UK, Canada AI security partnership

Highlights

UK and Canada renew AI security partnership, building on the May 2024 Science of AI Safety and 2025 Growth and Innovation agreements to address frontier AI risks.
Collaboration prioritizes interoperable AI security standards, enhanced Five Eyes information-sharing, and joint evaluation activities to support international AI governance.
UK plans to make AI central to its G20 Presidency in 2025, while both nations call for action on cyber AI risk and endorse the UN's Call for Control of Frontier AI Models.

Expanded cooperation on standards and risk sharing

As reported by GOV.UK, the renewed agreement builds on the UK-Canada Science of AI Safety Partnership announced in May 2024 and the UK-Canada Growth and Innovation partnership signed in 2025. The two governments say the collaboration combines Canada’s AI research strengths with the UK’s expertise in AI testing and evaluation as both countries respond to emerging frontier AI risks.

The renewed focus prioritises three areas. The first is AI security standards, including work on interoperable standards that support wider adoption of appropriate security practices and identify priority areas for future international cooperation.

The second is stronger information-sharing arrangements, including through appropriate Five Eyes channels for sensitive reporting. The two countries also plan to share lessons on domestic resilience to promote best practice and strengthen their societies and economies.

Broader policy push on AI security

The third priority is expanded technical cooperation, including regular exchanges on frontier AI capabilities, emerging risks, evaluation methodologies and best practice. The partnership also explores staff exchanges and coordinated evaluation activities to deepen institutional links and knowledge-sharing.

The announcement marks the latest step in a wider UK and Canadian push on global AI security. The text says Prime Minister Burnham commits to putting AI at the centre of the UK’s G20 Presidency next year, while Prime Minister Carney signs the Call for Control of Frontier AI Models launched at the UN General Assembly on September 21.

The governments also point to existing national security cooperation and their Five Eyes relationship. In June 2026, they jointly call on organisations to act on rapidly evolving cyber AI risk, underscoring the growing overlap between AI governance, cybersecurity and international standards-setting.

In our earlier coverage of Meta’s legal challenge to the UK Online Safety Act regime, we detailed the dispute over how Ofcom calculates regulatory fees and maximum fines for large platforms. The case focuses on whether the watchdog can base exposure on worldwide revenue rather than UK revenue, alongside related arguments about how penalties are assessed when multiple services under the same corporate group are involved.
