Security and Trade will be decided by the USA and not Canada.
I dealt with ITARS for defence trade and it knowingly pushed aside the Canadian charter of rights about dual and citizens from watch list countries not allowed to work in US held technology. Not one company or politician pushed back and just bent over and took it for the bucks. Don't ever tell me the Canadian government will protect anyone in Aerospace defence as I saw it first hand, help my hand up and complained and was just ignored by everyone in the talks
