A Distributional Analysis of a National Guaranteed Basic Income (Office of the Parliamentary Budget Officer, 2025 Update)

Summary

Canada's independent Office of the Parliamentary Budget Officer (PBO) has costed a national guaranteed basic income (GBI) four times since 2018, each time using Ontario's cancelled 2017 basic income pilot's design (a negative-income-tax-style, income-tested benefit, not a universal payment): a guarantee equal to 75% of Statistics Canada's Low-Income Measure, clawed back at $0.50 per dollar of earnings, plus a disability supplement. This entry centers on the most recent installment, A Distributional Analysis of a National Guaranteed Basic Income – Update (RP-2425-029-S, 19 February 2025), fetched directly from PBO's website, with three earlier reports read as lineage: the 2018 national costing (RP-1819-370), the July 2020 COVID-era costing (RP-2021-014-M), and the April 2021 full distributional/fiscal analysis (RP-2122-001-S).

The Core Argument / Findings

The 2025 Update responds to renewed parliamentary interest (House Bill C-223 and Senate Bill S-233, proposing a national "guaranteed livable basic income" framework) and, new relative to 2021, models the GBI under two family-unit definitions — the narrower "nuclear family" (adult children living with parents qualify separately) and the broader "economic family" (pools related household members' income):

• Gross cost. Static gross cost (benefit outlay before behavioural effects) is $107 billion in 2025 under the nuclear-family definition, or $53 billion — "roughly cut in half" — under the economic-family definition, since pooling household income disqualifies more people.
• Fiscal offsets. PBO assumes existing low-income tax credits are eliminated and basic personal amounts reduced to fund the gross cost — raising an estimated $56B federal + $50B provincial (nuclear family) or $28B + $25B (economic family), which "fully fund" the gross static cost.
• Distributional impact. In both scenarios the net effect on disposable income is progressive: the largest gains go to the lowest quintile, while higher quintiles lose as tax credits are removed and their GBI transfer is small or zero.
• Poverty reduction. On the Market Basket Measure (MBM), the GBI "would reduce poverty rates in Canada in 2025 by 34 per cent under the nuclear family definition and by 40 per cent under the economic family definition" — a relative reduction, not a 40-percentage-point cut. This is lower than the ~49% PBO reported in 2021, attributed mainly to a revised, higher MBM threshold (rebased 2008→2018), not to any design change.
• The net-cost claim, verified. "The cost of the behavioural response to the GBI under the nuclear family definition would amount to $5 billion, compared to $3.6 billion under the economic family definition ... leaving the behavioural cost of the GBI as the only net cost for the government." The $3.6B net-cost figure and the 40% poverty-reduction figure are the same scenario (economic family) — commonly cited together, and internally consistent, not a mismatch. The behavioural cost reflects hours worked down 1.1-1.4% and payroll down 0.4-0.5%, using labour-supply elasticities from Green (2020) — the same David Green who chaired the BC Basic Income Panel and whose separate work critiques the Mincome hospitalization finding (see Forget and BC panel entries).

Lineage. The 2018 report (for MP Pierre Poilievre) found the Ontario-pilot design would cost $76.0B nationally in 2018-19, rising to $79.5B by 2022-23, for 7.5M+ beneficiaries — costing only, no poverty analysis. The July 2020 COVID-era report estimated a 6-month gross cost of $45.8-96.4B across three clawback scenarios, explicitly excluding behavioural effects. The April 2021 report first added distributional/behavioural analysis: gross cost $85B (2021-22) to $93B (2025-26); lowest quintile +$4,535 (+17.5%); poverty down "almost half" on the MBM; behavioural net cost $3.0-3.3B/year — the direct ancestor of the 2025 Update.

Relation to the Georgist Case

Like the other two entries in this trio, the PBO's GBI is financed entirely from the existing general tax base — not land or resource rent. It bears on the Georgist case through the same citizen's-dividend lane: evidence about what an unconditional-ish cash transfer does, independent of funding. Two features matter for Georgists specifically. First, the PBO's GBI is income-tested, not universal — its low net cost comes substantially from the same targeting-efficiency logic the BC Basic Income Panel uses against a true UBI; a genuinely universal, unconditional rent-funded dividend would not benefit from this clawback-driven cost containment and would cost closer to the PBO's gross figures ($53-107B) than its net figures ($3.6-5B). Second, the "fully offset" framing means the $3.6-5B "net cost" is not free money — it is the residual after a large implicit reallocation (tens of billions in tax credits eliminated, borne disproportionately by middle earners), a trade-off a rent-funded dividend, drawing on revenue not currently collected at all, would not need to make the same way.

Nuances and Limits

• "Net cost" is a narrow, government-accounting concept, not a claim the program is nearly free. The gross program is $53-107 billion; only the $3.6-5 billion sliver left after PBO's assumed full offsetting elimination of low-income tax credits counts as "net." The offsetting elimination is itself a major, contestable policy choice that shifts costs onto other households rather than eliminating them.
• Poverty reduction is model- and threshold-sensitive. The drop from ~49% (2021) to 34-40% (2025) is attributed by PBO to a revised MBM threshold, not a change in GBI generosity — a caution against treating any single-year percentage as stable.
• Uncertain behavioural-cost lower bound. PBO notes Boadway et al. (2023), costing a provincial GBI for PEI, use higher labour-supply elasticities, implying "the behavioural cost of a national GBI shown in this report may represent a lower bound estimate."
• SPSD/M data limitations. PBO states the microsimulation data "likely does not capture the full scope of poverty in Canada," meaning both cost and poverty-reduction estimates could be understated.
• Financing is only one design. "There remains considerable uncertainty surrounding how a national GBI would ultimately be structured and financed," per the report's own limitations section.
• The task brief's "2020 costing" URL was dead. pbo-dpb.gc.ca/.../RP-2021-010-M_en.pdf 301-redirects to a JavaScript shell page on PBO's migrated site and does not serve a PDF; this entry cites the three verifiable earlier reports (2018, July 2020, April 2021) located directly on the current PBO site instead.

Bears On

• Benefit (supports, general basic-income evidence, not rent-specific): Rent dividends reduce poverty and inequality — an official costing showing a national cash-transfer program cuts measured poverty by roughly a third to two-fifths, reinforcing the underlying mechanism a rent-funded dividend would also rely on, using general tax revenue rather than rent.
• Relates to (methodological corroboration): Covering All the Basics: the BC Basic Income Panel's Final Report — the PBO's low "net" cost illustrates, from a different government body, the same targeting-efficiency dynamic (income-tested transfers cost far less than universal ones) the BC panel uses against a true UBI.
• Objection (bears both ways): Universal transfers are an inefficient way to reduce poverty — the income-tested design behind PBO's low net cost illustrates the objection's targeting logic, while the same report's gross-vs-net accounting supplies the proponents' framing response quoted there.
