Deadline approaches as Trump plans to impose 50% tariffs on $20 billion worth of Canadian products

(NBC, KYMA) - Relations between the U.S. And Canada could deteriorate further at midnight Wednesday if Trump goes ahead with his plan to impose 50% tariffs on $20 billion worth of Canadian products.

The two countries are seeking a truce on the new taxes as the deadline approaches.

The United States and Canada have wrangled for decades over trade, poking each other interminably over sore spots like Canadian softwood lumber imports and U.S. access to Canada's protected dairy market.

President Trump's approach to dealing with Canada marks an extraordinary departure from the traditionally cooperative relationship between the two countries.

Trump has hit Canadian goods with tariffs in a push to bring manufacturing back to the United States. President Trump has repeatedly made inflammatory comments about turning Canada into America's 51st state.

Trump plans to impose 50% tariffs on Canadian products, ranging from hockey sticks to tongue depressors, alcohol to dairy.

After the Supreme Court ruled the president overstepped his authority by imposing double digit import taxes on almost every country on earth as a national emergency.

Trump last month imposed new import taxes of 10% to 12.5% on 59 countries and the European Union, which together account for 99% of U.S. imports, accusing them of allowing forced labor.

President Trump made a bold move when he invoked section 338 of the tariff act of 1930.

Never before used, section 338 allows for import taxes on products from countries that have discriminated against U.S. businesses.

Trump claimed Canada discriminates against U.S. exports of autos, alcohol and cheese.
