Canada opens WTO case against United States over lumber duties

OTTAWA, Nov 28 (Reuters) - Canada on Tuesday formally opened a case against the United States at the World Trade Organization over a recent Commerce Department decision to impose duties on Canadian lumber exports, the foreign ministry said.

A ministry statement said Canada would forcefully defend the lumber industry against the "unfair, unwarranted and deeply troubling" decision. Earlier this month Canada launched a NAFTA trade challenge against the duties.
