The United States imposes a ban on imports of alcohol, motorcycles and other Canadian products

The United States is banning a number of Canadian products, including liquor, dairy products and motorcycles, as its neighbor’s retaliatory tariffs on American goods come into effect.

In a series of executive orders on Tuesday, US President Donald Trump claimed that Canada is “discriminating” against the United States and outlined the import ban, which will begin on September 29.

Earlier on Tuesday, Canadian Prime Minister Mark Carney said in a video address that his country’s move away from the United States as its largest trading partner “will come at a cost.”

Both U.S. and Canadian officials have said they would like to reach a trade deal, but no new talks have been scheduled since negotiations collapsed in late August.

The BBC has contacted Carney’s office for comment.

The new White House sanctions are the latest blow in a months-long trade war between the United States and Canada. The parties have historically been close allies, and each is a key trading partner for the other.

Overall, more than two-thirds of Canada’s total exports go to its neighbor.

On the other hand, Canada is the second trading partner of the United States, after Mexico, although its exports are much more diversified.

Business owners on both sides of the border have expressed fears about the consequences of the trade war. Many expect that the prices of goods will increase and the number of customers will decrease.

Last month, the White House imposed 50% tariffs on around $20bn (£14.8bn) of Canadian goods after several rounds of talks collapsed.

Those tariffs affect sectors such as Canada’s furniture and wine industries, as well as sports and fishing equipment companies.

Canada responded with dollar-for-dollar tariffs on American goods such as steel, clothing and furniture. The counter-rights went into effect after midnight on Tuesday.

Canada is “discriminating” against American companies by restricting American products without doing the same for the same products from other countries, the White House said in announcing the new import restrictions Tuesday.

Imports of some products, such as whey and non-alcoholic beer, have been banned entirely, while import taxes have been increased further for others, including cheeses and motor boats.

On Monday, Trump hinted at more trade restrictions ahead and warned Canadian aircraft company Bombardier that it would no longer be able to sell its products in the United States unless it moved manufacturing there.

Trump has long believed that tariffs will help reduce trade imbalances between the United States and other countries, but his sweeping tariff scheme has upset many of the United States’ traditional allies.

Some Canadians have led a mass boycott of American products such as alcohol, which have disappeared from some stores after Trump launched his global tariff campaign last year.

Trade expert Deborah Elms of the Hinrich Foundation told the BBC that the import ban could have a “strong” impact on any Canadian business with American buyers, although early estimates show a “modest impact” that would affect goods valued at around $1 billion.

Canada is likely to “stay the course for now” and adjust its business support measures to take into account the latest U.S. measures, Elms said.

“The bigger question is what it will take to get the two sides back together. The language of these proclamations, for example, is not helpful in getting to the negotiating table,” he added.
