Workplace pensions: DB vs DC

A defined benefit (DB) pension pays a formula-based income for life and the employer carries the investment risk. A defined contribution (DC) pension builds a pot you invest and later convert to income (annuity, LIF, or RRIF) — you carry the risk. Both reduce your RRSP room via the pension adjustment, and both are taxable, splittable pension income in retirement.

Most Canadian workplace plans fall into two families, with a few hybrids in between:

• Defined benefit (DB): the plan promises a specific monthly pension for life, set by a formula. The employer (and its actuaries) are responsible for funding it, so the investment and longevity risk sit with the plan, not you.
• Defined contribution (DC): the plan defines only what goes in (your and often your employer's contributions). What you end up with depends on contributions plus investment returns, and turning it into lifetime income is your responsibility at retirement.
• Hybrids and targets: some plans combine features (for example a DB base plus a DC layer), and target-benefit or multi-employer plans aim for a benefit but can adjust it if funding falls short.

A DB pension is typically calculated from a formula such as: years of service × an accrual rate (often around 1.5%–2%) × your average pensionable salary (best-five-years or final-average). Thirty years of service at a 2% accrual on a $80,000 average salary, for instance, points to roughly 60% of salary as a lifetime pension.

Three features change a DB pension's real value dramatically:

• Indexing. Whether the pension rises with inflation — fully, partially, or not at all — is the single biggest driver of its long-run worth. An unindexed pension loses purchasing power every year.
• The bridge benefit. Many DB plans pay an extra “bridge” from early retirement until age 65, designed to approximate CPP, then reduce once CPP is expected to start. Know whether your quoted pension includes a bridge that will later drop.
• Early-retirement reduction. Starting a DB pension before its normal retirement date usually reduces it, though some plans offer unreduced early retirement once age-plus-service milestones are met.

In a DC plan you and (usually) your employer contribute a percentage of pay into an account you invest. There is no promised income — your retirement depends on how much went in and how the investments performed. Always contribute at least enough to capture the full employer match; it is an immediate, guaranteed return.

At retirement, a DC balance (like a locked-in LIRA from a former plan) is converted to income, typically through one or more of:

• A LIF (Life Income Fund) — the locked-in equivalent of a RRIF, with a minimum and a maximum annual withdrawal.
• An annuity — trading the balance for guaranteed lifetime income, which converts a DC pot into something closer to a DB pension.
• Sometimes a transfer to a RRIF, depending on locking-in rules.

A DC plan effectively makes you the pension manager — the 4% rule, sequence-of-returns risk, and withdrawal order all apply to it just as they do to your RRSP.

Not every employer plan is a registered pension plan. Two common alternatives behave more like personal savings:

• Group RRSP: an employer-administered RRSP, often with matching. It uses your personal RRSP room and is not locked in, so it is more flexible (and more portable) than a pension.
• Deferred Profit Sharing Plan (DPSP): an employer-only contribution plan tied to company profits; employer contributions create a pension adjustment and are usually locked in until you leave.

Because pensions are tax-assisted, the system prevents double-dipping through the pension adjustment (PA). Your PA — the value of the pension benefit you earned that year (or the total DC/DPSP contributions) — reduces next year's RRSP room. That is why pension members have less RRSP room than non-members at the same income. It is not a penalty; it reflects that your pension is already building tax-sheltered retirement savings. See RRSP vs TFSA for where any remaining room should go.

DB pensions include survivor protection: by law a pension for a member with a spouse is normally paid as a joint-and-survivor pension (a percentage continues to the surviving spouse) unless the spouse waives it. Choosing a higher survivor percentage lowers the monthly amount but protects a partner. A DC or locked-in account passes its remaining balance to a beneficiary or the estate. These choices interact with CPP survivor benefits and estate planning, so weigh them together.

When you leave an employer before retirement with a DB pension, you usually face a one-time, often irreversible choice:

• Keep the deferred pension. Leave it in the plan and collect the promised lifetime income later. Simplest, and it keeps the longevity/investment risk with the plan — attractive if the plan is well-funded and indexed.
• Take the commuted value. Transfer a lump sum out — part to a locked-in account (LIRA), with any excess above tax limits paid as taxable cash. This gives control and estate value but puts all the risk on you, and the taxable portion can be a nasty surprise.

This is one of the highest-stakes retirement decisions many people make, and it is worth professional advice specific to your plan.

A pension changes the whole plan. A generous indexed DB pension can cover most essential spending, which means your personal savings are for flexibility and extras — and it makes you far more likely to face the OAS clawback, so pension income splitting and TFSA use matter more. A DC pension, by contrast, behaves like a large RRSP and needs the same drawdown planning. Enter your expected pension in the cash-flow projection (it supports a DB pension amount and start age) and check the big picture in retirement readiness.
