Hire an immigration lawyer. IRCC is well known for blunders like this.Last Jan 24th 2023 I received a PPR (passport request) for my oultand dependents. But I did not receive portal email confirmation. We sent the passport in Jan 25th. Yesterday my dependents got their passports back without stamp and with a letter saying that they should have not sent those passports because IRCC did not ask for them. WTF.
