Montreal has had all of its runways rebuilt, including 24 right at 13,600' in length. Also, one of the gates has been modified with dual level bridges to disembark passengers from both levels simultaneously.
We've seen all sorts of aircraft in Montreal, I'm sure you know it'* the 'home' of Bombardier, with Pratt & Whitney, Bell Helicopter Texron, CAE and Heroux all nearby. Here'* a picture of the once a week visitor to the airport;
The Antonov carries fuselages for one of the Bombardier Regional Jets from the Short Brothers factory in Ireland.
We've also had B-52 Bombers here often, they need a wide runway with the landing gear on the ends of the wings, not to mention they take a few feet before they rotate for take off.
