(Jonathan Austin/CBC)U.S. President Donald Trump's top trade official says it's "unhinged" for Canadian leaders to characterize the administration's tariffs as a trade war against Canada.In an interview with the Financial Times, Jamieson Greer downplayed the significance of the recently imposed 50 per cent U.S. tariffs to the Canadian economy and chastised Prime Minister Mark Carney for how he has described the trade dispute."Prime Minister Carney used the term 'war.' It’s not a word we use, right? We don’t talk about it that way. For us, it’s business, it’s economics," Greer told the FT News Briefing podcast. The tariffs that took effect in August apply to just five per cent of Canada's exports to the U.S., Greer said."To kind of have it whipped up into this giant thing, where we’re talking about war and economic attacks and all these things, it’s a little unhinged," he said. The podcast was posted on Saturday, before Canada's retaliatory tariffs took effect on Tuesday; the U.S. quickly further responded with a plan to ban imports of Canadian alcohol, motorcycles and several food products, starting on Sept. 29.

"It is the Canadians that came out and said, 'this is a war, this is an economic attack,'" said Greer in the interview.

"Canada chose to embark on senseless retaliation against the United States," he said. Just Asking wants to know: What questions do you have about shopping in the age of the Canada-U.S. trade dispute?
