Canadian PM responds to lumber tariffs imposed by the US

Trudeau was responding to the announcement of new U.S. duties of up to 24 percent on softwood lumber entering from Canada.

Canada's Liberal Party leader said the two countries are economically interconnected, but it's not a one-way relationship.

"There are millions of good U.S. jobs that depend on the smooth flow of goods, services and people back and forth across our border," Trudeau said during a press conference.

He cited free trade in the North American auto sector as an example of how a typical car part can cross the border up to six times before it ends up in a finished automobile.

"You cannot thicken this border without hurting people on both sides of it," Trudeau said. "Any two countries are going to have issues that will be irritants to the relationship. Having a good constructive working relationship allows us to work through those irritants.

Natural Resources Minister Jim Carr echoed Trudeau's sentiment, saying that the tariff hurts people in both countries, including American homebuyers, who will now pay more for wood.

The U.S. and Canada typically enjoy a friendly trading relationship, but things have soured in recent months.

Trump has been railing against Canada's decision to change its policy on pricing domestic milk to cover more dairy ingredients, leading to lower prices for products, including ultra-filtered milk. Trump has called the move "a disgrace" that hurts U.S. producers in dairy states like Wisconsin.
