Ajax packs its stations into a compact grid — Harwood Avenue and Westney Road running north–south, Kingston Road (Highway 2) and Bayly Street east–west — so nothing in town is more than a few minutes from anything else. That density keeps prices competitive: Ajax usually tracks within a cent or two of Oshawa’s Durham-leading lows, and its Highway 2 stations trade undercuts with Pickering’s next door.
The 401 interchange pumps at Salem and Westney price for highway traffic; the same brands a kilometre north or south on the local grid are routinely cheaper. The list below ranks every Ajax station we track by current price, refreshed hourly — with Pickering and Whitby one click away for the neighbour check.
