Canadian Code: Why Should the CEC Interest Electrical Utilities? 
by Leslie Stoch

The Canadian Electrical Code Part I gives electrical utilities an exemption from the code for "installations and equipment in its exercise as a utility, located outdoors or in buildings or sections of buildings used for that purpose." The CEC Part I is "a voluntary code for adoption and enforcement by regulatory authorities." When adopted into the provincial regulations, this exemption is almost always maintained for work that falls within the scope of an electrical utility’s business.

Ask CSA: Understanding the Canadian Electrical Safety Regulatory System. Part II: Canadian Provinces and Territories
by CSA Group

Canada’s 10 provinces and three territories are the legislated regulatory authorities for electrical safety in Canada. Under the Canadian Constitution there is a division of powers between the federal and provincial/territorial governments. The federal government has jurisdiction over areas such as defense and communications while the provinces and territories have jurisdictional authority over others such as education, health and electrical safety. As a result in Canada, you have 13 separate electrical safety regulatory authorities.
