There are risks for Canada based on a broad interpretation of Trump's statements, but nothing specific. In terms of what should be the main concern, jobs related to auto production, the greatest risk lies with production in low wage countries and countries that do not allow equal access to foreign markets for US produced cars (and more broadly, goods generally). In this regard, Canada's risk is fairly low, Mexico's high. Western European countries low, Eastern European countries relatively high. Japan's risk higher than Canada, but lower than China. 

The uncertainty is understandable, but the sky is fall, Chicken Little approach to stories is wholly unjustfied at this point, and is tabloid journalism.
