How to read the result

  • GFCI protects people from shock where it can be wet. It is usually a GFCI receptacle, or a GFCI breaker for the whole circuit.
  • AFCI protects against fires from damaged wiring and loose connections, and is normally an AFCI breaker in the panel.
  • “Confirm locally” means the answer can depend on code edition or provincial amendments. Ask your inspector.

Results are a quick reference only. They summarize the common rules and do not replace the current Canadian Electrical Code, provincial amendments, or your local inspector. Adding or changing circuits needs a permit in Ontario.
