Well, I'll wait on the ADR. It seems the requests are varied.
While it is mentioned for paper based applications, this form is often requested by the visa officers. Consultants, as well as several applicants have shared their experience of this form being requested and expected when submitting Online EE in the OINP Human Capitals Stream forum amongst other PNP forums. Of course, the applicant may wait and see if any AD is required. ADRs do tend to delay the processing as mentioned by past applicants.
If you are an OPNP nominee, refer to OINP Human Capital Forum for advice. I submitted mine based on former applicants’ experience , as well as two immigration consultants’ advice.
Good luck.
