Thank you @sharjeel91 for your reply , I Graduated on August 23 2019.@jweekend: its other way around, either you made a mistake you dont know what are you talking about. TRV is just a visa to enter and permit allows you to stay in canada ( whether its study or work)
For your problem, below governs here:
"If you finish your studies early, your permit will stop being valid 90 days after you complete your studies, no matter what day is printed on the study permit.
You’ve completed your studies on the date your school first notifies you by completion letter, transcript, degree or diploma.
You must provide proof of the date your school notifies you, or the date you get your degree, diploma or certificate. If you don’t have proof, we’ll use the earliest issue date on the document. We may confirm this date with your school."
So the question is when did you finish your studies?
Also, how does your COOP permit and TRV have different expiry as compared to your study permit. Did you apply for study permit extension separately? did you finish your studies later than you expected before, cause when CIC issues final study permit they add 90days to expected graduation date.
I never had any extension for neither Study permit or TRV. Initially i got 4 year permit and visa. and they expired on above mentioned dates.
Interesting thing - Upon calling IRCC, their system indicate that my study permit expires on August 15 2019, but my permit says elsewise. When i tell them - they looked deeper into archive found another file matching same date as printed on my study permit.
