Executive summary

Canada’s Budget 2025 projects public debt charges (interest on the federal debt) of $55.6 billion for fiscal 2025–26, which the government says equals about 1.8% of GDP (Budget 2025 Annex 4) [1]. Other summaries and commentators translate that dollar figure into political comparisons — for example, noting interest payments exceed certain federal transfers — but the core official figure in available sources is $55.6 billion [1] [2].

1. What the government reports: the headline number

The federal Budget 2025 and its Debt Management Strategy explicitly state that public debt charges are projected at $55.6 billion in 2025–26 and quantify that as roughly 1.8% of GDP (Annex 4 of Budget 2025) [1]. Annex 1 of the Budget places the overall 2025–26 deficit at $78.3 billion, or 2.5% of GDP, which provides the spending context for the interest-cost figure [3].

2. How journalists and analysts frame that figure

News outlets and policy groups have highlighted that $55.6 billion is large enough to draw direct comparisons with major program spending. For instance, reporting and commentary note that projected interest payments are comparable to, or exceed, transfers for health care and child care in certain later years — a framing used to signal fiscal trade-offs in Budget 2025 [4] [2]. The National Post and The Hub cite projections of growing interest costs over the decade, including a government projection of $76.1 billion by 2029–30 that underpins such comparisons [5] [4].

3. Percent of the federal budget: what’s missing in the sources

None of the provided sources directly state “what percentage of the federal budget” the 2025 interest payments represent relative to total federal program spending or total federal revenues for 2025–26. The Budget materials give interest in dollars ($55.6 billion) and as a share of GDP (1.8%), and show the overall deficit and debt-to-GDP context, but do not supply a single-line percentage of the federal budget devoted to debt interest in 2025–26 [1] [3]. Available sources do not mention an exact percent-of-budget figure.

4. Two sensible ways to express the answer — and why sources prefer GDP

When journalists ask “what percentage of the budget,” they usually mean (a) interest as a share of total federal expenditures or (b) interest as a share of federal revenues. Budget 2025 chooses a macro framing instead: interest as a share of GDP (1.8%) and absolute dollar amount ($55.6 billion), because GDP-normalized metrics enable cross-year and cross-country comparisons [1] [3]. The Department of Finance and the PBO typically present debt-service in dollars and relative to GDP; the exact “percent of the federal budget” requires combining that $55.6 billion with a specific government total spending or revenue figure not quoted in the excerpts provided [1] [3].

5. What independent commentators add — trajectory and trade-offs

Analysts and think-tanks echo the government’s dollar projections while stressing the upward trajectory: several sources point to interest rising toward $76.1 billion later in the decade and warn that rising debt charges will crowd out program spending unless policy choices change [5] [2] [4]. Some commentary frames the political stakes — for example, contrasting interest costs with healthcare transfers — which is persuasive but depends on which spending lines one chooses to compare [4] [2].

6. Limitations and what to watch next

The publicly cited $55.6 billion figure is a projection in Budget 2025 and therefore sensitive to interest-rate movements, GDP growth, and borrowing needs; the Budget also shows how a 1-percentage-point change in interest rates would materially affect the fiscal balance [3] [1]. For an exact “percentage of the federal budget,” readers should consult the full Budget tables (total program expenses or total revenues) and divide $55.6 billion by the chosen aggregate; the specific percentage is not given in the documents and was not provided in the sources you supplied [1] [3].

7. Bottom line for readers

Cite the government’s official projection: $55.6 billion in public debt charges for 2025–26, about 1.8% of GDP (Budget 2025 Annex 4) [1]. If you need “percent of the federal budget” specifically, the available sources do not state that percentage directly — you can compute it by dividing $55.6 billion by the Budget’s total program spending or revenues in the full Budget tables (not included in the excerpts here) [3] [1].
