Looks like it's time to blame Canada.
After repeated campaign promises to "get tough on trade," President Donald Trump just moved to slap a roughly 20 percent tariff on softwood lumber entering the United States from Canada, reviving a long-smoldering trade dispute between the U.S. and its second-largest trading partner.
The move follows complaints from U.S. dairy farmers about a recent decision by the Canadian dairy industry to change pricing categories on certain milk products. The action has had the effect of cutting prices Canadian cheese makers pay for dairy ingredients.
