As a result of the September 11 attacks , the airspace over the United States was shut down . Aircraft over the North Atlantic and Pacific bound for the United States were therefore diverted to Canadian airports . Being the only major airport in Western Canada with the ability to receive large-body planes , Vancouver International Airport accommodated 34 of these flights ( 3rd highest after Halifax and Gander ) amounting to a total of 8,500 passengers
