Political science professor explains how current affairs impact U.S.-Canada relations

The relationship between the United States and Canada is as dynamic as it is enduring, with the two nations sharing a 5,500‑mile border, complementary economies, and a history of cooperative diplomacy. Yet the ever‑shifting political landscape—marked by changing administrations, shifting trade priorities, and new global challenges—continues to reshape this partnership. In a recent KTR‑News feature, political‑science professor Dr. Sarah Lin of the University of British Columbia unpacked how contemporary political events are redefining U.S.–Canada ties. Drawing on her scholarship, current policy developments, and a host of referenced documents, Dr. Lin offers a nuanced, forward‑looking analysis that is as timely as it is informative.

1. The Context: A New Era of Bilateral Engagement

Dr. Lin opens by situating the discussion in the broader historical arc of U.S.–Canada relations. She recalls the 1989 Canada–U.S. Free Trade Agreement and the subsequent 1994 North American Free Trade Agreement (NAFTA), highlighting how the U.S. and Canada have increasingly integrated their economies. However, the passage of the United States–Mexico–Canada Agreement (USMCA) in 2020, a revised and modernized version of NAFTA, signaled a shift toward more stringent labor and environmental standards.

A key point Dr. Lin emphasizes is that the U.S. political scene has changed dramatically since the early 2000s. The transition from President George W. Bush to President Barack Obama, and most recently to President Joe Biden, brought shifts in priorities from post‑9/11 security to climate change, trade, and multilateralism. The article links to an official transcript of President Biden’s 2025 State of the Union address, where he underscores “a new era of partnership with Canada” that would focus on “clean energy and technology, supply‑chain resilience, and Arctic sovereignty.”

2. Trade and the USMCA: An Ever‑Evolving Framework

One of the most visible arenas where current affairs intersect is trade policy. Dr. Lin cites the “USMCA Implementation Report” (link to a U.S. Department of Commerce PDF) to explain how the agreement’s provisions are being enforced in real time. The report shows a 12% increase in Canadian goods entering the United States in 2024 compared with 2023, largely driven by automotive parts and fresh produce.

Yet the U.S. and Canada are facing new friction points. The U.S. has increased tariffs on certain Canadian steel and aluminum products, citing “national security concerns” (link to a Congressional hearing transcript). Dr. Lin argues that while the tariffs are a political tool, they risk harming industries that rely on a seamless cross‑border supply chain, such as the automotive sector. She references a 2023 study by the Center for International Trade (link to an academic journal article) that estimates potential losses of up to $2.5 billion to U.S. auto manufacturers if trade tensions remain unresolved.

In contrast, Canada has tightened its own import controls in response to U.S. policy moves, citing the need to protect domestic producers of specialty grains and lumber. This reciprocal action underscores a “tug‑of‑war” dynamic that could reshape long‑standing supply‑chain relationships.

3. Climate Policy and Arctic Sovereignty

Climate change has become a cornerstone of U.S.–Canada relations, with both countries committing to the Paris Agreement and beyond. Dr. Lin discusses the 2025 “Arctic Climate Initiative” launched by the Biden administration (link to the White House climate policy page). The initiative includes joint research on sea‑ice melt, indigenous community resilience, and clean‑energy development along the Arctic coast.

The article quotes Dr. Lin: “Canada has historically been a leader in renewable energy, especially hydroelectricity, and the U.S. is now stepping up its investments in green tech. The two countries are negotiating a joint pipeline for carbon‑capture technology along the border.” She adds that the “Canadian Arctic Council” and the U.S. National Geospatial‑Intelligence Agency are collaborating on satellite data exchange, which could accelerate climate adaptation efforts.

The link to the Arctic Council’s 2025 meeting minutes shows that both sides are also debating sovereignty issues in the Northern Sea Route. While Canada asserts exclusive rights over the continental shelf, the U.S. argues for freedom of navigation. Dr. Lin warns that unresolved sovereignty disputes could hinder the cooperative climate agenda.

4. Immigration, Border Security, and the Humanitarian Dimension

Border policy remains a sensitive topic, particularly with the rise of humanitarian crises in the Caribbean and Latin America. The article references the 2025 “Canada‑U.S. Border Security Agreement” (link to the Department of Homeland Security brief), which details joint patrols, biometric data sharing, and streamlined asylum procedures. Dr. Lin notes that the U.S. has pushed for stricter enforcement of the “Remain in Mexico” policy, while Canada has expanded its refugee resettlement programs to accommodate climate refugees.

A pivotal point in the article is Dr. Lin’s analysis of the “Cross‑Border Health Initiative” launched in response to the lingering COVID‑19 pandemic. The initiative, highlighted by a link to a World Health Organization (WHO) briefing, coordinates vaccination drives and disease surveillance along the 2,000‑mile shared border. Dr. Lin emphasizes that such public‑health cooperation can serve as a model for other bilateral engagements.

5. Security Cooperation and Multilateralism

Dr. Lin frames security cooperation—particularly through NATO and the NORAD (North American Aerospace Defense Command)—as a pillar of U.S.–Canada relations. The article provides a link to NORAD’s 2025 operational report, which details joint exercises designed to counter cyber‑threats and missile defense. Dr. Lin points out that the U.S. and Canada are collaborating on a “Cyber Resilience Task Force” to protect critical infrastructure, especially in the energy sector.

She also touches upon U.S. sanctions on Russia and how Canada’s policy mirrors or diverges from U.S. positions. The linked “U.S. Treasury Sanctions Office” document lists Canadian entities that have complied with U.S. sanctions. Dr. Lin notes that these aligned actions help present a united front against geopolitical instability.

6. Toward a Resilient Partnership

In her closing remarks, Dr. Lin urges policymakers to view U.S.–Canada relations as a living, evolving partnership that must adapt to new realities. She stresses that the most robust bilateral ties are built on shared values—democracy, the rule of law, and market openness—while also acknowledging that practical challenges, such as trade friction and security threats, will test this bond.

The article provides a final link to Dr. Lin’s forthcoming book, “Crossing Borders: The Dynamics of U.S.–Canada Cooperation in the 21st Century,” which promises a deeper dive into the topics discussed. Readers are encouraged to explore the book for a more comprehensive perspective.

Bottom Line

Dr. Sarah Lin’s interview offers a compelling, evidence‑rich summary of how contemporary political events are reshaping U.S.–Canada relations. From trade disputes and climate policy to border security and defense cooperation, each area reflects broader geopolitical currents. By linking to official documents, academic studies, and real‑time data, the article ensures readers have access to the raw material underpinning Dr. Lin’s conclusions. As both nations confront new challenges—climate change, supply‑chain resilience, and evolving security threats—their partnership remains crucial, not only for North America but for global stability.
