The United States and Canada have failed to reach an agreement on trade discrimination issues in areas such as automobiles and alcoholic beverages. President Trump announced last month that he would impose a 50% tariff on Canadian imports, and Canada demanded the withdrawal of tariffs and the cessation of boycotts. The two sides agreed to continue negotiations but ultimately failed to find common ground. As a result, a 50% tariff on some Canadian imports went into effect. The Canadian Prime Minister criticized the US for changing its conditions and said he would "respond dollar for dollar," raising the possibility of a re-ignition of a trade war between the two countries.
