This is a conflicting issue for me.
On one hand i totally get where your coming from. I’d love to see a recladded modernized terminal building. The 1960s window wall looks very aged. YUL would better fit into the world of modern airports .
On the other hand I find airports around the world completely ignore their historical architecture. They can’t wait to destroy and rebuild with something newer. We’re one of the few airports still with the original terminal building (or close to it, the 2nd I suppose - est 1960) and it’s original interior form is still there under layers of modernization masking as a modern 21st century terminal.
Every major airport looks like it was built in the past 10-15 years it seems. The irony is we get on equally new and modern planes that take us to cities so we can visit ancient architecture and admire it. The planes we fly on too only last a couple of decades. When a model is finished they get scrapped. If we’re lucky some enthusiast aviation group may buy one model and preserve it somewhere. The 747 era is over, how many will last over the next 20-30 years so we can admire it like an old church, castle, plantation mansion or whatever? The airline/airport world never seems to care. They act like we hate history when we seem to love it.. at least elsewhere.
so.. yeah I like new modern airports like everyone. I’m just glad we’re keeping at least one element as it was originally designed.. the front facade. Its a rarity these days and people one day might just go to get a selfie in front of it because it has historical value. At least one can hope after all its part of Montreal’s history and heritage.
