IMM forms for Addition of spouse Post AOR

[salviabu21]

Hello,

I recently got married and im in the process of adding my spouse to the application.

I have received a bunch of forms from IRCC, mainly, IMM 0008, IMM 5406, IMM 5562, IMM 5409.

All these forms are to be filled by the principal applicant.

My question is who would be the principal applicant in this case, me or my spouse whom i am adding to the application.
