This is a safer call tbh, if you somehow mess up your IRCC documentation and get rejected, you can always get OINP ITA renewed and get those sweet 600 points againYes, had to as my OINP is in DIP stage, and as per the facts shared here, only one application can be active at one time.
And yes, I am limiting myself to Ontario but don't see myself going anywhere else at the moment, and it gives me the cushion of 600 points compared to the federal ITA.
