Several U.S. presidents have imposed tariffs on Canadian lumber as part of a decades-long trade dispute between the United States and Canada, primarily over softwood lumber. This conflict, often referred to as the “softwood lumber dispute,” stems from U.S. claims that Canadian lumber is unfairly subsidized by government-set stumpage fees, giving Canadian producers an advantage over American ones. Below is a list of presidents who have overseen the imposition of tariffs on Canadian lumber, based on historical actions and trade policies:
-
Ronald Reagan (1981–1989)
-
The modern softwood lumber dispute began in the 1980s under Reagan. In 1986, during “Lumber II,” the U.S. Commerce Department, responding to a petition from the U.S. lumber industry, found Canadian subsidies countervailable and set a preliminary duty of 15%. Before it was fully imposed, the U.S. and Canada signed a Memorandum of Understanding (MOU) that included a Canadian export tax on lumber, effectively acting as a tariff mechanism. This set a precedent for future disputes.

-
George H.W. Bush (1989–1993)
-
The MOU from Reagan’s era continued into Bush’s presidency. However, in 1991, Canada withdrew from the agreement, prompting the U.S. to impose a 6.51% countervailing duty in 1992 during “Lumber III.” This tariff was later adjusted, but it marked continued action under Bush to address U.S. industry complaints.

-
George W. Bush (2001–2009)
-
In 2002, the Commerce Department under George W. Bush imposed a 27% tariff (combining countervailing and anti-dumping duties) on Canadian softwood lumber, following a determination that Canadian subsidies and dumping harmed U.S. producers. This led to years of litigation, culminating in the 2006 Softwood Lumber Agreement (SLA), which replaced tariffs with a system of export taxes and quotas managed by Canada. The SLA lasted until 2015.
-
-
Donald Trump (2017–2021, 2025–present)
-
During his first term, Trump escalated the dispute in 2017 by imposing tariffs averaging 20% (ranging from 3% to 24.12%) on Canadian lumber imports, announced by Commerce Secretary Wilbur Ross. This followed the expiration of the 2006 SLA in 2015 and failed negotiations for a new deal. In his second term, beginning in 2025, Trump has proposed an additional 25% tariff on all Canadian goods, including lumber, on top of existing duties (which had risen to 14.54% by 2024), though this was delayed for one month as of February 2025 for further negotiations. He also initiated a new trade investigation in March 2025 that could lead to further tariffs.
-
-
Joe Biden (2021–2025)
-
Under Biden, the Commerce Department raised tariffs on Canadian softwood lumber from 8.05% to 14.54% in August 2024, following its annual administrative review of existing duties. While this was not a new tariff but an adjustment of rates set during prior administrations, it reflects continued enforcement of trade remedies against Canadian lumber during Biden’s tenure.

Context and Notes:
-
Earlier Presidents: The dispute’s roots predate Reagan, with tensions emerging in the 1960s and 1970s, but specific tariff actions are less documented under presidents like Lyndon B. Johnson or Richard Nixon. The formal cycle of tariffs began in the 1980s.
-
Other Presidents: Presidents like Bill Clinton (1993–2001) and Barack Obama (2009–2017) oversaw periods of negotiation or truces (e.g., the 1996 Softwood Lumber Agreement under Clinton and attempts at a permanent solution under Obama), but no major new tariffs were imposed during their terms. Duties persisted or were contested through legal channels instead.
-
Mechanism: Tariffs are typically imposed by the Commerce Department or the U.S. International Trade Commission (USITC) under trade remedy laws, not directly by presidential decree, though presidents influence trade policy direction.
This list focuses on presidents who directly oversaw the imposition or significant escalation of tariffs. The softwood lumber dispute remains unresolved, with tariffs fluctuating based on administrative reviews, legal challenges, and bilateral agreements.
