Good luck to you, I feel IRCC is returning files for non-sense reasons now, they returned my file after 8 months due to missing PCC, where as IRCC website says they will not return / reject the file missing documents and they specifically mentioned PCC, still they rejected mine after 8 months. I reapplied in Canada class now. its more than 4 months and no response. IRCC's system is failed, basically it is more than a year now, when I started spousal sponsorship file but as of today I have not received acknowledgement letter. Overall, it is terrible.
