Egon,
You're really are out of it in Lotus Land. The Canadian Department of Communications was scrapped many years ago and its (technical) duties were folded into a ministry that goes under the name Industry Canada. The address you gave is correct. The Canadian Electrical Code does exempt public utilities. All Provinces and Territories have adopted the Canadian Electrical Code. Slight problem is that they have not necessarily adopted the latest version of that document. Ontario does not enforce section 60 (I believe it is) that deals with telecommunications installations. Enjoy the sound of the clapping of one hand. You've got to come East more often. Vic
