Ontario Electrical Safety Code Training

Ontario Electrical Code

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.

Our 12-Hour (2 Day) Ontario Electrical Safety Code Live Online instructor-led training course will cover all the Ontario amendments made to the 2021 Ontario Electrical Safety Code. 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.

The Ontario Electrical Safety Code, Ontario Regulation 164/99, is comprised of the Canadian Electrical Code Part I (CEC) together with specific Ontario Amendments. Development of the Canadian Electrical Code Part I is led by the Canadian Standards Association (CSA). It is developed in close consultation with volunteer technical committees and subcommittees reflecting expertise from across Canada, including ESA. After review, the provincial government then adopts the CEC, with additional amendments specific to Ontario.

The Ontario Electrical Safety Code is mostly a technical document and is prescriptive in approach. The Code describes the standards for electrical installations, products and equipment in Ontario in detail.

The 2021 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.

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 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.
