Very good and easy experience with setting up the electrical for an outdoor sauna. He even followed up after the installation with additional advice on optimizing sauna temperature after the installation. Good communication, punctual, and professional service.

Mark did a repair on the wiring of our house. He communicated with us well ( he was calm and patient with us) and he got the repair done quickly. We have recommended him to our real estate agent after he finished our work. Highly recommend him!

We had Leonard Electric do work for us after we purchased a house, updating the aluminum wiring and most of the light fixtures. All the work was done on time, they were very professional and easy to work with. I would highly recommend them.

Leonard Electric completed work on my island cottage. There was no difficulties with getting an estimate completed on the island. The work was completed efficiently and at a high quality of workmanship. Owner Mark Leonard was very informative, friendly and easy to work with.

Before you hire an electrician in Ontario

Yes, twice over. The person needs a 309A Certificate of Qualification; the business needs an ECRA/ESA Electrical Contractor Licence.

ECRA/ESA Electrical Contractor Licence

A seven-digit number that must appear on advertising, vehicles, quotes and invoices. If you cannot find it on the quote, ask - a licensed contractor is required to provide it.

Verify with: The Electrical Safety Authority publishes a contractor lookup at esasafe.com.

Verify with: Skilled Trades Ontario maintains the public register.

ESA notification (the permit) for the specific job

Most work beyond replacing a light fixture requires the contractor to file a notification with ESA and have the work inspected. You should receive a Certificate of Acceptance when it passes. Keep it. You will want it when you sell.

Verify with: ESA confirms whether a notification was filed for your address.

General liability insurance and WSIB clearance

Two million in liability is standard. Electrical fires are the reason this is not a box-ticking exercise.

Questions worth asking

What is your ECRA/ESA licence number? (Then look it up before you sign anything.)
Will you file the ESA notification, and is the fee included in this price?
Will I receive the Certificate of Acceptance when the work passes inspection?
Is my panel at capacity? If this job needs a service upgrade, I want to know now rather than halfway through.
Who is physically doing the work - a certified electrician or an apprentice under supervision?
