Canada officially joins GCAP as observer

Italy, Japan and the UK welcomed Canada's participation as an Observer in the Global Combat Air Programme (GCAP), marking the first expansion of the trilateral initiative.

After reports in the last few weeks about discussions being in progress, Canada has officially joined the Global Combat Air Programme (GCAP) as an Observer. The development marks the first formal expansion of the trilateral sixth-generation fighter initiative led by Italy, Japan, and the United Kingdom.

The announcement was made on July 21, 2026, following a meeting in London between Italian Defence Minister Guido Crosetto, Japanese Defense Minister Koizumi Shinjirō, UK Secretary of State for Defence Wes Streeting, and Canadian Minister of National Defence David J. McGuinty. "The Ministers of Italy, Japan and the UK welcomed Canada's participation as an Observer, and all four Ministers welcomed the opportunities arising from this important development," said the joint statement.

Canada’s observer status will provide Ottawa with greater insight into the Programme while allowing it to deepen its understanding of GCAP’s governance, operational capabilities, industrial framework, and associated security requirements. The status also opens the door to broader cooperation opportunities.

The three founding nations described the new development as an important step toward strengthening cooperation among trusted partners in response to an increasingly complex international security environment. Additionally, they said "Canada's involvement will also support greater alignment of strategic priorities and deepen mutual understanding of future combat air ambitions."

Canada's interest in GCAP

Earlier this year, officials have revealed that Canada is looking to join GCAP as an observer nation. This was reportedly the main topic of a meeting on Mar. 6, 2026, between Japanese Defense Minister Shinjiro Koizumi and Canada's Minister of National Defense, David McGuinty.

At the time, the Asahi Shimbun reported that the three current partner nations planned to hold a defense ministers' meeting in the UK as early as July to formally announce Canada's participation. This indeed materialized with the announcement in London on July 21.

Canada, who had been a long term defense partner of the U.S., has invested heavily in the F-35 program, with the first aircraft expected to be delivered soon. However, with the deterioration of the relations with the U.S., Canada also started looking elsewhere for its modernization of the armed forces.

Observer status

Canada’s observer status does not make it a full member of the Global Combat Air Programme (GCAP). Instead, it provides Ottawa with privileged access to the governance, capabilities and industrial framework, as well as the related security requirements and wider partnering opportunities.

However, this privileged access does not imply that Canada will have decision-making authority. This, in fact, will remain the responsibility of Italy, Japan and the UK.

Nevertheless, the observer status could facilitate future discussions on industrial cooperation and potential long-term participation, should the Canadian government decide to pursue a more substantial role. An upgrade to full partner is unlikely at the moment, due to Japan's insistence that no more partners are added to the development of the aircraft, in case it leads to delays in the platform entering service.

Anyway, the Ministers reaffirmed their commitment to maintaining GCAP as an open and collaborative program, emphasizing continued engagement with trusted allies and partners. Canada's involvement in GCAP, even in a limited capacity, could benefit the current partner nations, allowing for reduced overall airframe costs as the number of deliveries increase.

It is thus likely the GCAP partners will evaluate how closer cooperation with Canada could benefit the program, ahead of a future decision, possibly after the demonstrator enters the flight testing phase.
