The global economy now runs on digital systems. It’s no surprise, then, that national sovereignty increasingly depends on the strength and security of that infrastructure. Governments should treat digital networks with the same seriousness as water, transportation, and energy systems; core assets that underpin economic stability and public trust.
A clear-eyed assessment of IT risk is the first step. This should be focused on exposure both within organizations and across supply chains. Understanding where systems are exposed helps identify blind spots and prioritize investments in security and resilience before vulnerabilities become liabilities. Below are some key takeaways from a defence and national security perspective.
To maintain digital sovereignty, Canada doesn’t need to compete with or withdraw from the global technology market. Instead, we must maintain control where mission assurance depends on it. For Canada’s defence ecosystem, digital capabilities now underpin nearly every major operational platform. The same interconnected systems that enable speed and innovation also introduce exposure through complex, globally distributed supply chains.
The issue is not whether dependency exists. The critical question is where and if dependency becomes vulnerability. Which systems and subsystems demand sovereign control? Where is allied reliance acceptable? And how much visibility do you truly have and need across your digital stack?
The choices made today in procurement, architecture, and partnerships will shape Canada’s operational resilience for many years.
From a defence standpoint, nearly all upcoming major capital investments will have a significant digital foundation to them. Moreover, those capital investments will need to be integrated with a constantly evolving defence digital foundation. Modern defence systems, communications, surveillance, logistics, weapons platforms, or otherwise, rely heavily on advanced digital infrastructure and interconnected IT systems. The security and resilience of these digital assets are therefore directly linked these platforms’ performance and to national security.
Treat digital as mission-critical infrastructure
Apply the same discipline to protect digital platforms as is used to protect physical assets. Conduct mission-aligned risk assessments across command-and-control, intelligence, logistics, and weapons systems. Identify single points of failure, foreign dependencies, and operational technology exposure. If a system underpins readiness or personnel safety, it warrants operational security, as well as critical infrastructure–level governance, monitoring, and protection.
Map risk and secure sovereign supply chains
Develop deep supply chain transparency across hardware, software, cloud, and managed services. Identify where foreign control, offshore hosting, or embedded third-party code introduces risk. Prioritize Canadian-based capabilities, cleared talent, and trusted partnerships to reduce risk exposure, while maintaining interoperability with allies.
Build sovereign-by-design into investments
Embed sovereignty requirements at procurement and design stages as major capital programs becoming increasingly digital at their core. Define clear data residency standards, cyber resilience benchmarks, and lifecycle accountability from acquisition through sustainment. Invest in domestic cyber, AI, and advanced communications capabilities to ensure Canada retains strategic control over the systems it relies on most. This is both a procurement strategy issue and an in-service support strategy issue.
Digital sovereignty is no longer a policy issue or debate. For Canada’s defence ecosystem, it is a readiness imperative.
