Canada must secure its undersea lifelines

In an era where global security threats are evolving in unexpected ways, a chilling new frontier has emerged: the battle beneath the waves.

Undersea communication cables—the hidden arteries that carry more than 95 per cent of the world’s data—have become prime targets in geopolitical competition. These cables underpin everything from financial transactions to government communications and military operations, making them critical to modern society’s function. But, as recent attacks have demonstrated, they are alarmingly vulnerable.

Consider the intentional severing of communication cables near Taiwan last year, reportedly by Chinese vessels. The act disrupted internet access for entire communities, and highlighted the ease with which vital infrastructure could be sabotaged. The incident was a stark warning to nations like Canada, whose undersea cables form a lifeline for its economy, national security, and connection to allies. If Canada fails to act decisively to protect this infrastructure, the consequences could be devastating, not only for the country, but also for the broader global order it supports.
