That's a bit of a tough question.
You can read in some of the media about Chinese investors who go into Africa or Brazil, buy the land, and set up the entire infrastructure to move the product that's produced right out to the ports and back home to China.
Now, the amount being bought I don't think threatens it like that right now, but let's face it, some people would argue, “Hey, it's my land. I produce my product. There are no rules. I can do what I like.”
I'm not sure there's legislation currently that would say you can't do that in Canada.
