Federal Spending Methodology
These pages are generated from the Public Accounts of Canada. This page documents the accounting bases, curation choices, and known differences so the numbers are traceable to source.
Volume I vs Volume II basis
Headline totals on the overview page (total spending, revenue, and deficit) use the Volume I consolidated financial statements, which are prepared on an accrual basis and include consolidated Crown corporations. For recent years the overview ministry list and the thematic Sankey are also on this Volume I accrual basis (see the allocation note below), so they sum to the headline exactly. Department pages present net expenditures by standard object from Volume II of the Public Accounts — the same figures the department chart draws (personnel, professional and special services, transfer payments, and so on, net of internal and external revenues). The stat card, the entity list, and the chart on a department page are therefore one consistent number. This net figure differs from the Volume I consolidated headline, so a department’s own total will not match its accrual ministry row on the overview. Parliamentary authorities (votes, allotments, and lapsed amounts) are no longer shown on department pages. The reconciliation below bridges the two bases.
Transfer-payment programs
The Transfer payments standard object on a department chart fans out into its named grant and contribution programs from the Public Accounts. Because the two sources are on slightly different presentations, each program is scaled proportionally so the named programs sum exactly to the chart’s (net) transfer-payments amount; the smaller programs beyond the top ones are grouped into “Other transfer programs”. Program children are shown for the organization that pays essentially all of a portfolio’s transfers; where transfers are split across several organizations, the object is left unsplit. The full, unscaled program list is in the line-item table below the chart.
How ministry and Sankey totals are allocated
On the Volume I accrual basis, each ministry’s total comes from Volume I Table 3.6 (“External expenses by segment and by type”), which reports accrual expenses for each ministerial portfolio. Where our portfolio grouping is finer than the table (for example, a regional development agency reported inside a host portfolio), the segment total is split across the affected portfolios in proportion to their Volume II expenditure shares for that year; where it is coarser, the relevant segments are summed. In the thematic Sankey, each portfolio’s accrual total is spread across its thematic categories in the same proportions as its Volume II lines, and the tax-system and statutory items sourced directly from Volume I (Old Age Security, Employment Insurance, the Canada Child Benefit, major transfers to provinces, public debt charges, and so on) are carved out of the owning portfolio so nothing is double counted. Two non-departmental statement lines — net actuarial losses and the provision for valuation and other items — are shown as their own rows and leaves. Because sub-ministry Sankey leaves are allocated this way, they are proportional estimates, not literal Volume II line amounts; the department page carries the net standard-object detail and its named transfer programs. For older years, each Table 3.6 edition carries the figures as first published while the headline uses the restated ten-year comparative statement, so the vintage segment figures are scaled proportionally to tie to the restated statement totals exactly (and for editions predating the separate net actuarial losses line, that statement amount is carved out of the portfolios the same way). Every year’s ministry list and Sankey therefore sum to the published headline.
Net actuarial losses and the published total
Total spending equals the published Consolidated Statement of Operations total expenses, which include net actuarial losses on pensions and future benefits. In the source statement this line is stored sign-inverted (a loss is shown as a negative number), so we normalize it to a positive cost and place it under Obligations, alongside net interest on debt. With this line included, headline total spending, total revenue, and the deficit match the published statement exactly, and revenue minus spending equals the published Annual operating deficit for every year (a surplus year would show a negative deficit, labelled as a surplus).
Accounting and consolidation adjustments
Every published year is on the Volume I accrual basis, so the spending Sankey sums to the published headline and no adjustments leaf appears. The mechanism remains as a safeguard: should a residual over $1 million ever arise, a single top-level “Accounting and consolidation adjustments” leaf would reconcile the tree to the published total (it may be negative and equals the unattributed remainder in the reconciliation table below), keeping the Sankey and the reconciliation consistent.
Curation differences from the previous site
The previous hand-authored pages contained curated aggregations — for example, hand-massaged negative leaves and thematic groupings that split a single ministry across categories. Every node where the generated tree differs from the previous values is enumerated in the parity report with a reason code (basis, mapping, rounding, or source correction).
Machinery-of-government changes
Ministries have been renamed and merged between 2013 and 2025 (for example, Indian Affairs became Crown-Indigenous Relations). A normalization crosswalk is the canonical mapping; department pages for earlier years render under the current ministry slug with a note stating how the ministry was reported in that fiscal year.
Negative and adjustment rows
Parenthesized negatives, internal consolidation adjustments, and total or subtotal rows are flagged and excluded from Sankey leaves to avoid double counting, but they are retained in the line-item tables so the full detail remains available.
Units
Source tables arrive in mixed units (Volume I in millions, Volume II in dollars, open data CSVs in thousands). All chart data is normalized to billions of dollars; line-item tables are shown in dollars. Each JSON file records its units explicitly.
Thematic mapping
The Sankey uses a curated thematic tree. A maintained mapping assigns each Public Accounts line to a thematic node, mostly at the ministry or organization level with line-level overrides where needed. Each node is truncated to its largest children with the remainder rolled into an “Other” aggregate.
Translation
French labels use official bilingual terminology from open government data as a glossary; only free-text line-item descriptions are machine-translated, with the glossary supplied as required terminology. Translations are committed and reviewed, not generated at build time.
Inflation adjustment
Each year carries a Consumer Price Index multiplier to base-year dollars. The real/nominal toggle scales displayed headline and department figures in the browser; the underlying data is stored in nominal dollars only.
Volume I to Volume II reconciliation, FY 2024-25
| Item | Amount | Note |
|---|---|---|
| Volume I consolidated total | $547.3B | |
| Sum of Volume II ministry totals | $485.35B | |
| Pollution pricing proceeds returned | $15.6B | Vol I consolidated expense line, not present in Vol II appropriations. |
| Employment insurance and support measures | $24.88B | Vol I consolidated expense line, not present in Vol II appropriations. |
| Children's benefits | $28.57B | Vol I consolidated expense line, not present in Vol II appropriations. |
| COVID-19 income support for workers | -$2.17B | Vol I consolidated expense line, not present in Vol II appropriations. |
| Canada emergency wage subsidy | $0 | Vol I consolidated expense line, not present in Vol II appropriations. |
| Net actuarial losses | $4.02B | Vol I consolidated expense line, not present in Vol II appropriations. |
| Consolidation, accrual and gross/net adjustments | -$8.95B | Unattributed remainder: consolidated Crown corporations, accrual items, and gross (Vol II) vs net (Vol I) presentation differences. Every published year is on the Vol I accrual basis, so the spending Sankey ties to the headline and no "Accounting and consolidation adjustments" leaf appears; that leaf remains a dormant safeguard that would surface only if a residual over $1M ever arose. |
| Total difference | $61.95B |
