Maybe it's a question of clarity of language. You specifically picked out these 10 countries. Surely you can't believe that Canadians shouldn't be allowed to invest in places like Hong Kong, Ireland, and Singapore—three of the countries you named. This is legal investment, with taxes paid on that investment.
I want to be clear that you're not suggesting that Canadians shouldn't be allowed to invest legally, with open investment in those areas, and pay taxes on that investment.
