Peterborough is the fuel hub for the Kawarthas, and its market carries a cottage-country rhythm: prices firm up ahead of summer weekends as Highway 115 traffic pours through, then ease midweek. Competition concentrates along Lansdowne Street across the south end, Chemong Road’s big-box strip in the north, and the George Street and Water Street corridors through the middle.
For cottagers the rule mirrors Barrie’s: fill in town before heading up the county roads, where station density drops and prices rise with the distance from competition. The list below ranks every Peterborough station we track by current price, refreshed hourly — Thursday evening is typically the smart fill before a summer weekend.
