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.

Ottawa · Canadian side262.9¢/L

Central Atlantic · the US district next door$6.496/gal

The American figure is the EIA weekly retail survey — published as $6.496/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 Central Atlantic buys its fuel on the other side of a border.

Ottawa runs 1.4¢ below the national index — a real difference on a 500-litre fill. Work out a trip

How it is calculated

What drives Ottawa prices

Ottawa is the national capital on the Highway 417 and Highway 416 network, and its economy runs on government and tech. The city sits close to the Quebec border, so its pricing competes with Gatineau across the river. Government and tech keep the freight mix steady, with trucks serving an economy built on offices rather than heavy industry. That cross-border competition with Gatineau is the defining pressure on Ottawa's fuel prices, and it keeps the two sides of the river closely matched.
