DB vs DC pensions

If you work in mining, energy, utilities, government, a university, or established manufacturing, your pension may be the single largest asset on your balance sheet — and the least understood. The first thing to know is which type you have, because they’re almost opposite in how they work.

Defined Benefit (DB)

The employer promises a formula-based income for life, typically something like:

annual pension = 2% × years of service × best-average salary

So 30 years at a $130,000 average salary → roughly $78,000/yr for life. The employer (and its actuaries) bear the investment and longevity risk — if markets fall or you live to 100, that’s their problem, not yours.

• Pros: guaranteed income, no decisions, often partially indexed to inflation, sometimes includes a bridge benefit to age 65.
• Cons: illiquid, tied to your employer, limited estate value (often ends with you and a surviving spouse), and you have little control.

Defined Contribution (DC)

You and your employer contribute a set amount (say 5% + 5%); the balance grows in investments you choose. Your retirement income depends entirely on contributions and market returns. It behaves much like a group RRSP.

• Pros: portable, transparent, full control, and a real estate asset — whatever’s left is yours to leave behind.
• Cons: you bear the investment and longevity risk. A bad sequence of returns near retirement lands on you.

	Defined Benefit	Defined Contribution
Who bears investment risk	Employer	You
Retirement income	Known formula	Depends on markets
Portability	Low (or take commuted value)	High
Inflation indexing	Sometimes	Only if you build it
Estate value	Limited	Full remaining balance
Decisions required	Few	Many (allocation, drawdown)

What it means for the rest of your plan

• A DB pension acts like a big bond / annuity. It’s a stable income floor, so you can often afford to hold more equities in your RRSP/TFSA than someone without one — the pension is your fixed income.
• A DC plan is your money to manage. Treat it as part of your total portfolio, watch the fund fees inside it (group plans aren’t always cheap), and don’t leave it in a default target-date fund without checking the cost.
• Job-hopping? Engineers and geoscientists who move between projects and employers should understand vesting and what happens to a DB pension when you leave — which leads to the biggest decision of all.

The decision most DB members eventually face

If you leave a DB plan before retirement, you’ll often be offered a choice: keep the deferred pension, or take its commuted value as a lump sum. That call is large and irreversible — see The commuted value decision.

Checklist

• Confirm whether my plan is DB, DC, or a hybrid.
• For DB: find the formula, indexing terms, bridge benefit, and survivor options.
• For DC: check the contribution match and the fees on the funds I hold.
• Factor the pension into my overall asset allocation, not in isolation.
