Toronto Hydro is testing a new approach to accelerate the rollout of public EV fast chargers across Canada’s largest city, and it could significantly reduce both the cost and complexity of new installations.
The utility has launched an Electric Vehicle Fast Charging Pilot Program that gives charging providers direct access to 480-volt transformer service—something that’s typically not available through standard grid connections. By doing so, Toronto Hydro is removing one of the more cumbersome steps in building DC fast charging infrastructure.
Today, most DC fast chargers are designed to operate at 480 volts, but utilities, including Toronto Hydro, commonly distribute power at 600 volts. That mismatch has forced developers to install their own step-down transformers to convert the voltage, adding extra equipment, cost, and time to projects.
The new pilot eliminates that requirement entirely by delivering the correct voltage straight from the grid.
For companies looking to build out charging networks, that change could have a meaningful impact. Removing the need for a customer-owned transformer simplifies project design, reduces upfront capital costs, and cuts down on construction timelines.
It also frees up physical space at charging sites—an often overlooked constraint—allowing operators to install more stalls or add amenities.
The pilot is relatively small in scope, with space for up to 10 projects across Toronto. Each selected site will receive access to a utility-owned 480-volt transformer rated at up to 1.5 MVA, providing the exact power needed for DC fast charging equipment without additional conversion.
While participants will still cover installation and connection costs, Toronto Hydro will retain ownership of the transformer and handle ongoing maintenance, something which has traditionally been the responsibility of the site operator, adding long-term operational complexity. By shifting that burden back to the utility, the pilot further lowers barriers for companies looking to expand charging infrastructure.
The program is expected to run through the end of 2027, during which time Toronto Hydro will evaluate performance, system impacts, and compatibility. Those insights could ultimately shape how utilities support EV charging growth in the years ahead.
If successful, the pilot could serve as a model for other jurisdictions looking to speed up charger installations without requiring major changes to existing grid infrastructure.
