Wait for Transport Canada to make an official annoucement.
Any one else making a statement is probably ill informed, looking for movie rights, knows shit about what they are talking about or is making public statements to fill in gaps about their family life.
Like the threads on the attacks on London I would urge the moderators to lock these threads until a proper Air Transport release has been issued for the benefit of family members, passengers and crew.
