1. Five Eyes cyber agencies warn AI threats will outpace defences in months

The Five Eyes cybersecurity agencies issued a joint advisory warning that frontier AI models are accelerating cyber risks so quickly that security assumptions can become outdated in months, not years.

The advisory calls on organizational leaders to treat cyber resilience as a core business risk and to integrate AI tools into defence strategies.

The warning follows the U.S. government ordering Anthropic to suspend access to its Mythos 5 and Fable 5 models for foreign nationals.

Prime Minister Mark Carney said Canada must develop its own AI models to avoid overreliance, while the U.S. cyber agency CISA cut patching deadlines to three days citing AI threats.

Key facts:

• Five Eyes agencies (Canada, US, UK, Australia, New Zealand) issued joint statement on Monday.
• Statement warns frontier AI models transform cyber risk in months, not years.
• U.S. government ordered Anthropic to restrict Mythos 5 and Fable 5 to foreign nationals.
• Canadian PM Carney said Canada must develop its own AI models.
• CISA reduced government vulnerability patching deadlines to three days due to AI threats.

Why it matters: The joint advisory signals an escalation in how state and non-state actors will conduct cyber operations, forcing organizations across North America to accelerate security updates and invest in AI-driven defences.

For Canada and the US, the restriction on Anthropic's models highlights tensions between allied intelligence sharing and technology sovereignty—pushing Ottawa to prioritize domestic AI development.

The compressed timeline means critical infrastructure, defense supply chains, and Five Eyes intelligence-sharing platforms face immediate pressure to overhaul cyber posture or risk exploitation.

2. USMCA review passes July 1 without extension, entering unpredictable phase

The formal review of the United States-Mexico-Canada Agreement on July 1 will not produce a 16-year extension, as confirmed by the lack of a deal among the three parties.

Mexico and the United States have scheduled a third round of negotiations for late July, but Canada and the U.S. have not yet begun formal talks.

President Donald Trump has wavered publicly, telling reporters at the G7 conference in Evian-les-Bains that he would "rather have it terminated" but "may sign it."

The treaty remains in force for a decade with annual reviews, and any party can withdraw with six months’ notice. Canadian negotiators are preparing to strike a deal if an opportunity arises, but face ongoing uncertainty and difficult bilateral irritants.

Key facts:

• No 16-year USMCA extension will occur on July 1, 2025.
• Mexico and the U.S. scheduled a third negotiation round for late July.
• Canada and the U.S. have not yet begun formal USMCA negotiations.
• Trump told reporters he would rather terminate the deal but may sign.
• The treaty remains in force for a decade with annual reviews.

Why it matters: The failure to extend USMCA on schedule pushes North American trade into a limbo of bilateral deal-making and ongoing uncertainty.

Canada risks prolonged sectoral tariffs on autos, metals, and lumber unless negotiators can secure relief from a mercurial U.S. president.

The outcome will shape supply chains, critical minerals cooperation, and defense procurement alignment, with midterm elections in November as a potential deadline for any breakthrough.
