Life Annuities in Retirement: The Insurance You Can't Outlive

What Is a Life Annuity?

A life annuity is a contract between you and an insurance company. You hand the insurer a lump sum — often drawn from an RRSP, a RRIF, or a non-registered account — and in return, the insurer promises to pay you a fixed monthly income for the rest of your life. Whether you live to 80 or to 105, the payments keep coming. That's why annuities are often called "longevity insurance": they transfer the risk of outliving your assets to the insurer.

In Canada, annuities are insurance products sold exclusively by licensed life insurance companies, regulated at the federal and provincial level. The monthly payout you receive depends mainly on three factors: the amount of capital you contribute, your age at purchase, and prevailing long-term interest rates at the time of the contract.

The Main Types of Annuities

Not all annuities are alike. Here are the most common forms available in Canada:

• Straight life annuity: payments last until your death and stop immediately after. Payouts are the highest of any type, but your estate receives nothing if you die shortly after purchase.
• Life annuity with guaranteed period: if you die before the guarantee period ends (commonly 10 or 15 years), payments continue to your beneficiaries until that period is up. Payouts are slightly lower in exchange for that protection.
• Joint-and-survivor annuity: payments continue to your spouse or partner after your death, often at 60 % or 100 % of the original amount. This is ideal for couples who both depend on the same income stream.
• Term-certain annuity: pays income for a fixed number of years regardless of whether you survive. This isn't true longevity insurance, but it can bridge a gap — for example, before CPP or OAS kicks in at a later age.

The Upside: Security, Simplicity, Zero Market Risk

The core appeal of an annuity is total predictability. You know exactly what arrives in your account every month — no stock-market gyrations, no rebalancing decisions, no sequence-of-returns anxiety. For retirees whose essential expenses (housing, groceries, prescriptions) exceed what CPP and OAS can cover, an annuity fills that gap permanently.

It also eliminates sequence-of-returns risk — the phenomenon where withdrawals made during a market downturn compound losses and permanently impair a portfolio. With annuity income, you never have to sell assets at a low to fund living expenses. The income floor holds regardless of what markets do.

The Downside: Locked-In Capital, Interest-Rate Sensitivity, and No Flexibility

The trade-off is real. Once you sign the contract, the capital is permanently transferred to the insurer. You cannot retrieve it for an unexpected expense — a medical bill, a home repair — nor pass it on in full to your heirs. The exchange is security for flexibility.

Interest-rate sensitivity is another critical reality. Annuities are priced off long-term bond yields: when rates are high, the monthly payment for a given lump sum is more generous; when rates are low, the payout is thinner. The timing of your purchase can therefore meaningfully affect value — which is why some advisors recommend laddering annuity purchases over several years rather than making one large commitment at a single point in time.

Finally, standard annuities do not automatically protect against inflation unless you specifically opt for an indexed version — which reduces the initial monthly payment in exchange for future purchasing-power protection.

The Annuity as One Piece of the Puzzle: Flooring Essential Expenses

Most decumulation specialists don't recommend annuitizing an entire portfolio — they recommend partial annuitization. The logic is straightforward: identify your non-negotiable monthly expenses (rent or mortgage, food, transportation, medication), then check whether CPP + OAS covers them fully. If there's a shortfall, a life annuity can close that gap permanently.

The remaining portfolio — earmarked for discretionary spending, travel, leisure, and estate goals — stays invested under a flexible drawdown strategy (such as the 4% rule). This combination gives you a guaranteed income floor and growth potential for everything above it. You're not betting everything on a single approach: the annuity handles survival risk, and the portfolio handles purchasing power and legacy.
