Frequently Asked Questions

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 Older homes with outdated wiring systems, such as knob-and-tube, often require a complete rewiring to meet modern safety codes.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.

Yes. Electricians remain in demand across Canada due to ongoing residential construction, infrastructure upgrades, and the increased electrification of homes and buildings. Companies like Canadian Wire Wizards regularly see steady demand for qualified electrical services across residential and commercial projects.

Ontario is home to many well-established electrical contracting firms operating at different scales. There is no single company officially recognized as the “biggest,” as size can be measured by revenue, workforce, or service area. Canadian Wire Wizards focuses on delivering dependable, professional electrical services rather than competing solely on company size.

A licensed electrical contractor is a business authorized to perform electrical work in a specific province or territory. The contractor employs certified electricians and is responsible for compliance, safety, and regulatory requirements.

The cost of hiring an electrician in Ontario depends on the nature of the work, location, duration, and materials required. Residential repairs, upgrades, and installations may be priced differently based on complexity.

Canada follows the Canadian Electrical Code (CEC), published by the Canadian Standards Association (CSA). The CEC establishes national requirements for electrical installations, and provinces enforce and adopt them through local regulations.

A full electrical inspection involves reviewing electrical components, including panels, wiring, outlets, grounding, and circuit protection, to assess overall safety and compliance with applicable requirements.

Homeowners can access a range of services, including electrical installations, upgrades, repairs, lighting improvements, and system troubleshooting for residential properties.

Yes. Electrical work is commonly completed during renovations to support layout changes, new lighting, added outlets, or upgraded systems, and is often coordinated with other trades.

Many upgrades can be completed with minimal disruption when appropriately planned. Work is typically staged to maintain safety and reduce downtime wherever possible.

If your home struggles to handle newer appliances, home offices, EV chargers, or smart technology, an electrical assessment can help determine whether improvements are needed.
