Additionally it seems to be a pretty obvious failure mode to have a non-redundant power feed which your aircraft rely on, in a location where the same aircraft can damage the lines.
Well, at CYHZ, the airport is "uphill" from the road and power lines, on a hilltop about 15m above the road. You would have to be below runway elevation to impact those power lines - as was the AC airplane.

In which case, the power lines are the least of your problems....

In effect, these power lines are "buried" - about 5m below the tarmac elevation.
