Trump threatens 50% tariffs on Canadian vehicles and parts

US President Donald Trump threatened to raise tariffs on all Canadian cars, trucks, and auto parts to 50 percent starting January 1st, following the collapse of weekend trade talks. The move escalates pressure on Canada after negotiations failed. The proposed trade deal would have cut tariffs on Canadian cars and light trucks from 25 to 15 percent and on aluminum and steel from 50 to 25 percent. Talks collapsed Friday over disputes, including whether relief applied to medium or heavy-duty trucks. Canada plans retaliatory tariffs on US goods starting September 8th. Auto executives expressed skepticism, noting Trump has previously made threats that never materialized, and suggested the move could aim to restart negotiations.
