Canada’s Thanksgiving weekend is approaching with fuel prices sitting at levels that can turn an ordinary family road trip into a noticeably more expensive outing. On October 5, Global News reported a CAA national average of about $1.78 per litre for regular gasoline, while diesel was hovering near $2.55 per litre according to Canadians for Affordable Energy. Both are far above where drivers were a year earlier.
The diesel number is especially important because its impact stretches well beyond motorists who own diesel vehicles. Trucks, farms, construction equipment and delivery networks depend heavily on the fuel, giving a diesel spike the potential to work its way into prices throughout the economy. Meanwhile, a coordinated G7 reserve release may offer some relief, but energy analysts are warning that the market remains unusually difficult to predict.
The National Average Depends on Who Is Measuring It
The first thing drivers should know is that a Canadian “national average” is a snapshot, not a price that will appear on every pump. Global News reported on October 5 that CAA’s national average for regular gasoline was about $1.78 per litre. The same report put diesel near $2.55 per litre, based on an estimate from Canadians for Affordable Energy. Those figures capture the broad direction of the market, but another major daily survey produced a somewhat different gasoline number.
Kalibrate Canada’s Daily Pump Price Survey put its volume-weighted Canadian average on October 5 at 187.1 cents per litre for regular gasoline and 256.0 cents for automotive diesel. In other words, the two sources were quite close on diesel but farther apart on gasoline. Different data providers use different station samples, weighting methods and update times, while retail prices can move quickly. The safest interpretation is therefore not that every Canadian is paying exactly $1.78, but that gasoline is expensive nationally and diesel is dramatically more expensive still.
A Thanksgiving Fill-Up Costs Noticeably More
Thanksgiving Day falls on Monday, October 12, in 2026, making the coming weekend a natural period for family visits and highway travel. At a gasoline price of $1.78 per litre, a 50-litre fill costs about $89. A year earlier, when the national average cited by CAA was about $1.33 per litre, the same amount of fuel would have cost roughly $66.50. That is a difference of $22.50 before the trip has even started.
A longer drive makes the change equally easy to see. Consider a vehicle averaging 8.0 litres per 100 kilometres on a 600-kilometre round trip. It would consume about 48 litres. At $1.78 per litre, that fuel costs approximately $85.44; at $1.33, it would have been about $63.84. Real vehicles, traffic conditions and regional pump prices will produce different totals, but the example shows why this year’s fuel market is likely to be noticed around the household budget. A holiday meal may cost the same at the destination, while getting there can require an extra twenty dollars or more.
Diesel Is the Much Bigger Fuel Shock
Gasoline is painful for holiday drivers, but diesel is the more unusual part of the current fuel shock. Kalibrate’s October 5 national survey put automotive diesel at 256.0 cents per litre, 68.9 cents above its 187.1-cent regular-gasoline average. Global News separately reported diesel hovering around $2.55 per litre and cited energy analyst Dan McTeague as saying diesel prices had nearly doubled from a year earlier. That widening gap matters because diesel is deeply embedded in commercial transportation and production.
Scotiabank Economics has tried to measure what happens when diesel rises by more than crude oil alone would normally explain. Its October 5 analysis estimated that a temporary diesel-specific shock of about 15% could add roughly 0.6 percentage points to Canadian year-over-year CPI inflation. That is a modelled effect, not a prediction that inflation will automatically rise by exactly that amount. The study nevertheless found statistically significant spillovers beyond energy, showing why diesel prices can become an economy-wide issue even for households that never put a litre of diesel into their own vehicles.
The Problem Is No Longer Just the Price of Crude Oil
The latest fuel squeeze is not simply a story of the world running out of crude oil. Reuters reported that crude flows through the Strait of Hormuz had recovered to about 14.2 million barrels per day on a seven-day average in late September, close to 80% of pre-war levels. Yet Brent crude remained above US$100 a barrel. The problem has increasingly shifted toward moving, insuring and refining oil rather than merely getting it out of the ground.
Shipping costs illustrate how distorted the system has become. Reuters reported that rates for very large crude carriers moving oil from the Middle East to Asia had recently exceeded US$1.2 million per day, compared with roughly US$30,000 in January. Freight that once represented about 3% of a delivered barrel’s cost had climbed to roughly 27% on those routes. At the same time, lost refining capacity in the Middle East and damage to Russian refineries have tightened diesel supply. Crude can be available and still fail to translate quickly into abundant diesel if there are not enough efficient routes and functioning refineries to turn it into fuel and deliver it.
The G7 Is Releasing Reserves, but Relief Is Not Guaranteed
Governments are trying to relieve that pressure. On October 2, G7 leaders agreed to a coordinated release through the International Energy Agency of 100 million barrels over four months. The plan calls for a substantial diesel release within the first 20 days, with G7 members and partners front-loading some of the supply. Leaders also committed to avoiding energy export restrictions among G7 countries and said additional diesel releases could be considered if necessary.
That is significant, but it is not the same as guaranteeing a specific drop at Canadian pumps. Emergency stocks can put more fuel into the market and calm expectations, yet they do not rebuild damaged refineries, lower tanker insurance costs or permanently restore disrupted trade routes. Canadian energy analysts have said prices remain exceptionally difficult to forecast more than several days ahead. Reuters has similarly noted that strategic diesel releases may provide only temporary relief while refining constraints remain. For Thanksgiving travellers, the practical message is that short-term improvement is possible, but there is no firm basis for assuming a large holiday-weekend price drop.
Where the Tank Is Filled Can Change the Bill Dramatically
The national average also hides an enormous regional spread. Kalibrate’s October 5 survey listed regular gasoline at 145.6 cents per litre in Edmonton and 214.0 cents in Vancouver. In St. John’s, the reading was 224.4 cents. Diesel showed a different but still expensive pattern: 225.4 cents in Edmonton, 272.9 cents in Vancouver and 273.3 cents in St. John’s. A Canadian road trip can therefore encounter very different fuel costs depending on where the tank is filled.
The difference between Edmonton and St. John’s regular gasoline in that survey was 78.8 cents per litre. On a 50-litre purchase, that gap works out to $39.40. CAA notes that pump prices vary with factors including regional taxes, competition, station location and sales volumes, while broader fuel prices also reflect crude costs and refining conditions. Geography therefore matters almost as much as the national headline. A driver in Alberta may read about $1.78 gasoline and see a local price well below it; another in Atlantic Canada or British Columbia can face something substantially higher. National averages are useful for direction, but poor substitutes for local trip budgeting.
Diesel Prices Can Eventually Show Up in Grocery and Delivery Bills
Diesel’s importance becomes clearer once the pump is connected to the supply chain. Statistics Canada reported that prices for truck transportation rose 9.5% year over year in the second quarter of 2026 and 5.3% from the previous quarter. It also found that producer diesel prices in July were 40.3% to 58.8% higher than a year earlier, depending on the region. In the third quarter, 22.4% of transportation and warehousing businesses expected to raise their prices in the next three months.
Scotiabank’s modelling suggests that the impact can arrive with a considerable lag. It found transportation prices responding first, while the estimated effects on shelter and food build later, with food effects peaking around 18 months after a diesel shock in its model. Canada Post offers a real-world example of how diesel enters consumer-facing charges: its domestic parcel fuel surcharge is tied to average Canadian diesel prices and adjusted weekly. On October 5, Canada Post announced a temporary 15% discount on the published fuel surcharge for eligible domestic parcels through January 3, 2027, explicitly aiming to help customers manage shipping costs.
Canada’s Temporary Federal Fuel-Tax Break Has Already Ended
One piece of the current price backdrop is domestic tax policy. Ottawa temporarily suspended the federal fuel excise tax from April 20 through September 7, setting the federal rate at zero during that period. On September 8, the full rates returned: 10 cents per litre on gasoline and 4 cents per litre on diesel. The reinstatement cannot explain the full surge in pump prices, especially with global crude, refining and transportation costs under severe pressure, but it removed a temporary cushion Canadian motorists had received through the spring and summer.
What happens by Thanksgiving remains uncertain. Global News reported West Texas Intermediate crude around US$90 per barrel on October 5, below a recent September peak but still caught in a volatile market. Analysts cautioned that geopolitical developments can reverse price movements quickly, while the G7 reserve release has not solved the underlying refining and logistics problems. For motorists, the national average should therefore be treated as a budgeting reference rather than a promise. Checking local prices before leaving, allowing room for regional differences and avoiding assumptions about a last-minute holiday drop are more realistic responses to a market capable of moving sharply within days.
