Ontario Premier Doug Ford is preparing a renewed diplomatic push in Washington after the November 3, 2026, U.S. midterm elections handed Democrats control of both chambers of Congress, creating a potential opening in Canada’s ongoing trade dispute with President Donald Trump.
Ford plans to send provincial ministers to meet newly elected American lawmakers and governors, hoping to rebuild relationships and challenge tariffs threatening Ontario’s manufacturing economy.
However, the political shift comes with an uncomfortable deadline. Trump has threatened to increase tariffs on Canadian vehicles, automotive parts and steel to 50% on January 1, 2027.
For Ontario’s automakers, suppliers and manufacturing communities, the stakes extend far beyond political negotiations. Thousands of jobs, billions in cross-border trade and future investment decisions depend on whether the two countries can find a more stable economic relationship.
Ford Sees an Opportunity After Democrats Win Congress
The November 3 midterm elections delivered a significant political shift in Washington, with Democrats securing control of the House of Representatives and Senate. Ontario Premier Doug Ford welcomed the outcome enthusiastically, telling reporters the following day that he had been doing cartwheels as the results arrived. Behind the colourful reaction was a serious economic calculation. Ford believes American voters delivered a message about affordability, energy costs and the economic consequences of Trump’s policies, including tariffs. For Ontario, that potentially creates an opportunity to make its case to American politicians who may be more receptive to concerns about trade barriers.
Ford’s excitement was tempered by a warning that the trade conflict remains far from resolved. He acknowledged that Trump still controls important aspects of American trade policy, meaning a Democratic congressional majority does not automatically eliminate tariffs. The distinction matters enormously to Ontario businesses. A supplier deciding whether to expand production cannot rely on favourable election results alone. Companies need predictable trade rules, dependable customers and confidence that vehicles and components can cross the border without facing sudden additional costs. Ford’s challenge is translating a changing political environment into meaningful economic protection.
Ontario Ministers Will Target Newly Elected American Officials
Ford has instructed members of his cabinet to prepare outreach to newly elected U.S. representatives, senators and governors once they assume office. The goal is to establish relationships with decision-makers who could influence Washington’s approach to Canada. Rather than relying exclusively on federal negotiations between Ottawa and the White House, Ontario wants to communicate directly with American political leaders about the damage caused by the trade dispute. Ford has emphasized the importance of governors, recognizing that state leaders have economic interests closely connected to Canadian trade. The approach could be particularly relevant in manufacturing states where businesses depend on Canadian customers, suppliers and production facilities.
The timing creates a challenge. The new Congress is scheduled to begin its term on January 3, 2027, two days after Trump’s threatened tariff increases are supposed to take effect. Ford has indicated that ministers will travel after newly elected officials are sworn in, although a detailed itinerary and confirmed meetings have not been publicly established. That means Ontario’s planned outreach may be more effective in challenging or reversing measures than preventing their initial implementation. Nevertheless, establishing connections early could help provincial officials communicate concerns directly to congressional offices, trade committees and state governments rather than waiting for formal diplomatic negotiations to produce results.
Trump’s 50% Auto Tariff Threat Remains a Major Risk
Despite the election results, Trump’s threatened January 1 tariff increase remains a serious concern for Ontario’s automotive industry. On August 24, the president announced plans to raise U.S. tariffs on Canadian cars, trucks, automotive parts and steel to 50% beginning in 2027. The announcement followed the collapse of trade negotiations that had considered reducing certain existing duties. Before those talks broke down, a proposed arrangement reportedly would have lowered tariffs on Canadian cars and light trucks from 25% to 15%. Disagreements over the treatment of larger commercial trucks were among the issues that prevented a deal. The threatened increase therefore represents a substantial deterioration from the relief manufacturers had hoped to secure.
The existing tariff structure is already complicated. Under U.S. rules introduced in 2025, qualifying vehicles covered by the Canada-U.S.-Mexico Agreement can receive special treatment that limits the 25% vehicle tariff to their non-U.S. content. Qualifying automotive parts also benefit from specific exemptions. Trump’s proposed 50% increase raises questions about how those protections would operate if the threat is implemented. An announced tariff threat is not the same as a completed customs measure, and the eventual treatment of individual products will depend on the final rules. Even without immediate implementation, uncertainty can discourage investment, complicate pricing decisions and make long-term production planning more difficult.
Nearly 100,000 Ontario Auto Jobs Are Exposed to Trade Uncertainty
Ontario’s automotive industry represents far more than a collection of assembly plants. The province’s vehicle and parts manufacturing sector employs roughly 100,000 people, with additional employment supported through transportation, engineering, equipment manufacturing and other services. Federal economic development data show that Ontario exported approximately $60 billion worth of automotive products to the United States in 2025, representing about 96% of its automotive exports. That concentration illustrates why American trade policy has such an immediate impact on the province. When access to the U.S. market becomes more expensive or unpredictable, Ontario manufacturers have limited opportunities to replace that demand quickly.
Statistics Canada has documented just how dependent vehicle production is on American buyers. Its analysis of 2024 economic activity found that U.S. demand accounted for approximately 76.4% of payroll jobs in Canada’s automobile and light-duty motor vehicle manufacturing industry. The consequences can extend into communities where a major factory supports surrounding businesses. A reduction in production can affect parts deliveries, trucking contracts and spending at nearby restaurants and shops. For workers in Windsor, Oshawa, Oakville and other manufacturing centres, trade uncertainty is not simply an economic indicator. It can influence household budgets, overtime opportunities and decisions about whether to remain in a community built around automotive employment.
North America’s Integrated Auto Supply Chain Makes Tariffs Costly
The automotive industries of Canada, the United States and Mexico have developed an unusually interconnected manufacturing system. According to the Canadian Vehicle Manufacturers’ Association, components can cross North American borders as many as eight times before reaching final assembly. An engine component might be produced in one country, machined in another and returned for installation in a completed vehicle. This arrangement allows manufacturers to specialize, coordinate production and draw on suppliers throughout the continent. However, it also means that trade restrictions can affect several businesses involved in producing a single vehicle, rather than simply increasing the cost of a finished Canadian-made car entering the United States.
The Windsor-Detroit corridor provides a particularly visible example of this integration. Transport Canada recorded approximately 2.64 million two-way truck movements at the Ambassador Bridge in 2024, making it the country’s busiest truck border crossing. Automotive shipments form an important part of the economic activity connecting the region. For manufacturers, maintaining predictable border access helps protect delivery schedules and production efficiency. For American companies, Canadian suppliers are often part of their own manufacturing operations rather than distant competitors. Ford’s diplomatic argument can therefore emphasize shared economic consequences. Tariffs intended to encourage American production may also increase costs for businesses that depend on components and materials purchased from Canada.
Democratic Control Could Challenge Tariffs but Cannot Automatically Remove Them
The incoming Democratic majority could create significant political pressure on Trump’s trade policies. Oregon Senator Ron Wyden, who is expected to chair the Senate Finance Committee, has identified efforts to repeal tariffs on Canadian goods as an important priority. Following the midterms, Democratic lawmakers began discussing legislation that could challenge existing duties and limit the president’s ability to impose additional tariffs without greater congressional involvement. Congressional committees could also hold hearings, question administration officials and examine whether trade restrictions are delivering the economic benefits promised to American voters. These developments offer Ontario new opportunities to present evidence about manufacturing costs, investment uncertainty and the importance of Canadian-American supply chains.
However, the constitutional and political obstacles remain considerable. Trump can veto legislation passed by Congress, and overriding a presidential veto requires a two-thirds majority in both chambers. Democrats would therefore need substantial Republican support to force through legislation opposed by the White House. Moreover, some American Democrats support protectionist trade measures in particular industries, meaning opposition to Trump does not necessarily translate into support for unrestricted trade with Canada. Congressional pressure could influence negotiations without producing immediate legal changes. For Ontario, the most realistic benefit may initially be stronger scrutiny of tariffs, additional political allies and increased pressure for negotiated relief rather than a rapid elimination of every trade barrier.
American Manufacturing States Have Reasons to Support Ontario
Ford’s outreach strategy could find an audience in states where economic ties with Canada are particularly important. Michigan, for example, counts Canada as its largest international goods-export market, according to the Office of the United States Trade Representative. The relationship extends across automotive manufacturing, machinery and other industries that depend on cross-border customers. Research published by Oxford Economics in September 2026 also identified significant American exposure to Trump’s proposed 50% automotive tariffs. Relative to the national average, jobs in Kentucky were estimated to be 3.7 times more exposed to Canadian automotive supply chains, followed by Michigan at 3.5 times and Indiana at 3.2 times. These figures measure exposure, not predicted job losses.
Such findings provide Ontario with arguments that go beyond appeals for Canadian economic protection. Provincial officials can demonstrate how tariffs potentially affect American businesses, employment and investment. A Michigan parts manufacturer selling components to an Ontario assembly plant has an obvious interest in maintaining competitive trade conditions. Governors and congressional representatives from manufacturing states may therefore recognize that restricting Canadian production can also create difficulties for local employers. However, economic connections do not guarantee political agreement. Some American officials may prioritize domestic production even when tariffs generate additional costs. Ford’s challenge will be persuading lawmakers that strengthening integrated North American manufacturing better serves their constituents than attempting to separate industries that have operated together for decades.
Ottawa Is Maintaining Its Trade Strategy Despite the Political Shift
While Ford welcomed the Democratic victories, Prime Minister Mark Carney’s government has adopted a more measured public response. Canada-U.S. Trade Minister Dominic LeBlanc said on November 4 that the election results would not change Ottawa’s efforts to diversify trade and strengthen the Canadian economy. He emphasized that Canada’s immediate responsibilities remain unchanged regardless of which party controls Congress. LeBlanc also indicated that recent discussions with American officials had been productive. This approach reflects an important distinction between Ontario’s planned relationship-building campaign and Ottawa’s formal negotiations with the Trump administration. Provincial officials can advocate for their industries, but the federal government remains responsible for negotiating Canada’s international trade arrangements.
By November 6, Carney had welcomed potential congressional efforts to restore freer trade between Canada and the United States. He acknowledged that reducing trade barriers could benefit workers and families in both countries, while confirming that he had not yet discussed the proposed tariff legislation directly with Democratic lawmakers. His government was also pursuing negotiations with Washington following the breakdown of discussions in August. The two Canadian approaches are not necessarily contradictory. Ford can cultivate political allies among governors and legislators while Ottawa continues working with the administration responsible for implementing tariff measures. Both channels could become useful if American political pressure encourages a compromise, although neither guarantees an agreement.
Ford and Carney Are Also Investing Billions to Protect Ontario Industries
Diplomacy is only one part of Ontario’s response to the trade conflict. On October 21, Ford and Carney announced a combined $8.7 billion action plan targeting steel, automotive manufacturing and critical mineral development. The initiative includes an additional $2.5 billion over two years for major automotive capital projects, with Ottawa contributing $1.5 billion and Ontario providing $1 billion. The funding is intended to help automakers modernize equipment, improve production lines and prepare for increasingly advanced and electrified vehicles. The governments also announced a joint automotive task force to coordinate implementation and strengthen the industry’s competitiveness. These measures reflect an effort to protect industrial capacity even while uncertainty over American market access persists.
The broader package also includes a $5.22 billion joint steel action fund, combining federal and provincial commitments over five years. Steel manufacturing is closely connected to automotive production, making both sectors vulnerable to changes in trade policy. Ontario’s strategy therefore involves protecting established manufacturing operations while encouraging investment in newer technologies and domestic supply chains. However, public funding cannot fully replace access to the enormous American market. Manufacturers still need competitive production costs, long-term customer relationships and sufficient demand to justify major investments. The success of these initiatives will depend partly on whether governments can attract private investment and help businesses adapt rather than simply offsetting the immediate financial consequences of tariffs.
The Next Trade Test Extends Beyond January’s Tariff Deadline
Ontario’s diplomatic challenge also intersects with uncertainty surrounding the Canada-U.S.-Mexico Agreement, known as CUSMA in Canada and USMCA in the United States. During the agreement’s July 1, 2026, joint review, the United States declined to renew the existing arrangement in its current form. However, that decision did not immediately terminate the agreement. Under its provisions, CUSMA remains in force through 2036 unless changed or ended earlier through applicable procedures, with annual reviews required until the three countries agree on an extension or the existing term expires. The U.S. Trade Representative has already opened consultations for the 2027 review, with public comments due January 12. Incoming American lawmakers could consequently have opportunities to influence a wider debate about North American trade rules.
For Ontario, the immediate priorities are more urgent: preventing or reducing the threatened January tariff increase, protecting existing manufacturing operations and restoring confidence in cross-border investment. Ford’s planned Washington outreach could help build support for those objectives, especially if American lawmakers become increasingly concerned about the economic consequences of tariffs. Yet meaningful progress will have to be measured through policy decisions rather than political statements. A negotiated reduction in duties, clearer rules for automotive components or stronger protections for existing supply chains would offer businesses something tangible. Until then, Ontario’s manufacturers face an uncomfortable reality. The election has created new political possibilities, but the economic uncertainty confronting workers and employers has not disappeared.
