yes. it happened to me. i kept calling almost everyday until i got a nice agent who told that my request was rejected while ago. it was just frustrating that no one told me anything.
Hi guys, I passed the test mid-October and today when i checked the tracker my background check was marked completed as of today. any idea when i will get invited to take the oath?
you could make a freedom of information request to Canada Border Services Agency. They might have your entry and exist records. As far as I know they have been collecting them from airlines since 2016. Good luck.
