Air Canada has a terribly spoiled reputation on all fronts and capped this episode by leaving the pax waiting in a snowstorm.
That must be one of the stupidest comments I have seen in a while!
I'm sure Air Canada planned with the Halifax airport management to have all its equipment not available at that time, on a Saturday night and also told its pilots to crash the aircraft in Halifax on a cold winter night in very windy/snowy conditions on purpose so as to freeze their passengers and get bad publicity out of it… Brilliant!
