Trump claimed in his letter that the new 35% tariff was a response to “Canada’s failure” to address several long-standing trade and security concerns.

President Donald Trump has announced that the United States would impose a 35 percent tariff on imports from Canada next month, while eyeing blanket tariffs of 15 or 20 percent on most other trading partners as he broadens his trade war.
