On March 11, U.S. President Donald Trump's trade adviser Peter Navarro announced that the proposed increase of tariffs to 50% on Canadian steel and aluminum would not be implemented on Wednesday. This decision came after Trump initially ordered a 25% tariff on all steel and aluminum imports to be doubled exclusively for Canada in response to Ontario Premier Doug Ford's plan to impose a surcharge on electricity exports to the U.S. Following discussions between Ford and U.S. Commerce Secretary Howard Lutnick, Ford opted to suspend the surcharge.
Navarro confirmed in an interview with CNBC that the 50% tariff on Canadian steel and aluminum would not go into effect on Wednesday. Subsequently, a White House spokesperson stated that the scheduled 25% tariffs on steel and aluminum for Canada and all other U.S. trade partners would be enforced at midnight.
