We had a great experience with Thames Valley Electrical. They completed extensive electrical work on our triplex. They were punctual, professional, and offered fair pricing. I definitely recommend them and would hire again!

Thames Valley came in and replaced my electrical panel, the job went pretty quickly it seemed and there weren't any issues. My power wasn't out for very long (maybe a few hours at most) and then everything was working again. I would recommend them!

The electricians did a great job with our street lighting. They arrived when promised, did the jib within their estimated time , and cleaned up nicely when finished ,The where polite with our other condo residents. We would definitely have Thames Valley Electric back to help us with other jobs. Thank you Jim Gilmour

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.

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?
