Ontario HCP category ask for job offer.
As you mention NO for LMIA and still you got NOI then its wasn't a system glitch.
You can go ahead with OINP application and start gathering your documents.
Thanks dear .. I just want to check one more thing I have relized that by mistake I put yes where they have asked for that Have I working for year on current work permit for this employer? It should be No .. but in details i put right time to start my job and thats why I am not getting any CRS score for canadian experience as well . Is it required that for valid job offer you must have worked for year for the same employer.
I am having valid job offer from ontario employer as full time and for indeterminate time in IT NOC.
