Quoting N353SK (Reply 3): I'm not too familiar with Bombardier, but do they produce the Q400 in downsview? if they do, there's your explanation as to why it's been frequenting YYZ more often.
Yes, they do, but that's not the reason for the AN-124s. The Global Express is assembled at Downsview, and the wings plus some fuselage parts are produced in Japan. They are delivered to YYZ, presumably because the AN-124 can't get in and out of YZD.
