how could I be sure the glass fibre line would be up to the task?
There are mainly two versions of reinforcement type in fiber - it will be steel rope or fiberglass strings. Fibers itself runs in the center of enforcement in a small plastic tube filled with gluey goo. On the outside fiber have thick polyethylene insulation. There is a small list of substances that could stick to polyethylene and ice is not a one of them. Diameter of 4 fiber cable is 4-6mm. Hardly a lot of ice could build up on such cable. I don't know cases when the fiber was broken with ice, it was always fallen tree or a humans driving some construction machines.
Plus the poles are owned by the provincial government owned Manitoba Hydro so not as easy to get permission to piggy back on their poles...
Talk with the people who really handle your line. May be your line is too far from province goverment. :)
In any case, more information you collect, more sensible solution you will get.
