Across the line

Diesel crosses the border, but the number does not. The Canadian side is published per litre and the American side per gallon.

Calgary · Canadian side237.2¢/L

Rocky Mountain · the US district next door$6.407/gal

The American figure is the EIA weekly retail survey — published as $6.407/gal this week — shown the way an American carrier reads it, with the Canadian-dollar equivalent beside it once the page loads. A gallon is not a litre, so these two lines measure the same fuel in different units and the cents will never match. What does compare is the market: a load crossing into Rocky Mountain buys its fuel on the other side of a border.

Calgary runs 23.7¢ below the national index — a real difference on a 500-litre fill. Work out a trip

How it is calculated

What drives Calgary prices

Calgary sits where Highway 1 and Highway 2 (the QEII) meet, a highway hub that moves a lot of freight. It is an oil patch service centre and home to corporate energy head offices, so trucks are always rolling through. On diesel, Calgary is usually the cheapest large fill in Alberta. Its position close to the Edmonton area refineries is a big part of why it runs cheap. For a carrier working the southern corridor, Calgary is the fill that makes the numbers work.
