Guys, sharing this timeline just for reference:
Jan 3rd 2017: OINP Package arrived
Jan 11th 2017: Direct ITA Received
Jan 11th 2017: Emailed OINP asking withdrawal (they never replied)
Feb 1st 2017: OINP AoR
Feb 9th 2017: OINP ADR (Paystubs, Duplicate ECA, and new TEF copy)
So at that point I decide since they already cashed my money and are moving fast, why not continue?
Feb 10th 2017: Sent the ADR (Acnowledged within 2 hours, also asked me if I planned to reject the ITA)
Feb 10th 2017: I rejected my ITA and informed them (one of the hardest things I've ever had to do!)
Feb 17th 2017: I got a call from them in the morning
Feb 17th 2017: Just received and accepted my nomination
So why I preferred to go with the PNP: it feels safer because my nomination certificate is still valid and can be reused if I make a mistake and end up getting my application cancelled. So a new ITA is guarantied. Also to be honest, I needed the reassurance
lol
Good luck everyone!
