Canadian building code question

What are the building code requirements for electric vehicle ready buildings in Canada?

EV-ready building requirements are emerging across Canadian jurisdictions through building code amendments, municipal bylaws, and provincial legislation. Requirements typically mandate electrical capacity, conduit roughing-in, or full EV charging stations for a percentage of parking spaces in new buildings.

Electric vehicle readiness is a rapidly evolving area of Canadian building regulation. While the NBC 2020 included initial EV charging provisions, provincial codes and municipal bylaws are moving faster with specific requirements for electrical panel capacity, conduit rough-in to parking spaces, and installed charging stations. The requirements vary significantly by jurisdiction and building type, making it essential to check the current local provisions rather than relying on the national baseline alone.

What to check first

  • EV-ready requirements vary widely by jurisdiction and are evolving rapidly.
  • Requirements typically cover electrical capacity, conduit rough-in, and a percentage of spaces with installed chargers.
  • New multi-unit residential and commercial buildings are the primary targets of current EV-ready provisions.

Jurisdiction notes

National baseline

The NBC includes EV charging provisions, but many jurisdictions have moved ahead with more specific requirements.

Provincial codes

BC, Ontario, and Quebec have adopted or are developing EV-ready requirements that exceed the NBC baseline.

Municipal bylaws

Cities including Vancouver, Toronto, and Montreal have specific EV-ready bylaws with higher requirements than provincial codes.

Work through it in this order

  1. Check your municipality's EV-ready bylaw and the provincial building code for applicable requirements.
  2. Determine the required number of EV-ready, EV-capable, and EV-installed parking spaces.
  3. Size electrical service and panel capacity to support current requirements and future EV demand.
  4. Plan conduit routing and electrical room space for EV charging infrastructure.

Common questions

Do all new buildings need EV charging?

Requirements vary by jurisdiction and building type. New multi-unit residential buildings in major cities typically have EV-ready requirements.

What is the difference between EV-ready and EV-capable?

EV-ready typically means a parking space with conduit and electrical capacity for a charger. EV-capable means full conduit and wiring installed but no charger.

How do I size the electrical service for EV charging?

Sizing depends on the number of EV-ready spaces, the charger type, and load management strategies. Consult the applicable code and an electrical engineer.
