Teneris will lay off 40 workers at its TenarisAlgomaTubes plant in Ontario and adjust output there because of the U.S. tariffs on steel and aluminum imports.
In a lawsuit filed Wednesday the American Institute for International Steel and two of its member companies argue that the US president’s tariffs on steel and aluminum imports are unconstitutional.
So far, Trump has taken little action beyond tariffs of 25 percent on steel and 10 percent on aluminum on imports from China, the European Union and other countries.
