Port Weller, Ontario is a community in St. Catharines, Regional Municipality of Niagara, Ontario, Canada and is part of the Golden Horseshoe region. It is located 8 kilometres (5.0 mi) north of the centre of St. Catharines at the north end of the Welland Canal at Lake Ontario, but part of that city in much the same way as Port Dalhousie. Port Weller is bounded by Lake Ontario (North Boundary), Read Road (East), Linwell Road (South) and Walkers Creek (West Boundary). Port Weller East & West are divided by the Welland Canal. Port Weller West has a significantly higher population than Port Weller East because of industrial and agricultural development on the east side, such as the Welland Canal, Port Weller Dry Docks and local farms.
