And I thought doing a transborder connection at YVR was a hike. Just made it through the marathon than its the YUL domestic to transborder connection. It seems like kiometers down corridors that can best be described as dreary. And although the bags are now transferred and don't have to be picked up, they still must be visually checked by US Customs as in YVR. This can mean another wait until they reach the transit area. So, even though there is NEXUS (unlike YVR) it may not speed you through the connection. One thing YUL could do to make this a bit more bearable is to have some small luggage carts at the start of the pathway because shoulder bags get heavier after the 2nd or 3rd kilometer!
