ANALYSIS: Canada-Australia Sign a $2.5-Billion Arctic Radar Deal

Introduction: Canberra, June 22, 2026 — the day Canada's North began to see farther

A signature in Australia to defend the Canadian Arctic

On June 22, 2026, in Canberra, Canada's Secretary of State for Defence Procurement, the Honourable Stephen Fuhr, signed a government-to-government agreement with Australia's Deputy Prime Minister and Minister of Defence, the Honourable Richard Marles. The subject of this agreement: a contract worth $2.5 billion Canadian for the acquisition of an Arctic over-the-horizon radar system — the A-OTHR (Arctic Over-the-Horizon Radar) program — whose technology is based on Australia's JORN network (Jindalee Operational Radar Network), forty years of expertise in long-range radar detection. BAE Systems Australia is the production contractor. Construction begins July 1, 2026. Initial operating capability is scheduled for December 2029. Full capability — the entire A-OTHR program in its final configuration — is expected in the 2035-2043 window. This is not an announcement. It is a transformation of the North American surveillance architecture. It is the moment Canada stops being blind in its own northern approaches.

Three legal instruments for a complete technology transfer

The agreement of June 22, 2026 marks the A-OTHR program's transition into its delivery phase. It comprises three distinct legal instruments: the government-to-government acquisition arrangement itself, an OTHR rights agreement concluded between Canada, Australia and BAE Systems Australia, and a comprehensive industrial and technological benefits agreement with BAE Systems Australia. This contractual triad is not accidental. It reveals the partnership's sophistication: Canada is not merely buying a radar system. It is buying a technology transfer, intellectual property rights on the system, and concrete commitments of industrial spinoffs on Canadian soil. The A-OTHR program is estimated to generate approximately $290 million per year in contribution to Canadian GDP and support approximately 2,270 jobs per year in the Canadian economy during the period from 2026 to 2033. This is not just defence. It is industrial policy dressed as national security — and both objectives are perfectly legitimate.

OTHR technology: seeing beyond the horizon by bending the gaze

The physics of the ionosphere in service of continental defence

The fundamental principle of over-the-horizon radar (OTHR) rests on a precise physical phenomenon: the refraction of radio waves in the ionosphere. Conventional radars send signals in a straight line — and that straight line follows the curvature of the Earth. Beyond a certain distance (typically 300 to 500 kilometres for conventional radars at sea level), the Earth's curvature means the signal passes over the target. Aircraft, missiles and ships beyond that horizon remain invisible. Over-the-horizon radar circumvents this fundamental limitation by sending its signals upward, toward the ionospheric layer of the atmosphere at 90 to 300 kilometres altitude, where high-frequency waves are refracted (bent) and returned toward the Earth's surface at distances potentially reaching 1,000 to 3,000 kilometres. In practice, this means the Canadian A-OTHR system will be able to detect aircraft, cruise missiles, drones and surface vessels at distances no conventional radar can reach from Canadian soil.

Canada's northern approaches — the blind spot of continental defence

The operational reach of the A-OTHR system is particularly critical in the Arctic context. Canada's northern approaches — the Canadian Arctic Archipelago, Davis Strait, Baffin Sea, accesses from the Beaufort Sea and the Northwest Passage — cover millions of square kilometres of maritime and aerial territory essentially unmonitored in the current configuration. The North Warning System, which constitutes the current first detection screen, dates from the Cold War and is designed primarily to detect high-altitude bombers — not modern low-flying cruise missiles, not hypersonic ballistic missiles, not long-range drones. The configuration of the A-OTHR program according to the True North Strategic Review document of June 22, 2026 plans coverage of the central and eastern part of the country, up to the Davis Strait zone and the southern tip of Greenland — precisely the most vulnerable approaches in the context of the current Russian military posture.

The Australian JORN: forty years of experience as a technological guarantee

The Jindalee network, the world's uncontested OTHR reference

The Australian Jindalee Operational Radar Network is not an experimental project. It is an operational system, deployed, proven and maintained for decades over a continental territory with geographical challenges presenting several analogies with the Canadian Arctic: vast, sparsely populated, difficult to access, exposed to aerial and maritime approaches over very long distances. JORN comprises three radar sites distributed across Australian territory — at Longreach (Queensland), Laverton (Western Australia) and Alice Springs (Northern Territory) — which together cover approximately 37,000 kilometres of Australian coastline with a surveillance depth of up to 3,000 kilometres at sea. BAE Systems Australia is the company that developed and maintains this system since its origins in the original Jindalee project of the 1970s. It is currently undertaking a major mid-life upgrade of JORN under the AIR2025 Phase 6 project.

The necessary adaptation to Canadian Arctic conditions

For Canada, choosing the Australian JORN technology as the basis for the A-OTHR program is not an arbitrary decision. It is a decision based on a decade of technical evaluation. According to information published by True North Strategic Review, the Australian Defence Science and Technology Group worked with Canada from August 2025 onward to establish the mission requirements for the Arctic A-OTHR system, which will be substantially larger than a JORN site. This difference in scale is important: the Canadian Arctic presents distinct ionospheric atmospheric conditions from Australia — more extreme temperatures, different ionospheric behaviour across seasons, interferences linked to auroral activity. JORN technology must be adapted, not simply copied. That is precisely why Defence Research and Development Canada (DRDC) is involved in the technology development collaboration with Australian partners.

The program's physical sites: Ontario as the first step, the Arctic as the horizon

Kawartha Lakes and Clearview Township — where everything begins

Why Ontario — the technical logic behind a counter-intuitive geographic choice

The physical architecture of the A-OTHR program is more complex than most government announcements let on. According to detailed data published by True North Strategic Review on June 22, 2026, this is Phase 1 of the project — not the final configuration. The first two radar sites will be located in Ontario: a permanent transmitter site on a 163-hectare property in the City of Kawartha Lakes, and a preliminary receiver site on a 288-hectare property in Clearview Township. In total, the future configuration of the A-OTHR system will require more than 1,500 hectares located south of the 46th parallel. The Phase 1 construction team is a partnership between Aecon, Pomerleau and Stantec — a civil engineering consortium announced in March 2026 and formalized in an integrated project delivery agreement with Defence Construction Canada.

The fact that the first sites are in Ontario — south of the 46th parallel — is surprising at first glance for a system named "Arctic" radar. But the technical logic is coherent: ionospheric refraction allows an over-the-horizon radar to interrogate geographically very distant zones from its physical site. A transmitter system in Ontario can effectively monitor the continent's northern approaches at distances of 1,000 to 3,000 kilometres by pointing its signal northward. This approach also allows construction on existing infrastructure, access to significant electrical capacity available in the Ontario grid, and reduction of the considerable logistical costs of building directly in the Arctic. The later phases of the program — whose details remain under development according to True North Strategic Review — plan an expansion toward other sites that will deepen the system's coverage and redundancy.

The A-OTHR program within the global continental defence architecture

NORAD, NorthWatch, NASS — the layers of an integrated detection system

The A-OTHR program does not operate in isolation. It fits within a continental defence architecture under reconstruction that includes several complementary programs. According to the detailed analysis of True North Strategic Review, the A-OTHR forms the inner layer of a larger network called the Northern Approaches Surveillance System (NASS) — covering the northern and eastern approaches to the continent, up to the Davis Strait zone and the southern tip of Greenland. This inner layer is complemented by the Polar Over-the-Horizon Radar (P-OTHR) — a separate system that will cover the even more northerly approaches, including the Arctic Archipelago and the Arctic Ocean. The combined initiative of these two systems is called NorthWatch. It forms the radar backbone of Canada in its northern approaches — a defence in depth that simply did not exist before.

Canadian leadership in NORAD — a first in sixty-eight years

The A-OTHR program is also the first major capability development program that Canada leads within the binational NORAD command. This is a notable fact in the history of the Canada-US defence relationship: since NORAD's creation in 1957, the major capabilities developed within this framework have generally been initiated and majority-funded by the United States. The fact that Canada takes the lead on A-OTHR — with Australian technology, an Australian contractor, and confirmed Canadian funding of $2.5 billion — represents a qualitative change in Canada's contribution to North American defence. This is the concrete materialization of the rhetoric on Canadian rearmament: no longer budgetary promises, but signed contracts and construction sites starting July 1, 2026.

The Australian dimension: the country's largest ever defence export

Canberra as an Indo-Pacific and Arctic security partner

For Australia, the agreement of June 22, 2026 represents a historic moment. According to ABC News Australia reports, this is the most lucrative defence export in Australian history — and the first time Australia has exported its OTHR technology. It is a significant transformation of Australia's industrial positioning in the international defence space. The government of Prime Minister Anthony Albanese made the expansion of defence exports a priority within Australia's strategy to strengthen its defence industrial base — the Australian Defence Strategic Review of 2023 had explicitly identified OTHR technology as a domain of national excellence capable of generating leading exports. The Canadian contract validates that strategy at the highest level.

Five Eyes, Ghost Bat and the strategic depth of the bilateral partnership

The Canada-Australia relationship in the defence domain has deepened considerably since 2021. Both countries are part of the Five Eyes (FVEY) — the intelligence sharing network between Canada, the United States, the United Kingdom, Australia and New Zealand. They share a common geopolitical vision on the threats posed by authoritarian China in the Indo-Pacific and a growing concern about the militarization of the Arctic by Russia. Discussions reported by True North Strategic Review in June 2026 also evoke Canadian interest in the Ghost Bat — the Australian unmanned combat drone developed by Boeing Australia, with a range of approximately 3,700 kilometres — as a potential future element of a multi-domain Arctic defence network. The A-OTHR agreement is therefore more than a radar contract. It is the foundation of a strategic bilateral defence partnership whose ramifications extend well beyond the program itself.

The strategic context: why the Arctic is suddenly the priority

Russian militarization, melting ice and new routes — a convergence of risks

The urgency of the A-OTHR program can only be understood by measuring the rapid transformation of the Arctic strategic context since 2014. Russia has massively reinforced its military presence in the Arctic since the Crimea annexation: reopening and modernization of abandoned Soviet military bases (Tiksi, Franz Josef Land, Novaya Zemlya), deployment of S-400 and S-300 surface-to-air missile systems in the region, development of nuclear-powered submarines of the Borei class specifically designed to operate under the Arctic ice cap, and integration of the Northern Sea Route into Russia's logistical and economic strategy. These military developments are accompanied by the accelerated melting of sea ice — which makes the Northwest Passage and Northern Sea Route accessible for increasingly long periods each year — opening new commercial routes but also new military approach lines previously impractical.

From General O'Shaughnessy's testimony to the Canberra agreement — six years of strategic pressure

In this context, the gaps in the North Warning System — a radar and sensor infrastructure built primarily in the 1980s and obsolescent relative to current threats — constitute a vulnerability that the United States was the first to formally identify. In 2019, General Terrence O'Shaughnessy, then NORAD commander, testified before the US Senate that Russian investments in long-range weapons systems had created deep-strike capabilities in North America that NORAD could not detect with its current systems. This public testimony from an American general on North American continental defence gaps was the political trigger that put the A-OTHR file on the priority agenda of both capitals. Prime Minister Carney announced an investment of more than $6 billion in the A-OTHR program as early as March 18, 2025. The agreement of June 22, 2026 makes that announcement concrete.

Canadian industrial spinoffs: 2,270 jobs and $290 million per year

A defence program as a national economic investment

The Canadian government published precise estimates of the A-OTHR program's economic spinoffs: a contribution of approximately $290 million per year to Canadian GDP and support for approximately 2,270 annual jobs in the Canadian economy during the period from 2026 to 2033. These figures come from the economic impact estimates included in the official program documents published on June 22, 2026. They cover only the initial development and construction period — the system's operational and maintenance phases, extending over decades, will generate additional economic spinoffs not yet officially calculated. The industrial and technological benefits (ITB) agreement signed with BAE Systems Australia guarantees that Canadian companies will participate in the construction and maintenance of the system — a contractual condition that directs part of the work toward Canadian firms specializing in electronic engineering, radio frequencies and military infrastructure construction.

Aecon, Pomerleau, Stantec — the national consortium serving the program

Canadian companies already engaged in the program include the Aecon-Pomerleau-Stantec consortium for Phase 1 infrastructure construction. Aecon, a Toronto-based infrastructure construction company, and Pomerleau, a Quebec construction firm, form a 50/50 partnership for project delivery — ensuring both an Ontario and Quebec presence in the program. Stantec, a multidisciplinary Canadian engineering firm present across the country, provides engineering and design services. These three firms already represent thousands of skilled jobs in their respective domains. The A-OTHR contract adds to their order books at a time when the Canadian defence infrastructure construction sector is experiencing an unprecedented expansion — financed by the rearmament commitments announced since 2022.

The ambitious timeline: December 2029 as the initial capability horizon

A program that cannot afford delays

The date of December 2029 for the A-OTHR program's initial operating capability is both ambitious and necessary. BAE Systems Australia begins construction on July 1, 2026. For a program of this complexity — including radar component design and manufacturing, Ontario site construction, system installation and integration, testing and operational qualification — achieving initial capability in three and a half years is a tight schedule. Analysts from True North Strategic Review note that the target date fluctuates between 2029/2030 for minimum viable capability, and that full operating capability (FOC) is estimated in the 2035/2036 to 2042/2043 window depending on phases. This wide range reflects the normal uncertainty associated with a technology development program of this scale — and the fact that later phases are still under planning.

Programmatic risk factors in the Canadian context

The risk of schedule slippage is real and worth naming. Canada has a long history of defence programs taking two to three times longer than planned — from the Halifax-class frigates to the CF-18, through the offshore patrol vessels and persistent problems with the Victoria-class submarine program. For the A-OTHR program, several structural factors could create slippage: the complexity of integrating an OTHR system in Arctic conditions different from the Australian JORN, local opposition to the sites — True North Strategic Review noted in March 2026 that both Ontario sites faced significant local opposition — and the contractual management of a government-to-government relationship involving decision-making processes in two countries. The Carney government has displayed a strong political will to maintain the schedule. Political will does not always suffice. But it is the necessary condition.

The NORAD dimension: Canada reclaims its place in continental defence

A leadership role in a historic binational command

NORAD — the North American Aerospace Defense Command — is the binational command created in 1957 to ensure the aerospace defence of the North American continent. For almost seven decades, this command has functioned with a real but asymmetric Canadian contribution: the United States has provided the vast majority of surveillance systems, interceptors and technological infrastructure, while Canada has provided bases, airspace and personnel contributions. This asymmetry has created, over the decades, a Canadian dependence on American investments in continental defence — a politically uncomfortable situation that successive governments have tried to correct without ever really succeeding. The A-OTHR program, identified by NORAD itself as the first major capability led by Canada within this command, represents a break with this pattern.

The message sent to Washington — and to Moscow

For the United States, the fact that Canada invests $2.5 billion in a capability that directly benefits NORAD — and thus American defence — is welcomed in Washington defence circles. The Pentagon and the US Congress have on multiple occasions expressed frustrations about Canadian defence investment levels. The A-OTHR program, combined with spending commitments toward 5% of GDP by 2035, negotiations on the M-346, the 162 sanctions against the Russian shadow fleet — taken together, these signals constitute a coherent message: Canada is serious about its contribution to collective security. That message has value in the bilateral relationship with the United States, regardless of which administration is in place in Washington.

Implementation challenges: local opposition, technical complexity and binational governance

Three real obstacles to on-time delivery

Local opposition to the A-OTHR program sites in Ontario is a concrete challenge that official documents minimize. Landowners and residents in the areas surrounding Kawartha Lakes and Clearview Township have expressed concerns about impact on agriculture, the landscape, electromagnetic emissions and land values. True North Strategic Review noted in March 2026 that both sites were still facing major local opposition. The federal government has engaged a public consultation process, including virtual and in-person information sessions, but resolving these local tensions represents a real delay risk. By comparison, Australian JORN sites are located in very sparsely populated areas — the geographic constraint of having to install the first sites in Ontario, where electrical infrastructure is available, creates precisely the type of friction with local communities that planners had to anticipate but that government communiqués tend to understate.

Binational governance — approval processes in two capitals

On the program governance front, managing a government-to-government contract between Canada and Australia with BAE Systems Australia as the prime contractor creates additional complexities. Major technical decisions will involve approval cycles in two different governments. Contract modifications — inevitable in any development program of this complexity — will need to follow acquisition processes compatible between the Canadian and Australian systems. The geographic distance between Ottawa and Canberra — approximately 15,000 kilometres — adds real logistical constraints for technical exchanges. These challenges are manageable. They are not manageable without rigorous program governance, human resources dedicated full-time to bilateral coordination, and sustained political will on both sides of the Pacific.

Canadian industrial partners: the ecosystem building around the program

Aecon, Pomerleau, Stantec — a national consortium for critical infrastructure

The A-OTHR program relies on a network of Canadian companies that goes well beyond BAE Systems Australia as the prime contractor. In March 2026, an integrated project delivery agreement was finalized between Defence Construction Canada and a consortium comprising Aecon (infrastructure construction), Pomerleau (civil engineering and building) and Stantec (multidisciplinary engineering). This consortium forms the backbone of Phase 1 infrastructure construction — the Kawartha Lakes and Clearview Township sites. Aecon and Pomerleau form a 50/50 partnership for project delivery, with Stantec providing engineering and design services. This equitable partnership structure between a Toronto firm and a Quebec firm reflects a geographically distributed approach to spinoffs that is politically significant in the Canadian context. The two most populous provinces directly benefit from contracts linked to this national defence program.

The ITB agreement as a mechanism for guaranteed industrial spinoffs

Beyond the construction consortium, the A-OTHR program should generate spinoffs in other sectors of Canadian industry: power supply and energy distribution systems (radar installations of this scale consume considerable quantities of electricity), companies specializing in signal processing and data fusion software, suppliers of cooling systems for high-thermal-density electronic equipment, and specialists in difficult-environment construction who will intervene on the later, more northerly phases of the program. The industrial and technological benefits agreement signed with BAE Systems Australia on June 22, 2026 is the contractual mechanism guaranteeing these spinoffs do not remain promises — they are obligations binding the Australian company to measurable commitments in the Canadian economy.

The A-OTHR program and Arctic sovereignty: beyond military defence

Maritime surveillance, border control and northern diplomacy

The value of the A-OTHR program exceeds its strict military application. A long-range radar surveillance system covering Canada's northern approaches offers capabilities useful in non-military domains: maritime surveillance (detection of undeclared vessels transiting Canadian Arctic waters), border control (monitoring air movement in areas where conventional radar coverage is lacking), and search and rescue (detection and tracking of aircraft or vessels in distress in the Arctic). These dual-use capabilities — military and civilian — increase the investment's overall value and facilitate its political acceptability. A program presented solely as a war tool against Russian threats encounters different resistance from one presented as a multipurpose sovereignty and security system.

The Northwest Passage dispute — seeing in order to affirm

Canadian sovereignty in the Arctic is a complex political question that goes well beyond military defence. Canada claims control over the Northwest Passage that the United States and other countries consider international waters — an unresolved legal divergence that is taking on increasing practical dimensions as climate warming makes this passage navigable. The ability to monitor and document vessel movement in these waters through a system like A-OTHR strengthens Canada's position in this dispute — not through coercion, but through presence and knowledge. Knowing what is happening in your own waters is the prerequisite for any credible claim of sovereignty over those waters. The A-OTHR program gives Canada the eyes it needs to exercise that sovereignty with conviction.

The Australian Ghost Bat and the technological horizon of the Canada-Australia partnership

Beyond the radar, a defence relationship building over time

The agreement of June 22, 2026 on the A-OTHR program is not isolated in the Canada-Australia defence relationship. Information published by True North Strategic Review in June 2026 indicates that Canada has expressed interest in the Australian unmanned combat drone Ghost Bat — a system developed by Boeing Australia, with an operational range of approximately 3,700 kilometres and a design specifically optimized for escort operations accompanying piloted fighters like the F-35. The Ghost Bat is not yet in serial production, and no formal Canadian acquisition decision has been announced. But the documented Canadian interest in this platform fits within the logic of the A-OTHR partnership: both countries are developing a defence cooperation relationship that goes beyond a one-off transaction to become a structural technological collaboration.

A deliberately multilateral procurement policy

A Canada acquiring Australian over-the-horizon radars and exploring the acquisition of Australian combat drones is a Canada whose defence procurement policy is becoming deliberately multilateral — reducing its exclusive dependence on American and British equipment, while remaining within the allied technological ecosystem. This supplier diversification has strategic advantages: it reduces supply disruption risks linked to dependence on a single supplier, it develops Canadian industrial competencies in new technological domains, and it strengthens allied network depth by multiplying bilateral defence cooperation relationships. The A-OTHR agreement is therefore, in historical perspective, perhaps as important for what it initiates as for what it delivers — a strategic relationship with Australia that could define a significant dimension of Canadian defence policy for the decades to come.

Conclusion: The Canberra agreement and the refounding of Canadian Arctic sovereignty

An investment that will define Canadian national security for fifty years

The signature of June 22, 2026 in Canberra is a founding act. Not in the rhetorical sense of the term — in the literal sense: it founds something that did not exist. Canada will have, for the first time in its history, a radar surveillance system capable of seeing its northern approaches at distances no previous instrument could reach. A system capable of detecting low-flying cruise missiles, stealthy aircraft, hypersonic vectors emerging from the Arctic or circumventing the continent from the north. A system that fills the most fundamental gap in North American continental defence since the end of the Cold War. This is not an exaggeration. It is the documented reality of the capabilities that the agreement of June 22 sets in motion. And BAE Systems Australia begins construction on July 1, 2026 — nine days after the signature at the time of writing. This schedule says something important about the seriousness of the commitment.

The conditions of a success that is not yet secured

Legitimate uncertainties remain. The December 2029 schedule for initial capability is ambitious. Local opposition in Ontario must be managed. Binational governance requires resources and sustained political will over time. And beyond Phase 1, the later phases of the program that will provide complete Arctic coverage remain to be planned in detail. These uncertainties are real and honest. But they do not diminish the historical importance of the moment. Canada is investing $2.5 billion confirmed — in a program estimated at more than $6 billion in its final configuration — to purchase a capability that will structurally change its national security posture. It is choosing an Australian partner whose expertise is uncontested. It is creating jobs, economic spinoffs, national industrial expertise. And it is sending a clear message to Moscow: the Canadian Arctic will no longer be a blind approach zone. That message requires no translation.
