Esso (Imperial Oil) has one of the biggest brand footprints we track in Winnipeg, and it has grown in recent years for a distinctly prairie reason: when Cenovus wound down the Husky retail brand, many of Winnipeg’s old Husky corners re-signed as Esso. Add the 7-Eleven and independent corner stores that pump Esso-branded fuel — the store sign and the fuel brand are often different companies — and Esso is the major you are statistically most likely to be nearest to.
Esso’s loyalty hook is PC Optimum — Esso and Mobil are the program’s fuel partners — so every litre earns points redeemable on groceries at Real Canadian Superstore, No Frills and the other Loblaw banners. For a household that already shops there, base earn plus the frequent app multipliers works out to roughly 1–2¢/L back in grocery credit on top of the posted price.
The ranked list below refreshes hourly. As with every major in Winnipeg, the cheapest Essos cluster where the competition is: the Regent, McPhillips and Pembina corridors, where co-op and warehouse-club pricing keeps everyone honest.
