Ontario Electrical Code

When working with Ontario Electrical Code, the provincial set of rules that dictates how electrical systems must be installed and maintained in Ontario homes and businesses. Also known as O.E.C., it aligns with the broader Canadian Electrical Code, a national safety standard that each province adapts to its own needs, and it forms the backbone of safe wiring practices.

Understanding the code starts with electrical inspections, the official check that confirms a new or renovated system meets code requirements. A qualified licensed electrician, someone certified to interpret and apply the code in the field will review residential wiring layouts and ensure grounding, circuit sizing, and device placement are all up to spec. Skipping these steps can lead to overloads, fire hazards, or costly re‑work, so the code emphasizes clear labeling, proper conduit use, and regular maintenance.
