European Commission President Ursula von der Leyen put forward the proposal to take relations between Canada and the European Union to a new level on September 16, 2026. Von der Leyen said Canada could become the EU’s first associate member and proposed an alliance extending beyond the existing free-trade framework, CETA.
The model would not mean that Canada becomes a full member of the EU. The proposed special or associate-member status would be based on closer cooperation in the economy, economic security, defense, supply chains and strategic resilience, without giving Canada full participation in the EU’s decision-making mechanisms.

Economic and security partnership beyond CETA
CETA forms the foundation of economic relations between the EU and Canada. The new alliance proposal would expand this trade-based relationship around shared prosperity and economic security goals, while promoting more coordinated action in strategic supply chains and resilience.
Canadian Prime Minister Mark Carney is seeking a distinctive economic and security alliance with Europe rather than pursuing EU membership. This approach suggests that both sides could consider a partnership formula separate from full membership.
Proposal for a European response mechanism
Von der Leyen said Europe should establish a NATO-like European response mechanism to address drone incidents, acts of sabotage and cyberattacks on the continent. The proposal is being considered as a complementary structure that would strengthen Europe’s ability to respond to crises using its own capabilities; however, the mechanism’s definitive legal model and mandate have not yet been set out.
The idea of a European Security Council is also part of the same security framework. Von der Leyen said partners such as the United Kingdom, Canada, Norway and Ukraine could take part in the council. The council has not yet been established; details concerning its membership structure, decision-making powers and the binding nature of its decisions remain unclear.
Partnership signed in 2025 provides the foundation
The EU and Canada signed a security and defense partnership at the 20th EU-Canada Summit held on June 23, 2025. The agreement covered deeper cooperation in military mobility, interoperability, maritime and space security, and the defense industry.
Economic security, stability and the rules-based international order were key topics at a meeting in Brussels in February 2025 between Canadian Prime Minister Justin Trudeau, European Council President António Costa and Ursula von der Leyen. Contacts aimed at involving Canada more closely in Europe’s defense architecture and the EU’s defense procurement initiatives also intensified during 2025-2026.

NATO ties and steps that remain uncertain
The EU and Canada continue to maintain their shared defense ties within NATO. Security and defense documents from 2025 emphasized that NATO remains the foundation of Euro-Atlantic security and that the EU-NATO partnership is complementary. There is therefore no confirmed decision for the new mechanism to replace NATO.
Implementing the proposal will require defining the legal framework, securing political agreement among EU member states and deciding the level of access Canada will have to EU institutions. The division of responsibilities between the new structure and NATO will also need to be clarified. Uncertainty over Europe’s security role and the United States’ position in transatlantic defense forms the initiative’s geopolitical backdrop, while no official decision has been announced to sever the EU’s and Canada’s NATO ties.
