Canadian strategy when warming opens routes outside the archipelago

Policy research paper · 4 October 2026 - Author: Yunus Emre Tumen

Abstract

A warming Arctic could become substantially more navigable without making the Northwest Passage a principal intercontinental corridor. Models support selective bypass, especially for Europe–Asia shipping, while retaining Canadian route advantages for eastern North America. They do not establish central-ocean commercial dominance.¹ Canada should prepare through reliable continental defence, useful operating information, demonstrable logistics and response, and agreed roles in allied decisions. Northern governance must shape those capabilities. Transit-oriented investments require separate commercial evidence. Alaska and Greenland offer alternative American access, but the examined sources establish no Canada-bypass motive. Canadian influence should depend on demonstrable contributions and decision-making capacity alongside its maritime rights, rather than anticipated traffic.

The strategic significance of Arctic warming depends on where commercially useful routes emerge. If ships can increasingly cross the Central Arctic Ocean without entering the Northwest Passage, Canada could confront an unusual combination: greater activity in the wider Arctic, limited growth in Canadian through-transit, and continuing demands on continental defence and northern governance. The policy problem would concern the relationship between geographical access and Canadian influence, rather than a simple contest over how many foreign vessels enter the archipelago.

This possibility has a scholarly antecedent. Franklyn Griffiths argued in 2003 that direct Arctic Ocean crossings might eventually make large investments in a Northwest Passage seaway transitional or stranded. He nevertheless retained the case for disaster preparedness and Inuit participation.² The reversal of “use it or lose it” thus exposes an assumption worth testing: that the future importance of Canadian Arctic territory must derive substantially from other states needing to sail through it. Preparing for increased access is sensible. Equating that access with a commercially indispensable Canadian corridor requires further evidence.

That evidence supports selective bypass as a strategic planning scenario, with considerable uncertainty about its timing and scale. It does not demonstrate a Canadian commercial chokepoint monopoly that is now disappearing. Nor would low transit volumes make Canadian waters, northern communities, or continental defence less deserving of protection. Griffiths’s distinction between legal sovereignty and the practical freedom to make consequential decisions remains useful: secure title can coexist with dependence on externally supplied capital, expertise, or operating capacity.³

Canada should consequently assess Arctic investments by the missions they enable and the decisions they allow Canadians to shape. Its 2024 Arctic Foreign Policy already connects northern strategy with NORAD modernization, allied cooperation, infrastructure, and Indigenous partnership.⁴ Future business cases should demonstrate that essential capabilities remain justified under low Northwest Passage transit, while speculative commercial investments meet a more demanding evidentiary test. “Indispensability” should describe a contribution whose absence demonstrably impairs a shared mission. It cannot be inferred from an Arctic map or promised through procurement announcements.

The route hierarchy remains conditional

Comparative navigation models provide a credible physical basis for bypass. Smith and Stephenson’s mid-century September simulations identify transpolar opportunities for moderately ice-strengthened vessels travelling between Europe and Asia. Melia, Haines, and Hawkins likewise project a shift toward central routes for that trade as sea ice declines.⁵ An offshore corridor could avoid some coastal straits, accommodate deeper-draft vessels, and reduce exposure to Russian route regulation. Li and Lynch identify a possible western transpolar corridor north of the Canadian archipelago, approaching the Atlantic near Greenland.⁶ These are specific geographical possibilities, rather than proof that Canada will capture the commercial benefits of Arctic opening.

The same literature supplies strong contrary evidence. Smith and Stephenson retain the Northwest Passage as the optimal Arctic route for moderately ice-strengthened vessels between eastern North America and Asia in their mid-century simulations. Melia and colleagues also distinguish that trade from Europe–Asia shipping.⁷ Route preference therefore depends on origin and destination as well as climate and vessel capability. A transpolar corridor that dominates one market could coexist with Canadian transit niches. The phrase “the most important Arctic route” obscures this distinction unless importance is defined through actual cargo, network use, or military purpose.

Canada’s physical prospects also resist a single trajectory. Cook and colleagues find that mobile multiyear ice maintained chokepoints and shortened usable seasons along sections of the northern Passage during 2007–2021. Their findings expose the danger of extrapolating navigability from declining Arctic-wide ice cover.⁸ Yet Howell and colleagues document near ice-free conditions along the northern route at the end of September 2024, with the lowest ice area in records beginning in 1960.⁹ Both results matter. Regional seasonal hazards and an exceptional late-summer clearing concern different periods and measures; neither establishes permanent deterioration or dependable annual service.

Howell’s explanation strengthens this qualification. The authors attribute the 2024 clearing to rapid melt, reduced ice import, an extended melt season, and a less resilient initial ice cover occurring together. They anticipate continuing variability and difficulties predicting conditions months ahead.¹⁰ Mudryk and colleagues similarly project substantial gains in Canadian navigability at higher warming levels, while warning that coarse climate models inadequately capture local multiyear-ice advection. They explicitly consider a transpolar route becoming more attractive than the Passage, with fewer local commercial benefits and potentially less environmental and cultural disturbance.¹¹ Improved access and relative commercial disadvantage can therefore occur simultaneously.

Forecast disagreement has practical consequences. Wei and colleagues find major differences in transpolar opportunities across emissions pathways, models, and time periods. Their route frequencies represent optimized choices within simulations, rather than future market shares.¹² Stephenson and Smith’s earlier comparison restricts the Passage to its northern route because several climate models cannot resolve southern channels. That limitation can disadvantage Canadian alternatives in the comparison.³ The literature permits planning for central routes; it does not provide a defensible probability that they will dominate Arctic trade by a particular year.

Commercial viability introduces another set of conditions. A ship must encounter a usable route, complete a voyage with acceptable uncertainty, and earn sufficient revenue within an operating network. Container liners depend on schedules, intermediate cargo, return loads, fleet deployment, and port connections. Lasserre’s comparative review demonstrates how changing assumptions about these factors produces conflicting profitability findings.¹⁴ The distance advantage of a route can be absorbed by slower sailing, underutilized vessels, seasonal switching, or expensive recovery from delay. Conversely, individual seasonal voyages may be profitable without supporting a regular intercontinental service.

Cargo differences are decisive. Xu and Yin find potential annual savings for seasonal Northern Sea Route tramp shipping under particular icebreaking tariffs and operating conditions.¹⁵ Cariou and colleagues’ container analysis finds competitive westbound voyages but not eastbound ones in its business case, reflecting asymmetric utilization and ice-dependent timing.¹⁶ Lin and Chang’s network model selects the Northern Sea Route as a conditional complement under improved operating assumptions, while retaining established hubs.¹⁷ These disagreements reveal distinct business problems. They cannot be averaged into a single verdict on “Arctic shipping.”

Skepticism about coastal routes also has limits. Liu, Lian, and Yang’s fleet-and-network analysis finds Suez preferable in its baseline, but constrains Arctic vessels to relatively small sizes. The authors acknowledge that a deeper route north of the New Siberian Islands could accommodate much larger ships and would require a different cost analysis.¹⁸ A future central corridor might alter the economies of scale that currently favour established routes. Existing coastal Northern Sea Route models cannot settle the economics of that future configuration. The missing evidence is an integrated comparison of realistic route hazards, complete network costs, cargo commitments, and geopolitical access across the relevant alternatives.

Three planning cases follow. Destination-led growth could predominate, with resource transport and community supply driving activity while through-transit remains modest. A mixed system could add seasonal shortcuts, with transpolar services attractive for some Europe–Asia traffic and the Passage useful for eastern North American markets. A substantial central-ocean corridor could eventually become the principal Arctic through-route if reliable access, vessel scale, demand, and operating support align. These are scenarios derived from the evidence, not ranked forecasts. Each warrants different commercial infrastructure, while all retain Canadian requirements for territorial governance and continental defence.

The demanding case for Canadian strategy is the third. It tests whether policies justified by an anticipated national seaway would still work if that seaway remained commercially secondary. The answer should preserve the useful capabilities common to the other cases, rather than commit Canada to a single forecast. Such preparation also protects against the opposite error: abandoning a Canadian route that later proves commercially useful because central-ocean projections were treated as certainty.

Sovereignty and strategic consequence diverge

Three questions require separate answers: what rights Canada possesses, how effectively it exercises its responsibilities, and how much influence its contribution confers. Canada’s Arctic Foreign Policy reiterates its position that the Passage comprises internal waters. The Canada–United States Arctic Cooperation Agreement manages a specific operational disagreement by requiring Canadian consent for American icebreaker navigation in waters Canada claims as internal, while expressly preserving both countries’ legal positions.¹⁹ Cooperation has therefore been possible without a comprehensive jurisdictional settlement. A future bypass should not be treated as either a sovereignty concession or an opportunity to declare the dispute resolved.

Commercial necessity is also an unreliable legal test. Pharand’s analysis acknowledges that an international strait need not be the only available or essential route. The literature disputes the significance of actual and potential international use, alongside the validity of the underlying maritime claims.²⁰ Franckx’s recent reassessment questions Arctic straight baselines through a restrictive interpretation of customary-law criteria; it does not report a judicial determination against Canada.²¹ Reduced Passage traffic might lessen occasions for operational confrontation. That is a plausible political consequence, not a legal consequence mechanically produced by shipping elsewhere. Canada should maintain its position through lawful administration and diplomacy without manufacturing transit to substantiate it.

Climate-dependent pollution jurisdiction creates a different problem. Article 234 of the United Nations Convention on the Law of the Sea authorizes specified measures in ice-covered areas meeting stringent conditions, including ice coverage for most of the year. It requires nondiscrimination, due regard for navigation, and the best available scientific evidence. Scholarship disputes aspects of its spatial and temporal interpretation.²² Declining ice can consequently affect the justification for particular regulations even where traffic remains limited. Neither an ice-free summer nor a transpolar voyage automatically extinguishes Canadian title. Transport Canada should review measures grounded in Article 234 against changing local conditions, document their scientific rationale, and distinguish that authority from Canada’s other jurisdictional claims.

Strategic consequences can move independently of those legal questions. Under selective bypass, anticipated transit services and route-based bargaining opportunities might fail to materialize. Conversely, northern communities could face less through-traffic disturbance than under a major Passage corridor. Mudryk and colleagues explicitly recognize this combination of forgone opportunities and avoided impacts.²³ Canada would still require dependable community supply, environmental protection, surveillance, and defence. Those are public responsibilities with their own justification; commercial traffic should not become the admission price for meeting them.

The policy change is therefore to separate maritime rights from speculative commercial leverage. A port intended principally to serve foreign through-transit requires a different business case from facilities that sustain Canadian communities or a committed defence mission. Shared facilities may serve both, but each function needs an identifiable user, operating budget, and accountable decision-maker. Otherwise, anticipated international importance can conceal an unfunded domestic obligation or a commercial project whose customer has never been secured.

American access has several geographies

Alaska and Greenland make Canadian geographical indispensability a proposition to demonstrate. The United States’ 2024 Arctic Strategy places Alaska, Canada, and Greenland within the North American defence geography, while identifying Alaskan power projection, allied access, surveillance, and communications as operational priorities.²⁴ Simonsen Abildgaard and Gad trace earlier Greenland infrastructure to transatlantic aircraft movements and subsequent defence requirements.²⁵ These functions do not depend on commercial use of the Passage. The evidence establishes alternative operating opportunities; it does not establish that they reproduce every Canadian contribution.

Alaska provides an American position near the Pacific entrance to Arctic routes. However, the Bering Strait’s geography is shared with Russia, and its international navigation regime precludes treating the Alaskan shore as exclusive American control of Arctic entry.²⁶ Greenland offers opportunities on the Atlantic side and for northern warning and military access. A central-ocean route could increase the relevance of these positions relative to Canadian archipelagic transit, but coastal proximity alone would not establish a commercially competitive gateway. Cargo connections, facilities, operating costs, and reliable services would still matter.

The agreement signed by the United States, Denmark, and Greenland on 22 September 2026 reinforces the distinction between access and implementation. It provides for expanded defence opportunities at Pituffik and additional areas at Narsarsuaq and Mestersvig, subject to agreed details, while reaffirming sovereignty and self-determination. Entry into force requires completion of the stipulated domestic and diplomatic procedures. The signed text demonstrates willingness to expand access; it does not demonstrate completed new bases, profitable shipping hubs, or a purpose of bypassing Canada.²⁷

Greenland is consequently an actor whose decisions matter. Rahbek-Clemmensen’s study shows how Greenlandic authorities have exercised contingent influence through legal, political, and normative bargaining over defence arrangements. Its cases precede the new agreement and cannot explain that agreement’s motives.²⁸ Canadian diplomacy should approach Greenlandic and Danish institutions as negotiating partners, including on infrastructure benefits and operational cooperation, rather than treat Greenland as territory available at another state’s unilateral discretion. Geography creates possibilities that political agreement must make usable.

The strongest defensible inference is limited substitution: American and allied alternatives could reduce reliance on particular Canadian services. The reviewed evidence does not quantify the extent of substitution across continental warning, logistics, or maritime response. Nor does it support the hypothesis that American interest in Greenland exists in order to bypass Canada. Existing defence purposes explain much of the relevant infrastructure without that additional motive. Canada should test substitution mission by mission, asking whether alternatives offer equivalent coverage, access, endurance, and decision speed at an acceptable cost.

This approach avoids making Canadian strategy dependent on proving someone else’s intentions. If an American or Greenlandic facility provides a service more efficiently, duplicating it solely to secure a Canadian flag would be a poor investment. If Canadian participation closes a demonstrated gap or improves resilience, that contribution should be documented and incorporated into shared planning. Influence would then rest on an agreed operational role whose value can be evaluated, alongside the sovereign choices Canada retains over its own territory.

Contribute where Canada improves allied operations

Canada should prioritize three contributions: continental defence, usable operating information, and credible logistics and response. Their value extends across all three shipping scenarios, although their scale and location should vary with demand. The practical objective is to reduce a partner’s or Canadian operator’s demonstrable vulnerability while retaining the capacity to make consequential decisions. Claims of uniqueness require comparison with alternatives. Useful Canadian services can remain substitutable; policy must earn influence through performance and negotiated participation rather than assume that service provision automatically creates leverage.

Commercial bypass could coexist with serious military threats. Defence requirements must therefore be assessed independently of commercial route choice. The information and response portfolio proposed here supplements that defence floor; shipping volumes cannot determine the forces needed to protect Canada.

Continental defence has the clearest strategic justification independent of trade. NORAD’s missions comprise aerospace warning, aerospace control, and maritime warning. Maritime warning should not be described as a general mandate to control Arctic shipping.²⁹ Canada’s Arctic Over-the-Horizon Radar programme moved into delivery arrangements in June 2026, with initial capability anticipated in December 2029. Its purpose concerns airborne threats.³⁰ Delivering and integrating that capability matters even if no commercial vessel chooses the Passage. It does not, by itself, provide identification and tracking of surface ships or submarines.

The Department of National Defence should therefore specify which operational gaps each investment addresses, the information it must deliver, and the forces able to act on that information. Air surveillance, maritime awareness, and underwater requirements need distinct assessments within a coherent continental plan. Solomon and Fetterly show how burden-sharing conclusions change when analysts value Canadian geography and installations differently.³¹ Their analysis supports examining contributions beyond expenditure totals, while supplying no proof that a particular Canadian asset is irreplaceable. Performance assessment should focus on delivered coverage, validated information, usable warning time, and sustained readiness; procurement spending alone cannot establish any of these outcomes.

Maritime information offers a second contribution, but its comparative advantage must also be tested. Johnson’s analysis connects environmental observations, sensors, community knowledge, communications, and human interpretation while identifying institutional obstacles to integration.³² Canada should connect Canadian Ice Service products, civilian vessel information, and defence assessments where mandates and permissions allow. The objective would be an operational picture that helps a named user make a timely decision, with clear responsibility for uncertainty, restricted information, and system failure. Producing more data is insufficient if operators cannot obtain, interpret, or lawfully share it.

The corpus provides a concrete starting point. Holloway and colleagues identify demands for frequently updated, clearly timestamped information, delivery compatible with limited bandwidth, and training in interpretation. Their survey includes commercial and non-commercial vessel operators but excludes local community boating and does not represent Inuit governance.³³ Müller and colleagues identify the importance of timely multihazard information alongside ship capability and regulatory compliance.³⁴ Improvements should be tested with actual users under disrupted communications, rather than demonstrated only through well-connected headquarters. For central-ocean operations, Canadian agencies should establish where their observations improve forecasts or decisions beyond services already available from partners.

Longer-term prediction remains a research problem. Melia and colleagues identify ice-thickness initialization as important to potential seasonal route-prediction skill, using a perfect-model experiment.³⁵ That supports investment in observations and model evaluation, rather than a claim that Canada can already offer dependable seasonal routing. Environment and Climate Change Canada should assess forecast performance against observed conditions and communicate limits in terms operators can use. Better information could make Canada a valued contributor outside its waters; demonstrated operational uptake and improved decisions must precede claims of indispensability.

Logistics and response provide the third contribution. The Northern Operational Support Hubs programme already plans a distributed network with materiel, maintenance, medical support, and partnerships.³⁶ Canada should evaluate its delivery against named missions: aircraft turnaround, deployable maintenance, communications continuity, fuel availability, evacuation arrangements, and sustained operation during disruption. Additional central-ocean support facilities should follow demonstrated gaps and partner commitments. A hub without personnel, recurrent funding, transport connections, and exercises cannot establish the contribution its location appears to promise.

There is already evidence of Canadian support beyond Passage transit. Canada’s Arctic Foreign Policy identifies Operation Pacer Goose’s resupply of Pituffik, and the Coast Guard’s 2026 season announcement records the departure of a vessel assigned to that mission.³⁷ This demonstrates a practical allied contribution, while leaving its replaceability unmeasured. It offers a better starting point than an abstract promise to become the indispensable supplier of the entire Central Arctic Ocean. Canadian and partner planners should examine what expanded tasks are feasible, who would fund them, and what continuity arrangements protect Canadian domestic missions.

A bounded first test could combine validated Canadian ice and weather products, support from existing Canadian facilities where range permits, and agreed data and planning roles for a joint summer mission approaching the projected western transpolar corridor. Compare the operation with and without that package against the best Alaskan and Greenlandic alternatives. A demonstrated gain in endurance or reduction in an information gap would justify negotiating a sustained contribution and Canadian participation in mission decisions. An unsuccessful test would argue against expansion. This would test a particular contribution, rather than promise a Canadian hub for every offshore voyage.

Fleet choices must follow those tasks. Lajeunesse’s account identifies the Arctic and Offshore Patrol Ships as platforms for access, awareness, logistics, and support across government. It also explains why ships do not resolve the legal disagreement with the United States.³⁸ Their utility should not be converted into an assumption of heavy icebreaking or high-intensity combat capability. Following its transfer to National Defence, the Coast Guard remains civilian; its expanded security-information role does not confer law-enforcement powers.³⁹ Assessments should compare patrol ships, icebreakers, aircraft, and other capabilities against explicit tasks and operating conditions before choosing a fleet mix.

Search and rescue demands particular restraint. The 2011 Arctic agreement allocates responsibilities without prejudicing sovereignty or maritime boundaries; it does not guarantee that Canada alone can rescue every vessel throughout its assigned region. Sydnes and colleagues distinguish cooperative arrangements from operational readiness, while Østhagen identifies the limits of pooling scarce coastguard resources across large distances.⁴⁰ Canada should exercise clearance procedures, communications, available platforms, fuel, and medical transfer with neighbouring partners, including demanding offshore cases. Those exercises should establish realistic response limits and guide prevention. Rescue responsibility is neither a territorial claim nor evidence of unlimited rescue capacity.

Operational cooperation should also secure a Canadian role in decisions. Global Affairs Canada and National Defence should negotiate planning participation, relevant data access, command relationships, and procedures for disagreements alongside any expanded support commitments. That is a policy recommendation, not an outcome guaranteed by the literature. Canada should avoid exchanging essential maritime rights for promises of relevance or constructing artificial dependencies. A consequential role requires sufficient Canadian capacity to honour commitments, evaluate partners’ proposals, and influence the missions its capabilities support.

Northern authority is part of strategic capacity

Bypass changes neither northern rights nor the legitimacy requirements of Canadian policy. Greaves’s analysis identifies environmental security, cultural continuity, and political autonomy among Indigenous security concerns, challenging approaches that subordinate them to state territorial narratives.⁴¹ Northern residents should not be asked to justify public investment by demonstrating their usefulness to a national sovereignty claim. Community supply and safety remain obligations even where there is no plausible transit market. Strategic contribution should be built through governing relationships that northerners can shape.

Icebreaking makes this principle operational. Bishop and colleagues show how icebreaking can support resupply while disrupting sea ice used for travel and harvesting. Their policy review identifies weak operational protection of Inuit concerns in several instruments and proposes substantive governing roles.⁴² Improved navigability therefore does not simply release a maritime asset for unrestricted use. A Canadian service intended to support central-ocean shipping could impose costs on people whose own movements depend on ice. Those costs belong in the mission and investment assessment.

The Canadian response should include funded participation by relevant rights holders in operating protocols, seasonal constraints, two-way voyage notices, and emergency procedures. The precise allocation of authority must respect applicable agreements and institutions; a generic promise of consultation cannot substitute for those arrangements. Operators need clear rules about who decides, how urgent safety exceptions work, and how affected communities obtain explanations and remedies. Indigenous knowledge should enter through agreed governance of collection, interpretation, access, and reuse, with resources for the institutions undertaking that work.

This would deepen commitments Canada already makes. The 2024 Arctic Foreign Policy recognizes rights, self-government, and Indigenous demands to participate as partners beyond consultation.⁴³ For defence infrastructure, those commitments should have budgetary and operational consequences: negotiated local benefits, funded training and maintenance roles, accessible services where appropriate, and protection against transferring recurrent costs to under-resourced communities. Dual-use facilities require agreement on when military demands take priority and how competing civilian needs are accommodated.

Infrastructure literature also warns against equating construction promises with community benefit. Povoroznyuk’s comparative port research identifies projects sustained by ambitious expectations despite weak implementation and local costs. Simonsen Abildgaard and Gad likewise show that connections can reproduce dependence as well as enable autonomy.⁴⁴ These cases do not predict failure of Canadian projects. They support requiring credible operations, locally assessed benefits, and transparent responsibilities before expansion. Such governance can improve continuity and legitimacy, although the corpus does not quantify a causal readiness dividend. It is a substantive condition of Canadian authority, not merely a device for making defence investments easier to approve.

Preserve options and attach commitments to evidence

Implementation should begin with a distinction between assured responsibilities and contingent opportunities. National Defence and the Coast Guard should prioritize staffing, maintenance, communications, and usable access for committed Canadian and continental missions. Global Affairs Canada should align expanded international undertakings with that deliverable capacity. Core services should be assessed under limited-transit conditions so that their justification survives commercial bypass. Under this criterion, a facility can be essential even if it earns no transit revenue; another can be commercially attractive without becoming a national defence priority.

The next commitment should be modest, testable improvements to information and response. Agencies should identify users, partners, costs, delivery dates, and measures of operational effect before expanding coverage. A central-ocean initiative should establish the gap it addresses and compare Canadian provision with Alaskan, Greenlandic, and other allied alternatives. Exercises and forecast evaluations should test the proposal; operating agreements should establish Canadian participation and responsibilities. Additional hubs or extensive offshore commitments should follow that evidence, rather than precede it in anticipation of influence.

Commercial expansion warrants a later and separate decision. Transport Canada should require route-specific evidence of repeated voyages, cargo commitments, viable return loads, schedule performance, insurance and operating costs, and continuing demand before public investment in transit-oriented facilities. A commercial proponent should explain why established southern connections or an alternative Arctic gateway cannot meet the need more effectively. The corpus provides no validated universal threshold for approving such projects. Canada should set project-specific conditions transparently and include the costs of readiness, environmental protection, and community impacts in the assessment.

Environmental claims need comparable discipline. Lindstad, Bright, and Strømman show that reduced voyage distance and carbon dioxide emissions need not translate into a lower overall climate impact when short-lived pollutants and Arctic effects are considered. Their results depend on technologies and evaluation periods.⁴⁵ “Shorter” should therefore not become a general synonym for “greener.” Project appraisal should identify relevant emissions, local effects, uncertainty, and applicable regulation rather than credit distance savings alone. Low transit demand may leave Canada with fewer commercial opportunities while avoiding some associated costs.

An annual review should draw together separate departmental accounts: National Defence for readiness, Transport Canada for commercial investment evidence, Global Affairs for international commitments, and Environment and Climate Change Canada for forecast performance. Northern governing partners should shape criteria and findings affecting their jurisdictions. Each responsible minister should explain whether the evidence supports continuing, redesigning, or deferring the next expansion tranche. Reviews should distinguish seasonal ice anomalies from repeatable service and assistance supplied from influence secured. Publish reasons while protecting sensitive operational detail. Essential domestic services should continue without awaiting commercial validation. This proposed mechanism connects evidence to decisions rather than creating another committee.

The Northwest Passage should remain an option within that process. Maintain the charting, information, safe access, and domestic infrastructure justified by actual users, while preserving the ability to scale services if eastern North American transit becomes viable. Reassess central-ocean commitments as routes and demand develop. If bypass occurs, Canada should remain consequential through capabilities that work, rights that it can administer, and decisions in which it participates. If it does not, the same foundation would leave Canada better prepared for traffic through its waters. Arctic influence would rest on delivered responsibility and agreed contribution, with commercial geography informing strategy rather than determining it.
