Ontario motorists are waking up to another sharp increase at the pumps, with regular gasoline in Toronto and much of the GTA climbing roughly six cents per litre on Saturday after a similarly large increase Friday. Some price trackers put regular gasoline around 191.9 cents per litre, meaning Toronto has moved approximately 13 cents higher in only two days.
The timing is particularly noticeable because the latest increase is being linked primarily to wholesale gasoline costs rather than a matching overnight surge in crude oil. Terminal prices, refinery activity and North American gasoline-market conditions are all playing a role. The increases are also far from uniform across Ontario, with some communities experiencing significantly different changes depending on their regional supply market.
A Two-Day Price Jump Has Added Up Fast
Regular gasoline in Toronto was listed at 178.9 cents per litre on October 1 by Canadians for Affordable Energy’s Gas Wizard. It moved to 185.9 cents on October 2, an increase of seven cents, before another six-cent increase brought the October 3 figure to 191.9 cents. That represents a 13-cent-per-litre change in roughly 48 hours. CityNews, using data from En-Pro, projected a slightly lower GTA average of 190.9 cents for Saturday but likewise expected an overnight increase of six cents.
The small difference between the two forecasts is worth noting because retail fuel prices are not identical at every station. Regional averages and forecasts can vary depending on the stations being tracked, inventory turnover and local competition. What is consistent is the direction: much of the GTA experienced another substantial overnight increase after already absorbing a major move the previous day. For motorists who watched prices fall below 180 cents earlier in the week, the return toward the 190-cent mark has happened unusually quickly.
Wholesale Rack Prices Are Driving the Latest Increase
The most important clue behind Saturday’s increase is found farther up the gasoline supply chain. Gas Wizard specifically attributed the October 3 Toronto increase to a roughly six-cent surge in terminal rack pricing. Its October 2 outlook had already pointed to rising wholesale rack prices, higher gasoline futures and refinery turnarounds. In practical terms, stations are paying more for replacement fuel before that gasoline ever reaches the underground tanks beneath a retail forecourt.
Ontario’s explanation of gasoline pricing shows why that matters. Producers and importers sell gasoline to retail stations at wholesale prices that incorporate crude-oil and refining costs along with supplier margins. Retailers then add their own operating margin and applicable taxes. A sufficiently large movement in the wholesale component can therefore push pump prices higher even if nothing dramatic has changed at the individual station. For a driver passing the same station every morning, the sign may seem to change suddenly overnight, but the pressure often began earlier in wholesale markets.
Toronto Gasoline Is Closely Linked to New York Harbor
Ontario’s fuel-pricing data provides another important piece of context: Toronto’s wholesale gasoline market does not operate in isolation. The province says wholesale gasoline prices in Ontario are strongly influenced by major North American benchmark markets. For Toronto, one of the most important benchmarks is New York Harbor, while Thunder Bay pricing is more closely connected with Edmonton. That helps explain why developments outside Ontario can appear relatively quickly in southern Ontario pump prices.
The connection matters during periods when gasoline itself becomes more expensive relative to crude oil. Toronto suppliers compete within a broader North American fuel market, meaning the replacement value of gasoline can rise when benchmark prices strengthen, refinery output tightens or traders anticipate reduced supply. Ontario publishes daily comparisons between Toronto wholesale gasoline and the prior day’s New York Harbor price for exactly this reason. A driver filling a compact car in Mississauga may be hundreds of kilometres from New York, but movements in that benchmark can still influence what the next shipment of gasoline costs locally.
Falling Crude Does Not Automatically Mean Cheaper Gas
One of the more confusing features of the current increase is that crude oil did not simply surge six cents’ worth overnight. On October 2, Brent crude settled at $102.25 a barrel, down six cents, while U.S. West Texas Intermediate fell $1.76 to $91.11. At roughly the same time, Toronto’s regular gasoline outlook was moving higher. The apparent contradiction highlights an important distinction between crude oil and the finished gasoline eventually purchased at a station.
Crude is only one component of the retail price. It still has to be refined into gasoline, transported through the distribution system and sold through wholesale terminals before reaching retailers. The price relationship between crude and finished gasoline can widen when refining capacity, inventories or regional supply become constrained. That means a decline in the headline oil price does not guarantee an immediate decrease at Ontario pumps. During periods of tight refined-product supply, gasoline can move in the opposite direction from crude for short stretches, particularly when replacement costs at wholesale terminals are increasing.
U.S. Gasoline Inventories Are Relatively Tight
Recent U.S. fuel-market data helps explain why wholesale gasoline prices may be sensitive to relatively small disruptions. For the week ending September 25, U.S. gasoline inventories fell by approximately 1.7 million barrels to 204.3 million barrels. That placed stocks about seven per cent below the five-year seasonal average. At the same time, refinery utilization nationally fell from 94 per cent the previous week to 92.5 per cent, according to U.S. Energy Information Administration data.
Those numbers do not mean a specific Ontario price increase can be attributed entirely to U.S. inventories. They do, however, describe a North American gasoline market with less comfortable supply conditions than would exist with unusually high inventories and maximum refinery production. That distinction matters because Toronto wholesale prices are influenced by U.S. benchmarks. When available gasoline inventories are relatively lean, an outage, maintenance period or jump in demand can have a larger impact on wholesale pricing. Ontario motorists can therefore feel changes originating well outside the province even when local gasoline remains physically available.
Refinery Turnarounds Can Magnify Short-Term Moves
Refinery maintenance is another factor identified in the current wholesale increase. Gas Wizard’s October 2 Toronto forecast specifically cited refinery turnarounds alongside rising gasoline futures. Turnarounds are planned maintenance periods in which portions of a refinery can be taken offline for inspections, repairs and equipment work. They are necessary for safe operation, but they temporarily reduce the amount of fuel that can be produced while work is underway.
Canada’s Competition Bureau also identifies refinery capacity and maintenance as important influences on gasoline prices. When refinery supply becomes tighter relative to demand, the rack price—the price charged at the refinery or terminal level—can rise. The effect can be amplified when several pressures occur simultaneously. A market dealing with lower gasoline inventories, seasonal maintenance and stronger benchmark prices has less spare flexibility than one sitting on abundant supplies. That helps explain why pump prices can sometimes rise by six or seven cents in one adjustment rather than creeping higher by fractions of a cent over several weeks.
Ontario Is Not Seeing One Identical Price Change
Describing the move as an Ontario-wide six-cent increase is useful shorthand, but actual regional changes are more complicated. Canadians for Affordable Energy projected regular gasoline at 191.9 cents per litre in Toronto, the GTA, Mississauga, Burlington and Niagara on October 3, generally reflecting a six-cent increase. London, however, was projected at the same 191.9-cent level after a much larger 13-cent increase because its previous day’s benchmark was lower.
Northern Ontario presents another example. Thunder Bay was forecast at 202.9 cents per litre for October 3, three cents higher than the previous day, after experiencing a 10-cent increase on October 2. Ontario’s own market methodology helps explain why regional patterns can diverge: Toronto is more closely connected to New York Harbor wholesale pricing, while Thunder Bay is influenced by Edmonton. Transportation costs, local competition and inventory conditions can add further differences between communities. The province can therefore move in the same broad direction without every city changing by the same amount at midnight.
The Extra Cost Becomes Noticeable With Every Fill-Up
A few cents per litre can sound minor until the increase is multiplied across an entire tank. Using Toronto’s movement from 178.9 cents on October 1 to 191.9 cents on October 3, the difference is 13 cents per litre. Filling 40 litres at the higher price costs about $5.20 more than it would have at the October 1 level. A 50-litre fill costs an additional $6.50, while 60 litres adds approximately $7.80.
The impact becomes more noticeable for households that drive frequently or operate larger vehicles. Two 50-litre fill-ups would represent roughly $13 in additional fuel spending compared with the October 1 price, assuming the same volume is purchased. A small business consuming 500 litres of gasoline over a given period would face roughly $65 more in fuel expense at a 13-cent increase. Those calculations do not predict how long prices will remain elevated, but they illustrate why rapid overnight changes matter to commuters, tradespeople, delivery operators and families even when each individual increase is measured in pennies.
Toronto Is Now Above Its Recent Price Averages
The latest Toronto price is also high relative to the city’s recent benchmarks. Gas Wizard’s price-history data listed a 30-day average of 184.1 cents per litre and a 90-day average of 176.6 cents. Its year-to-date average stood at 165.1 cents. At 191.9 cents, the October 3 figure is therefore nearly eight cents above the recent 30-day average and more than 15 cents above the 90-day average.
The longer comparison is even more striking. Gas Wizard listed Toronto gasoline at 133.9 cents per litre one year earlier, although gasoline markets in 2026 have been shaped by very different energy conditions. Historical comparisons should therefore be treated as context rather than evidence that prices must return to a particular level. Still, the figures show why the latest move feels significant. It is not merely reversing a one-day discount. Saturday’s Toronto benchmark sits materially above the averages motorists have experienced over the past several months and follows a particularly abrupt two-day climb.
The Weekend Outlook Remains Sensitive to Wholesale Markets
For the immediate outlook, Gas Wizard’s October 3 Toronto forecast described the higher regular gasoline price as firm through Sunday. That suggests the wholesale increase that pushed Saturday’s price higher was not expected to disappear immediately. At the same time, fuel-price forecasts can change quickly. CityNews notes that current market fluctuations have been sporadic enough that its projected GTA price should be treated as an interim prediction that may be revised during the day.
That combination leaves Ontario motorists in a volatile pricing environment rather than one with a clearly established downward trend. Wholesale rack prices, New York Harbor gasoline benchmarks, refinery operations and North American inventory conditions remain more useful short-term indicators than crude oil alone. Local stations can also deviate from regional averages because of competition and inventory timing. Saturday’s six-cent GTA increase is therefore best viewed as another step in a fast-moving wholesale adjustment—one that has taken Toronto-area gasoline from below 180 cents to around 191 cents per litre in just two days.
