General Gov. Net Debt (% GDP)

Canada vs US net debt-to-GDP: why the gap is so extreme (and partly an accounting artifact)

On the raw OECD series, Canadian net debt-to-GDP is around 8% and US net debt-to-GDP is around 102%. A gap of nearly 100 percentage points is almost hard to believe between two otherwise-similar advanced economies, and in fact most of it reflects a very specific accounting choice that is worth understanding before drawing conclusions. This page explains the gap, what it does and does not mean, and where the two fiscal trajectories are heading.

For the definition of net debt (gross debt minus government financial assets) and the difference between federal-only and general-government measures, see the Net Debt to GDP indicator page. This page is about the Canada–US gap.

The headline numbers

From the OECD general-government figures shown above:

• United States, 2000: roughly 35% of GDP net debt.
• United States, 2026 (projected): roughly 102% of GDP.
• Canada, 2000: roughly 46% of GDP net debt.
• Canada, 2026 (projected): roughly 8% of GDP.

That is a 67-percentage-point deterioration in the United States and a 38-percentage-point improvement in Canada over the same quarter century — a 105-point swing. The two countries have fiscally traded places in a way that is genuinely rare in advanced-economy history. But the gap is smaller than it looks once you unpack the denominator, and the trajectory matters more than the level.

The CPP asymmetry is doing a lot of the work

The single biggest reason the Canadian number is so low is that the Canada Pension Plan and Quebec Pension Plan hold very large financial assets that are netted against government liabilities under OECD methodology. The CPP Investment Board alone held roughly CAD $777.5 billion in assets at the end of Q2 fiscal year 2026, with another roughly $100 billion at the QPP (Caisse de dépôt).

The US Social Security Trust Funds hold their reserves in non-marketable Treasury securities, which are internal government debt and therefore do not reduce the net debt figure in the same way. The funds are projected to exhaust their reserves in the early-to-mid 2030s on current policy.

Statistics Canada publishes two parallel series that make this explicit. For Q2 2025:

• Canadian general-government net debt including CPP/QPP assets: about 17.8% of GDP.
• Canadian general-government net debt excluding pension plan assets: about 46.1% of GDP.

The difference — roughly 28 percentage points — is the CPP/QPP adjustment. If you netted US Social Security reserves the same way Canada nets CPP, the headline US net debt figure would fall by several percentage points but not dramatically, because the Social Security reserves are not remotely the same size relative to GDP.

In other words: a large share of the Canada–US net debt gap is a real story about Canada actually pre-funding its public pensions, and a smaller share is a pure accounting-convention effect. Both framings matter.

The US trajectory: unambiguously deteriorating

Even if you set aside the CPP adjustment, the direction of travel is stark. The Congressional Budget Office's January 2026 long-term outlook projects:

• US federal debt held by the public at roughly 101% of GDP in 2026, rising to approximately 120% by 2036.
• That level passes the previous post-war peak set in 1946 at the end of World War II.
• US net interest payments in FY2024 reached approximately $881 billion, which is now larger than the defence budget and larger than Medicare outlays.

The 2025 "One Big Beautiful Bill Act" (OBBBA), signed in July 2025, added roughly $4.1–4.7 trillion to projected debt over a decade according to CBO scoring — a significant upward revision to the trajectory. Analysts including Maya MacGuineas at the Committee for a Responsible Federal Budget have described the US fiscal position as "crisis worsening" territory, and Bridgewater founder Ray Dalio has used the more dramatic "debt heart attack" framing in recent commentary.

The IMF's Article IV consultation for the US projects federal debt in the 128–130% of GDP range by 2030 if current policy continues, which would place the United States in the upper tier of highly-indebted advanced economies.

The Canadian trajectory: deteriorating too, but from a much stronger base

The Canadian federal number is also drifting higher, just from a much better starting position. Budget 2025 (delivered in late 2024) projected an average federal deficit of roughly CAD $64.3 billion per year over the medium term, and the C.D. Howe Institute's 2025 Shadow Budget described the federal fiscal track as meaningfully looser than previous plans.

Provincial debt is the bigger drag most consumers don't see. Ontario alone has accumulated roughly CAD $421 billion in provincial debt despite only reporting around CAD $224 billion in cumulative deficits — the difference is off-book capital spending and asset impairments that still land on the balance sheet. Quebec and Alberta have their own trajectories worth tracking separately.

The Parliamentary Budget Officer, currently Yves Giroux, has described the federal trajectory as "challenging but sustainable" in the most recent Fiscal Sustainability Report. Former PBO Kevin Page has been more blunt, arguing publicly that the pace of new spending is incompatible with long-run sustainability without revenue measures. Both views are defensible depending on which time horizon and which discount rate you use.

The historical anchor worth remembering is Finance Minister Paul Martin's 1995 federal budget, often called the "Hell or High Water" budget, which cut federal program spending significantly and set Canada on a two-decade path of falling debt ratios. The current Canadian net debt position is the legacy of that budget compounding over thirty years. The US had no equivalent inflection.

What the gap does and does not mean

It does mean:

• Canada has more fiscal room to respond to a recession or a tariff shock without triggering a debt crisis or a sovereign rating downgrade.
• The US is in a materially worse position to absorb further fiscal surprises, and interest costs are eating an increasing share of the federal budget.
• Canada's pre-funded public pensions are a real structural advantage, not just a statistical quirk.

It does not mean:

• That Canadian government finances are healthy in an absolute sense — the federal trajectory is drifting the wrong way and provincial debt is high by historical standards.
• That the US is about to default — the United States retains the world's reserve currency, the deepest sovereign bond market, and structural demand for Treasuries from both domestic and foreign investors.
• That the CPP/QPP assets are "free money." They back a real liability (future pension benefits) that is growing with demographics.

What to watch in 2026

1. CBO updates to the US trajectory after any fiscal-year 2026 supplemental spending or additional tax policy moves. Any upward revision past the 120%-by-2036 baseline is meaningful.
2. Provincial budgets in Canada, especially Ontario, BC, and Quebec. The federal number is only half the story.
3. The Canada–US 10-year yield spread, which is the market's real-time opinion on the relative fiscal sustainability of the two countries.
4. Any change to CPP contribution rates or benefits, which would change the asset trajectory and, mechanically, the net-debt ratio.

The short version: the 100-point gap between Canada and the United States on net debt-to-GDP is real, it is partly an accounting story about pre-funded pensions, and it is directional in a way that matters for policy. Canada's lead is not permanent, and the US position is deteriorating faster than most people realize. Reading the two lines together — not the Canadian or the US line alone — is the only honest way to assess either country's fiscal capacity.
