New Public Sector Accounting Standard: Employee Benefits (PS 3251)

Special Notice – March 15, 2026

In brief:

  • PS 3251 introduces changes to the measurement, presentation, and disclosure of employee benefit obligations for public sector entities, including eliminating deferral and smoothing mechanisms, and requiring immediate recognition of remeasurements.
  • The new standard mandates a funding-status-based approach to discount rates, enhances disclosure requirements, and requires the use of year-end actuarial measurements.
  • Entities will face increased governance, documentation, and disclosure demands, with the potential for higher reported liabilities and greater scrutiny from auditors and stakeholders.
  • It is effective for fiscal years beginning on or after April 1, 2029, with early adoption permitted.

Key implications for public sector pension and benefit plans

The Public Sector Accounting Board (PSAB) has issued a new accounting standard, Section PS 3251, Employee Benefits, which replaces PS 3250 (Retirement Benefits) and PS 3255 (Post-Employment Benefits, Compensated Absences and Termination Benefits).

While PS 3251 does not change benefit promises, plan design, or funding requirements, it introduces significant changes to how employee benefit obligations are measured, presented, and disclosed in public sector financial statements. These changes will affect reported financial positions and may increase volatility in reported results.

Background

PSAB undertook a multiyear review of employee benefits accounting to modernize Canadian public sector standards and improve transparency and comparability. The new standard is based on International Public Sector Accounting Standard (IPSAS) 39, with Canadian-specific adaptations reflecting the governance and funding environment common to public sector pension and benefit plans.

The key objectives of PS 3251 are to:

  • Eliminate deferral and smoothing mechanisms
  • Improve transparency of employee benefit obligations
  • Enhance comparability across public sector entities
  • Provide clearer information to financial statement users about risk and uncertainty

Effective date and transition

  • Effective date: Fiscal years beginning on or after April 1, 2029
  • Early adoption: Permitted
  • Transition: Retroactive application allowed, with certain transitional reliefs, including no requirement for prior period restatement, and no requirement to provide comparative information for the periods prior to adoption with respect to the new sensitivity analysis of each significant actuarial assumption.

Entities may elect to reflect the cumulative transition impact in accumulated remeasurement gains and losses, for periods prior to the earliest comparative period presented.

Although the effective date is several years away, entities with defined benefit pension plans or other post‑employment benefits should begin assessing impacts now.

Key changes from previous standards

Immediate recognition of remeasurements

Under PS 3251, deferral and amortization of actuarial gains and losses are eliminated:

  • Actuarial gains and losses, together with the return on plan assets excluding amounts included in net interest, are recognized immediately.
  • Amounts are recorded as remeasurements of the net defined benefit liability (asset) in accumulated remeasurement gains and losses.
  • Remeasurements are not reclassified to annual surplus or deficit in future periods.
  • Employee benefit obligations will be more responsive to changes in economic and demographic conditions.

Full balance sheet recognition

Plan assets must be measured at fair value (generally market value) at the measurement date.

The net defined benefit liability (or asset) is recognized on the statement of financial position. Amounts previously deferred or smoothed under prior standards, such as unamortized actuarial gains and losses, will now be reflected directly in reported balances.

The net defined benefit liability (or asset) is limited by the asset ceiling which is similar to the valuation allowance under the prior standards.

This change may result in larger reported liabilities (or assets) at transition and increased volatility in net assets thereafter.

Discount rate framework based on funding status

PS 3251 introduces a funding-status-based approach to setting discount rates for defined benefit plans.

At each fiscal year-end, entities must assess whether a plan is fully funded or underfunded. This assessment can be complex and often requires professional judgement and a careful review of the evidence supporting the plan’s circumstances. The result determines the discount rate used to measure the benefit obligation.

  • Fully funded plans:
    Apply a discount rate that approximates the expected market-based return on plan assets, based on market expectations at the reporting date, taking into account the investment policy of the fund. In practice, this rate may be similar to the discount rate used in a funding valuation.
  • Underfunded plans:
    Apply a discount rate determined by reference to market yields on government bonds or other appropriate high-quality instruments, consistent with the timing and currency of expected benefit payments. In practice, this is likely to be interpreted as provincial government bonds where a deep market exists.

Funding status must be reassessed annually and supported by appropriate documentation.

Enhanced disclosure requirements

PS 3251 significantly expands disclosure requirements, including:

  • Plan characteristics, risks, and funding arrangements
  • Key actuarial assumptions and methodologies
  • Reconciliations of benefit obligations and plan assets
  • Sensitivity of benefit obligations to changes in key assumptions

Joint and multi‑employer plans

  • Joint defined benefit plans:
    Entities recognize their proportionate share of the defined benefit obligation, plan assets, and costs using defined benefit accounting, where sufficient information is available.
  • Multi‑employer plans:
    Public sector entities participating in multi-employer defined benefit plans are required to account for a proportionate share of the plan using DB accounting. Defined contribution accounting may continue to be used only where sufficient information is not available to apply DB accounting, with enhanced disclosures explaining that conclusion.

Early measurement dates

Under PS 3250, entities were permitted to use early actuarial measurement dates with roll-forward adjustments, allowing benefit obligations to be measured several months before year-end. PS 3251 requires employee benefit obligations to be measured as of the financial statement date, using assumptions that reflect conditions at that date. Entities that previously relied on early measurement dates should expect to move toward year end actuarial measurements.

Short-term employee benefits

PS 3251 largely confirms existing practice for short-term employee benefits such as vacation, sick leave, and short-term bonuses, but provides clearer guidance on when these obligations must be recognized, including:

  • Short-term benefits as employees earn them, not when they are paid
  • Accrued absences (such as vacation that carries forward) based on expected usage or payout
  • Short-term bonuses and incentive payments accrued over the period of service, once a present obligation exists and the amount can be reasonably estimated

While these changes are not expected to materially alter benefit obligations, they may result in earlier or more consistent recognition of some short-term liabilities and reduced diversity in practice across entities.

Managing discount rate volatility

A key concern is the potential for frequent changes in funding status classification, which could result in plans switching between discount rate methodologies from year to year. These changes could create volatility in reported liabilities and create confusion about results. This contradicts the objective of improving transparency and comparability and may raise questions from auditors, regulators, and financial statement users.

PS 3251 suggests that funding status is not intended to be assessed mechanically or based solely on short‑term market movements. Instead, assessments should consider the weight of all available evidence, including:

  • Primary indicators: formal funding policies, legislative funding requirements, and the most recent actuarial valuation prepared for funding purposes; and
  • Secondary indicators: past practice of corrective action to fund deficiencies, used when primary indicators do not faithfully represent funding status due to temporary volatility or significant subsequent events.

A temporary decline in asset values is not intended to result in a change in the funding status assessment where primary indicators continue to support a fully funded assessment.

Because discount rate determination now depends on funding status, entities should expect greater scrutiny over:

  • How funding status conclusions are reached
  • Consistency of judgments over time
  • Distinguishing short-term volatility from longer term, structural underfunding

Early planning steps may include:

  • Reviewing and clearly articulating funding policies and legislated funding requirements
  • Understanding how funding valuations will support financial reporting
  • Strengthening governance and documentation practices
  • Engaging early with actuaries and auditors

What this means for public sector entities

While PS 3251 does not affect benefit entitlements or funding decisions, it may:

  • Increase reported liabilities and balance sheet volatility
  • Require enhanced governance and documentation around funding status assessments
  • Lead to more detailed disclosures and increased scrutiny from auditors, boards, and stakeholders
