Canada and NATO's defence-spending benchmark

A single headline ratio is being used to close a live policy question, but it is built from an estimate on one institution's own definition and forecast-vintage denominator, layered on top of a government's own funding announcement, itself layered on top of departmental plans, voted appropriations, and audited outcomes that each mean something different and arrive on a different clock. Reading the ratio without separating those layers invites exactly the kind of false precision Countability exists to prevent -- and reading them apart, with every formula and assumption disclosed, is what turns a headline into a decision-usable answer.

Scenarios

Directly observed

• Fiscal year 2024-25 (actual, budgetary expenditures used)

Estimated, projected, or otherwise not yet an audited outcome

• Fiscal year 2025-26 (NATO table label: 2025e)
• As referenced throughout NATO's June 2025 Defence Expenditure report
• Fiscal year 2024-25 (NATO table label: 2024e)
• Fiscal year 2023-24 (NATO table label: 2023)
• Fiscal year 2025-26 (government's own announced achievement)
• Fiscal year 2025-26 (NATO 2026-edition table label: 2025e, core defence expenditure only)
• Fiscal year 2026-27 (NATO 2026-edition table label: 2026e, core defence expenditure only)
• NATO's own estimate: fiscal 2024-25 vs fiscal 2025-26
• NATO's own estimate: fiscal 2023-24 (first year this entry captures) vs fiscal 2025-26 (latest)
• Fiscal year 2025-26 (planned, Departmental Plan)
• DND's planned total spending, fiscal 2025-26, vs DND's audited actual spending, fiscal 2024-25
• Core-defence-requirements component of the 2035 guideline, as named in Federal Budget 2025's own reaffirmation of the Hague pledge
• As referenced throughout NATO's 2026 Defence Investment report and Ankara Summit reaffirmation; agreed at the 2025 Hague Summit
• Average annual cost, fiscal years 2026-27 through 2035-36 (PBO projection, published 2026-02-05)
• Fiscal year 2024-25 (PBO projection, published 2024-07-08)

• Fiscal year 2029-30 (PBO projection, stabilized, published 2024-07-08)

Unresolved

• Reach NATO's benchmark of defence expenditure equal to 2% of GDP — no on-pace assessment is published for this target.
• Fiscal year 2025-26: NATO's 2025-edition all-in ratio vs NATO's 2026-edition core-only ratio, same fiscal year
• Countability does not yet hold a continuously updated series for 'Canadian defence expenditure as a share of GDP'. NATO's own published ratio (Defence Expenditure of NATO Countries, most recently June 2025) is a once- or twice-yearly estimate on NATO's own definition (payments to armed forces, eligible 'Other Forces', pensions paid via any ministry, peacekeeping by any ministry, R&D including non-production projects, net NATO common-infrastructure contribution) and NATO's own GDP forecast vintage (IMF/OECD/EC), not a series StatsCan, DND, or any single Canadian institution publishes on a comparable cadence. Canada's own budget, Estimates, and Public Accounts documents report DND-departmental spending on a narrower, differently defined basis (see the NATO defence-expenditure entry).
• Reach NATO's newer guideline of defence investment equal to 5% of GDP annually by 2035 (3.5% core defence requirements plus 1.5% defence- and security-related investment) — no on-pace assessment is published for this target.
• Fiscal 2025-26: NATO's June 2025 estimate vs PBO's July 2024 projection

Key evidence

Method and limitations

• Every value on this Brief resolves to a specific cited value or comparison inside its member Resolution, to its member Target's own cited target value, or to one of this Brief's own scenarios -- each scenario computed here from those same cited inputs plus explicitly stated assumptions, deterministically, before publication, never in the reader's browser. Where evidence disagrees or a figure's definition differs from another figure carrying the same name, both are shown with their own definition rather than merged into one series.
• NATO's own words, from p.1 of the June 2025 report: 'the figures shown in this report may considerably diverge from those that are referenced by media, published by national authorities or given in national budgets.' Every figure in this entry is restated exactly as its own issuer published it; none is adjudicated against another as more correct.
• Numerator/denominator period mismatch: NATO's figures for Canada are stated on a fiscal-year numerator (NATO's own footnote: 'the fiscal year has been designated by the year which includes the highest number of months: e.g. 2023 represents the fiscal year 2023/2024 for Canada') but a calendar-year-forecast denominator (DG ECFIN/IMF/OECD GDP projections as of NATO's 3 June 2025 cut-off) -- two different observation windows fused into one ratio.
• Denominator source and vintage sensitivity: back-solving NATO's own figures (NATO's own published dollar figure and ratio for fiscal 2025-26) implies a GDP denominator of approximately $3,120,050 million for fiscal 2025-26 -- a forecast made as of NATO's 3 June 2025 cut-off, roughly nine months before that fiscal year closes. Statistics Canada's own already-pinned quarterly nominal GDP series (Statistics Canada table 36-10-0104, quarterly nominal GDP) puts the four quarters spanning Canada's actual fiscal year 2025-26 (April 2025 - March 2026: $3,211,260 million, $3,260,736 million, $3,284,580 million, $3,328,492 million) at an average of approximately $3,271,267 million -- about 4.8% higher than NATO's implied denominator. Recomputing NATO's own $62,713 million defence-expenditure figure against this StatsCan-actual average yields approximately 1.92% rather than 2.01%; the same $62,713 million falls roughly $2,712 million short of a 2%-of-GDP threshold measured against this more current denominator. Dated note, 2026-09-02: the last quarter listed here (January to March 2026) read $3,321,588 million, and the four-quarter average $3,269,541 million, until Statistics Canada restated that quarter in the Q2 2026 National Accounts release of 2026-08-28. The shortfall against the 2% threshold read roughly $2,678 million on the earlier figures. The recomputed ratio reads 1.92% on both sets of figures, so what this sensitivity concludes is unchanged; the restatement moved the dollar amounts it is built from, and both are shown. This is a disclosed sensitivity of the ratio to which GDP figure and vintage is used, not a restatement of NATO's own reported number, and not an assertion that NATO's estimate was wrong at the time it was made -- the NATO defence-spending Brief carries the full worked scenario.
• Scope gap between NATO's counted total and DND's own departmental budget: NATO's 2024e figure for Canada is $44,277 million (NATO's own 2024e figure); DND's own audited departmental actual spending for the closest settled fiscal year (2024-25) is $33,924.8 million -- a gap of roughly $10,352 million for approximately the same period. NATO's own defence-expenditure definition includes items DND's own departmental reporting does not carry in the same line: military and civilian pensions paid via other channels, the Communications Security Establishment, eligible portions of other agencies meeting NATO's 'trained and equipped as military, deployable' test, peacekeeping and humanitarian spending by any ministry, research and development including projects that do not lead to production, and Canada's net contribution to NATO common infrastructure. PBO's own scope note similarly names 'the Canadian Armed Forces, the Department of National Defence, and portions of Veterans Affairs Canada' as within NATO's counted scope. This is why no single Canadian appropriation or Public Accounts line reconciles exactly to NATO's reported total -- the gap is definitional, not a data quality problem.
• Estimate, not audited, status: NATO's 2.01% figure for fiscal 2025-26 is an estimate with a 3 June 2025 cut-off, stated before that fiscal year even closes (31 March 2026). The government's own 2026-03-26 announcement of achievement is a political statement citing preliminary spending ('$63 billion... in the past 10 months'), not an audited figure. The only audited figure in this entry (the audited departmental actual) covers fiscal 2024-25, a year in which NATO's own table shows Canada well below 2% (1.47% estimated). The audited settlement of fiscal 2025-26 -- the year the 2% claim actually concerns -- will not exist until the Public Accounts of Canada 2026, expected autumn 2026; when it does, a future capture appends an audited outcome value here rather than editing any value already published.
• Total authorities and lapse, fiscal 2024-25 (Public Accounts, not separately typed as a values[] entry to keep the role vocabulary to genuinely distinct concepts): Department of National Defence total authorities available were $34,711,513,471, of which $30,584,803,954 was the Main Estimates portion (the rest reaching DND through Supplementary Estimates); $772,147,920 of those authorities lapsed (went unspent and unauthorized to carry forward). The $33,924,795,251 'used' figure is what was actually spent, distinct from both the $30,584,803,954 originally voted and the $34,711,513,471 ultimately authorized.
• DND's own Departmental Plan 2025-26 page could not be independently verified byte-for-byte by this reading -- its planned-spending figure is corroborated only indirectly, via the prior year's Departmental Results Report matching the audited Public Accounts figure exactly.
• This entry does not include a Main Estimates 2026-27 figure for National Defence. Secondary reporting (not a primary Countability source) put it at approximately $48.4 billion voted; the primary Treasury Board Main Estimates 2026-27 page could not be fetched by this reading to confirm the figure to the dollar, so it is omitted here rather than stated on unverified authority.
• This entry is filed under the fiscal domain, the closest existing one; it concerns defence expenditure specifically, and no new domain is created to hold it -- the same convention the federal budgetary-balance entry already established. It carries both linked NATO spending commitments -- the 2%-of-GDP benchmark and the newer 5%-by-2035 guideline -- and the published evidence gap on the missing continuously updated indicator, all read by this Brief.
• Maintained-reading refresh, 2026-07-19: this entry's reading changed on new evidence, not a correction of anything previously wrong. Two pieces of evidence already archived as of the 2026-07-12 pass -- the government's own 2%-achieved announcement of 26 March 2026, and Budget 2025 chapter 4's own citation of the Hague 5% pledge -- had not yet been composed into a recorded value on this entry or into the Brief's rendered reading; they are composed now, for the first time. Newly fetched and archived for this reading: NATO's 2026 edition Defence Investment report (cut-off 2026-07-03), its accompanying news update (2026-07-07), NATO's own March 2026 institutional corroboration that all Allies met the 2%-era guideline, the Ankara Summit's reaffirmation of the Hague pathway (2026-07-08), and the Parliamentary Budget Officer's own costing of the 5% commitment (2026-02-05). All publications in this entry from the Government of Canada, NATO, and the Parliamentary Budget Officer were re-reviewed for rights for this reading and moved from an unrecorded licence status to verbatim-permitted: NATO's website terms (Use of NATO content and brand; NATO Archives copyright page) permit non-commercial use of information with attribution, extending 'Fair Use' to the general public for articles -- covering citation of a published statistic with attribution, not redistribution of NATO's materials; PBO's own Terms and Conditions (pbo-dpb.ca) permit non-commercial reproduction without permission, conditioned on no modification, attribution to the Office of the Parliamentary Budget Officer, using the most recent version, and naming title/date/URL -- conditions this platform's citation practice already satisfies; Government of Canada sources are covered by the standing, publicly stated Crown Copyright policy (non-commercial reproduction permitted without permission, subject to no revision/adaptation and attribution of title and author organization), corroborated across multiple .gc.ca policy pages though the specific canada.ca terms page itself declined automated fetch (the same condition already recorded for DND's Departmental Plan 2025-26 page). No source is blocked; none required commercial-use permission for the action taken here.
• Definitional break between NATO's 2025 and 2026 report editions (2026-07-19; figures corrected 2026-07-20 on independent re-reading of the source table): the 2026 edition's Table 3 reports Canada's CORE defence expenditure only (2024=1.41%, 2025e=2.03%, 2026e=2.13% of GDP), not the single all-in ratio the 2025 edition reported against the plain 2% guideline (2024e=1.47%, 2025e=2.01%). The two bases are marked non-comparable for the fiscal year they share; for Canada they in fact track each other closely, so the scope change moves the reported ratio very little. Measured on the like-for-like core-only basis NATO itself now uses, Canada's newest reported ratio (2.13%, fiscal 2026-27) sits 1.37 percentage points below the 3.5% core sub-target of NATO's own 5%-by-2035 guideline -- a plain arithmetic difference stated here rather than as a formal resolution comparison, since a country's reported ratio and an institution's forward benchmark carry different geographies (Canada; NATO) that this ledger's comparison mechanism reserves for same-geography, same-or-related-quantity movements. The gap is of similar shape to, but not the same figure as, the original 2%-guideline gap this entry has always carried.
• Licence verification, corrected 2026-07-20: the NATO and Parliamentary Budget Officer publications on this entry are recorded as verbatim-permitted because those issuers' own terms pages were read and are now archived alongside the citations they license. NATO's terms release articles under 'Fair Use' to the general public and require that republished content be clearly credited to NATO; the OPBO's terms permit use or reproduction for personal and non-commercial purposes without permission, conditioned on no modification, attribution, most-recent-version, and title/date/URL. Countability's use here is citation-with-attribution in free public editorial analysis, within both. The Government of Canada publications on this entry are recorded as unread rather than verbatim-permitted: canada.ca's own terms page could not be fetched by this project (it blocks automated retrieval, consistent with the note on DND's Departmental Plan 2025-26 page), so its terms have not been read from the issuer's own bytes. Crown Copyright's general policy is widely stated to permit non-commercial reproduction with attribution, and nothing here suggests this use is restricted -- but an unread licence is recorded unread rather than inferred.
• The NATO 2026-edition report is over the archive store limit (10.2 MB against a 2 MB threshold), so it is hashed and pinned but not stored in-repo, and it carries no text layer -- its figures must be read visually from rendered page images. Reproducing any figure taken from it requires re-fetching the URL and checking the recorded sha256. That was done on 2026-07-20 and the bytes matched.
• The denominator is an unweighted average of four already-published quarterly observations, fixed in the record -- not a forecast, not seasonally re-adjusted beyond what Statistics Canada itself publishes.
• The numerator is held fixed exactly as NATO reported it; this scenario does not challenge or restate NATO's own numerator, only the denominator applied to it.
• This scenario does not produce an audited or official figure -- it is a disclosed, reproducible recomputation, presented as a sensitivity, not a corrected replacement for NATO's own reported ratio.
• Both figures are expressed against the identical Statistics Canada denominator so the resulting gap reflects scope alone, not a difference in which GDP figure was used.
• Fiscal year 2024-25 is used for both sides because it is the most recent year with an audited DND-departmental actual; NATO's own reported ratio for this same year (1.47%, NATO's own reported ratio) already differs slightly from this scenario's wide-scope recomputation because NATO's own denominator differs from the Statistics Canada denominator used here -- both differences are disclosed together, not merged into one adjustment.
