The softwood lumber dispute refers to a long-standing trade conflict between Canada and the United States over the export of softwood lumber, primarily used in construction. This dispute stems from allegations by U.S. companies that Canada subsidizes its lumber industry, allowing Canadian companies to sell lumber at lower prices than their U.S. counterparts, leading to accusations of unfair trade practices. The complexities of this issue are intertwined with various trade agreements and negotiations that shape Canada-U.S. relations.
