I would never have thought that the TN would be at risk but if relations between the U.S. and Canada continue down the path that we're on, then I don't think it's out of the realm of possibility. I'm not sure how long it would take for the U.S. to get out of the free trade agreement but if the U.S. were so motivated, it effectively could kill the TN very quickly, even if just by policy and practice. So yes, if you can, it probably makes sense to start looking at options to get off the TN, such as the H-1B (but subject to the annual lottery), the O-1, and the E-2.
