ESA Electrical Inspection in Ontario: What Oshawa Homeowners Need to Know

ESA Electrical Inspection in Ontario: What Oshawa Homeowners Need to Know

November 14, 20252 min read

Whether you’re upgrading a panel, installing an EV charger, or renovating, Ontario law requires many electrical projects to be inspected by the Electrical Safety Authority (ESA). For homeowners in Oshawa, understanding this process is key to avoiding costly delays or compliance issues.

This guide explains when inspections are needed, what to expect, and how CFI Electric Ltd ensures your work passes the first time.

What Is an ESA Inspection?

The Electrical Safety Authority is Ontario’s regulatory body for electrical work. Its job is to ensure all electrical installations are safe and code-compliant. An ESA inspection verifies:

  • Proper permits were obtained

  • Work meets the Ontario Electrical Safety Code

  • Safety risks (faulty wiring, improper grounding) are addressed

Without a permit and inspection, you may risk:

  • Insurance issues if damage occurs

  • Legal liability if a fire or injury happens

  • Problems when selling your home

When Do You Need an ESA Permit or Inspection?

Common projects that require permits and inspection include:

  • Electrical panel upgrades or service increases

  • New wiring or circuits added

  • EV charger installations

  • Hot tub, sauna, or pool wiring

  • Major renovations or basement finishes

Minor repairs (like replacing a light fixture) typically don’t require a permit, but check with your electrician to be sure.

How to Prepare for an ESA Inspection

1. Work with a Licensed Electrical Contractor (LEC)
Only licensed contractors can legally file notifications and permits.

2. Provide Clear Access
Make sure panels, outlets, and work areas are open and easy to inspect.

3. Keep Documentation Ready
Plans, load calculations, and equipment specs help inspectors verify work quickly.

4. Ask Questions Early
A good contractor will explain the process and prepare you for any requirements.

How Much Does an ESA Inspection Cost?

Inspection fees vary based on project size and complexity. For most residential projects, expect $79 – $200 for permits and inspection【web†source】. More complex projects (condos, large service upgrades) can cost more.

Tips to Pass on the First Try

  • Use a licensed electrician familiar with ESA requirements

  • Avoid DIY or unlicensed work—it will fail inspection

  • Address any deficiencies quickly

Passing the first time saves money and stress.

FAQs About ESA Inspections

  • Can I skip an inspection?
    No. It’s required by law for most new electrical work in Ontario.

  • How long does it take?
    Simple projects may be same-day; larger jobs require scheduled visits.

  • Does ESA provide certification?
    Yes. You’ll receive a Certificate of Inspection for your records.

ESA inspections protect your home, your family, and your investment. By working with a trusted licensed electrician, you ensure your project is safe, legal, and ready for the future.
