DWI Canadian Border Crossing Question!! HELP

if he was on probation like some one i know and went over he wouldnt be able to come back. has to live there for 5 years or something. then coming back 6 years later. busted for some odd reason, and come back for 20 years. really sucks.
-he got over to Canada with an easy check, but when trying to come back they went through everything with crazy suspicions. they checked his car took everything out. his family was with him too. and it took hours.
Note: this was like 4-6 years ago. im sure things have changed alot.

when i go i just say we’re going Sea world. it works. and its the only question.
