Canada's Arctic: A vast, vulnerable frontier
Spanning nearly 4 million square kilometres-an area larger than continental Europe-Canada's Arctic is a sparsely populated, high-risk region guarded by aging infrastructure and a skeleton crew of military and Coast Guard personnel.
With just 100 full-time Coast Guard members patrolling 162,000 km of coastline-60% of Canada's total oceanfront-and eight staffed military bases, the region's defences rely heavily on a network of early warning radars built for Cold War threats. Former Canadian Forces Northern Area commander Pierre Leblanc likened the environment to "extremely dangerous," where isolation and harsh conditions compound security challenges.
Geopolitical stakes heat up
The Arctic has become a focal point for global powers, bordered by Russia and the U.S. and increasingly eyed by China, which has expanded its icebreaker fleet and declared itself a "near Arctic state." Russia's 2022 invasion of Ukraine thrust Arctic security into the spotlight, while the Trump administration's renewed focus-including an executive order in April asserting U.S. dominance in Arctic waterways-has added urgency to Canada's efforts.
Prime Minister Mark Carney told the World Economic Forum in Davos that Canada is making "unprecedented" investments in radar systems, submarines, aircraft, and ground troops to secure "shared objectives of security and prosperity" in the region. Col. Leblanc, who spent nine years in the Arctic, called the spending hikes-from 2% to 5% of GDP by 2035-a "major shift," though he noted the push was partly driven by U.S. pressure.
Hypersonic threats outpace legacy defences
Experts warn that existing Arctic defences are ill-equipped for modern threats, particularly hypersonic missiles, which travel at five times the speed of sound and evade traditional radar. Troy Bouffard, director of the Center for Arctic Security and Resilience in Alaska, said current systems "cannot defend against hypersonic cruise missiles at all," citing Russia's operational use of the nuclear-capable Oreshnik missile in Ukraine.
"That technology has changed everything. We have to relook at the entire North American defence system and re-do it."

Over-the-horizon radar and space-based sensors-key components of the Trump administration's proposed "Golden Dome" missile defence system-are seen as critical upgrades, though Canada's role in the project remains unclear. Trump suggested at Davos that Canada should "be thankful" for the initiative, while later claiming on Truth Social that Ottawa opposed extending the dome over Greenland, prioritizing "doing business with China" instead.
Diplomatic tensions vs. on-the-ground cooperation
Despite heated rhetoric, including Trump's 2024 proposal that Canada either pay $61 billion to join the Golden Dome or become the 51st U.S. state, Arctic cooperation between the two nations persists. Canada's UN ambassador, Bob Rae, dismissed the statehood remark as a "protection racket," but experts say U.S. pressure has spurred Ottawa to act.
"Whether or not American concerns are justified, there is a feeling in Ottawa that we have to satisfy them. No one takes the 51st state issue seriously, but we do take the economic pressures seriously."

Bouffard emphasized that operational collaboration remains strong, with practitioners "rising above the rhetoric." However, logistical hurdles-such as limited port facilities and resupply challenges for remote bases-continue to hamper long-term security efforts.
What's next for Arctic security
Canada's defence upgrades, including enhanced radar and satellite networks, are expected to address some gaps, but the region's vastness and evolving threats demand sustained investment. The Golden Dome's fate-and Canada's role in it-will likely depend on diplomatic negotiations, though experts stress that Arctic security transcends political posturing.
As Bouffard put it: "Everyone's going to have to rise above the rhetoric."
