In my neighbourhood we don't have any overhead wires. They're all buried - phone, cable and electric. You don't notice it until you pass through a neighbourhood where they're not and that comes to your attention immediately.
Maybe it's time you folks in Eastern Canada went underground because the crippling ice storm you've just endured may become a routine occurrence. A Toronto Hydro study last year predicted just that.
I saw a great explanation of how the east got hammered on the weather segment of BBC News. It was -7 in Toronto while, 400 miles to the south, if was +20. That's the sort of thing we get these days thanks to the Polar Jet. Where the two met it created a massive ice storm. Being slow moving, west to east, it built up enough to bring down trees and hydro lines.
According to the G&M story, however, your utilities figure going underground is just too costly. They would prefer to adapt by replacing old wires and focusing on pruning trees. Besides, they argue, putting that wiring underground would just leave it vulnerable to future flooding (that must be their other study).
Oh well, good luck. Keep your chins up and remember, climate change is a hoax.
