What should I know before hiring an electrical contractor for a renovation?

Before hiring an electrical contractor for a renovation, confirm three things at minimum: a valid ESA licence, active WSIB coverage, and adequate liability insurance. These are not nice-to-haves — they are the baseline protections that separate a legitimate operation from someone who could leave you holding significant financial and legal risk.

Start with ESA licensing. Every electrician performing permit-required work in Ontario must hold a valid licence from the Electrical Safety Authority. You can verify an electrician's licence status at esasafe.com. An unlicensed individual cannot legally pull ESA permits, which means the work cannot be inspected, which means your insurance company may deny any claim related to that work. At resale, a home inspection that reveals unpermitted electrical work can derail a sale or result in a significant price reduction.

WSIB coverage — Workplace Safety and Insurance Board — protects you from liability if a worker is injured on your property. If an uninsured worker falls off a ladder in your home or receives an electrical shock, you as the homeowner may be held responsible for their medical costs and lost wages. Request a current WSIB clearance certificate before work begins. Legitimate electrical contractors carry this as a standard cost of doing business.

Liability insurance — specifically commercial general liability — covers damage to your property caused by the contractor's work. A minimum of $2 million in coverage is standard in the GTA market. If a wiring error causes a fire or water damage, the contractor's insurance responds rather than your homeowner's policy. Ask for a certificate of insurance naming you as an additional insured for the duration of the project.

Beyond these essentials, get at least three written quotes for any renovation electrical scope over $1,000. A proper quote should itemize the major components — panel work, number of new circuits, number of outlets and switches, lighting rough-in, and ESA permit fees — so you can compare apples to apples. Be cautious of quotes that are dramatically lower than the others. In the GTA market, licensed electricians with proper insurance and WSIB coverage have real overhead, and a quote that seems too good to be true usually reflects corners being cut on licensing, insurance, or code compliance.

Timing and coordination are critical in renovation electrical work. Your electrician needs to be on site at two distinct phases: the rough-in, when all wiring is run through open walls and ceilings before drywall goes up, and the finishing, when outlets, switches, fixtures, and cover plates are installed after painting. Miscommunication between your general contractor and electrician about scheduling is one of the most common causes of renovation delays. Establish the rough-in date early and confirm that the ESA rough-in inspection will happen before drywall is closed up — drywall installed over uninspected wiring may need to come back down.

Discuss the scope in detail before signing anything. Walk through the space with the electrician and discuss every outlet location, switch placement, lighting fixture position, and dedicated circuit requirement. Changes after the rough-in is complete are expensive because they may require opening finished walls. Take the time to plan properly upfront — sketch out furniture placement so outlets end up where you actually need them, not hidden behind a sofa.
