Brockville is a compact 401 town midway between Kingston and Cornwall, and its fuel market follows the highway: the Stewart Boulevard corridor running from the 401 down to the river carries most of the stations, with Parkedale Avenue’s retail strip and the King Street downtown pumps filling out the list. Like its corridor neighbours, the stations closest to the interchange price for through-traffic.
For Toronto–Montreal drivers, Brockville is a legitimate alternative to stopping in Kingston — the two markets move independently, and the smaller town takes the low often enough to be worth the check. The list below ranks every Brockville station we track by current price, refreshed hourly.
