Bill 52 explained in plain English

Bill 52 amends the Building Code Act, 1992 to require new houses with garages, carports, or driveways to be built with electrical infrastructure (a 200-amp panel, conduit, and outlet box) that will allow future installation of electric vehicle charging equipment.

Bill 52, called the EV-Ready Homes Act (Electric Vehicle Charging), 2025, is a private member's bill that adds new requirements to Ontario's Building Code Act. The bill requires that new residential homes built after the law comes into force must be "EV-ready"—meaning they must have the electrical infrastructure in place to support future electric vehicle charging, even if the charging equipment is not installed right away. The requirement applies to homes that: (1) are built under Part 9 of the building code (which covers residential buildings); (2) have a garage, carport, or driveway; (3) are connected to an electrical distribution system; and (4) are not seasonal recreational buildings. For these homes, builders must install three specific components during construction: - A minimum 200-amp electrical panel board - A conduit (pipe) that is at least 27 mm in trade size, equipped with a way to pull cables through it - A square electrical outlet box (4-11/16 inch trade size) located in the garage, carport, or adjacent to the driveway These components must also block gas and exhaust fumes from passing through them. The components are designed to meet the standards for electric vehicle supply equipment under Ontario's Electrical Safety Code. The bill does not require builders to install actual charging equipment—only the infrastructure that would allow a homeowner to add a charger later. The law will come into force on a date to be set by order of the Lieutenant Governor in Council.
