Okay, to be honest this is beyond my knowledge.
I understand what they're saying, your misrepresentation ban has to be served outside of Canada, while you're here that time isn't accumulated.
On this, i have to let others answer, or i think you should get a second opinion from another immigration lawyer.
But the logic is sound, it's just further complicated by your TRP, and whether that gives you reprieve or not from that condition if it applies.
You need professional help.
