No, I did not receive any AOR from OINP. WES ECA report was delivered before my OINP application was submitted, that's why OINP could overlook it and didn't send me AOR. I suppose they have not linked the report with my OINP application correctly. So, I should ask the investigator to check reports received in 10-13 Nov 2017.
I decided not to get delivery confirmation from WES, because they're too slow processing such requests. Instead, I've ordered another duplicate report since it is quicker and $41 is not something to worry about.
Thank you for your response, joaojr123!
