Canada’s shipments of softwood lumber south of the border are injuring American producers, the U.S. International Trade Commission has ruled in its final determination. The ITC’s final vote, in a 4-0 decision on Thursday in favour of the United States, comes amid deadlocked talks to overhaul the North American free-trade agreement, adding one more strain to the already tense relationship between Ottawa and the Trump administration. “The ITC is down to four commissioners, with two more to complete the panel nominated but not yet confirmed,” Resolute Forest Products Inc. spokesman Seth Kursman said in a statement. “This vote is designed to apply more political pressure on Canada to settle on adverse terms. We won’t do that.”… “The U.S. Lumber Coalition fully supports the enforcement of America’s trade laws”… coalition co-chairman Jason Brochu said in a release on Thursday.
