On 30 October 2026, in Montreal, the 21st summit between the European Union and Canada concluded with a joint declaration launching an "Alliance for the Future". Among the day's announcements, one line directly concerns AI infrastructure: the leaders welcome "Canada's participation in the European High Performance Computing Joint Undertaking (EuroHPC JU)", which should "strengthen links between our supercomputing resources" and prepare deeper integration of AI innovation ecosystems.
The Joint Undertaking confirmed the same day, in its own press release, that Canada had officially become its 39th participating state. In her statement after the summit, Ursula von der Leyen summarised the measure in one sentence: "we are opening European supercomputing infrastructure to Canada".
A seat on EuroHPC's governing board
EuroHPC JU is a European legal entity that pools funds from the Union and participating states to purchase supercomputers and fund research in high-performance computing. It has already acquired 12 supercomputers across Europe, including JUPITER in Germany and Alice Recoque in France, presented by the Joint Undertaking as Europe's first exascale systems. It also oversees 19 AI Factories and 13 antennas. Regulation (EU) 2026/150, in force since 20 January 2026, extended its mandate to AI gigafactories and quantum technologies.
Participating state status first gives a seat on the governing board. According to the Joint Undertaking's governance page, this board, composed of the Commission and one representative per participating state, is responsible for strategic choices and funding decisions, including all public procurement. As of 2 November 2026, this page already lists Canada, represented by Nipun Vats, with Sheila Kennedy as alternate. Ottawa will therefore sit where decisions are made on machine purchases, selection of AI factories and implementation of gigafactories. The real weight of this voice will depend on the participation conditions, which have not been published.
Canada thus joins the eleven other participating states outside the Union, including the United Kingdom, Switzerland, Norway, Turkey and Israel. It is the only member from the Americas.
Access for researchers and start-ups still unclear
EuroHPC's press release states that Canada will, "like other participating states", be able to access the HPC, AI and quantum computing resources provided by the Joint Undertaking, and that its scientists will be able to collaborate with their European counterparts. Evan Solomon, Canada's Minister of Artificial Intelligence and Digital Innovation, speaks of "new opportunities for Canadian researchers and innovators".
Free access, reserved for the public sector, research and SMEs, is through calls for proposals evaluated by independent experts; other commercial uses are charged on a pay-per-use basis. For AI factories, the "industrial innovation" track offers three levels (Playground, Fast Lane up to 50,000 GPU hours, Large Scale beyond), open free of charge to AI SMEs and start-ups. The AI factories FAQ lists applicants established in a "participating state" among those eligible, but the list of countries displayed under that answer, which concerns machines acquired before 2020, did not yet mention Canada on 2 November.
EuroHPC's access policy (December 2025 version) ties eligibility to the programme that funded each machine: Horizon 2020 for pre-exascale and petascale systems, Horizon Europe or the Digital Europe Programme for exascale and mid-range systems. Canada has been associated to Horizon Europe since 2024, the Joint Undertaking recalls. On paper, the access policy opens machines acquired after 2020, including JUPITER, Alice Recoque and AI factories, to countries associated to this programme, but the lists of eligible countries displayed by EuroHPC do not yet mention Canada. The same policy provides another regime for countries with which the Commission has signed a digital partnership including high-performance computing activities: access may be granted by the governing board on a reciprocity principle, with time offered on European machines to be offset by equivalent time on the partner country's supercomputers. Canada has a digital partnership with the Union, which Roberto Viola, Director-General of DG CNECT, cites in EuroHPC's press release, but none of the announcements indicate whether it covers high-performance computing. Neither the joint declaration nor EuroHPC's press release details the concrete application of these rules to Canada, nor the amount of any Canadian financial contribution.
Public computing becomes a tool of EU external partnerships
Canada's accession is not isolated. On 23 September 2026, EuroHPC JU already launched the EU-Latin America and Caribbean AI supercomputing network, linked to the Global Gateway strategy and coordinated by the Barcelona Supercomputing Center, with Inria among the seven European partners. The format differs: a two-year cooperation project with seven Latin American countries on one side, a full seat on the board on the other.
For the editorial team, these two announcements in quick succession show that the Union is now using its computing infrastructure as an instrument of its partnership policy, from a board seat for a G7 member to a cooperation project for Latin America. Anders Dam Jensen, Executive Director of EuroHPC JU, presents the accession as reflecting "the growing importance of international partnerships" in building a sovereign European supercomputing ecosystem. On the Canadian side, the gain is influence over infrastructure for which Ottawa has, to date, announced no quantified contribution.
For French users, nothing changes in the short term: access calls remain open under the same conditions, and the French AI factory remains in the network. The effect will be felt on the board, where one more voice will weigh on the location and timing of future machines, and on the access criteria for gigafactories, which Europe wants to use as a catch-up lever, as ActuIA detailed in September regarding the European AI funding strategy. Several countries have already used these machines to train their national language models, like the Portuguese example analysed in July.
The rest of the summit's digital agenda
The joint declaration also announces the conclusion of substantive negotiations on a digital trade agreement, presented by Ursula von der Leyen as "the digital arm of CETA". It sets out orientations: cooperation on access to large computing infrastructure for AI, "including AI factories", with particular attention to start-ups, SMEs, researchers and public administrations, and work towards mutual recognition of conformity assessment results for AI systems. This last point is only an objective at this stage. The two memoranda of understanding on AI and digital credentials cited in the text date from 8 December 2025, signed at the first Canada-EU Digital Partnership Council.
The next visible step will be the publication of access calls mentioning Canada among eligible countries, and the first meeting of EuroHPC's governing board at which its representative will sit.
