About Costco Gas in Canada

Costco is one of Canada's largest fuel retailers, operating gas stations at select warehouse locations across British Columbia, Alberta, Ontario, and Saskatchewan. Costco gas prices are typically 5–15 cents per litre lower than major competitors, thanks to Costco's high-volume, low-margin business model that uses fuel as a membership benefit rather than a primary profit center.

YepSavings tracks Costco gas prices at 6 Canadian locations, with snapshots updated every Monday and Friday. Our price data covers Regular (87 octane), Premium (91 octane), and Diesel where available. While actual pump prices may change between our update windows, our historical data and trend tracking help you plan the best time to refuel.

Beyond gas prices, YepSavings also tracks Costco in-store unadvertised deals, flyer promotions, new arrivals, and product recalls across Canada — helping members get the most out of every trip to Costco.
