Thanks Playacaribe2 and lifeisgreat. It is interesting that it was posted on the Air Canada Vacations website, but there was no press release on the main Air Canada page (where I looked for it.) The only press release on the main Air Canada page relates to cancelling flights to Hong Kong.
That was my point initially. When I googled Air Canada cancellations, everything I pulled up related to that and Air Canada's response that they were not cancelling flights.
The fact that they turned around a day later and actually cancelled flights is baffling.
