Turning your savings into reliable retirement income is more complex than building them. Decumulation isn’t simply “what do I withdraw?”, it’s coordinating longevity risk, taxes, market volatility, and simplicity. Here are the key considerations for Canadian retirees.

## 1. Start with Lifestyle, Not Accounts

Your withdrawal strategy must reflect the life you want to live. Break spending into:

- Essential: housing, food, utilities, insurance
- Discretionary: travel, entertainment, hobbies
- Occasional: home repairs, vehicles, major health needs

Match guaranteed income (CPP, OAS, pensions) to essentials and use portfolio withdrawals for discretionary spending. Decumulation often fails when withdrawals aren’t anchored to real-life cash flow needs.

## 2. Know Your Income Sources and Tax Treatment

Most retirees draw from several sources:

Ultimately, decumulation is tax planning.

## 3. Protect Against Sequence-of-Returns Risk

Market declines early in retirement can permanently shorten portfolio longevity. To mitigate:

- Maintain an equity allocation that still supports long-term growth
- Keep 2–3 years of withdrawals in cash or short-term bonds
- Rebalance based on rules, not headlines

## 4. Withdrawal Order Matters - But Isn’t One-Size-Fits-All

Patterns that typically work well include:

Done properly, smart sequencing preserves benefits, smooths cash flow, and reduces tax drag.

## 5. Understand the OAS Clawback

Once income exceeds the threshold, each additional dollar reduces OAS by 15 cents, effectively increasing your marginal rate by 15%. Proper planning - especially RRSP/RRIF withdrawals in your 60s - helps avoid paying more tax than necessary.

## 6. Timing CPP and OAS

For many healthy Canadians, delaying CPP (and sometimes OAS) until age 70 offers strong, inflation-protected longevity insurance. Optimal timing should be based on integrated modelling rather than simple breakeven math.

## 7. Keep the Portfolio Working

Retirement may span three decades or more. Going “all GICs” rarely keeps pace with inflation.

A SciVest-style approach maintains:

- Global equity exposure
- High-quality bonds and cash buffers
- Low-cost, diversified ETFs
- Smart asset location across accounts

## 8. Build Flexibility and Simplicity

Effective decumulation incorporates spending guardrails, contingency planning (survivor income, long-term care), and clean, manageable account structures.

## The Bottom Line

A strong decumulation plan is not guesswork, it’s disciplined, evidence-based decision-making that turns lifelong savings into a reliable, tax-efficient income stream. When cash flow, taxes, market risk, and government benefits are coordinated thoughtfully, the result is clarity, confidence, and real peace of mind.
