Sorry to burst the bubble here, but standing up to the bully, as you put it, is guaranteed to result in having your face planted firmly in the ground. A better option would be to cultivate good relations. Canada is not a target at this point, so why call him out? He'll have plenty on his plate just dealing with Mexico and China, plus all the assorted international realignments that are likely to ensue. Trump might appreciate having a pleasant neighbor who doesn't run a massive trade surplus with the US. That doesn't mean you just roll over. Canada can negotiate and still maintain excellent relations if that becomes necessary.
