Waterloo’s stations line the corridors that stitch it to Kitchener — Weber Street, King Street, University Avenue and Northfield Drive — and its prices move with the wider tri-city market. Waterloo has fewer discount independents than its neighbours, so its floor tends to sit a touch above Kitchener’s on days when the cycle is drifting down.
The practical play for Waterloo drivers is to compare this page against the Kitchener list before filling: the boundary between the two cities runs through ordinary retail strips, and the cheapest pump in the pair is often a five-minute drive whichever side you start from. The list below ranks every Waterloo station we track, cheapest first, refreshed hourly.
