US Begins Ban on $1 Billion in Canadian Imports

The United States began enforcing a ban on Canadian imports worth about $1 billion early Tuesday, a move likely to deepen tensions between the two countries.

The restrictions bar a range of Canadian goods from entering the US market, including alcoholic beverages, dairy products and motorcycles.

The action comes against a backdrop of already strained relations between Washington and Ottawa. Its implementation adds a new trade dispute to those tensions.

The available details do not specify the grounds for the ban, how long it will remain in place or whether Canada plans to respond.
