Just to be clear, when you say 're-create the profile', you mean 'withdraw' the express entry profile, 'delete' it and create a new profile and submit it right?It is not just true but a requirement of OINP Nomination to re-create file near to dates when they send NOI. So, when in future OINP will update their website that they have re-opened HCP stream then all candidates without NOI will have to recreate profile to be selected. No need to re-create at the moment.
I hope this will help. Good Luck.
