About this episode
The episode discusses the future of Arctic connectivity and the strategic importance of subsea infrastructure in the context of evolving security challenges.
In this episode, we sit down with Alex Dalziel, Senior Fellow at the Montreal Institute for Global Security, to discuss the future of subsea connectivity and the strategic importance of Arctic infrastructure in an evolving security landscape. Alex explores how hybrid threats and grey-zone tactics complicate the protection of subsea cables, particularly in regions shaped by climate change, increased economic activity, and geopolitical rivalry. He also examines the challenges of attribution when disruptions occur, and what resilience looks like in practice when designing infrastructure for contested environments. Finally, we discuss the role Canada can play in shaping Arctic connectivity and why a whole-of-society approach is essential for protecting critical infrastructure in remote regions.
