Guys,
I follow the OINP thread very closely since I am interested for the Ontario PNP. All 400+ scores which had received a PT notification from Ontario from Oct'15 to Jan'16 are receiving their nominations now and hence are getting the addition of 600 points into their EE profile.
An ideal processing time for the Ontario PNP nomination is 3 months, however they took approx. 6 months to process the files this time because of the high number of PT nominations issued by them earlier in this year.
This could also be the reason why the CRS score is not coming down and not only that high qualified people are joining EE every two weeks. These nominations from Ontario will dry up by the end of November'16 so post that you will see the CRS scores coming down.
Also, I watched one video on youtube recently from a CIC representative who stated that from Oct'16 they are planning to draw 2000+ candidates which would bring the CRS cut off scores close to 450 or may be below that as well.
Keeping the fingers crossed as all 450+ score candidates should receive an ITA before the end of this year.
