Oh, so he will be visiting Russia first then? The US cannot afford to alienate Canada on NATO so there is zero chance of any real pressure on that front. More interesting will be trade negotiations. Trump will need to at least do some hand waving here and some level of renegotiation seems inevitable. The main thing the US really wants is unfettered access to Canadian water. If Trump is able to get some intelligent people to the table for the US this is going to be a brutal experience for Canada. It will be a very difficult negotiation in which Canada holds relatively few cards.
