The political consequences of President Donald Trump’s trade war with Canada are becoming increasingly difficult to ignore across New England. After longtime Republican Senator Susan Collins lost her Maine seat in the November 3, 2026, midterm elections, regional business leaders are renewing calls for Washington to abandon disruptive tariffs and restore predictable trading relationships.

John Gulliver, president of the New England-Canada Business Council, believes the dispute contributed to Collins’ defeat and reflects growing frustration in communities economically connected to Canada.

From Maine’s lobster industry and paper mills to New England’s tourism businesses and energy partnerships, the consequences extend well beyond politics. Business organizations had been warning about these problems for months, but the election result has increased pressure for a resolution that protects workers, consumers and businesses on both sides of the border.

Maine’s Senate Election Delivers a Warning About Trump’s Trade Policies

Democrat Troy Jackson defeated Republican Senator Susan Collins in Maine’s November 3 election, ending her nearly 30-year career in the U.S. Senate. Collins, who had served since 1997 and was seeking a sixth term, struggled to overcome voter dissatisfaction with economic conditions and President Donald Trump’s administration. Jackson, a former logger and president of the Maine Senate, campaigned on affordability, working-class concerns and the argument that Collins had not done enough to challenge Washington’s policies. He received approximately 53% of the vote, securing a significant Democratic victory in a closely watched contest.

The result attracted particular attention because Maine’s economy depends heavily on trade with Canada. Throughout the campaign, tariffs became a recurring point of disagreement, with businesses raising concerns about higher operating costs and disrupted commercial relationships. Although Collins publicly opposed several Canadian tariffs and supported exemptions, Jackson argued that temporary relief could not replace a broader solution. The election involved several major issues, including health care, housing and the cost of living, so tariffs cannot be identified as the sole reason for her defeat. Nevertheless, the result strengthened the argument that trade restrictions were becoming politically costly.

New England Business Council President Calls for an End to the Trade War

John Gulliver, president of the New England-Canada Business Council, delivered a direct message on November 11, 2026: the United States and Canada should end their trade confrontation and return to established dispute-resolution procedures. Speaking to iPolitics from Portland, Maine, Gulliver said American tariffs were unpopular throughout the region and had contributed to Collins’ election defeat. He argued that disagreements involving Canadian dairy policies, softwood lumber and other trade concerns should be addressed through reliable mechanisms rather than escalating import duties. His position reflects the practical concerns of businesses that depend on consistent cross-border arrangements.

The council’s opposition did not suddenly emerge after the election. In August, the organization publicly criticized unpredictable tariffs and retaliatory measures, warning that businesses and workers on both sides of the border would suffer. Its board had also unanimously endorsed renewing the United States-Mexico-Canada Agreement in June. Founded in 1982, the council represents an established network of cross-border commercial interests. Its argument emphasizes stability rather than political allegiance: companies need dependable rules to decide whether to hire workers, purchase equipment or expand operations. Constantly changing trade restrictions make those decisions more expensive and uncertain.

Maine’s $1.3-Billion Canadian Export Market Faces Continued Pressure

Maine’s relationship with Canada is substantial enough that changes in trade policy can affect businesses across the state. According to the Office of the United States Trade Representative, Maine exported approximately US$1.3 billion in goods to Canada in 2025, accounting for 41% of the state’s merchandise exports. Canada was easily Maine’s largest export destination. The relationship also works in the opposite direction, with Maine importing approximately US$4.1 billion in Canadian goods during the same year. Products crossing the border include energy, forest products, seafood and manufacturing inputs.

Smaller businesses are particularly exposed to disruptions because they often have fewer alternative suppliers and less financial flexibility. Federal trade data show that 85% of Maine’s exporting companies in 2024 were small and medium-sized enterprises. The Maine International Trade Center also identifies 94 Canadian-owned businesses supporting approximately 5,350 jobs in Maine. In September 2026, Maine State Chamber of Commerce president Patrick Woodcock described the escalating dispute as a trade war designed to create economic pressure. For a manufacturer relying on Canadian materials or a farmer purchasing specialized equipment, the consequences are immediate business concerns. A tariff can turn an affordable shipment into an unexpected expense, and repeated policy changes make longer-term investments harder to justify.

Collins Secured Tariff Exemptions but Failed to Convince Voters

During her reelection campaign, Collins emphasized her efforts to persuade the Trump administration to remove tariffs on products essential to Maine businesses. In September, she announced exemptions covering road salt and cement, while pulp used by Maine paper manufacturers also received relief. The senator cited specific financial consequences, including an estimated US$10,000 in additional road-salt expenses for the small town of Frenchville. She also described a Maine concrete business that had faced approximately US$150,000 in additional monthly costs. Those examples illustrated why even narrowly targeted tariffs could create significant problems for local employers and municipalities.

Further exemptions followed on October 23, when Trump signed changes removing certain Canadian goods from the 50% tariff list, effective October 30. The affected categories included packaging supplies, agricultural machinery, refrigeration equipment and products important to Maine’s blueberry, potato, apple and seaweed industries. However, the administration also added other products to the tariff list. Jackson argued that these adjustments did not address the wider financial damage caused by the trade confrontation. During an October debate, he challenged Collins’ emphasis on road-salt relief with the memorable observation, “We can’t eat road salt.” The exchange highlighted a political weakness in defending selective exemptions when businesses continued to face broader uncertainty.

Maine’s Lobster Industry Shows How Quickly Tariffs Can Threaten Jobs

Few industries demonstrate the close economic relationship between Maine and Canada more clearly than lobster fishing. During Maine’s important fall fishing season, roughly half of the lobster catch is typically shipped to Canadian processing facilities. These businesses transform live lobster into products such as frozen tails and packaged meat, some of which subsequently return to American markets. The arrangement developed because Canadian processors possess specialized facilities and the capacity to handle large seasonal harvests. Replacing that infrastructure domestically would require substantial investment and time.

The industry faced a serious warning in August 2026 when Canada initially proposed a 25% retaliatory tariff on American seafood. The Maine Lobstermen’s Association argued that the measure could sharply reduce demand from Canadian processors, potentially pushing down prices paid to fishermen during a crucial harvesting period. Canada subsequently removed seafood and fish products from its retaliatory tariff list before the measures took effect on September 8. The decision provided important relief, but the episode exposed the vulnerability of the supply chain. Fishermen, processors, transportation businesses and coastal communities depend on products moving efficiently across the border. A future escalation could threaten those relationships even if lobster remains exempt from the current Canadian countermeasures.

Canadian Tourism Remains Below Earlier Levels Despite Signs of Recovery

New England’s economic exposure extends beyond merchandise trade. Hotels, restaurants, retailers and tourist attractions have traditionally benefited from Canadian visitors, particularly in communities near the Maine-New Brunswick and Maine-Quebec borders. Cross-border shopping trips and family vacations create spending that supports local employment. However, political tensions, economic uncertainty and changing travel preferences have affected these longstanding patterns. Maine Public reported that border crossings into Maine during the first two months of 2026 were approximately 17% lower than during the corresponding period in 2025, continuing a decline that began during Trump’s second presidency.

More recent Canadian statistics show a complicated picture rather than an uninterrupted decline. Statistics Canada reported that Canadian-resident return trips from the United States increased 6.8% in September 2026 compared with September 2025, marking six consecutive months of year-over-year growth. Nevertheless, automobile return trips remained 31.1% below their September 2024 level. That distinction matters because tourism businesses can experience a recovery from a weak year while still attracting substantially fewer visitors than before the dispute intensified. Tariffs are only one influence on travel, alongside exchange rates, fuel costs and political sentiment. The broader concern is that strained relations can discourage tourism and weaken commercial ties that took decades to establish.

Forest Products and Paper Manufacturers Face Supply Chain Disruptions

The forest products industry offers another example of how tariffs can affect businesses on both sides of the border simultaneously. At Woodland Pulp in Baileyville, Maine, Canadian wood fibre has historically accounted for nearly 30% of the mill’s raw material supply. The company temporarily stopped purchasing some New Brunswick hardwood logs and wood chips after earlier American timber tariffs made those imports more expensive. Although Woodland subsequently resumed some purchases, its experience demonstrated how trade restrictions can disrupt established sourcing arrangements. Company representatives also identified weak global markets and high diesel costs as major financial challenges, underscoring that tariffs are not the industry’s only problem.

Woodland-affiliated St. Croix Tissue provides an additional illustration. The company supplies unfinished tissue products to Canadian manufacturers that convert them into consumer goods, but some of those shipments became subject to a 50% Canadian tariff. Meanwhile, Twin Rivers Paper operates interconnected facilities in Edmundston, New Brunswick, and Madawaska, Maine, with pulp travelling across the border for paper production. These operations show why the border cannot easily be separated from the manufacturing process. Canadian government guidance confirms that certain wood and paper products face multiple categories of American duties, depending on their classification. Industry participants must consequently manage higher costs, shifting customer demand and uncertainty about future investments.

New England’s Wider Economy Depends on Canadian Trade and Energy Partnerships

The economic importance of Canada extends across all six New England states. In June 2026, the New England-Canada Business Council noted that Canada ranked as either the largest or second-largest export destination for each state in the region. Vermont illustrates that dependence particularly clearly. Federal American trade figures show that the state exported approximately US$635 million in goods to Canada during 2025, representing 31% of its total merchandise exports. These relationships involve much more than consumer products. Manufacturers, logistics operators, agricultural producers, researchers and professional service firms participate in commercial networks that cross the international boundary.

Energy cooperation is another important part of that relationship. ISO New England reports that the region generally imports electricity through connections with neighbouring power systems, including Quebec and New Brunswick. In October 2026, Nova Scotia and Vermont signed a three-year memorandum of understanding to explore cooperation involving offshore wind, electricity transmission and regional grid integration. The New England-Canada Business Council also scheduled its 34th annual U.S.-Canada Executive Energy Conference for November 12–13 in Boston, bringing together more than 200 industry leaders, policymakers and specialists. These developments demonstrate that regional cooperation continues despite trade tensions. Businesses seeking reliable electricity, competitive energy prices and new infrastructure investments have strong reasons to preserve stable relations with Canadian partners.

Business Leaders Want Trade Disputes Settled Through Established Rules

Rather than relying on another round of tariff retaliation, Gulliver has urged both countries to use the dispute-resolution arrangements available under the Canada-United States-Mexico Agreement, known as CUSMA in Canada and USMCA in the United States. Previous disagreements over Canadian dairy imports demonstrate how such procedures can operate. In 2021, a trade panel found that Canada’s practice of reserving portions of dairy import quotas specifically for processors violated its commitments. Canada subsequently modified the system. A separate panel in 2023 reached a different conclusion, ruling that Canada’s revised allocation measures did not breach the agreement’s relevant obligations.

These decisions demonstrate that trade disagreements can produce different outcomes without requiring an escalating economic confrontation. The larger concern is that the agreement itself now faces uncertainty. During its first formal joint review on July 1, 2026, the United States declined to extend USMCA in its existing form. Under the agreement’s provisions, annual reviews will continue until the three countries agree to an extension or the agreement reaches its scheduled expiration in 2036. The decision did not immediately terminate free trade, but it complicated the planning environment for manufacturers and exporters. Business organizations are therefore seeking more than temporary tariff exemptions: they want a durable framework capable of handling commercial disagreements while preserving long-term confidence.

Democratic Victory Increases Pressure, but Trump Still Controls the Trade Negotiations

The midterm elections have changed Washington’s political balance, with Democrats preparing to assume control of both chambers of Congress in January 2027. Their victory creates opportunities to challenge Trump’s tariffs through legislation, oversight hearings and negotiations. Opposition is not confined to Democrats. On November 10, former Maine governor Paul LePage, a Republican expected to represent the state’s 2nd Congressional District after completion of ranked-choice tabulation, said reversing Canadian tariffs would be a priority. He specifically highlighted wood products and the need to restore productive relations with Canada, reinforcing the argument that trade restrictions have become politically difficult even for some Republicans.

Nevertheless, the election does not automatically remove existing tariffs. Trump retains presidential veto authority, and overturning a veto requires two-thirds support in both congressional chambers. A February 2026 Supreme Court decision invalidated tariffs imposed under emergency economic powers legislation but did not eliminate tariffs authorized under other laws, including Section 232 measures. Canadian Prime Minister Mark Carney acknowledged this reality on November 10, emphasizing that the Trump administration remains the central decision-maker in bilateral trade negotiations. For New England businesses, Collins’ defeat represents increased political pressure rather than an immediate economic breakthrough. The practical outcome will depend on whether that pressure leads to meaningful negotiations, fewer trade restrictions and more predictable rules for the companies and communities that rely on cooperation across the border.
