The list of U.S. products Canada will target for trade tariffs. Please note table 1 products at 25% fin.gc.ca/activty/consul…
Canada is planning to tax U.S. steel used in Canadian auto-manufacturing at 25%
That *imported* U.S. steel, is actually the U.S. auto-steel shipped just across the border into U.S. owned auto and vehicle manufacturing plants that are located in Canada.
The net result will be (after efficiency and profit offsets) higher actual end-line production costs for Canadian products within those U.S.-owned auto/RV/vehicle plants. 👍
...and then, if Secretary Ross so chooses, the finished product, made from the (originally U.S. produced) steel and aluminum raw material, could be taxed again upon entry into the U.S. 👍 A double whammy per se'.
Making the price of that auto/motorcycle/RV/Vehicle etc. feel double the impact of the tariff. 👊
Using 👍 and 👊b/c how long do you think it will take a U.S. manufacturer to run the cost analysis, & realize it's just cheaper to keep the U.S. raw material in the U.S. and assemble the U.S. raw material into a U.S. finished good without worrying about the Canadians? 😀🇺🇸
As soon as the financial benefits (lowered Canadian $ etc.) is offset by higher countervailing duties, simply as an outcome of assembly/manufacturing *location*, the U.S. owned company exodus from Canada begins.
Which showcases the brilliance of lowering the U.S. Corporate Tax rate in December 2017 (below Canada), which has now become increased leverage in this trade dispute. cbc.ca/news/business/…
If you own any Canadian assembled engine driven product: car, boat, RV, motorcycle, mower, etc. Go look at the oil pan closely. It will be stamped "made in china". 
As a stand-alone nation Canada just doesn't produce much steel. [Excluding the U.S. auto-steel imported] Most of what the Canadian manufacturers use is fabricated steel imported from China.
