FAQs
Canada follows the Canadian Electrical Code (CEC), published by the Canadian Standards Association (CSA). This national standard outlines installation, grounding, and wiring requirements to ensure electrical safety across residential, commercial, and industrial systems.
Electrical installation involves several steps: obtaining permits, designing the circuit layout, routing and securing cables, connecting breakers and outlets, and performing safety tests. Licensed electricians must follow CEC, their respective province’s safety codes, and local building codes to meet inspection requirements.
Electrician rates in Canada typically range from CAD $150 – $300 per hour, depending on location, experience, and job complexity. Larger projects, such as commercial wiring or service upgrades, may be priced as fixed quotes rather than hourly rates.
Rewiring an average-sized Canadian home is astronomical, but the average 1600-2000 sq ft house would range between $15k and $35k, depending on the house’s size, accessibility, and the condition of the electrical panel. Older homes with outdated wiring systems, such as knob-and-tube, often require a complete rewiring to meet modern safety codes.
A commercial electrician specializes in wiring, maintenance, and repair of electrical systems in offices, retail spaces, factories, and public buildings. They handle higher voltage systems than residential electricians and ensure compliance with commercial building codes.
Yes, but it can be challenging. Most insurers in Ontario consider knob and tube wiring a higher fire risk, so coverage often requires an electrical inspection by a licensed electrician confirming it’s safe. Some companies may still insure the home but charge higher premiums or require you to upgrade the wiring within a set timeframe.
In Ontario, electrical inspections are performed by the Electrical Safety Authority (ESA). Homeowners or contractors must file a work notification before beginning an installation. Once the job is complete, an ESA inspector reviews the work to confirm code compliance.
A complete electrical inspection involves examining wiring, outlets, panels, grounding, and circuit protection to ensure safety and code compliance. A licensed electrical contractor also checks for overheating, faulty breakers, and improper connections that could cause hazards.
Copper wiring is considered the safest and most reliable for residential and commercial use. It has excellent conductivity, resists corrosion, and handles high electrical loads without overheating.
Most modern Canadian homes use non-metallic sheathed (NM) cable, commonly known as Romex, which contains copper conductors encased in a plastic sheath. Older homes may have aluminum wiring, which should be inspected and, if found to be unsafe, replaced for safety reasons.
