The UK and Canada have renewed their AI security partnership, committing to closer cooperation on standards, information-sharing and the testing of advanced artificial intelligence systems. The Cabinet Office announced the agreement on 13 October 2026, as the UK Government also outlined plans to expand the use of AI in cyber defence and prepare for serious incidents involving autonomous AI agents.

The announcements reflect a growing policy focus on making powerful AI systems safer to develop and deploy while using the technology to help defend public services. They are not, by themselves, evidence that a new law has already come into force: the UK Government says it will explore possible changes to the cyber security regime and work through the details with Parliament, technical experts and affected operators.

What the renewed UK-Canada agreement covers

According to the Cabinet Office, the renewed partnership builds on cooperation first announced in 2024. It brings together Canada’s AI research strengths and the UK’s work on testing and evaluating AI systems. The governments have identified three main areas for closer work.

Shared standards for AI security

The countries intend to collaborate on interoperable standards so that organisations can recognise and adopt appropriate AI security practices. Common approaches could help developers and users assess systems against clearer expectations, although the announcement does not set out a single new mandatory standard or a timetable for implementation.

More information-sharing

The agreement includes stronger information-sharing arrangements, including through appropriate Five Eyes channels for sensitive reporting. The aim is to help both countries understand emerging AI security risks and share lessons about improving resilience across society and the economy.

Closer technical cooperation

The partners also plan regular exchanges on advanced AI capabilities, emerging risks, evaluation methods and good practice. They will explore staff exchanges and coordinated evaluation activities between the UK AI Security Institute and Canada’s AI Safety Institute.

The official announcement is available from the UK Government’s UK-Canada AI security partnership page.

UK expands AI-assisted cyber defence work

The partnership follows a separate UK Government announcement on 12 October setting out additional measures to strengthen national defences against AI-related risks. The Government said two pilot projects had already helped identify and fix more than 1,000 potential cyber vulnerabilities across government systems and detect potential cyber threats.

Officials said the programme would be expanded to help protect public services, while the Government considers whether parts of the Cyber Security and Resilience Bill regime should be strengthened. Areas under consideration include identifying and reporting serious AI incidents and near misses, and preparing responses to incidents involving autonomous AI agents that can carry out complex tasks with limited human supervision.

The Government’s AI risk announcement says the AI Security Institute is also conducting evaluations of the latest generation of advanced AI models. The proposed policy work is still being developed; the announcement does not provide a final set of new statutory reporting duties.

Why businesses and public services should pay attention

AI can support threat detection and help security teams find weaknesses, but increasingly capable systems can also create new risks if they are misused or behave unexpectedly. For organisations that rely on digital services, the challenge is to use AI defensively without assuming that automated tools remove the need for human oversight, testing and incident planning.

Businesses should continue to apply established cyber-security basics: keep software patched, limit administrative access, maintain tested backups, train staff to recognise phishing and make sure someone is responsible for acting on security alerts. Organisations supplying essential services should also follow relevant NCSC guidance and monitor official updates as the policy proposals develop.

What happens next?

The renewed international partnership sets out areas for cooperation, rather than a completed technical programme with published deadlines. The UK and Canada say they will work on standards, information exchange and coordinated evaluation. In the UK, further detail on possible legislative changes and the handling of AI-agent incidents is expected to be developed with policymakers and technical specialists.
