Frequently asked questions
Are Costco gas prices going up or down in Canada right now?
It depends on the week and the province. This page recaps the recent direction in cents per litre for regular, premium, and diesel as a national average, then ranks the provinces and individual gas bars that moved the most. The snapshot box up top names the biggest mover right now.
How often do Costco gas bar prices change?
Costco changes pump prices often — sometimes more than once a week. We refresh this page daily from a rolling 30-day history, so it reflects the recent trend rather than one day’s price.
Where is Costco gas cheapest in Canada right now?
Prices swing a lot by province because of provincial taxes and the carbon levy — Alberta and the Prairies tend to be cheapest, while B.C. and Atlantic Canada run highest. Our Canada page ranks every province by its current average.
Why did Costco gas prices change recently?
Costco buys finished fuel from the same regional suppliers as other retailers, so its prices track the wholesale market — crude-oil moves, refinery issues, seasonal blends, provincial taxes, and the carbon levy all feed through, usually passed on quickly at a below-market margin.
How do you measure the “biggest movers”?
For each gas bar we compare the latest price against roughly a month earlier, using the same 30-day history behind our charts, then rank provinces and stations by that change. Stations without a comparable earlier reading are excluded, and moves under about 1.5¢/L are treated as flat.
Costco gas price trends in other countries
Prices move differently in each market. See the latest recap for the U.S., the UK, Australia, and Mexico.
How we measure this: for every Costco gas station we compare the latest price against roughly a month earlier, using the same 30-day history behind our price charts.
