Do not think this case was that slow @All ...A bit slow but moving!
Please update the OINP Post NOI Tracker: https://myimmitracker.com/en/ca/trackers/post-noi-2017-ontario-human-capital-priorities-stream-tracker
I submitted on 13th of July (got relatives in Ontario too and 10 years of experience )...and still in the submitted stage ...Some people are in the submitted stage since the 2nd of July!
In general ...I consider anyone applying in July and got a status change from submitted to assessment in less than 10 days to be lucky...or there are other background criteria we are not aware of ...
