Summary: Widely quoted withdrawal rules are a reasonable starting point, but their assumptions rarely fit a Canadian founder with a holding company and a 40-year horizon. What you can actually spend depends on how long the money must last, how your spending changes, the timing of CPP and OAS, where your wealth sits for tax and the rules you set for falling markets.
The short answer
Research puts a sustainable starting withdrawal at roughly 3.9% of a portfolio, which is Morningstar’s most recent estimate for a 30-year retirement with a 90% probability of the money lasting. For a Canadian founder or incorporated retiree, that figure is a starting point rather than an answer. It assumes a 30-year horizon, US market data, no advisory fees and wealth held entirely in personal accounts, and almost none of those assumptions fit someone who sold a business in their fifties and holds most of their capital in a holding company.
The number that actually applies to you comes from five things: how long the money has to last, how your spending will change, what guaranteed income you will receive, how your wealth is structured for tax, and the rules that govern how you invest and adjust when markets fall. The last two are where Canadian business owners most often leave spending capacity on the table.
Why a large portfolio can still feel fragile
Many of the people we work with spent decades building wealth that arrived as salary, dividends or business growth. When that stops, the portfolio becomes the only engine, and even eight or ten million dollars can start to feel finite in a way it never did while it was being earned. The instinct is to underspend, and that is often the costliest mistake of all, because the years in which spending matters most are the early, active ones.
The remedy is not a bigger number. It is a plan that shows, year by year, what the capital can support and what would have to change before that stopped being true.
What determines how much I can spend each year?
Five variables do most of the work:
How long the money needs to last
How your spending will change over time
What guaranteed income you will receive, and when
Where your wealth is held and how each dollar is taxed on the way out
How the portfolio is invested, and the rules for adjusting spending when markets fall
The first three describe your life and the last two describe your money. The portfolio should be built around what it has to do, not the other way around.
How long does my money need to last?
Longer than most people plan for. FP Canada’s 2026 Projection Assumption Guidelines recommend planning to an age where the chance of outliving your capital is no more than 25%. On the mortality tables those guidelines use, a 60-year-old man has a one-in-four chance of reaching 94 and a 60-year-old woman of reaching 96, and for a 60-year-old couple there is a one-in-four chance that at least one of them reaches 98.
For a founder who sells at 58, that is a horizon of close to 40 years, not the 30 behind most withdrawal research. A longer horizon lowers the sustainable starting withdrawal, and it argues for holding more growth assets than intuition suggests, because the money that will fund spending in your nineties is money that will stay invested for decades.
Running short late in life is far harder to repair than finishing with a surplus. That asymmetry is why the horizon comes first.
Will my spending stay the same in retirement?
Rarely. David Blanchett’s research on how retirees actually spend found that real spending tends to decline through most of retirement before rising again late in life as health and care costs increase, a pattern now widely known as the retirement spending smile. The early years of travel and projects are usually the most expensive, and they are also the years in which an overly cautious plan costs the most in experiences that cannot be put off.
Large one-off amounts sit outside any annual figure: helping a child buy a home, a renovation, a significant gift or a recreational property. These are better modelled as separate, dated outflows than folded into an average, because their timing interacts with markets and with tax.
Care costs deserve their own line. Private home care or a private-pay residence in BC costs considerably more than a publicly subsidized bed, and the plan should show where that money would come from, whether the portfolio, the home or insurance.
How do CPP and OAS affect what I can spend?
Every dollar of guaranteed, inflation-indexed income is a dollar the portfolio does not have to provide, and CPP and OAS are the only indexed lifetime income most retirees have. Their timing is also one of the few spending decisions that cannot be undone.
CPP is reduced by 0.6% for each month it starts before 65, up to 36% at 60, and increased by 0.7% for each month it is deferred past 65, up to 42% at 70. OAS increases by 0.6% for each month of deferral, up to 36% at 70, and rises a further 10% at age 75. Deferral is in effect the least expensive inflation-protected longevity insurance available, and it is most valuable for people who expect to live long and can fund the intervening years from the portfolio.
Two points matter particularly for business owners. Founders who paid themselves mainly in dividends often have modest CPP entitlements, since dividends do not earn CPP credits, so the benefit may play a smaller role than they assume. And when OAS is likely to be clawed back regardless, the case for deferring it changes entirely, which makes the tax structure discussed below the deciding factor.
Defined benefit pensions, rental income and payments still owed from a sale belong in the same income map. Investments held in a holding company do not. They are part of the portfolio, and dividends drawn from them are withdrawals rather than outside income. Counting them twice is one of the most common errors in retirement projections for incorporated clients.
Where your wealth sits decides what you can spend
You spend after-tax dollars, and most of our clients hold wealth in four or five places that are each taxed differently on the way out: a holding company, RRSPs or RRIFs, TFSAs, non-registered accounts and, for some, an individual pension plan. Two households with the same net worth can have meaningfully different spending capacity purely because of where that wealth sits and the order in which it is drawn.
The holding company. Investment income inside a Canadian-controlled private corporation in BC is taxed at roughly 50.67%, of which 30.67 percentage points is refunded when taxable dividends are paid. The capital dividend account, built from the non-taxable half of capital gains and from life insurance proceeds, can be paid out tax-free. Eligible dividends are taxed more lightly than non-eligible dividends but carry a larger gross-up. The right mix in any year depends on which tax accounts the corporation holds and what else is on your personal return.
RRSPs and RRIFs. An RRSP must be converted to a RRIF by the end of the year you turn 71, and minimum withdrawals then start at 5.28% and rise each year. RRIF income qualifies for pension income splitting with a spouse from age 65. A RRIF left at death without a spouse to roll it to is fully taxable on the final return, often at the top rate, which is why drawing it down deliberately in the years before minimums and OAS begin frequently lowers lifetime tax.
TFSAs. Withdrawals are tax-free, do not count toward the OAS recovery tax and restore contribution room the following year. Because a TFSA grows tax-free and passes tax-free at death, it is often the last account drawn on.
The OAS recovery tax. OAS is reduced by 15% of net income above $95,323 for 2026. For a holding company owner the trap is the dividend gross-up, because the income that counts is the grossed-up dividend rather than the cash received. Capital dividends and TFSA withdrawals do not count at all.
An illustration
Consider a hypothetical couple, both 66, each drawing $120,000 a year in personal cash flow from their holding company, with no other income for simplicity. The cash is identical in each case. The result is not.
| How each spouse draws $120,000 | Income reported for OAS | OAS recovery tax (each) |
|---|---|---|
| $120,000 of non-eligible dividends | $138,000 | About $6,400 |
| $120,000 of eligible dividends | $165,600 | About $10,500, more than a full year of OAS, so the pension is lost |
| $60,000 capital dividend and $60,000 of eligible dividends | $82,800 | None |
The capital dividend account is finite, and the corporation’s refundable tax balances also influence which dividends make sense in a given year, so the best mix changes over time. But the type and order of withdrawals is a planning decision worth thousands of dollars a year, every year, and it is invisible to any rule of thumb.
Illustrative only. Uses 2026 dividend gross-up rates (15% non-eligible, 38% eligible) and the 2026 OAS recovery threshold of $95,323. Actual results depend on the corporation’s tax accounts, other income and personal circumstances.
How do markets affect what I can spend?
The order of returns matters as much as their average. A decline in the first few years of withdrawals does far more lasting damage than the same decline a decade later, because assets sold at depressed prices to fund spending are no longer there when markets recover. This is sequence of returns risk, and it is the main reason withdrawal research produces conservative starting rates.
Three tools manage it. A liquidity reserve holding two to three years of planned withdrawals in short-term, high-quality assets means the growth portfolio is never sold into a falling market to pay the bills. Spending rules, such as the guardrails approach developed by Jonathan Guyton and William Klinger, set in advance how much spending is trimmed after a poor year and restored after a strong one, and their research found that rules of this kind support a higher starting withdrawal than a fixed, inflation-adjusted amount. And the asset mix should reflect the horizon: FP Canada’s 2026 guidelines project long-term returns of 3.2% for fixed income against 6.3% to 7.5% for equities, before fees, so a 40-year plan funded mostly by bonds can carry more risk of running short than one with enough equities to keep pace with inflation.
The behavioural side matters as much as the mechanics. A plan agreed in calm markets, with its adjustments written down, is far easier to follow during a drawdown than one improvised in the middle of it.
Costs belong in the same conversation. Every percentage point of fees comes directly out of the return that supports withdrawals, so a plan built on gross returns overstates what can be spent. The FP Canada assumptions are stated before fees for exactly that reason.
Does the 4% rule work in Canada?
The 4% rule comes from William Bengen’s 1994 research and the Trinity study that followed, which found that withdrawing 4% of a portfolio in the first year and raising the amount with inflation would have lasted through every 30-year period in US market history. It remains the most quoted figure in retirement planning, and Morningstar’s current estimate of 3.9% sits close to it.
For a Canadian founder, four of its assumptions break down. The horizon is often closer to 40 years than 30. The research ignores fees. It assumes spending rises in a straight line with inflation, which the spending smile contradicts. And it treats the portfolio as a single personal account, with no holding company, no RRIF minimums, no OAS recovery tax and no pension income splitting.
A rule of thumb is a useful sanity check. It cannot tell an incorporated household with a 40-year horizon what it can spend.
What makes the calculation more complex?
You want to leave a specific legacy. A target for children or charity is a claim on the portfolio that reduces lifetime spending, unless it is funded another way. Permanent life insurance owned by the holding company can fund the legacy directly, and most of the death benefit can then be paid out tax-free through the capital dividend account, which often allows the portfolio itself to support a higher level of spending during your lifetime.
You support family members. Regular help for children, grandchildren or parents tends to last longer and cost more than expected. Income earned on money given to a spouse or minor child can be attributed back to you, and dividends paid to family members from the holding company can fall under the tax on split income. Planned gifts made early are often easier to manage than open-ended support.
Much of your wealth is illiquid. A principal residence, a recreational property or a residual business interest can represent a large share of net worth while producing no income. The plan should be explicit about whether the home is a reserve to draw on, through downsizing or in some cases a reverse mortgage, or an asset to keep.
You are most concerned about living a very long time. An annuity converts part of the portfolio into guaranteed lifetime income, and an advanced life deferred annuity allows up to $180,000 of registered savings to be set aside for income starting as late as 85. Neither suits everyone, but both address directly the risk this question is about.
There is a US connection. Time spent in the US can create US filing obligations under the substantial presence test, US real estate and securities can be exposed to US estate tax, and US citizens face a second tax system on everything they withdraw. Any of these can change both the tax on withdrawals and the best order in which to take them.
In each case, a spending plan works best when your accountant, lawyer and portfolio manager are working from the same picture.
Where Westmount starts
Westmount Wealth Management is a Canadian portfolio manager with offices in Vancouver, Qualicum Beach and Toronto. It is registered in BC, Alberta, and Ontario and provides discretionary portfolio management to founders during and after a business sale, as well as to incorporated and asset-rich retirees.
We build spending plans the way this article describes: a year-by-year cash flow across every entity the family owns, a draw order designed to keep lifetime tax and OAS recovery as low as possible, a liquidity reserve sized to protect against an early downturn, and spending rules agreed in advance. We review the plan at least once a year and whenever something significant changes. The first conversation is a discovery meeting to understand what you want the money to do and how it is structured today.
Frequently asked questions
How much can I spend each year from an $8 million portfolio?
As a rough starting point, an initial withdrawal of 3.5% to 4% would suggest $280,000 to $320,000 a year before tax. For an incorporated household, the after-tax amount can vary widely depending on how the wealth is split between the holding company and registered and personal accounts, the draw order, the time horizon and whether OAS is preserved. A cash flow plan replaces the estimate with a figure specific to you.
When should I start CPP and OAS?
Deferring CPP to 70 increases it by 42%, and deferring OAS to 70 increases it by 36%, in both cases indexed to inflation for life. Deferral generally makes sense for those in good health who can fund the intervening years from the portfolio. Starting earlier can make sense where health is a concern, or where a small CPP entitlement or an expected OAS clawback reduces the value of waiting.
How does inflation affect how much I can spend?
A plan should use an explicit inflation assumption, and FP Canada’s 2026 guideline is 2.1% a year. CPP, OAS and some defined benefit pensions are indexed, while most other income is not, and some costs, care in particular, have tended to rise faster than general inflation. Projections are easiest to read in today’s dollars, but the assumptions behind them should be stated.
How often should I review my spending plan?
At least once a year and after any significant event: a sale, a move, a change in health, a large market decline or a change in family circumstances. Annual reviews allow small adjustments early instead of large ones later, and they are where the spending rules agreed in advance are applied.
Why do I feel uneasy spending, even with significant savings?
It is common among people who built their wealth through discipline and reinvestment, and moving from accumulating to spending is a genuine psychological shift. A plan that shows what the capital can support, and what would have to happen before spending needed to change, usually does more to ease that unease than a larger balance would.
