Meanwhile the priority line at YUL Domestic was open at 3:05pm last Sunday and 2:50pm yesterday.

The problems with the YYZ lines are different between the two. At transborder, there isn't one long line feeding the set of doors, each security lane has its own door. And at YYZ domestic connections (2nd floor), they just don't seem to care. Which applies at transborder of course.
