Does a Designated Master Electrician have to be on a work site?

No, the Designated Master Electrician (DME) does not have to be on site. They do need to ensure that electrical work meets the requirements of the Ontario Electrical Safety Code. They are responsible for direct supervision and personal planning. The Guideline to the Duties and Responsibilities of Licensed Electrical Contractors (LECs) and Designated Master Electricians (DMEs) gives examples.

Licensed Electrical Contractors must have at least one Designated Master Electrician, but that doesn’t mean there has to be only one. Think about how many you need to provide the direct oversight your company needs.
