Preparing Canada’s health system for conflict: a framework for civilian–military medical readiness

Key points

• Canada’s civilian health system would likely bear the clinical burden of large-scale casualty events involving Canadian or allied forces, yet the country lacks a national framework to coordinate civilian and military medical response during conflict or national emergencies.

• Fragmentation between federal military medical services and provincial and territorial health systems creates structural vulnerabilities that could delay definitive care, disrupt patient redistribution, and increase preventable morbidity during sustained casualty events.

• A national framework for civilian military medical integration should rest on 3 pillars: sustained clinical readiness through shared training and embedded personnel, scalable dual use medical capacity, and formalized coordination supported by interoperable data systems.

• Institutionalizing civilian military medical integration through shared governance, interoperable logistics, and ethical crisis planning would strengthen routine health system resilience while enabling Canada to respond effectively to conflict and other large-scale emergencies.

A major armed conflict involving Canada or its North Atlantic Treaty Organization (NATO) allies, including coalition ground combat with large-scale casualty repatriation to Canadian hospitals, could overwhelm Canada’s civilian health system well before it strains the country’s military capacity. The Canadian Forces Health Services has supported humanitarian and combat operations for decades; however, without a network of military hospitals capable of absorbing sustained high-acuity volume, its deployable medical footprint remains limited and structurally dependent on provincial trauma systems for complex surgical care and tertiary throughput.^1,2 Civilian hospitals would carry any additional clinical burden of caring for injured service members, repatriated casualties, and affected civilians. Moreover, fragmentation between civilian and military services exposes service members and civilians to avoidable harm. We explore factors leading to this fragmentation, examine the importance of and models for improved integration, and suggest urgent next steps for Canada in the current geopolitical context.

Canada’s vulnerability in the context of military conflict lies in its lack of a national framework that would coordinate large-scale evacuation of casualties, allocate scarce resources, and integrate provincial and federal surge capacity. The country also lacks a standing command structure linking Canadian Forces Health Services, provincial and territorial ministries of health, the Public Health Agency of Canada, and Canadian Blood Services during national emergencies.³

Civilian health care in Canada is already strained, and planning for potential military conflict cannot assume reserve capacity. Emergency departments and intensive care units operate near capacity, and workforce shortages persist across provinces and territories.⁴ The COVID-19 pandemic showed how even modest surges destabilize surgical programs and delay urgent interventions.⁵ Surge modelling in mass-casualty and crisis standards literature demonstrates that trauma, intensive care capacity, blood supply, and transport coordination become rate-limiting under sustained high-acuity demand.⁶ Additional demand will displace existing care unless coordination mechanisms are deliberately established in advance.

Canada’s health care systems may need to respond to any of several possible conflict scenarios. Sustained allied operations abroad would generate casualty repatriation and long-term rehabilitation needs. Domestic mass-casualty attacks — including cyber-enabled disruption of health infrastructure, such as ransomware or network intrusions disabling hospital information systems, diagnostic platforms, and patient-flow coordination — could impair hospital operations and necessitate a distributed trauma response and interprovincial patient redistribution. Northern sovereignty crises would strain aeromedical evacuation networks, remote stabilization capacity, and fragile transport corridors.⁷ In each scenario, the limiting resources would be trauma surgery, intensive care beds, blood supply, transport coordination, and real-time situational awareness. All these resources depend on digital infrastructure enabling patient tracking, hospital capacity management, and interfacility communication, which may themselves be disrupted during cyber attacks.

Civilian–military medical integration is therefore not a narrow defence concern, but a resilience strategy. Commitments in NATO Article 3 emphasize preparedness and continuity of essential services.⁸ Military medical systems’ innovations in damage-control resuscitation, structured massive transfusion protocols, delivery of care en route to hospital, telementoring, and distributed logistics have shaped civilian trauma practice.⁹ In turn, civilian trauma centres sustain the case volume and multidisciplinary coordination necessary to maintain high-acuity competence.¹⁰ Integration permits reciprocal reinforcement only when institutionalized. Informal fellowships and episodic collaborations cannot substitute for defined governance, shared accountability, and standardized activation thresholds.¹¹

Several NATO countries institutionalize civilian–military medical integration as part of national health security. In the United Kingdom, Defence Medical Services personnel are embedded within designated National Health Service trauma centres to sustain clinical readiness and provide surge capacity during national emergencies.¹¹ Nordic countries employ total-defence models that integrate civilian health systems, military medical services, and national emergency preparedness within unified planning frameworks.⁸ Germany and the Netherlands rely on structured civilian–military trauma networks, coordinated aeromedical evacuation systems, and shared training platforms to ensure interoperability during domestic disasters and multinational operations. Such models show that clinical integration, interoperable logistics, and clear governance strengthen routine health system performance while preserving rapid scalability during conflict and other large-scale emergencies.

Canada’s principal deficits are structural. No nationally endorsed doctrine defines responsibilities during conflict-related casualty events, and no standing joint operational structure links Canadian Forces Health Services with provincial bed management and aeromedical dispatch systems. Cross-jurisdictional credentialing and liability frameworks remain inconsistent. Data interoperability between federal and provincial systems is limited, which constrains capacity for real-time decisions about resource allocation.³ These weaknesses can result in delayed definitive care, inefficient patient redistribution, inconsistent triage standards, and preventable morbidity during conflict and other large-scale emergencies.

A credible national framework should rest on 3 interdependent pillars: sustained clinical readiness, scalable dual-use capacity, and formalized coordination supported by interoperable data systems.

Sustained readiness requires formal agreements that embed Canadian Forces Health Services clinicians within designated civilian trauma hubs to maintain high-acuity exposure.^10,11 Structured appointments reduce reliance on ad hoc rotations. Hub-and-spoke networks can extend shared protocols and simulation programs to regional centres. Civilian clinicians with clearly defined scope of practice and credentialing could participate in Canadian Forces Health Services–directed readiness exercises under articulated frameworks.

Scalable dual-use capacity should prioritize investments that strengthen everyday care while preserving rapid deployability. These include modular surgical capability, deployable intensive care platforms, simulation networks, and telementoring for northern and remote communities. Enhanced aeromedical coordination, blood logistics redundancy, and supply chain resilience yield continuous civilian benefit. Procurement aligned with allied interoperability standards reduces friction during multinational operations.¹¹

Formalized coordination remains the most urgent requirement. Canadian Forces Health Services, Health Canada, and the Public Health Agency of Canada should develop a joint patient movement and coordination function — in partnership with provinces and territories — to define activation thresholds, decision authority, and escalation pathways during declared emergencies. Integration with provincial bed management and aeromedical systems is essential. Standardized data elements and interoperable trauma and critical care registries would enable real-time situational awareness and postevent review.

Governance must reflect constitutional realities. Health delivery is provincial and territorial. Defence is federal. A viable framework requires codesign and shared federal–provincial funding agreements, recognizing fiscal constraints and building wherever possible on existing trauma and digital health infrastructure. Early steps should include convening a federal–provincial–territorial working group with Canadian Forces Health Services, Health Canada, the Public Health Agency of Canada, Canadian Blood Services, and Indigenous health authorities; designating pilot trauma hubs; standardizing memoranda of understanding for embedding and cross-credentialing; conducting joint national exercises; and publicly reporting indicators of readiness to respond to a conflict situation.

Ethical preparedness is inseparable from operational planning. Large-scale conflict introduces distributive dilemmas, including prioritization between military and civilian patients, allocation of scarce blood products and intensive care resources, and interprovincial redistribution under constraint. Standards of care to be met in a crisis must therefore be articulated prospectively and grounded in fairness, proportionality, transparency, and reciprocity to maintain public legitimacy under rationing conditions.¹² Clinicians require institutional support to mitigate moral distress associated with triage under scarcity. Given Canada’s geographic vulnerability and longstanding health inequities, engagement with northern and Indigenous communities is ethically imperative.

Canada has precedent for coordinated civilian–military medical governance. During World War II, federal authorities established mechanisms to balance military and civilian physician allocation and procurement at scale.¹³ The contemporary context is more complex, but the principle endures. National emergencies require coherent medical governance that transcends institutional silos.

In outlining how Canada’s health systems could be best prepared for conflict, we do not argue for militarizing health care but for structural coherence. Civilian hospitals will bear the clinical burden of sustained casualty events involving Canada’s people. Institutionalizing civilian–military medical integration now is a prudent investment in national resilience and the stability of Canadian health care.
