An import ban covering certain Canadian alcoholic beverages, dairy products and motor vehicles took effect in the United States on Tuesday. The measure, enacted through an executive order signed by President Donald Trump, targets goods worth approximately $1 billion.
The ban is not expected to have a major economic impact compared with the $880 billion annual trade volume between the United States and Canada.

Washington justified the measure as a response to discriminatory treatment
U.S. Trade Representative Jamieson Greer said the measures were a direct result of Canada’s discriminatory treatment of critical American exports.

The decision marked a new phase in the ongoing trade dispute between the United States and Canada, which have long been allies and trading partners.
Reciprocal tariffs take effect
The U.S. administration announced in July that a 50 percent tariff would be imposed on certain Canadian products, and the tariffs took effect on Aug. 22.

The Canadian government responded by imposing tariffs of 15 percent, 25 percent or 50 percent on certain U.S. products. The Canadian tariffs took effect on Sept. 8.
