I read from the Facebook page that her application was returned due to a missing document. I was surprised that that her representative didn’t receive a PROCEDURAL FAIRNESS letter for a missing document. IRCC will never refused you without giving you a chance to correct some mistakes. Read the information in the ircc website regarding Procedural Fairness. I guess her representative missed out that email.
This is what the refusal letter said,
The application is being returned to you, because at least one element of the requirements of
Section 10 of IRPR is/are missing or incomplete. Your application fees, for both your permanent
resident application and work permit application under this program were not processed and are also
being returned to you. If you submitted work permit or study permit applications for your family
members in this application, these application fees will also be returned to you.
Please see the highlighted item(s) on the enclosed checklist (IMM5981) for further information
concerning why your application failed to meet Section 10 of IRPR.
Please note that a full completeness check of your application was not
performed. There may be other elements not identified on the enclosed checklist
which may also be missing or incomplete.
