Leamington anchors the greenhouse belt at Ontario’s southern tip, and with Kingsville and Essex it forms a compact south-county market a half hour from Windsor’s price wars. The stations line Talbot Street (the old Highway 3) and Erie Street toward the Point Pelee road, with Kingsville and Essex each holding a small cluster of their own — and the whole county usually prices a cent or two above Windsor’s discount-driven floor.
That gap is the local lever: commuters into Windsor do well filling at the city end, where the Costco and the Tecumseh Road independents set the pace. For everyone staying in the county, the list below ranks every Leamington, Kingsville and Essex station we track by current price, refreshed hourly.
