+update+ Update to the post:
Today I tried use birthday information to link the PR card application to our GCKey accounts and luckly found it really has one PR card application (different application #) started on the same day June 10. we didn't received CoPR email/letter so far, didn't submitted anything after the passport, photos returned on Jun 11.
Does anyone can share what will be next step? shall we be requested to submitted the CoPR (not coming yet) + photo again? or will get PR card directly?
today we got CoPR email from Etobicoke IRCC to request CoPR letter + photo for print PR card.
