Oshawa anchors the east end of the GTA fuel market, and it is usually the cheapest corner of Durham Region. The south end’s working corridors — Simcoe Street South, King Street East, Bloor Street — carry a healthy share of discount independents that price below the majors, while the newer retail strips along Taunton Road and Harmony Road in the north end track a touch higher. The 401 interchange stations price for highway traffic and are rarely the local low.
Durham drivers have four adjacent markets to play — Oshawa, Whitby, Ajax and Pickering blur together along Highway 2 — and the cheapest pump in the region rotates between them. The list below ranks every Oshawa station we track by current price, refreshed hourly; the Whitby and Ajax pages are one click away for the cross-border comparison.
