Canada Arrives at RIMPAC 2025 With a Message for Washington
In a move analysts are reading as both military signaling and political messaging, Canada has deployed two frigates and a submarine to the world's largest multinational naval exercise. HMCS Ottawa, HMCS Regina, and submarine HMCS Corner Brook are participating in the biennial Rim of the Pacific Exercise — known as RIMPAC — running from late June through July 31, 2025. The exercise is expected to draw more than 25,000 military personnel from 31 nations, including Australia, Japan, and the United States. For Ottawa, the deployment is more than a routine show of naval strength. It is, according to defense analysts, a calculated rebuttal to a persistent and politically charged accusation from Washington: that Canada is a freeloader on Western security.
What Is RIMPAC and Why Does It Matter?
The Rim of the Pacific Exercise is the largest international maritime warfare exercise in the world, held biennially off the coast of Hawaii. It brings together naval forces from across the Pacific Rim and beyond to train in a wide range of operations, including surface warfare, submarine exercises, humanitarian assistance, and expeditionary logistics. Participation in RIMPAC carries both strategic and symbolic weight. Nations that show up with capable, deployable assets signal to allies and adversaries alike that they are serious contributors to the rules-based international order, not passive beneficiaries of it.
For Canada, whose naval contribution this year includes a submarine — a relatively rare and operationally complex asset — the message is deliberate. Submarines require specialized training, sustained investment, and long logistical tails. Sending HMCS Corner Brook alongside two Halifax-class frigates demonstrates a layered, multi-domain naval capability that goes beyond token participation.
The Freeriding Accusation: Where It Comes From
The charge that Canada benefits from American security guarantees without paying its fair share has been a fixture of U.S.-Canada relations for years, but it sharpened dramatically under President Donald Trump. Trump has consistently singled out NATO allies, including Canada, for spending below the alliance's two-percent-of-GDP defense target. Canada has historically hovered around 1.3 to 1.4 percent, a gap that Washington has used as evidence of freeriding — the idea that Ottawa enjoys the umbrella of U.S. military deterrence without contributing adequately to its upkeep.
The criticism gained particular political urgency following Trump's return to the White House and his broader rhetoric about reassessing American commitments to allies perceived as insufficiently serious about their own defense. For Canada, which shares the world's longest undefended border with the United States and depends heavily on bilateral trade and security cooperation, the freeriding label carries real diplomatic and economic consequences. Dismissing it is not an option Ottawa can afford.
How RIMPAC Fits Into Canada's Broader Defense Pivot
Canada's deployment to RIMPAC 2025 does not exist in isolation. It is part of a wider pattern of defense signaling that Ottawa has been amplifying in recent months. The Canadian government has announced plans to reach the two-percent NATO spending target, pledged increased investment in Arctic sovereignty and surveillance, and stepped up its rhetoric around Indo-Pacific engagement. The 2022 Indo-Pacific Strategy committed Canada to a more active role in regional security, and RIMPAC participation is one of the most visible ways to demonstrate that commitment to both Pacific partners and skeptical American officials.
Analysts note that sending a submarine is particularly significant in the Indo-Pacific context. Undersea warfare is at the heart of strategic competition in the region, and nations that can operate submarines credibly are taken more seriously at the planning table. Canada's Victoria-class submarines have had a troubled history marked by maintenance delays and limited operational availability, which makes deploying HMCS Corner Brook to a high-profile multinational exercise a meaningful statement about where the Royal Canadian Navy's priorities lie.
What Allies and Analysts Are Saying
Defense analysts watching the RIMPAC deployment describe it as well-timed and strategically coherent. Canada is not simply showing up — it is showing up with assets that matter. The combination of surface combatants and a submarine reflects a genuine multi-domain naval contribution rather than a symbolic gesture. For Indo-Pacific partners like Japan and Australia, who are deepening their own security architectures in response to Chinese naval expansion, Canada's presence reinforces the message that Western commitment to the region is broad and not exclusively American.
At the same time, observers caution that military exercises alone will not resolve the underlying tension over defense spending. Washington's freeriding critique is fundamentally a fiscal and political argument, and it will require sustained budget increases and credible procurement timelines — not just high-visibility deployments — to put it to rest definitively. Canada's announced path to two percent spending will be watched closely by American officials for concrete follow-through.
The Stakes for Canada-U.S. Defense Relations
The RIMPAC deployment comes at a moment when Canada-U.S. relations are navigating genuine strain. Trade tensions, sovereignty disputes over Arctic waters, and the persistent defense-spending friction have created an environment in which symbolic gestures carry real political weight. For Ottawa, participating visibly and substantively in RIMPAC is a way of countering the freeriding narrative with action rather than argument.
Whether it moves the needle in Washington depends partly on how the Trump administration chooses to interpret it. But for Canada's Indo-Pacific partners and for the broader alliance architecture that Ottawa depends on, the message sent by HMCS Ottawa, HMCS Regina, and HMCS Corner Brook steaming toward Pearl Harbor is clear: Canada intends to be counted.
Conclusion: Deployment as Diplomacy
Canada's RIMPAC 2025 deployment illustrates how military exercises have become instruments of political communication in an era of alliance stress. By committing two frigates and a submarine to the world's largest naval exercise, Ottawa is doing more than training alongside allies — it is actively contesting a narrative that threatens its relationship with its most important security partner. The ships and sailors represent Canada's answer to the freeriding charge, delivered not in words but in wake.
