THE CAF’S SUPPLY CHAIN CHALLENGE: PT 2

THOUGHT LEADERSHIP

The Capacity / Demand Balance

BY ALLAN McDOUGALL & DAN DORAN

This Op-Ed is the second in a three-part series examining how to address critical supply chain challenges that directly impact the Canadian Armed Forces’ operational effectiveness and national security interests.

Equipping soldiers, sailors, or aircrew requires ensuring that tools, assets, and supplies arrive where they are needed, on time, in acceptable condition, and at a reasonable cost. When these criteria aren’t met, it’s not just a supply chain failure — it creates serious consequences for those on the front lines defending Canada’s sovereignty and protecting its interests.

When we talk about security, we often focus on protecting critical infrastructure — and for good reason. Critical infrastructure underpins national security and sovereignty, enables government functions, military operations, emergency services, and communications. If compromised, a nation’s ability to respond to threats or project power diminishes. It also anchors economic stability: power grids, financial networks, transportation, and telecommunications form the backbone of the economy. A disruption can lead to cascading failures and paralyze supply chains. Finally, it protects public safety through water treatment plants, healthcare systems, emergency services, and food supply chains. Disruptions in these sectors can quickly undermine national resilience.

All three of these domains are interconnected by a single driving requirement: resilience. Resilience is the capacity for critical infrastructure to withstand, adapt to, and recover from disruptions — whether from cyberattacks, physical threats, natural disasters, or geopolitical conflict.

Vulnerabilities within critical supply chains pose similar risks to national sovereignty and security. These vulnerabilities must be balanced against high consumer demand and price sensitivity. As a result, critical supply chains need to maintain equilibrium between the demands placed on them and their capacity to meet those demands. This brings us back to the fundamental requirement that resources arrive where they are needed — extending beyond military logistics to all critical infrastructure. It’s not enough to achieve mathematical balance; supply and demand must align geographically and operationally to create a workable system.

HOW DO WE MANAGE THAT BALANCE?

We need to source what is required and ensure it gets where it is needed. We can do this with ultra-efficiency — sending just enough supply to meet demand. While efficient from a control perspective, this leaves no slack in the system if something goes wrong. It makes the entire supply chain highly vulnerable to shocks when even a single element fails.

Compounding this vulnerability is the fact that we operate in a world far from stable. There are actors actively seeking to disrupt our systems. We cannot assume our infrastructure will remain untouched. Without built-in resilience or redundancy, systems are likely to fail us when we need them most.

In the communications domain, we encounter a similar dilemma. Do we send a single message through a reliable, secured route like Transmission Control Protocol (TCP), or do we send multiple messages through different routes, trusting that the full message will eventually be received via User Datagram Protocol (UDP)?

The TCP route is more efficient in handling the volume of material but can become a single point of failure if an adversary finds a way to disrupt it. The UDP approach is less efficient, but its strength lies in the assumption that an adversary cannot identify and block all routes. Enough messages will get through. This UDP approach to communication resilience applies equally to supply security — whether securing rail networks transporting tanks or designing hydro-electric distribution grids.

JUST IN TIME
VS. JUST IN CASE

Ultimately, this boils down to two competing supply chain philosophies: “just in time” versus “just in case.” The “just in time” model uses transportation systems as virtual warehouses. Though mathematically efficient, its perfection cannot withstand real-world disruptions. When shipments are delayed, cancelled, or damaged, the process collapses due to a lack of inputs. The “just in case” model blends elements of “just in time” with more traditional stockpiling. Here, facilities maintain adequate reserves to adjust supply chains or resolve issues without halting operations. This allows continued production despite disruptions. It also enables replenishment through contractual clauses that ensure stockpiles are restored and ready for future disruptions.

In an increasingly unpredictable world, managing the balance between supply and demand requires a deliberate shift from purely efficient systems to those built for resilience. Whether moving tanks, transmitting data, or opening strategic infrastructure in the North, success hinges on designing networks that can adapt, absorb shocks, and continue operating under stress.

In the end, resilience isn’t just a feature — it’s the foundation.
