Here's why: Chapter 19 allows Canada to bypass the U.S. judicial review process when the U.S. government imposes antidumping and / or countervailing duties on Canadian products
imported into the United States, as has been the case repeatedly
with softwood
lumber, for example.
Apparently, there's a $ 400 million - dollar trade imbalance
with the US and President Trump is looking at slapping embargos on
imported goods from Canada, including
lumber.
