Canadian Prime Minister Mark Carney and leaders from five Nordic nations have signed a landmark joint declaration in Oslo to deepen military cooperation and secure the Arctic region. This strategic pivot marks a significant shift in Canadian foreign policy, as the nation seeks to reduce its long-standing defense and trade reliance on the United States. The agreement emphasizes joint industrial projects and explicitly backs Greenland's sovereignty.

Strategic Military Cooperation

The six nations agreed to deepen ties in military procurement and industrial cooperation to bolster northern security.

Shift from US Dependence

Prime Minister Mark Carney is pursuing a 'middle power' strategy to diversify Canada's international alliances beyond the United States.

Arctic Sovereignty and Stability

The declaration includes explicit support for Greenland's sovereignty and a commitment to a rules-based order in the Arctic.

Canadian Prime Minister Mark Carney met with the leaders of five Nordic countries in Oslo on March 15, 2026, signing a joint declaration to deepen cooperation in military procurement and Arctic security as part of a broader strategy to reduce Canada's defense and trade dependence on the United States.

The summit brought together Carney and the prime ministers of Norway, Sweden, Finland, Denmark, and Iceland in what participants described as a gathering of middle powers seeking to chart an independent course. Norwegian Prime Minister Jonas Gahr Støre described the cooperation as middle powers forging a path in terrain he called "uncharted." Danish Prime Minister Mette Frederiksen stated that the old world order is gone, framing the Oslo meeting as a response to shifting global dynamics. The gathering also included Icelandic Prime Minister Kristrún Frostadóttir, Swedish Prime Minister Ulf Kristersson, and Finnish Prime Minister Petteri Orpo. The joint declaration signed by all six leaders covered military procurement cooperation and Arctic security, according to reporting by Reuters and Bloomberg Business. The leaders also expressed backing for Greenland's sovereignty, a notable signal given recent tensions over the territory's status.

Carney, who has served as Canada's 24th prime minister since 2025, has positioned the Nordic outreach as a central pillar of his foreign policy. The strategy, described in multiple reports as a "middle power" approach, aims to diversify Canada's defense procurement and security partnerships beyond its traditional reliance on the United States. Canada and the Nordic countries share geographic proximity through the Arctic, giving the alliance a practical strategic dimension beyond diplomatic signaling. According to Bloomberg Business, the declaration specifically addressed Arctic security ties, an area of growing geopolitical competition. The Oslo meeting followed a period of heightened concern in Canada about U.S. trade and defense policies, with Carney's government seeking to build alternative partnerships. Web search results indicate Carney also planned to observe a NATO exercise in Norway before traveling onward.

Canada and the Nordic countries have long maintained ties through shared membership in NATO, with the exception of historically neutral Sweden and Finland, both of which joined the alliance in 2023 and 2024 respectively following Russia's full-scale invasion of Ukraine. The Arctic has grown in strategic importance as climate change opens new shipping routes and exposes natural resources, prompting increased military attention from multiple powers. Canada has historically conducted the bulk of its defense procurement in partnership with the United States, making the Oslo declaration a notable shift in orientation. The Nordic Council, the formal body for inter-parliamentary Nordic cooperation formed in 1952, has provided a long-standing institutional framework among the five Nordic states, though Canada's participation in this new grouping is bilateral and security-focused rather than parliamentary.

The declaration's backing of Greenland's sovereignty carried particular weight given recent public statements by U.S. officials regarding the territory, which is an autonomous part of Denmark. The Nordic leaders' unified stance on Greenland, alongside Canada's endorsement, amounted to a collective reaffirmation of existing international norms on territorial integrity. The Business Insider report framed the Oslo summit as Canada shifting its strategic focus northward and away from Washington. The New York Times noted that Nordic leaders praised Carney during discussions on Arctic security, reflecting a warm reception for Canada's outreach. According to web search results, Carney's Liberal government held 169 seats in parliament at the time of the summit, three short of a majority, meaning the foreign policy initiative was pursued amid ongoing domestic political maneuvering. The Oslo declaration nonetheless represented a concrete diplomatic output, with all six governments committing to the joint text on military procurement and security cooperation.
