannot transform their output mix without technical limits. The EIA identifies constrained global distillate supplies as a major reason for unusually strong margins. Additional North American production may ease pressure over time, but it does not mean the Toronto pump-price gap must close immediately.
Ontario’s Official Fuel Data Confirms the Large Price Gap
Daily forecasts are only one window into diesel costs. Ontario also publishes a weekly motor-fuel survey using retail prices gathered across the province. Figures republished from its November 2 survey put Toronto diesel at approximately 251.2 cents per litre and regular gasoline at 177.9 cents. That works out to a 73.3-cent gap, already large before the November 8 forecast placed the difference at 77 cents. The two sets of figures should not be treated as if they were recorded simultaneously.
The earlier survey also shows how uneven prices can be across the GTA. Separate Toronto East and Toronto West measurements produced diesel averages of 252.7 and 249.7 cents, respectively. Those regional averages offer useful context, but no driver is guaranteed either amount at a particular pump. Comparing a weekly snapshot with a short-term forecast requires attention to dates, locations and methodology. For consumers, the message is consistent even when the exact number shifts: diesel carries a steep premium.
Trucking Companies Face Growing Pressure From Diesel Costs
The consequences reach well beyond private diesel vehicles. Delivery trucks, long-haul tractors and many service vehicles depend on diesel to keep businesses moving. Statistics Canada reported that prices for truck transportation were 9.5 per cent higher in the second quarter of 2026 than a year earlier, amid increased global energy costs. Those were industry-wide figures rather than a direct measure of Toronto’s latest diesel forecast, but they show how fuel pressure can affect freight operations.
A smaller delivery firm cannot always absorb a higher fuel bill without changing something else. It may reduce unnecessary trips, renegotiate rates or add fuel charges to customer invoices. Statistics Canada also found that, among transportation and warehousing businesses expecting input costs to be an obstacle in the third quarter, 68.1 per cent identified energy costs as a concern. For the driver making repeated deliveries across the GTA, pennies per litre accumulate into meaningful expenses over hundreds of kilometres.
Higher Diesel Costs Could Reach Consumers Through Delivery Fees
Consumers may encounter the impact of expensive diesel without owning a diesel vehicle. Shipping companies commonly adjust fuel surcharges as energy prices change, making transportation costs more visible on invoices. FedEx Canada listed a 55.5 per cent surcharge for domestic Express and Ground services for November 2 through November 8, with a 53.5 per cent rate scheduled for the following week. FedEx says its domestic formula follows a national diesel price index, not Toronto’s daily forecast.
Canada Post offers another example. It listed a 49 per cent published fuel surcharge on domestic parcel services for November 2 through November 8, reduced to 41.6 per cent for eligible parcels under temporary relief. These percentages are surcharges applied under each provider’s pricing rules, not the percentage increase in the total cost of every shipment. Still, they show how fuel expenses can enter the final bill for a business mailing products or a customer arranging deliveries.
Fuel Taxes Are Not the Main Reason Diesel Costs So Much More
Fuel taxes are part of every pump price, but Ontario’s tax structure does not explain a 77-cent difference. The province currently levies nine cents per litre on both clear diesel and regular unleaded gasoline. Federal excise taxes on both fuels are temporarily suspended, with legislation passed in October extending that relief through January 31, 2027. The federal rates would otherwise be 10 cents per litre for gasoline and four cents for diesel. Ontario’s harmonized sales tax also applies to purchases, increasing the dollar amount of tax paid on a higher-priced litre.
Those details matter because a large price gap can invite assumptions that diesel is being singled out by a special provincial tax. The main difference is instead rooted in the prices of the refined products themselves, with sales tax adding to the total. Ottawa has scheduled a partial return of federal fuel excise taxes in February 2027, but that change will not by itself settle the question of diesel supply and demand.
Winter Demand Could Keep Diesel Prices Elevated in the Months Ahead
The approaching winter adds uncertainty to an already strained market. Diesel and heating oil belong to the same broad family of distillate fuels, so colder weather and heating demand can intensify competition for supplies. In its October outlook, the U.S. Energy Information Administration expected East Coast distillate inventories to remain unusually low through the winter. It also anticipated gradual easing in diesel prices as crude costs decline and inventories recover, although that is a U.S. outlook, not a guaranteed Toronto pump-price prediction.
In the meantime, drivers have more control over litres consumed than over wholesale prices. Natural Resources Canada recommends gentle acceleration, steady speeds, less unnecessary idling and regular tire-pressure checks. Its guidance says adopting fuel-efficient driving techniques can reduce consumption by as much as 25 per cent, depending on conditions. For businesses, reviewing routes and tracking fuel use may also help. Whether Toronto’s 77-cent gap narrows will ultimately depend on a sustained change in diesel supply, demand and refining margins.
