Kaden and Victoria Shearer

Oosterhof Electrical was great to work with from start to finish. From the initial quote to the completion of our project, their communication was clear and consistent, their pricing was fair, and the work was completed efficiently and on time.

Blair Frost

We've used Oosterhof Electrical for 3 projects on the house, and we will continue to be faithful life-long customers because they've earned it. The work is alway immaculate, the administration is seamless and efficient, they're fully attentive to your every request. Everyone is friendly and pleasant to deal with. It's locally owned and operated!

Second time using Oosterhof. Once again very pleased with the work. Len is very easy to work with, great communication and always shows up on time! The crew was very professional and their work was done very neatly, which I appreciate. I will continue using them and highly recommend!

Marjorie Gallerneault

We have been waiting since Dec 2nd for a gas quote to complete the quote for a Kohler generator. I followed up on Dec 17th. Still nothing. I have advised Kohler of the poor service.

Ronald Macknight

They do great work. Showed up on time. I’am on an island which was a little more difficult but everything went well. Very pleased. Highly recommend them

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.

Certificate of Qualification, 309A Electrician

Held by the individual. A licensed contractor employs certified electricians and apprentices; the apprentices work under supervision.

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?
