It's been such a confusing journey for me to be honest. My consultant told me that I need to renounce my PR status before I can submit my documents for OINP.
As a minor, my family applied for Immigration back in 2000. We got selected and entered Canada, but my parents decided it wasn't for them due to personal and professional reasons - we came back in literally 15 days. We never applied for our PR cards but did get an insurance number (SIN).
I emailed the high commission in Islamabad and they said they couldn't find a record - however my consultant still insisted that I renounce my status and ensured me that it wouldn't affect my nomination!
I'm really hoping that's the case. Fingers crossed
