When a diesel resupply convoy fails to reach a northern Canadian base, delayed by weather or some other supply chain error, the consequences can be enormous. In a part of the world growing more contested every day, an interrupted power supply is a vulnerability that our adversaries notice and, given the opportunity, will exploit.

Canada’s Arctic sovereignty depends on persistent, capable presence. That presence, across too many of our northern installations, still runs on diesel generators, fuel convoys, and the naive assumption that the supply chain will hold. At a moment when Canada is committing to a generational rebuild of its northern defence strategy, the foundational question of how we power our defensive capabilities demands a serious and urgent answer.

That answer is strategically deployable power. Nuclear microreactors to be more specific. Unlike large-scale nuclear installations, microreactors designed for specialty deployment are portable, modular, and engineered for extreme isolation. They are designed to power the places that the grid cannot reach, such as remote military installations, forward operating bases and northern communities that currently burn diesel at an enormous financial and........
