A growing legal battle over President Donald Trump’s tariffs on Canadian goods is heading toward a crucial courtroom hearing that could reshape the future of U.S.–Canada trade. On January 20, 2027, the U.S. Court of International Trade is scheduled to hear arguments challenging the administration’s decision to impose additional 50% duties on selected Canadian imports under a nearly century-old trade law.

The lawsuit, brought by American food importer Gellert Global Group, raises questions about presidential authority, congressional oversight and the economic consequences of escalating tariffs. With billions of dollars in cross-border trade affected, the dispute reaches beyond Washington and Ottawa. Canadian exporters, American businesses and consumers on both sides of the border have a significant interest in how the courts interpret the administration’s powers.

The January Hearing Could Determine the Fate of the Tariffs

The January 20 hearing marks an important stage in a legal dispute that began on October 20, 2026, when Gellert Global Group filed its complaint in the U.S. Court of International Trade in New York. The case challenges the administration’s use of Section 338 of the Tariff Act of 1930. A three-judge panel will consider whether the federal government acted within its statutory authority. The company is seeking a declaration that the duties are unlawful, an order preventing further collection and refunds with interest for tariffs already paid.

The legal proceedings are moving on an expedited schedule, reflecting the continuing financial consequences for affected businesses. Gellert has also requested permission to represent a broader class of American importers that have paid the disputed duties, although that proposed class has not yet been certified. The January hearing will allow the judges to examine arguments from both sides, but it does not guarantee an immediate decision. Even if the court rules against the administration, further appeals could extend the dispute and leave businesses waiting for financial relief.

The 50% Tariffs Target Billions in Canadian Exports

The tariffs are substantial, but they do not apply to every Canadian product entering the United States. The administration introduced three presidential proclamations on July 20, 2026, targeting selected Canadian goods over disputes involving alcoholic beverages, dairy and motor vehicles. The measures ultimately took effect on August 22. According to Canada’s Department of Finance, the original tariffs affected approximately C$27.6 billion in Canadian exports, equivalent to roughly US$20 billion. Products targeted have included sporting equipment, furniture, clothing, food products, electronics and industrial materials.

The scope has continued changing since the original announcement. In September, Washington expanded some product lists while removing other goods. A further modification announced on October 23 took effect on October 30, removing 22 tariff classifications while adding another 100. These changes demonstrate why the precise classification of an imported product matters. Unlike several other U.S. tariff measures, the Section 338 duties do not provide a general exemption for goods qualifying under the Canada–United States–Mexico Agreement, known as CUSMA in Canada and USMCA in the United States.

Trump Revived a Depression-Era Law That Had Never Been Used This Way

The legal foundation for the tariffs dates back to the Smoot-Hawley Tariff Act of 1930, legislation associated with one of the most turbulent periods in international trade history. Section 338 permits additional duties of up to 50% when the president determines that another country discriminates against American commerce. The provision also allows certain import restrictions under specified conditions. Although it has remained part of American law for almost a century, the Trump administration became the first to expressly invoke it to impose tariffs in July 2026.

The White House argues that Canada’s treatment of American products justified the action. U.S. Trade Representative Jamieson Greer pointed to restrictions on American alcoholic beverages in Canadian provinces, differences in dairy market access and Canadian measures affecting U.S. automobiles. Washington maintains that these policies disadvantage American producers compared with competitors from other countries. Canadian officials reject that interpretation, arguing that restrictions on American alcohol and vehicles were responses to earlier U.S. tariffs. Ottawa also maintains that its dairy import policies comply with CUSMA. Determining whether the alleged discrimination satisfies Section 338 is a central issue in the case.

A Family-Run American Importer Is Leading the Challenge

Gellert Global Group is not a Canadian government agency or an international trade organization. It is a third-generation American food importing and distribution business based in New Jersey. According to its court complaint, the company imported approximately US$71 million worth of Canadian cheese during 2025. Those imports had historically benefited from duty-free treatment under the North American trade agreement. Gellert estimates that the new Section 338 tariffs could cost it approximately US$40 million annually, placing significant pressure on its operating margins, investment plans and relationships with customers.

One of the most revealing examples involves a supplier that purchases milk from dairy farmers in upstate New York, processes it into brie in Canada and then ships the finished cheese back to American buyers. A tariff on that cheese therefore affects a commercial relationship supporting farmers and businesses in both countries. Gellert also says Canadian retaliation has affected American-made cheeses sold through its Canadian operations. The dispute illustrates how tariffs can create unexpected consequences in integrated supply chains, where an imported product may depend on raw materials, workers and customers located on both sides of the border.

The Lawsuit Questions Whether Later Trade Laws Replaced Section 338

A central argument in Gellert’s lawsuit concerns the relationship between two pieces of American legislation passed more than four decades apart. The company contends that Section 301 of the Trade Act of 1974 superseded, or at least substantially restricted, the tariff powers contained in Section 338. The newer legislation established procedures for investigating unfair foreign trade practices, consulting with trading partners and providing opportunities for public participation. Gellert’s lawyers argue that these safeguards cannot be avoided simply by invoking an older law that previous administrations had never used to impose tariffs.

The administration’s position rests on the fact that Section 338 remains in federal law and expressly authorizes additional duties of up to 50% under specified conditions. Whether Congress intended subsequent legislation to restrict that authority is a question the judges must consider. Gellert also argues that imposing the same maximum tariff rate across three different trade disputes fails to demonstrate how the duties specifically offset the alleged disadvantages to American commerce. The case therefore raises two connected issues: whether the president used a valid legal authority and whether the measures themselves satisfy the limits of that authority.

Canadian Cheese Tariffs Face a Separate 30-Day Legal Challenge

One of the lawsuit’s most specific allegations involves the timing of tariff collection. On September 8, 2026, the administration revised its product lists to include additional Canadian cheeses, with the new duties taking effect on September 15. That left only seven days between the announcement and implementation. Section 338 provides for duties to be collected 30 days after the relevant proclamation. Gellert argues that the administration failed to respect this statutory waiting period and improperly collected additional tariffs from importers whose products had only recently been added.

The company also questions why certain Canadian cheeses were placed under tariff measures addressing entirely different industries. According to its complaint, the administration added broad categories of cheese to a list associated with Canadian restrictions on American alcohol, while another cheese classification was included under the motor vehicle proclamation. The original proclamation dealing directly with Canadian dairy policy did not itself cover cheese. Gellert contends that these inconsistencies weaken the government’s justification for selecting the affected products. The court must determine whether the timing and product classifications comply with Section 338 before any legal consequences can be established.

Canada Responded With Billions in Retaliatory Tariffs

Canada introduced its own tariff measures after negotiations with Washington failed to prevent the new U.S. duties. On August 25, 2026, the federal government announced plans to match the American measures on a dollar-for-dollar basis. The Canadian counter-tariffs took effect on September 8, covering approximately C$27.6 billion in imports from the United States. Rather than applying one uniform rate, Ottawa imposed duties of 15%, 25% or 50%, depending on the products involved. Targeted sectors included steel, aluminum, dairy, household appliances, agricultural equipment, pulp and paper, plastics and electronics.

The retaliation expanded the economic effects of the disagreement. Canadian businesses importing American equipment or materials faced additional costs, while U.S. exporters encountered new barriers to their largest neighbouring market. Ottawa also announced a C$7.5 billion package of new and expanded assistance measures to support businesses and workers affected by trade disruptions. Meanwhile, Washington separately introduced import bans on selected Canadian products, affecting nearly US$1 billion in annual trade. These developments mean that the January court hearing concerns only part of a much larger dispute. A ruling against the U.S. tariffs would not automatically remove Canada’s countermeasures or settle the broader disagreements between the two governments.

The Economic Consequences Extend Far Beyond Individual Importers

Tariffs are collected from importing businesses, but their economic effects rarely stop at the border. A hypothetical shipment of Canadian cheese valued at US$100,000 would face US$50,000 in additional Section 338 duties before accounting for other applicable charges. Importers may respond by increasing prices, negotiating lower supplier costs or absorbing part of the expense themselves. For companies operating on narrow margins, these decisions can affect staffing, inventory and long-term investment. Gellert’s complaint describes precisely these concerns, including pressure on working capital, delayed investment and the possibility of losing established customers.

The broader economic outlook is also concerning. In an October 20 assessment, Canada’s Parliamentary Budget Officer estimated that recent trade actions increased the trade-weighted average effective U.S. tariff rate on Canadian imports from 5.3% to 7.7%. Under a scenario in which the wider tariff measures remain permanent, the office projected that Canada’s real GDP could be 1.4% lower after five years than under a pre-tariff baseline. Employment could also fall by as many as 185,000 jobs relative to that baseline. Those projections concern the combined trade restrictions introduced since 2025, not Section 338 alone, and actual outcomes will depend on how businesses adapt.

Previous Court Rulings Have Already Limited Trump’s Tariff Powers

The January hearing comes after other significant legal setbacks for the administration’s trade strategy. On February 20, 2026, the U.S. Supreme Court ruled that the International Emergency Economic Powers Act did not authorize the president to impose tariffs. The decision invalidated a central legal foundation for tariffs introduced during Trump’s second term. Another challenge followed when the U.S. Court of International Trade struck down tariffs imposed under Section 122 of the Trade Act of 1974 on May 7. That ruling remains subject to appellate proceedings.

Those decisions establish an important legal backdrop, but they do not automatically determine the outcome of Gellert’s case. Section 338 differs from the previously challenged legislation because it explicitly authorizes tariffs of up to 50%, provided its statutory requirements are satisfied. The administration can therefore argue that Congress granted specific powers that were absent from the emergency law considered by the Supreme Court. Even an eventual ruling invalidating the disputed Section 338 duties would not necessarily eliminate separate tariffs imposed under Section 232 or Section 301. The distinction matters for Canadian industries already dealing with multiple layers of trade restrictions.

What Happens After the January 20 Court Hearing?

The court has established a detailed schedule leading up to oral arguments. Briefs from outside parties supporting Gellert’s motion are due November 13, 2026, while the administration’s response is scheduled for December 11. Supporting submissions on the government’s side are due December 23, followed by Gellert’s reply on January 11, 2027. The remaining joint case materials and the government’s answer to the complaint are due January 15. Oral arguments will follow five days later. The court has not established a deadline for delivering its final decision.

Several outcomes remain possible. Judges could uphold the administration’s interpretation of Section 338, invalidate the challenged measures or issue a narrower ruling addressing particular legal defects. If the importer succeeds, questions about refunds, the scope of relief and potential appeals could require additional proceedings. Meanwhile, affected Canadian exporters and American importers must continue navigating the tariffs and restrictions currently in force. Beyond the immediate financial stakes, the case could influence how future presidents exercise trade powers delegated by Congress. The January hearing will test not only the legality of these particular tariffs but also the limits of presidential authority in one of the world’s most economically integrated trading relationships.
