If you have left, or are about to leave, an employer with a defined-benefit (DB) pension, you may be handed a choice that feels deceptively simple: keep the promise of a monthly cheque for the rest of your life, or take a lump sum today and manage it yourself. The dollar figures are large — often seven figures — and the decision is frequently irreversible. Most plans give you a set window, commonly 60 to 90 days after your departure, to decide. That combination of size, permanence, and a ticking clock is exactly why it deserves careful, unhurried thought rather than a rushed signature.
What a commuted value actually is
Your DB pension promises a defined income for life — say, a set percentage of your final salary for every year you worked. The commuted value (CV) is the plan actuary's estimate, in today's dollars, of what that lifetime stream of payments is worth as a single lump sum. It is calculated using prescribed interest rates and standardized mortality assumptions.
Because the calculation is rate-sensitive, the number moves. When long-term interest rates are low, commuted values are high; when rates rise, commuted values fall — sometimes materially, from one quarter to the next. The 2022–2024 rate increases pushed many CVs down meaningfully from their pandemic-era peaks. So the figure on your statement is a snapshot, not a fixed entitlement.
The core trade-off
Strip away the jargon and the decision is about who bears the risk.
Keep the monthly pension, and the plan sponsor carries the investment risk, the longevity risk (the risk you live to 100), and the administrative burden. You receive a predictable, usually inflation-adjusted-or-partially-indexed income you cannot outlive. In exchange, you give up control and flexibility: you cannot access the capital, adjust the timing, or leave the full value to your children.
Take the commuted value, and it transfers into locked-in accounts you control — a LIRA (Locked-In Retirement Account) or LIF, depending on the jurisdiction. Now you carry the investment and longevity risk, but you gain control, drawdown flexibility, potential estate value, and the ability to coordinate the money with the rest of your plan. The upside is real; so is the responsibility.
Neither option is universally "right." The honest answer depends on your health, your other assets, your family situation, and your temperament.
The tax trap most people miss: the maximum transfer value
Here is the detail that surprises people. When you elect the commuted value, the Income Tax Act limits how much can move into your locked-in account on a tax-sheltered basis. This ceiling is the Maximum Transfer Value (MTV), set by an age-based formula.
The portion of your CV up to the MTV transfers into the LIRA tax-deferred. Any excess above the MTV cannot go into the LIRA — it is paid to you as cash and is fully taxable as income in the year you receive it. For a large commuted value, that excess can be substantial, and it can land you in the top marginal bracket for a single year.
There are ways to soften the blow — using available RRSP contribution room to shelter part of the excess, or timing your departure so the taxable portion falls in a lower-income year. But these moves require planning before you elect, not after. Once the money is paid out, the options narrow quickly.
A hypothetical worked example
The following is illustrative only. It is not a projection, a recommendation, or a promise of any outcome.
Consider a hypothetical executive, 58, offered a choice: a $10,000/month pension (partially indexed, with a 60% survivor benefit) beginning at 65, or a $1.1 million commuted value today.
- Suppose the age-based MTV formula shelters roughly $780,000 into her LIRA.
- The remaining ~$320,000 is paid as taxable cash. If she has $120,000 of unused RRSP room, she might shelter that portion, leaving roughly $200,000 taxable this year — a large but manageable tax bill if it lands in an otherwise lower-income year.
- The sheltered capital is then invested and drawn down over her lifetime alongside CPP, OAS, and other assets.
Whether she ends up ahead depends on future returns, how long she lives, and how disciplined the drawdown is — none of which anyone can guarantee. The point of the exercise is not to declare a winner. It is to show that the "$1.1 million" is not $1.1 million in her pocket, and that the after-tax, after-sequencing reality is what actually matters.
Sequencing, CPP/OAS, and drawdown
If you take the commuted value, the LIRA does not sit in isolation — it becomes one lever in a multi-account retirement plan. That opens tax-planning opportunities a fixed pension cannot:
- Bridge years: Drawing modestly from the LIF in your early retirement years can let you defer CPP and OAS to 70, boosting those guaranteed, indexed government benefits by up to 42% and 36% respectively.
- Bracket management: Blending withdrawals across LIF, RRSP/RRIF, TFSA, and non-registered accounts can smooth taxable income and reduce OAS clawback exposure.
- Order of withdrawals: The sequence in which you tap each account can meaningfully change lifetime tax — something you control with a lump sum but not with a pension.
A fixed monthly pension, by contrast, gives you certainty but very little room to manoeuvre around the tax system.
Survivor and estate considerations
This is where the two paths diverge most sharply.
A DB pension typically pays a reduced survivor benefit (often 60%) to a spouse, and then stops. If both spouses pass earlier than expected, the remaining value is gone — nothing passes to children or other heirs. A commuted value transferred to a LIRA remains your capital: whatever is unspent at death forms part of your estate (subject to tax on registered funds). For those with a strong bequest motive, or no spouse, that difference can be decisive. For a couple who simply want secure income and are not focused on leaving a large estate, the pension's guarantee may be worth more than the flexibility.
What this means for you
The monthly pension tends to suit you if: you value certainty above all, you expect a long life and good health, you have limited other assets, and estate value is not a priority.
The commuted value tends to suit you if: you have meaningful other savings, you want control and drawdown flexibility, you plan to defer CPP/OAS, estate or bequest goals matter, or you have health considerations that make lifetime income less valuable to you.
Most importantly: because rates move the CV and the election is usually permanent and time-limited, this is not a decision to leave until the last week of your window. The urgency is genuine, but the right response to urgency is to start the analysis early — not to sign quickly.
As an independent, fee-based fiduciary firm, we have no pension product to sell you and no commission riding on your choice. Our only interest is which path serves your plan. Modelling both options — after tax, after the MTV excess, and integrated with CPP, OAS, and your other accounts — is precisely the work a Second-Opinion Portfolio Review is built for.
