Do-It-Yourself (DIY) Electrical Work


Homeowners have the option to DIY electrical work in their home. However, electrical work can be incredibly complex and dangerous, and if done incorrectly, can lead to property damage and put loved ones in danger. 

Consider hiring a Licensed Electrical Contracting Business that has the equipment, training, and expertise to do electrical work safely.

Follow the Ontario Electrical Safety Code  

Before you begin your project, make sure you are familiar with the Ontario Electrical Safety Code (OESC), and dedicate time to see how it relates to your project. OESC describes the standards for electrical installations, products and equipment in Ontario in detail. Every installation, repair and replacement work must meet the OESC, as this helps keep you and your loved ones safe and ensures the electrical work is done correctly. 

Always refer to the most recent edition of the OESC, as it is updated every three years. The Ministry of Government and Consumer Services approves the new Code, and the newest edition came into effect on May 5, 2022.


Plan Your DIY Electrical Project

When you have reviewed the OESC and made plans, you can begin work on your project. Even for little jobs, you must file a notification of work (i.e., permit) with ESA before commencing work. The notification fees may vary based on the complexity of the job, but for many small residential projects can be less than $100.

Consider the following when planning your electrical project:

  • Only you can do electrical work in your home, but you must file a notification with ESA.
  • Friends, family members or neighbours cannot perform electrical work in your home.
  • If you’re a tenant, you are allowed to do electrical work inside your rental but check with your property manager first.
  • Hire a Licensed Electrical Contracting Business – it’s the safest decision.

Get Your Work Reviewed

You must get your work reviewed by ESA as soon as it is complete. The inspection process may vary depending on the project.
