YYZ T1 Transborder - Punishment for the privilege
Having to walk around the back of T1 pre-clearance zone to get to the Nexus / VT line has always been a bit of a pain. Now the turn right by AC special services is cordoned off and instead people are being sent down the long hallway that runs by the staff checkpoint. Yep, another 200m+ just to avail oneself of the VT privilege.
The 2nd time around I just ignored the barrier and went around the stanchions.
