Indefinitely?

Okay. So: I awake at 7, am on the tube by 9 with my luggage, I arrive at Heathrow at 10:45, wander across what must be several time zones looking for my check-in area, wait twenty minutes in line, only to find out from the nice AirCanada lady that my flight has been delayed indefinitely. I'm hoping by "indefintely", they mean "one hour," and not, "you're never, ever leaving," or worse: "take the tube back home for another hour and a half, then come back tomorrow. " That would make me cry.

Why can't WestJet fly to the UK?
