Ms. Freeland is right to correct misinformation but, at the end of the day, other the Trump Administration will focus on other aspects:
1. Haven experienced several recent setbacks, they need a win to steady moral. The upcoming NAFTA negotiations will be of high interest to their support base and begin soon.
2. If their international trade policy is more than mere transactional machismo, it is implicitly 18th-century Mercantilist with Canada and Mexico envisioned as economic hinterlands to the US's metropolitan centre.
3. Canada may not run a net trade surplus but we do in certain industries (softwood, etc.) and the US will cherrypick for decisive wins.

In short, Canada needs its own detailed list of unfair US trade practices with which to bargain and must be cultivating trade allies and new markets.
