What I'm saying is no one is allowed to do any electrical work other than a qualified electrician. You say a competent worker is allowed but that is not true. No where in the OHSA book does it say that. If all you have to be is competent than why do we even have licensed electricians?

A home owner in Ontario can do their own work if they get a permit but at work, no one but a qualified person can do any electrical.
The fact that ESA overlooks this with their CSS program (so they can make money) is the problem.

Call the MOL and tell them your a competent maintenance worker in a commercial building and ask if you can do electrical work. I know the answer because I've made that call already.
