Master Electrician Examination Changes

Master Electrician Exam Pass Rate Changes as of Sept. 1, 2018

As of Sept.1, 2018 individuals writing the Master Electrician (ME) exam will need to achieve a minimum score of 60% in each of the three exam sections:

  • The Ontario Electrical Safety Code,
  • Worker Safety, and
  • Business Administration.


This is in addition to achieving an overall exam score of at least 70%. Previously, individuals would be able to pass the exam with an overall pass rate of 70 per cent, regardless if they failed any of the three sections. The Electrical Safety Authority (ESA) is responsible for the administration of the exam and for the licensing of Master Electricians. The exam is offered only through the ESA.

This change is being made to ensure MEs have balanced knowledge in the three competency areas deemed necessary to be an effective Designated Master Electrician. Individuals who are not successful passing the exam will need to rewrite the full exam. ESA offers the option to write the exam electronically or by paper, in English or French, and translation services are still available. The cost of the exam remains the same.

The Electrical Contractor Registration Agency Advisory Council recommended to ESA that this change be made so that prospective employers and the public can be assured that MEs have received the designation without gaps in their knowledge.
