Bill 52: EV-Ready Homes Act (Electric Vehicle Charging), 2025

This bill directly affects residential home builders and construction contractors in Ontario who build single-family or Part 9 houses (typically houses up to 600 square metres). On a day-to-day basis, it changes how they plan and execute the electrical rough-in for new homes — they'll need to install a 200 amp panel, a 27 mm conduit run to the garage or driveway area, and a 4-11/16 inch outlet box as standard practice. Electrical subcontractors working on new residential builds will also be impacted, as they'll need to incorporate EV-ready wiring into every qualifying home. Both small custom home builders and larger volume builders/developers will be affected equally, though larger developers may feel the cumulative material and labour cost increase more acutely across subdivisions.
