They do not reject applications unless it's incomplete. Moreover, they send procedural fairness letter requesting documents that they find missing. Relax back if you have replied to them.I submitted my OINP application on 26/6/2017 and received email for additional documents twice. The first time I replied I did get an acknowledgement of docs received but the second time I did not receive an email confirming the receipt of documents. The last email was sent to Ontario on July 20. Currently the status is in DIP. How long will it take for processing? If they reject ur application do they give a reason behind it ?
