Your steps are right, I did not put anything in attention to because OINP instructions don't require that. After 2 days, WES notified me that the report was delivered to OINP.
As for timing, if I remember correctly, you have a score of 470 and the EE draw is tonight so you might want to wait for that before spending the $40 on WES report. Per say you have to send the WES report to OINP before they start assessing it and when they start assessing is anyone's guess. I sent the WES report just before submitting my OINP docs.
