Yes, this can be normal in some protected person and permanent residence applications.
When the principal applicant receives an eCOPR before their overseas spouse or dependent children, it does not automatically mean there is a problem. Even though the applications are linked, family members outside Canada are often processed separately and may have:
*Different application numbers
*Different UCI numbers
*Separate security, background, and admissibility checks
*Processing through a different visa office abroad
How ever there is NO dedicated portal such as GCKey or IRCC specifically for the principal applicant to monitor the spouse's or child's application.
