How Do You Become Certified in Ontario?

  4. Carry public liability and property damage insurance with a minimum coverage of $2,000,000.

  5. Register with the Workplace Safety and Insurance Board, if mandated under the Workplace Safety and Insurance Act, 1997.

  6. Fulfill tax obligations by filing returns with both the Ministry of Finance and the Canada Revenue Agency. Additionally, any taxes, penalties, or interest under the Excise Tax Act, Retail Sales Tax Act, or the Corporations Tax Act must be paid or arrangements for payment must be made.

  7. Have no outstanding debts to the ESA unless arrangements for payment have been established.

What Are Their Duties?

As a licenced electrical contractor, you'll be required to:

  1. Ensure all electrical work complies with relevant laws, including the Electrical Safety Code, health and safety regulations, employment standards, consumer protection laws, and business tax and practices.

  2. Designate one or more Master Electricians to perform electrical tasks on behalf of the contractor.

  3. Will not appoint a Master Electrician who would simultaneously serve as the designated Master Electrician for multiple electrical contractors at the same time.

Do Electricians Absolutely Need to be Licenced in Ontario?

Yes, it is absolutely necessary. Obtaining a licence is mandatory for Electrical Contractors and Master Electricians to do electrical work for hire in Ontario.

Electrical Contractor Licence vs Master Electrician Licence

Licenced electrical contractors are either individuals licenced as master electricians or those who employ master electricians and are registered as contractors. They are required to maintain liability insurance, handle construction permits, provide project estimates, hire and supervise licenced electricians, and guarantee the quality of the work through a warranty. They can be sole proprietors or part of larger firms handling multiple commercial and residential projects.

In contrast, licenced electricians are typically the professionals performing the electrical work under the supervision of electrical contractors. New construction projects specifically require a licenced electrical contractor to oversee and/or execute the work, ensuring compliance and safety standards are met.

What Is the Electrical Safety Authority (ESA)?

The Electrical Safety Authority (ESA) regulates and promotes electrical safety in Ontario, aiming to create an environment where people can live, work, and play safely without electrical hazards.

To achieve this, ESA anticipates, identifies, and targets the leading causes of electrical-related harm; verifies compliance with Part VIII of the Electricity Act and its associated regulations; promotes awareness, education, and training to inform the public about potential electrical risks; and collaborates with Licenced Electrical Contractors, utilities, manufacturers, safety partners, and other stakeholders to enhance electrical safety across Ontario.
