As the global energy landscape undergoes a profound transformation, the Republic of Korea is strategically recalibrating its supply chains to ensure both economic resilience and national security. In a move that underscores the deepening bilateral ties between Seoul and Ottawa, South Korea has significantly ramped up its imports of Canadian crude oil. This tactical pivot is occurring against the backdrop of a high-stakes diplomatic and industrial push: a massive multibillion-dollar naval procurement program that has become a centerpiece of Korea’s strategic engagement with Canada.
For years, South Korea has sought to diversify its energy imports to mitigate risks associated with over-reliance on Middle Eastern suppliers. Recent data confirms that the volume of Canadian crude oil flowing into Korean refineries has seen a substantial increase, reaching approximately 16 million barrels in 2023, a jump of more than three times the 4.88 million barrels recorded in the previous year. This surge reflects the growing importance of the Trans Mountain pipeline expansion and Canada’s efforts to reach Asian markets with its energy exports. According to reports from industry analysts and trade data, this shift aligns with Korea’s broader strategy to secure stable, democratic-aligned energy sources.
The Strategic Nexus of Energy and Defense
The decision to expand energy cooperation is not merely a commercial transaction; it is inextricably linked to the geopolitical ambitions of the South Korean government. Seoul is currently engaged in an intensive international campaign to secure a major defense contract, colloquially referred to as the “60 trillion won” submarine project. This initiative involves the potential export of advanced diesel-electric submarines to the Canadian Navy, which is looking to modernize its aging Victoria-class fleet.
The stakes are high. South Korean defense contractors, led by giants such as Hanwha Ocean and HD Hyundai Heavy Industries, are competing against international rivals to demonstrate that they can provide not only the hardware but also the industrial partnership Canada requires. By increasing its intake of Canadian natural resources, Seoul is signaling that it is a long-term, reliable partner for Ottawa—a “win-win” narrative that diplomats hope will sway decision-makers in the Canadian federal government. The Canadian government has publicly acknowledged its interest in replacing its current submarine fleet, noting the necessity of maintaining a credible naval presence in the Pacific and Arctic theaters.
Industrial Diplomacy: Beyond the Balance Sheet
The diplomatic efforts to solidify this partnership have moved beyond formal high-level meetings. Recent outreach by senior South Korean officials has included site visits to Canadian manufacturing hubs, particularly those involved in automotive and high-tech component production. These visits serve a dual purpose: they showcase the potential for integrated supply chains and reassure Canadian labor unions and industrial leaders that a deal with South Korea would result in technology transfers and job creation within Canada.
This “industrial diplomacy” is a hallmark of current South Korean foreign policy, which emphasizes the “value-based” partnership between the two nations. Both countries are members of the G20 and share a commitment to democratic values, making the defense procurement project a natural extension of their existing bilateral agreements, including the Canada-Korea Free Trade Agreement (CKFTA). The CKFTA, which came into force in 2015, remains the foundational framework that facilitates this deepening economic integration.
Key Takeaways: The Korea-Canada Partnership
- Energy Diversification: South Korea has tripled its reliance on Canadian crude, moving to insulate itself from volatility in traditional energy markets.
- Naval Modernization: Canada is in the preliminary stages of exploring options for its future submarine fleet, with South Korean firms positioning themselves as top-tier contenders.
- Economic Synergy: The relationship is being framed as a strategic alliance that spans energy security, defense technology, and supply chain resilience.
- Diplomatic Outreach: High-level engagement is focused on demonstrating the long-term industrial benefits of deeper bilateral cooperation.
What Happens Next?
While the momentum behind the energy and defense deals is palpable, the path forward remains subject to the rigorous procurement processes of the Canadian Department of National Defence. Any final agreement regarding the submarine project will require extensive vetting, technical evaluation, and parliamentary approval in Ottawa. Observers anticipate that the next major milestone will be the release of a formal Request for Information (RFI) or a more detailed update on the Canadian government’s procurement timeline for the Patrol Submarine Project (CPSP).

As the situation develops, the global community will be watching to see if Seoul’s multi-pronged approach—combining energy imports with defense technology—proves successful in securing one of the most significant military export contracts in recent history. For now, the integration of energy trade and defense aspirations continues to define the trajectory of the Seoul-Ottawa relationship.
