Ontario Electrical Safety Code Training

Ontario Electrical Code

Our 12-Hour Ontario Electrical Code Live Online Training course will cover all the Ontario amendments made to the 2018 Ontario Electrical Safety Code, adopted recently in 2020. In fact, the course is intended to do a lot more than instruct about what changes have taken place since the last Ontario Electrical Code.

This web-based Ontario Electrical Code training course covers the same curriculum as our traditional in-person 2-day training course.

You can access the live online training through our web-based platform from your own computer. You can see and hear the instructor and see his screen live and ask questions.

You can interact and ask questions. The cost of the training also includes 7 days of email mentoring with the instructor.

The 2018 edition of the Ontario Electrical Safety Code – which includes the Canadian Electrical Code Part 1 plus several Ontario-specific amendments – reflects changes in technology and the marketplace, and incorporates feedback from stakeholders, technical reviews and new safety insights. The new edition includes changes designed to enhance electrical safety and protect workers and the public including:

  • Re-write of Section 10 requirements for bonding and grounding have been reorganized and reduced in size with some changes that will improve safety and simplify the installations;
  • Expanding the use of Tamper-resistant receptacles in educational facilities and hotels/motels;
  • Requirements for installing an identified (neutral) conductor at each control (switch) location of permanently installed luminaire;
  • Alignment with the Ontario Building Code to prevent the installation of high-voltage conductors over buildings;
  • Providing of adequate working space for electrical workers to undertake necessary repairs, maintenance and installation of transformers greater than 50kVA;
  • Prohibiting of installation of cables in concealed locations in corrugated roof decking
  • Adding requirements for Energy Storage systems; and
  • Facilitating the use of Power over Ethernet to provide a pathway for sources of electricity.

This course, conducted by one of Canada’s leading experts on the Ontario Electrical Safety Code, will help electrical professionals on the effective application through an improved understanding of the intent of the rules. Also, our course will instruct electrical professionals on how to access and navigate through the Ontario Electrical Safety Code in a cost-efficient manner. The Canadian Electrical Code is the basis for all provincial and territorial electrical codes in Canada, including the 2018 Ontario Electrical Safety Code. Most provinces adopt the code, without changes, while other provinces, like Ontario, add their own amendments. In the specific case of Ontario, there are many amendments that you need to know.

Designed and delivered by Larry Cantelo, one of Canada’s leading experts on Ontario Electrical Safety Code and Canadian Electrical Code interpretation, the course will instruct not only on the latest code changes, but how to understand what the rules are and how to access the code with ease. Some people spend endless time searching for the rules that they need. This course will teach what you need to know, quickly and accurately. Our instructor will demonstrate how to find the answers you need in a few easy steps.
