I think landing in a different province would be okay, say, if it's a transit, or a short visit or something. But admitting to the border agent that you will be working in Halifax, after trying to land as an NL nominee, that's problematic, because you need to have an intent to live in NL after NL PNP, and choosing to work in Halifax right after landing contradicts that.But that answers some people's question. I saw some posted if they choose to land and live in a different province, would that affect their PNP. I think the answer is that depends.
