Canada Is Imposing Retaliatory Tariffs On The U.S.

President Trump reimposed a 10% tariff on Canadian aluminum imports to protect US businesses, citing a substantial increase in imports. He signed a proclamation to defend American industry, claiming Canada was unfairly impacting US jobs. In response, Canada's deputy prime minister deemed the move unwarranted and announced countermeasures. The tariffs were reinstated shortly after the new US-Mexico-Canada trade deal took effect.
