Petro-Canada (Suncor’s retail brand) runs a substantial network across Winnipeg, from city arterials to the highway plazas on the routes out of town — the Trans-Canada approaches and the Perimeter interchanges. Like every major, its posted price varies corner by corner with local competition: the same day can see a Regent Avenue Petro-Canada near the bottom of the city ranking and a neighbourhood site near the top, several cents apart — which is exactly what the live ranking below is for.
The brand’s differentiator is loyalty. Petro-Points is one of the more generous fuel programs when stacked with an RBC-linked card or CAA membership — the combinations return the equivalent of 1–3¢/L in practice. It also publishes the daily wholesale rack prices we use for the fill-up-or-wait predictor, a small transparency point in the brand’s favour. The list below ranks every Petro-Canada we track by its current price, refreshed hourly.
