Your application has already gone through all the major steps, including background checks, final decision, and even the issuance of the COPR, which is the final approval document. If your COPR is already available in your online account, that generally means your application is not delayed, and there is no issue with it. Sometimes, applicants do not receive a portal 1 (P1) email if they already have the COPR generated, or the communication may simply take a bit of extra time to be sent out. Since you already called IRCC and were told that all checks are completed, there is no indication of a problem. At this point, the best step would be to monitor your account regularly, ensure you check your email—including your spam or junk folders—for any correspondence from IRCC, and if a long period passes with no update (for example, more than a few weeks), you could consider raising a webform inquiry for reassurance.
