Fuel costs in Canada have moved in ways that make budgeting genuinely difficult this year. National diesel averaged C$1.54 in January and climbed to a peak of C$2.33, a jump of 51 percent. Regular gasoline followed a similar arc, rising from C$1.33 to a peak of C$1.92, up 45 percent. For a fleet manager running route-level economics on spreadsheets built months ago, those swings don't just erode margin. They break the math entirely. This post looks at what happened at the national level, how Ontario and British Columbia diverged from each other, and what a fleet operator should actually do about it heading into the next planning cycle.
The National Picture: A Year of Two Very Different Fuels
Diesel and gasoline haven't moved together this year, and that matters for mixed fleets running both light-duty and heavy trucks. Diesel climbed from C$1.54 in January to a peak of C$2.33 and has stayed there, with the latest reading matching the peak. There's been no meaningful pullback. Gasoline tells a slightly different story: it also spiked, hitting C$1.92, but has since eased back to C$1.76. That's still well above January levels, but the retreat gives light-duty fleets a bit more breathing room than their diesel-dependent counterparts get.
For a mixed fleet, this divergence is the real planning problem. A dispatch team optimizing for gasoline vehicle routes might be tempted to read the recent pullback as a sign that costs are normalizing. Diesel says otherwise. Long-haul and heavy equipment operations are paying near-peak prices with no relief in sight, and any budget built on the assumption that diesel would follow gasoline's downward drift is already out of date.
Ontario: Canada's Busiest Freight Corridor Under Pressure
Ontario carries a disproportionate share of Canadian freight volume, and its fuel trajectory reflects that exposure. Diesel in the province ran from C$1.43 in January to a peak of C$2.26, a rise of 58 percent, and the latest figure sits just below that peak. Gasoline moved from C$1.26 to C$1.88 at its high, a 49 percent increase, before settling to C$1.72 most recently.
What stands out about Ontario is how close the current diesel price sits to its high point. There's essentially no cushion. Fleet managers running the 401 corridor, cross-border lanes into the U.S. Midwest, or last-mile networks across the Greater Toronto Area are operating at cost levels that look like a worst-case scenario on paper but are, in fact, just the current baseline. Route profitability models built around the January numbers are off by more than half on the diesel side. Anyone still quoting customers or internal stakeholders using older fuel assumptions needs to revisit those numbers immediately, not at the next quarterly review.
The gasoline side offers modestly more room to maneuver. The retreat from C$1.88 to C$1.72 is meaningful for delivery vans, service vehicles, and light-duty fleets, though it's worth remembering that C$1.72 is still 37 percent above the January starting point. Relief, yes. Normalization, no.
British Columbia: The Steepest Climb in the Country
British Columbia posted the highest prices of the two provinces examined here. Diesel rose from C$1.63 in January to a spring peak of C$2.53, a 56 percent increase, and at C$2.44 its latest reading is the highest current figure available. Gasoline climbed from C$1.50 to C$2.18, up 45 percent, before easing to C$1.86.
BC's geography and fuel supply structure have long made it more exposed to price shocks than most of the country, and this year's numbers bear that out. A diesel price of C$2.44 changes the calculus for any fleet running through the Lower Mainland, the Interior, or up into the northern resource corridors. Operators serving construction, forestry, or resource extraction clients in BC are absorbing costs that are structurally higher than what an Ontario-based fleet manager might be budgeting for on comparable routes.
The gap between BC's diesel peak (C$2.53) and its current reading (C$2.44) is small: little retracement on the diesel side. Gasoline again shows more give, dropping to C$1.86 from its C$2.18 high, but that's still a sizable premium over where the year began. For BC fleet managers, the practical takeaway is that diesel exposure needs to be treated as a fixed, elevated cost of doing business right now, not a temporary spike waiting to correct.

What's Actually Driving This
A few forces sit behind these numbers, and understanding them helps fleet managers separate noise from signal. Energy market coverage this quarter has flagged sustained pressure on diesel pricing tied to crude cost movements and refinery output, a theme that's shown up consistently in industry roundups covering names like Keyera alongside broader crude trends. Diesel's tighter refining margins compared to gasoline help explain why it has held near its peak while gasoline has pulled back.
Macro conditions add another layer. Stronger than expected jobs data recently pushed bond yields higher and revived expectations that interest rates could stay elevated for longer. Higher rates raise the cost of financing new trucks, trailers, and equipment, which compounds fuel pressure rather than offsetting it. At the same time, the Canadian dollar's relationship to the U.S. dollar matters more than most fleet managers give it credit for. A softer greenback (the WSJ Dollar Index recently slipped before a modest rebound) can ease the cost of imported parts and vehicles, but fuel pricing in Canada doesn't track the exchange rate cleanly enough to offer real relief on its own.
On the vehicle side, auto and transport sector news involving manufacturers like Volkswagen and BRP points to continued supply adjustments in the vehicle and equipment market. For fleets planning replacement cycles, that's a reminder that total cost of ownership calculations need to account for both fuel volatility and shifting vehicle costs at the same time, not as separate line items reviewed in isolation.
What This Means for Fleet Budgets
The practical problem for fleet managers isn't just that prices are high. It's that they're high and unpredictable in different directions depending on fuel type and province. A national average masks the fact that a BC-heavy diesel fleet is facing a materially different cost environment than an Ontario-heavy gasoline fleet. Budgets built on national averages will misprice both.
Contract renewals with shipping customers are especially vulnerable right now. If a rate was negotiated based on January fuel costs, that agreement is likely underwater on diesel-heavy lanes. Renegotiating fuel surcharge clauses, or at minimum indexing them to more current, region-specific figures, should be a near-term priority for any fleet manager with contracts up for renewal in the next few months.
A Practical Response for Fleet Managers
This is exactly the kind of volatility that a fixed-price fuel supply agreement is built to address. FuelAnchor works by locking in a maximum price per gallon for a defined volume of fuel, so a fleet that's watched diesel climb from C$1.54 to C$2.33 nationally can plan its per-mile costs with a hard ceiling instead of hoping prices retreat. It doesn't eliminate the cost of fuel, but it removes the guesswork from budgeting, which matters more than ever when diesel and gasoline are moving in different directions across provinces.
Beyond a price ceiling arrangement, a few tactical moves help right now. Route optimization software that accounts for real-time provincial price differences, rather than a single national figure, will produce more accurate per-job costing. Renegotiating customer contracts to include fuel cost clauses tied to current regional data, not stale averages, protects margin on longer commitments. And building replacement vehicle decisions around total cost of ownership, factoring in both fuel type exposure and financing costs given where rates currently sit, will matter more over the next planning cycle than it has in recent years.
Pull your fleet's fuel spend by province for the last two quarters and compare it against these figures. If diesel costs in Ontario or BC are running close to the peaks cited here, that's the number to bring into your next rate conversation, not the number from January.
