At a space-industry conference in Gatineau on October 20, U.S. Ambassador Pete Hoekstra offered a striking description of the increasingly tense Canada-U.S. relationship: Washington does not consider itself to be in a trade war with Canada. That argument comes despite 50% U.S. tariffs imposed in August on roughly C$27.6 billion worth of targeted Canadian goods and Canada’s retaliatory measures of the same value.
Hoekstra’s broader message was that the relationship remains too economically and strategically important to abandon. He urged Canada to keep U.S. partnerships at the centre of its space and defence planning, even as Ottawa diversifies toward Europe and reduces dependence on American suppliers such as SpaceX. The tension between those messages—economic pressure on one side, calls for deeper cooperation on the other—now defines a growing part of the bilateral relationship.
Hoekstra Says the Relationship Is Bruised, Not Broken
Hoekstra’s central argument was less about denying that tariffs exist than about rejecting the label Canada has attached to the dispute. Speaking during a fireside chat at SpaceBound 2026, he said the United States views the two countries as negotiating tariff levels rather than fighting a trade war. He also argued that the relationship has not been “ruptured,” even if many Canadians see the situation differently. The distinction matters politically. Prime Minister Mark Carney has repeatedly described the dispute as a trade war, while the Trump administration has framed its measures as an effort to correct what it considers discriminatory Canadian trade practices.
The ambassador also pointed to the amount of commerce still moving normally. He estimated that roughly 80% to 85% of products continue crossing the border tariff-free and emphasized the depth of a commercial relationship in which more than US$2.5 billion in goods and services typically crosses the border each day. That helps explain Washington’s position: the tariffs are serious, but they sit inside a much larger system of trade, investment, defence and industrial integration that continues to function. For companies actually caught in the tariff lines, however, that distinction can feel academic. A business facing a 50% border charge experiences the dispute very differently from one whose products still enter duty-free.
The 50% Tariffs Are Not Symbolic
The latest tariff fight is unusually significant because the United States used Section 338 of the Tariff Act of 1930, a rarely invoked authority that allows duties of up to 50% in response to alleged discrimination against American commerce. Congressional researchers said President Trump’s July 2026 proclamations marked the first time a president had expressly cited Section 338 to impose tariffs. After a short delay, the new duties took effect on August 22. Canada says they covered about C$27.6 billion in Canadian goods, or roughly US$20 billion at the time, and unlike many earlier tariff measures, covered products do not receive an exemption simply because they comply with CUSMA.
The affected categories have included products such as plastics, furniture, information and communications technology equipment, electronics, paper goods, industrial machinery, wood products, textiles, apparel and sporting goods. The 50% rate therefore does not apply to everything Canada sells to the United States, but it is far from a token measure. The Parliamentary Budget Office estimated this month that trade actions introduced since June pushed the trade-weighted average effective U.S. tariff rate on Canadian imports from 5.3% to 7.7%. That broader average helps put the headline rate in perspective: most trade is not taxed at 50%, but the companies inside targeted sectors can face a severe competitive shock almost overnight.
Canada Answered With Its Own Tariff Package
Ottawa did not treat the August measures as a routine negotiating adjustment. After the bilateral talks broke down, Canada announced that it would match the new U.S. tariffs dollar for dollar and, where applicable, rate for rate. The countermeasures took effect September 8 on C$27.6 billion worth of U.S. imports, using tariff rates of 15%, 25% and 50%. The product list concentrated on sectors including steel, dairy, appliances, agricultural equipment, pulp and paper, plastics and electronics—areas the federal government said were closely connected to industries already affected by American trade actions.
The government also announced C$7.5 billion in new and enhanced support for workers and businesses, on top of nearly C$25 billion in assistance it said had already been provided since U.S. tariffs began reshaping the relationship. Carney said Canada suspended negotiations rather than accept proposed terms his government considered unfair and economically damaging. That sequence is important when assessing Hoekstra’s description of events. Washington may call the confrontation tariff negotiation, but Ottawa has formally retaliated, businesses on both sides are paying new border costs, and the PBO now describes the relationship as increasingly defined by tariffs and sector-specific restrictions. Whatever label governments prefer, companies are making decisions in a materially less open North American market.
A Massive Trading Relationship Still Runs Underneath the Fight
Hoekstra’s strongest case against the “rupture” narrative is the sheer scale of the economic relationship. U.S. Trade Representative data show that U.S. goods and services trade with Canada totalled an estimated US$872.3 billion in 2025, including US$715.5 billion in goods. Canadian government material has long put daily two-way goods and services trade at more than US$2.5 billion. Before the newest Section 338 measures, Ottawa estimated that about 85% of Canadian exports to the United States entered tariff-free. Hoekstra’s October estimate of 80% to 85% suggests he still sees duty-free commerce as the dominant part of the relationship after the latest escalation.
That does not mean the pain is evenly distributed. The PBO says the largest sectoral effects have been concentrated in steel, aluminum, forestry and softwood lumber, automotive manufacturing, plastics, electrical equipment, furniture and wood products. These are precisely the kinds of industries where cross-border supply chains can turn a tariff into a production problem rather than a simple tax at the border. More than 70% of Canadian goods exported to the United States are used in the production of other goods, according to federal briefing material. A tariff on an intermediate input can therefore move through factories, suppliers and prices on both sides of the border, even while the majority of trade remains formally tariff-free.
Space Cooperation Gives Hoekstra a Powerful Example
Space is one of the clearest examples of how deeply the two countries remain connected despite the trade dispute. In April, Canadian astronaut Jeremy Hansen flew around the Moon on NASA’s Artemis II mission, becoming the first Canadian to travel on a lunar mission. Six months later, Canadian astronaut Joshua Kutryk launched to the International Space Station aboard a SpaceX Crew Dragon on NASA’s Crew-13 mission. Kutryk became the first Canadian to fly under NASA’s Commercial Crew Program and is scheduled to spend about six months aboard the station. Those two missions gave Hoekstra a vivid talking point: two Canadian astronauts reached space on American launch systems in the same year.
The cooperation extends beyond individual astronauts. Canada remains involved in lunar exploration through robotics, including the Canadarm3 program associated with the Gateway lunar outpost, while Canadian researchers and companies participate in U.S.-led science, communications and exploration programs. For the Canadian space sector, access to American missions provides flight opportunities, customers and technical partnerships that would be difficult to replace quickly. That is why Hoekstra’s appeal was about more than symbolism. He was effectively warning that choices made in trade, procurement and national-security policy can spill into a sector where the two countries have spent decades building systems designed to work together.
The Dispute Over SpaceX Is Really About Dependency
The most pointed part of Hoekstra’s space message concerned SpaceX. Carney said in a September interview that Canada would diversify away from Starlink, arguing that critical communications and defence systems should not depend too heavily on a single American provider. Hoekstra interpreted that broader shift as a signal that Canada may be moving away from SpaceX itself. At SpaceBound, he suggested that Washington and American companies would plan accordingly if Canada chose other partners. For Ottawa, however, diversification is being framed less as a ban on U.S. technology than as an effort to avoid strategic dependence.
Canada’s growing relationship with Europe shows that this shift did not begin with the latest tariff fight. Canada has cooperated with the European Space Agency since the 1970s and is the agency’s only non-European cooperating state. The current agreement runs to 2030. The Canadian Space Agency says Ottawa committed an additional €407.71 million—about C$664.6 million—to ESA programs announced in late 2025, and expects at least 45 Canadian organizations to participate in ESA missions and activities in 2026–27. Canada also signed a security-of-information agreement with ESA this year to expand access to sensitive programs. In other words, the European option is a long-standing partnership being scaled up, not a relationship invented simply to replace Washington.
NORAD and Golden Dome Make the Space Question a Defence Question
Hoekstra also linked space cooperation to continental defence, where the stakes are considerably higher than commercial satellite contracts. He said Washington is still waiting to see how Canada wants to participate in future missile-defence architecture, including the Trump administration’s Golden Dome initiative, and warned that the United States will make its own geographic and security decisions if Canada chooses not to participate. His message was that American planning will continue whether Ottawa joins every project or not. That adds pressure because modern missile warning, communications and surveillance increasingly depend on assets in space as well as sensors spread across the Arctic.
Canada is not starting from zero. National Defence says the federal government is investing C$38.6 billion over 20 years to modernize its contribution to NORAD, the unique binational command responsible for aerospace warning and defence of North America. The program includes new over-the-horizon radar, command-and-control upgrades, air weapons, northern infrastructure and space-based surveillance. Defence officials have also said they are examining options for additional Canadian investment in integrated air and missile defence and exploring how future Canadian and U.S. investments could complement one another. The unresolved issue, therefore, is not whether Canada works with the United States on continental defence; it already does. The question is how far that integration should extend into the next generation of missile and space systems.
Ottawa’s Diversification Push Is Broader Than Space
The space debate sits inside a much larger Canadian economic strategy. The federal government has set a goal of doubling exports to non-U.S. markets over the next decade, which it says would add roughly C$300 billion in annual trade by 2035. Global Affairs Canada reported that non-U.S. exports rose 11.1% in 2025 while exports to the United States fell 3.7%, pushing non-U.S. destinations to 32.8% of Canadian exports—the highest share in more than four decades. Carney said again on October 21 that Canada remains on track to double non-U.S. exports over the next 10 years.
That strategy does not amount to replacing the United States. Even after the recent shift, roughly two-thirds of Canadian exports still go south of the border, and decades of shared infrastructure make many sectors difficult to redirect quickly. Hoekstra used that reality to argue that Canada should be cautious about assuming Europe, China or other markets can offer the same scale and accessibility. Ottawa’s answer is that diversification is insurance: more customers, more trade routes and more suppliers reduce the damage any single partner can inflict. The tension is clear. Washington sees Canada’s search for alternatives as a potential retreat from a highly successful partnership; Ottawa increasingly sees excessive dependence on the United States as a strategic vulnerability.
The Tariff Fight Was Still Moving After Hoekstra Spoke
The trade dispute continued to evolve almost immediately after Hoekstra’s appearance. On October 23, the White House announced another modification to the products covered by its Section 338 tariffs, with the changes scheduled to take effect October 30. The administration said it would remove some products, including certain plywood sheets, paper goods, machinery, refrigeration equipment, packing crates and boxes, while adding other categories such as certain valves, carpets and waste products. The 50% Section 338 rate remains in place for covered goods, and the White House said the duties continue to apply regardless of whether those products otherwise qualify under CUSMA.
That update captures why the argument over terminology is unlikely to disappear. The relationship is not severed: hundreds of billions of dollars in trade continue, astronauts are flying on shared missions, NORAD remains operational and both governments still have powerful incentives to reach workable arrangements. At the same time, the rules facing individual companies can change within weeks, and the economic effects are no longer theoretical. The PBO’s October assessment—which incorporated measures in effect as of October 1, before the newest product reshuffle—estimated that if the trade measures remain permanent, Canada’s real GDP could be 1.4% lower after five years than under its pre-tariff baseline, with employment down by as much as 185,000 jobs. Whether governments call that a trade war or a tariff negotiation, the strategic relationship is being tested in real time—and space has become one of the places where the consequences could extend well beyond trade.
