Diesel Spread Hits 23.6 Cents. What That Costs on a Real Run
The numbers
Canadian diesel averages 171.9 cents a litre. But the spread is 23.6. That is the gap between Alberta at 158.9 and Newfoundland at 182.5. Same fuel. Same specification. A 23.6 cent spread from one end of the country to the other.
Seven provinces sit below the national average. Alberta leads at 158.9. Saskatchewan follows at 162.3. Manitoba at 165.7. Ontario at 171.2, just under the line.
Three provinces break above 175. Quebec at 175.8. PEI at 176.1. British Columbia at 178.5. Newfoundland rounds out the top at 182.5, a full 10.6 cents above the national number.
What it costs on a real run
Take Calgary to Vancouver. 970 kilometres. At 35 litres per 100 kilometres, that is about 340 litres of diesel.
Fill in Alberta at 158.9 and the total is $540. Fill in BC at 178.5 and the total is $607. The difference is $67 on one tank.
Two fills a week. That is $7,000 a year. A five truck fleet burns an extra $35,000 annually on the same route. The distance does not change. The cargo does not change. What changes is where the tank gets filled.
Edmonton to Vancouver tells the same story with bigger numbers. 1,160 kilometres. 406 litres. $645 in Alberta and $725 in BC. That is $80 on a single fill.
It is mostly tax
Every province pulls from the same wholesale market at roughly the same base price.
The gap is tax. Alberta adds 23 cents in combined carbon levy, fuel tax, and sales tax. British Columbia adds 42 cents. A 19 cent difference before a litre of fuel leaves the rack. Saskatchewan and Manitoba fall in between at 30 and 32 cents respectively. The further east you go, the heavier the tax load gets.
The cross-border comparison
The Canadian dollar strengthened to 1.3977 per US dollar. Washington state diesel converts to roughly 140 cents CAD. Fill in Blaine instead of Surrey and the math gets hard to ignore.
What to do about it
Planning fuel stops around the spread is not deadheading. It is routing.
For carriers doing regular cross province runs, a fuel card with network coverage in low tax provinces pays for itself in weeks. For owner operators running irregular routes, knowing the spread is the cheapest insurance against burning a few thousand dollars a year on tax differences alone.
National diesel sits at 171.9. Where you fill is the only part of that number you control.
