While most of U.S.-Canada trade flows smoothly, there are occasionally bilateral trade disputes, particularly in the agricultural and cultural fields. Usually these issues are resolved through bilateral consultative forums or referral to World Trade Organization (WTO) or NAFTA dispute resolution. In May 1999, the U.S. and Canadian governments negotiated an agreement on magazines that provides increased access for the U.S. publishing industry to the Canadian market. The United States and Canada also have resolved several major issues involving fisheries. By common agreement, the two countries submitted a Gulf of Maine boundary dispute to the International Court of Justice in 1981; both accepted the court's October 12, 1984 ruling which demarcated the territorial sea boundary. A current issue between the United States and Canada is the ongoing softwood lumber dispute, as the U.S. alleges that Canada unfairly subsidizes its forestry industry.
