it's called the free market you retard.  why would we continue to do business with the us i a serious manner when we can just build up infrastructure to ship shit everywhere else, and vice versa.  also, canada is in a much better position to weather a trade war.  the taxes will just be shifted to the americas an consumer even if trade continues.    why did 2008 crash happen anon? it wasn't because of stupid trade policies.
