NATO's 5 Per Cent Target Would Cost Canada $150 Billion a Year, Carney Says

Meeting NATO's ambitious new defence spending target could cost the federal treasury up to $150 billion a year, Prime Minister Mark Carney has warned, laying bare the enormous fiscal challenge confronting Canada as the Western alliance ramps up its expectations of members. The figure underscores the scale of the commitment Canada has signed on to and the difficult choices ahead as the government balances a sweeping defence buildup against competing domestic priorities and a weak economy.

The new benchmark

At the alliance's summit in The Hague, NATO members committed to investing 5 per cent of gross domestic product annually on defence and security-related spending by 2035. The target is broken into two components: at least 3.5 per cent of GDP devoted to core defence requirements, and a further 1.5 per cent for related investments in areas such as infrastructure and security.

The new benchmark represents a dramatic escalation from the long-standing 2 per cent target that many members, including Canada, had struggled for years to meet. The push reflects a transformed security environment, shaped by the war in Ukraine and broader concerns about the alliance's readiness, that has prompted members to dramatically raise their ambitions.

For Canada, the implications are profound. Carney has said that signing on to the target could cost the federal treasury up to $150 billion a year, with the government needing to find an additional $45 billion to $50 billion to meet the 3.5 per cent direct military spending portion alone. Those are staggering sums for a federal budget already under pressure.

Canada's progress so far

Canada has made notable progress on the previous benchmark. The government announced earlier in the year that the country had achieved the 2 per cent defence spending target, reaching that level of military spending for the first time in decades. Officials have described that milestone as a foundational step in a broader effort to renew Canada's defence capabilities.

That achievement, however, only sets the stage for the far steeper climb to come. Moving from 2 per cent to 3.5 per cent of GDP in direct military spending, let alone the full 5 per cent target including related investments, would require sustained increases of a magnitude that will reshape federal budgeting for years.

The government has paired its spending commitments with structural moves to build up the defence sector. It has launched initiatives aimed at transforming defence procurement, prioritising Canadian suppliers and materials, and scaling up the domestic defence industrial base, alongside a major new defence partnership announced in recent days.

The fiscal challenge

The central difficulty is fiscal. Finding tens of billions of dollars in additional annual defence spending would be challenging in any circumstances, but it is especially daunting against the current economic backdrop. The economy has stalled, with output flat in the first quarter and the country having posted back-to-back quarterly declines, limiting the revenue growth that might otherwise help fund the buildup.

The defence commitment also competes with a long list of other priorities. The government is pursuing an ambitious investment agenda, faces pressure to sustain social programs such as pharmacare, and must manage the broader strains on federal finances. Every dollar directed to defence is a dollar not available for other purposes, sharpening the tradeoffs the government must navigate.

Those tradeoffs will force difficult political choices. Sustained increases in defence spending of the scale required could necessitate spending restraint elsewhere, higher revenues or larger deficits, each of which carries its own political and economic costs. How the government threads that needle will be one of the defining fiscal questions of its mandate.

The strategic rationale

Behind the daunting numbers lies a strategic rationale that the government and the alliance argue is compelling. The security environment has deteriorated markedly, with the war in Ukraine demonstrating the consequences of military weakness and underscoring the need for credible deterrence. NATO members have concluded that the alliance must invest far more to remain capable.

For Canada, the buildup also responds to long-standing criticism, including from the United States, that the country has not pulled its weight on defence. Meeting the new targets would address that criticism and strengthen Canada's standing within the alliance, a consideration with added weight given the strained state of the relationship with Washington.

The government has framed its defence investments as essential to renewing capabilities that have been allowed to atrophy, from military procurement to industrial capacity. In that view, the spending is not merely an obligation to allies but a necessary investment in Canada's own security and sovereignty in a more dangerous world.

What it means for Canadians

For Canadians, the defence buildup represents one of the most significant shifts in federal priorities in a generation. Spending of the magnitude contemplated would have implications for the broader budget, potentially affecting the resources available for other programs and the government's fiscal position.

The buildup also carries economic opportunities. The government's emphasis on prioritising Canadian suppliers and scaling up the domestic defence industrial base could generate jobs, investment and industrial capacity, particularly if the spending is channelled into domestic production. Defence has been identified as one of the sectors central to the government's broader investment ambitions.

At the same time, the scale of the commitment raises questions about sustainability and tradeoffs that will affect Canadians directly. Whether the spending is funded through restraint elsewhere, higher revenues or deficits will shape its impact on households and the broader economy.

Years of underinvestment

Canada's challenge in meeting the new targets is compounded by decades of relative underinvestment in defence. For years, the country fell short of the alliance's 2 per cent benchmark, drawing periodic criticism from allies, particularly the United States, who argued that Canada was not contributing its fair share to collective security. The recent achievement of the 2 per cent target marked a notable reversal of that long pattern.

That history of underinvestment has left the Canadian military with capability gaps and equipment in need of modernisation, from naval vessels to aircraft and beyond. Rebuilding those capabilities is part of what the increased spending is meant to address, and the government has framed its investments as a renewal of forces that were allowed to deteriorate over years of fiscal restraint.

The legacy of underinvestment also means that ramping up spending is not simply a matter of writing larger cheques. Building capacity takes time, from procurement processes to the development of a domestic defence industrial base capable of delivering. The government's emphasis on reforming procurement and scaling up Canadian industry reflects a recognition that money alone, without the capacity to spend it effectively, will not deliver the desired capabilities.

The industrial opportunity

Amid the fiscal challenge lies a potential economic upside. The government has signalled its intention to direct defence spending toward Canadian suppliers and to build up the domestic defence industrial base, an approach that could generate jobs, investment and industrial capacity within Canada rather than channelling the spending abroad.

Defence has been identified as one of the sectors central to the government's broader investment agenda, alongside energy, transportation and data infrastructure. A sustained increase in defence spending, if directed domestically, could provide a significant boost to Canadian manufacturing and technology firms, creating an industrial ecosystem around military procurement.

Realising that opportunity, however, depends on the government's ability to reform a procurement system long criticised for delays, cost overruns and complexity. The initiatives the government has launched to streamline procurement and prioritise Canadian content are aimed at capturing the industrial benefits of the defence buildup. Whether those reforms succeed will help determine whether the enormous spending required becomes a drain on the treasury or an engine of domestic economic activity.

Allied expectations and the American factor

The pressure on Canada to meet the new targets comes not only from within the alliance but from the particular dynamics of its relationship with the United States. Washington has long pressed allies, Canada included, to increase defence spending, and the criticism has at times been pointed. Meeting the targets would address that long-standing source of friction.

That consideration carries added weight given the strained state of the broader Canada-United States relationship, with the trade conflict casting a shadow over cross-border ties. Demonstrating a credible commitment to defence spending could help Canada shore up its standing with Washington on the security file even as economic disputes persist, offering a point of cooperation amid the tension.

At the same time, the alliance as a whole is watching how members translate the ambitious targets into action. The credibility of the collective commitment depends on members following through, and Canada's progress will be measured against that of its peers. Balancing allied expectations against domestic fiscal realities will require the government to chart a course that satisfies partners abroad without imposing unsustainable strain at home.

What's next

The path to the 2035 targets will unfold over a decade, but the choices begin now. The government will face ongoing pressure to demonstrate a credible plan for ramping up spending while managing the fiscal and political constraints that accompany it. Each budget will be scrutinised for progress toward the alliance's expectations.

How Canada balances its defence commitments against its economic challenges and competing priorities will be a recurring theme of the years ahead. The $150 billion figure Carney has cited captures the magnitude of the undertaking and the difficult arithmetic involved. For a country navigating a weak economy, a tense relationship with its closest ally and a transformed security landscape, meeting NATO's ambitions will demand sustained commitment and hard choices.

The coming years will reveal whether Canada can reconcile the competing demands it faces: honouring its commitments to allies, rebuilding capabilities eroded by years of underinvestment, capturing the industrial benefits of the buildup and managing the fiscal strain, all while navigating a weak economy and a difficult relationship with its closest partner. The scale of the undertaking is immense, and the choices it forces will shape not only Canada's defence posture but its broader fiscal and economic trajectory. For a country accustomed to relying on others for its security, the era of dramatically higher defence spending represents a profound shift whose full implications are only beginning to come into focus.
