Canada and the United States are reading from highly similar threat scripts, but alignment in assessment does not mean alignment in capacity or posture. Both governments now foreground an expanded notion of risk that moves beyond intelligence collection to include pre-positioning, supply chain exploitation, ransomware as national risk, and the malign use of emerging technologies. The policy and operational implications of that shift require a clearer bilateral roadmap if North American resilience is to keep pace with adversary intent and technique.

The Canadian Centre for Cyber Security’s National Cyber Threat Assessment 2025-2026 identifies the People’s Republic of China as the most sophisticated cyber threat to Canada and highlights the growing brazenness of state actors, the persistence of organized cybercrime, and the rapid commoditization of malicious tools. Its analysis ties these threats to real economic and societal impact and explicitly calls out the risk to civilian critical infrastructure in the event of broader geopolitical escalation. That framing marks a deliberate move from episodic incident response toward strategic resilience planning.

From the U.S. side, the intelligence community and national cyber leadership present comparable judgements. The Office of the Director of National Intelligence’s Annual Threat Assessment and the 2024 Report on the Cybersecurity Posture of the United States emphasize China, Russia, Iran, and North Korea as enduring state risks while elevating ransomware, supply chain compromise, commercial spyware, and the security implications of AI as cross-cutting threats. U.S. reporting has repeatedly stressed that adversaries are not limiting themselves to espionage and theft but are preparing options for disruption and manipulation of critical systems.

One concrete point of alignment that matters operationally is the assessment that some state-sponsored actors are pre-positioning inside networks that underpin critical infrastructure. U.S. agencies identified Volt Typhoon as a persistent PRC-linked operation focused on long-term access to U.S. IT networks that could enable OT disruption. Canadian analysts have reached parallel judgements about state actors’ willingness to target systems that have downstream physical effects. That shared analytic conclusion already underpins joint advisories, coordinated hunting, and cross-border information exchanges, but it also exposes dependence on rapid, bilateral incident playbooks for when stealthy intrusions are detected.

Ransomware and the cybercrime-as-a-service economy are another area where Canada and the U.S. have matching strategic priorities. Both nations see increasingly specialized criminal supply chains, widespread use of extortion-as-a-service, and the weaponization of stolen credentials and botnets to magnify impact across sectors. The result is a shared demand signal for better cross-border intelligence sharing, harmonized reporting requirements, and cooperative disruption operations that combine law enforcement, intelligence, and regulatory levers.

Despite these common threat judgements, gaps persist in how the two governments convert analysis into synchronized action. Canada’s 2024 budgetary commitment and the Cyber Centre’s expanded analytical products strengthen its national capacity, yet Canada still confronts scale and coverage limits compared with the U.S. federal enterprise. The United States has pushed implementation of a national strategy, updated posture reporting, and sectoral directives, while also working to broaden public private partnerships. Those differences create friction when rapid, coordinated response is required for incidents that cross the border or cascade through shared infrastructure.

Operational cooperation has promising footholds. Five Eyes relationships and bilateral engagements are already driving joint publications and coordinated advisories, and Canadian and U.S. agencies have co-authored incident alerts and shared operational tradecraft. These mechanisms are valuable, but need extension into shared playbooks for: cross-border incident notification, privileged credential resets that cross organizational boundaries, joint forensic timelines, and legal authorities mapping so containment and remediation do not stall on jurisdictional questions. Strengthening these operational ties is as important as aligning strategic assessments.

Where the bilateral partnership must deepen now

  • Standardize reporting thresholds and timelines. Countries and companies still use different triggers for escalation. A compact that aligns what constitutes ‘‘critical incident’’ and prescribes joint notification timelines would reduce confusion when a pre-positioning campaign or disruptive event is discovered.

  • Map cross-border critical dependencies. Energy, rail, pipelines, and telecommunications are tightly coupled across the border. A shared inventory, with controlled access and robust protections, would let responders prioritize mitigation measures that prevent cascading failures.

  • Jointly operationalize SBOMs and secure software procurement. Supply chain exploitation remains a high-leverage vector. Harmonized rules for software bills of materials, coordinated vulnerability disclosure timelines, and synchronized procurement standards would limit windows of exposure.

  • Scale coordinated disruption and legal tools. Tactical success against ransomware and criminal platforms requires synchronized law enforcement and financial actions. Expanding bilateral frameworks for mutual legal assistance, asset freezes, and coordinated takedowns must be prioritized.

  • Create shared AI threat libraries and red teams. Both governments identify AI as a capability that can amplify attacks and defenses. A shared catalogue of AI-enabled threat patterns, plus joint red team exercises focused on AI-enabled phishing, automated reconnaissance, and manipulated data poisoning, would make defenses more anticipatory.

Final assessment

At the analytic level, Canada and the United States are closely aligned on the nature and trajectory of the cyber threat environment. That alignment creates significant opportunity. Where the partnership falls short is in translating common threat judgements into integrated, cross-border operational architecture. To be clear, the ingredients for stronger coordination exist: intelligence sharing frameworks, joint advisories, and complementary policy reforms. The near-term challenge is engineering a durable, legal, and technical scaffolding that lets both countries act in hours and days rather than weeks and months when the shared digital fabric is under stress. The alternative is to accept an outcome where adversaries win time through stealth and fragmentation while defenders barter over authority and method. That is not a choice Canada and the United States should leave on the table.
