Please note that this map is purely for information purposes; you must work with Hydro One directly to schedule your connection and have it installed.

Read the map legend

The map legend helps you interpret the colour-coded representation of our distribution system’s capacity. The colour-coded areas, which may extend upwards 1 km from the associated distribution feeder, illustrate the load capacity at the feeder level and consider constraints from the applicable upstream distribution station.
