Fuel costs in Canada have swung wildly this year, and the swings look different depending on where your trucks actually fill up. A national average is useful for headlines, but it hides the fact that Ontario and British Columbia have been moving on almost separate tracks. If you're managing a fleet with routes across provincial lines, that gap matters more than the topline number ever will.
Why Provincial Numbers Matter More Than the National Average
Canada's national diesel price started the year around C$1.54 per litre and climbed to C$2.45, its highest reading of the year and still the latest. That's a jump of roughly 59% from January, and prices haven't retreated. Gasoline followed a similar arc, up from a C$1.33 January average to a C$1.92 peak, a 45% increase, before easing back to C$1.80.
Those national figures are a reasonable starting point for a budget conversation with your finance team. But provincial markets don't move in lockstep, and the spread between them can be the difference between a route staying profitable and one that quietly bleeds margin. Ontario and BC illustrate that gap clearly, and both are worth a closer look if you're running mixed fleets or cross-border freight.
Ontario: A Volatile Middle Ground
Ontario's diesel market started the year below the national figure, at C$1.43 in January, and rose to C$2.37, its highest reading of the year and the most recent. That's a 65% increase from the January baseline, a larger jump than the national number but still enough to blow through most quarterly fuel budgets set back in the winter.
Gasoline in Ontario tells a similar story. January averaged C$1.26, the peak hit C$1.88, and the latest reading sits at C$1.79, a 43% rise from where the year began. For fleets running last-mile delivery or regional distribution in the Greater Toronto Area and southern Ontario corridors, this is the price environment you've likely felt most directly, since gasoline-powered vans and light trucks make up a large share of urban fleets.
What makes Ontario tricky for planning is the pace of movement rather than the size of it. Prices didn't climb in one straight line. They moved in bursts tied to global supply news, then held at elevated levels for weeks before adjusting again. That kind of stop-start pattern is hard to plan around with a static fuel line item, because whatever number you build into a quarterly forecast is likely to be wrong within a few weeks in either direction.
British Columbia: The Most Exposed Market in Canada
If Ontario has been volatile, British Columbia has been the most exposed provincial market in the country. Diesel opened the year at C$1.63, above the national average, and rose to C$2.57, the highest of any figure in this data set and its latest reading. That's a 58% increase from January, in line with the national number and below Ontario's, because BC started from a higher base. BC diesel hasn't pulled back at all: it is at its highest level of the year.
Gasoline in BC followed the same pattern of relative severity. January's C$1.50 average climbed to a C$2.18 peak, a 45% rise, before easing to C$1.87. That's broadly in line with the national gasoline trend, but paired with diesel prices that remain among the steepest in the country, BC fleets running mixed diesel and gasoline vehicles are absorbing a heavier combined load than fleets almost anywhere else in Canada.
For fleet managers based in or routing through BC, particularly those serving the Lower Mainland, Vancouver Island ferry-dependent routes, or long-haul corridors into the interior, this isn't a temporary spike to wait out. Diesel sitting at its highest level of the year signals a market that hasn't found its floor yet, and budgeting on the assumption that prices will simply revert to January levels looks increasingly unrealistic.

What's Driving the Volatility Right Now
None of this is happening in a vacuum. Iran and Oman are working through provisional safe passage arrangements for commercial shipping through the Strait of Hormuz, a route that a large share of the world's oil transits daily. Saudi Arabia has responded to regional tension by shutting a major pipeline after drone activity linked to the conflict, pushing more of its output through alternative routes and adding friction to global supply.
There's also a political dimension shaping expectations. Recent public comments from US officials have suggested that oil prices could fall sharply if the Iran conflict resolves in the coming months, and markets did pull back on hopes of renewed negotiations even after a run of sharp weekly gains that pushed oil above US$100 a barrel. That kind of on-again, off-again optimism is exactly what's been whipsawing pump prices across Canada. A single diplomatic headline can move oil markets meaningfully before any actual barrel changes hands, and Canadian retail prices tend to catch up within days.
Domestically, Iran's own government is dealing with internal resistance to new security measures aimed at foreign infiltration concerns, a sign that the situation inside the country remains unsettled even as external negotiations continue. For fleet managers, the practical takeaway isn't the politics itself. It's that the underlying supply picture remains genuinely unresolved, and betting on a quick, durable price drop is a real risk to build into your operating plan.
Budgeting When the Range Is This Wide
When diesel can move from C$1.54 to over C$2.50 in a matter of months, static budgeting stops working. A few adjustments help.
First, stop anchoring quarterly forecasts to a single point estimate. Build a range using the January and peak figures for your specific province, not the national average, since Ontario and BC alone show how different those ranges can be.
Second, separate your gasoline and diesel exposure if your fleet runs both. The two haven't moved identically this year, and treating them as one combined "fuel cost" line can mask which vehicle class is actually driving the overage.
Third, revisit contract pricing with customers or internal cost recovery models more frequently than you have in the past. A pricing structure built around a C$1.54 diesel assumption doesn't hold up when the actual cost is C$2.37 in Ontario or C$2.57 in BC.
This is where a fixed-price fuel supply agreement earns its place in the conversation. FuelAnchor locks in a maximum price per litre for your fleet's fuel supply, so when the market spikes the way it has this year, your cost is capped even while pump prices around you keep climbing. It doesn't require predicting where oil prices go next. It just removes that variable from your budget entirely, which matters a lot more when provincial markets are moving as differently as Ontario and BC have been.
A Practical Next Step
Pull your fleet's actual fuel spend by province for the past two quarters and compare it against the January and peak figures above for wherever your trucks run. If the gap between your budgeted number and your actual cost is wider in BC than in Ontario, or the reverse, that's the first sign you need province-specific planning rather than a single national assumption. Start there before your next budget cycle locks in numbers that the market has already left behind.
