Finally, received my COPR on Wednesday, April 21, 2020. Would like to share the timeline of my application.
Category: CEC-inland, 1 applicant
Processing Office: Vancouver BC
May 18, 2020-AOR
June 19, 2020-1st Request Letter for updating application fees
July 8, 2020-2nd Request Letter for IMM5406-Aditional Family Information Form
July 13, 2020-Medical Pass/Receive Biometrics Collection Letter
Oct 13, 2020-Biometrics Pass
March 22, 2021-Ordered AITP notes (haven't received them yet )
April 20, 2021-Eligibility Pass
April 20, 2021-Background Check Finished
April 21, 2021-Received COPR information letter
April 23, 2020-Mail the COPR information letter and two photos to the Vancouver office (CIC said it would take 121 days to process the card)
During the waiting, I received many GMs which I did not record the specific dates. I called CIC in October 2020 and November 2020, after that It quite difficult to transfer to an agency. When the day I received the copr information letter, I was not surprised, I thought it could be another GM. By the way, I received a GM on Monday, April 19, 2021. I guess it could be a sign of processing documents.
Hope this is helpful to all! Good luck!
