First time in a long time last Monday I did a landslide-TB security check at Pearson. Yeah.
Quite a maze.
Someone else mentioned here that TB security is being reworked, or under construction. I saw little evidence of that (I'm sure there was some, but nothing major, airports and hospitals always have some construction I ignore). But the minor construction and NEXUS maze could be step 1 to a major project.
Or they are just messing with us because they can.
