Kingston sits alone on the 401 between the Toronto and Ottawa markets, and its prices march to their own drummer — often a few cents above the big-city lows, since the nearest serious price pressure is an hour away in either direction. Competition concentrates in the west end around Gardiners Road and the RioCan/Cataraqui retail node, along Princess Street, and at the Division Street 401 interchange.
For highway travellers the west-end retail cluster is the practical detour: two minutes off the 401 and usually cheaper than the interchange pumps. The list below ranks every Kingston station we track by current price, refreshed hourly.
