In the telephone universe, aerial cable has a lifespan of about 25 - 35 years, whereas underground cable, properly installed, has a lifespan of 125 years. Even without ice storms occurring.
Bottom line: if you're planning sustainable community, put all of your electrical and telecoms cables underground, below the frost line, in substantial conduits.
Yes, for sure. Ottawa, about 100 miles from Montreal, was also hit by the ice storms, but made it through spo much better as its power distribution is mostly underground cable. Not sure of why the difference, likely as Montreal is in a poor province, but it sure helped Ottawa.
I guess most U.S.A. power distribution, at least cities, is underground as they can get hurricanes and tornadoes, and of course they have a lot of affluence to afford it.
