Same here. I've sent my package and it was received on December, 21, but I'm still waiting for AOR.
I called them twice, all they told me was to be patient.
I registered in EE, got invitation from OINP, sent all the documents in December, 21.
Still no confirmation (90 days is a myth for sure).
I called two times and the only thing they advised - "to wait a bit more and to be patient"
:(
