As someone who has gone through this stream (HCP), OINP Ontario seems to have a window into CRS scores FSW draw or range of scores. Usually they conduct draws in the lower range of future FSW draws. But i can't believe next FSW draw could be at 477 CRS.
January 2018: Retake IELTS, create account immediately get NoI from oinp. Don't want to take Ontario path as my CRS is 436 and EE draws are running 441-445. April 2018: Reluctantly accept Ontario nomination as CRS doesn't come down on the last day, submit all documents.
I receive NOID in June. Some back and forth with Ontario and finally nomination in July end. Unlike the general idea PNP takes a long time to process you eventually get the documents but the process is slow. I am grateful for having had that route and having a way to make it to Canada.
So people who are thinking they will also get an fsw ITA and so will not accept ONIP keep everything ready the scores might not come down in the 45 days window.
