The RRSP Meltdown Window: A Complete Guide for Ontario Retirees Aged 60–71

A married couple in London, Ontario walks into a planning meeting at 62. They've just retired. Between them they have $1.2 million in RRSPs, a paid-off house, and a small TFSA. They feel set. They're not yet collecting CPP or OAS, and they figure they'll start at 65.

Their plan is to "let the RRSPs grow." It's the worst thing they can do.

By the time they're 71, those RRSPs — converted to RRIFs and growing at a modest 5% a year — will force them to withdraw roughly $85,000 a year, every year, fully taxable, on top of whatever CPP and OAS they've started. The OAS will get clawed back almost in full. Their marginal tax rate, voluntarily zero today, will be sitting above 35%. And the forced withdrawals will keep climbing every year until one of them dies — at which point the surviving spouse inherits the whole RRIF at a single, brutal tax rate.

Almost all of that pain is avoidable. The RRSP meltdown is the planning move that avoids it. This is a complete guide for Ontarians sitting in that 60-to-71 window — what the strategy is, why the timing matters, the math behind it, and the four most common ways people get it wrong.

What an RRSP meltdown actually is

An RRSP meltdown is the practice of deliberately and gradually withdrawing money from your RRSP during the years between retirement and age 71 — sized each year to keep your marginal tax rate as low as possible.

A few things it is not. It is not "cashing out" the RRSP — which would put the entire balance into one tax year and trigger the top marginal rate (53.53% in Ontario on amounts above $246,752 in 2026). It is not a product, a special account, or anything you "sign up" for. It is not aggressive tax planning. It is simply paying the tax on RRSP money now, at the rate you've chosen, instead of later, at the rate the government chooses for you.

The strategy works because of one structural feature of the Canadian tax system: at age 71, every RRSP in the country is forced to convert to a RRIF, and a RRIF carries a mandatory minimum withdrawal that climbs every year for the rest of your life. You don't control the amount, you don't control the timing, and you pay tax on it at whatever your marginal rate happens to be that year. If that rate is high because of CPP, OAS, a pension, and forced RRIF income piled together — and for many Ontarians it will be — the lifetime tax cost is enormous.

The meltdown moves that tax payment forward into years where you control the marginal rate. That's it. That's the whole strategy.

Why the 60-to-71 window matters most

The window exists because three independent forces line up in your favour during those years — and only during those years.

First, you've stopped earning employment income. For most retirees this drops marginal tax rates from 30%+ down to roughly 20–24% in the lower brackets, simply because there's no salary on the return.

Second, you haven't started CPP or OAS yet — or you've started just one of them at the standard age of 65. Every year you defer CPP past 65 boosts it by 8.4% permanently (up to a maximum of 42% if you defer all the way to 70). Every year you defer OAS past 65 boosts it by 7.2% permanently (up to 36% at 70). Those increases are inflation-indexed for life. Which means the years you're meltdown-eligible are also the years you have the most to gain from delaying government benefits.

Third, you haven't hit the RRIF minimum withdrawal cliff at 71. Right now, every dollar you pull from the RRSP is a dollar you chose to pull. Once 71 hits, that ends.

For most Ontarians, the sweet spot inside the window is 65 to 71. Before 65 you don't get the federal pension income tax credit (which lets you offset a small amount of RRIF/annuity income against tax owed). After 71 you've lost control of the throttle. The five years from 65 to 71 are where you can withdraw, claim the credit, split income with a spouse, and still control the size of each withdrawal — all at the same time.

The math, with real Ontario numbers

Take that London couple again. Both 62, $1.2M combined RRSP, planning to start CPP and OAS at 65.

Path A: do nothing during the window. RRSPs compound at 5% a year. By 71, the combined balance is roughly $1.6M. The minimum RRIF withdrawal at 71 is 5.28% — about $85,000 a year, fully taxable. Layered on top of their CPP/OAS, that pushes their household income above $130,000. They lose virtually all of their OAS to clawback. Their marginal tax rate on those forced withdrawals sits around 35%. Over the next 20 years of forced withdrawals — which keep climbing as the RRIF minimum percentage rises with age — they pay approximately $680,000 in lifetime tax on RRIF income alone.

Path B: meltdown $50,000 each per year from 62 to 71. That's $100,000 a year of household RRSP withdrawals during their low-income years. Split between two spouses, it lands at roughly the 24% marginal bracket in Ontario for each. The 10-year tax cost: about $240,000. The withdrawn money funds their living expenses, which lets them defer CPP and OAS to 70 — adding 42% and 36% respectively to those payments, indexed for life. By 71, their RRIF balance is around $700,000 instead of $1.6M. RRIF minimums at 71 are now roughly $37,000 a year. They stay well below the OAS clawback threshold. Their marginal rate stays around 24%.

The lifetime tax savings versus Path A: somewhere between $150,000 and $200,000. The lifetime CPP/OAS gain from deferring to 70: another $200,000 to $300,000 over a 25-year retirement, depending on longevity.

These numbers are illustrative, not personalized. They depend on actual returns, OAS thresholds in future years, longevity, and a dozen other variables. The point is the order of magnitude: the meltdown decision is not a few thousand dollars. It's six figures, sometimes seven, in lifetime difference.

How CPP and OAS timing reshapes the meltdown

The meltdown and the decision of when to start CPP and OAS are not two separate decisions. They are one decision. (For the deeper analysis on CPP specifically, see the companion pillar guide: When to Take CPP in Canada.)

The reason is that the meltdown gives you the cash flow to delay your government benefits. Most Ontarians take CPP at 65 (or earlier) because they "need the money." But if you have RRSP balances in the meltdown window, you don't need the CPP money — you have the RRSP money sitting right there, and pulling it serves two purposes at once: it shrinks your future RRIF base, and it bridges your expenses until CPP and OAS hit their maximum at 70.

Looked at the other way: deferring CPP and OAS only "pays off" if you live long enough to collect the larger benefits. Most Canadians age 65 today have a life expectancy past 85, which is well past the breakeven age (typically around 79–82 for CPP). For couples, where the longer-lived spouse drives the math, the case for deferral is even stronger.

The two strategies — RRSP meltdown plus delayed CPP/OAS — are designed to work together. Doing only one of them often costs you more than doing neither.

Who this fits and who it doesn't

The meltdown is most valuable when all of the following are true:

• Combined RRSP balances of roughly $500,000 or more
• Retirement age between 60 and 65
• Some non-registered or TFSA buffer for cash-flow flexibility
• No large defined-benefit pension that already pushes household income above the OAS clawback threshold

It is not the right call when:

• RRSP balances are small (under $200K — the future RRIF minimums won't trigger meaningful tax)
• You're still earning employment income
• You have a large pension already sitting above the OAS clawback line
• Your spending needs in early retirement are unusually high and require liquid non-registered funds

There's a useful bright-line check: project your RRIF minimum at age 75 assuming 5% annual growth. If that projected minimum exceeds $50,000 a year, and your current marginal tax rate is below 30%, you almost certainly should be melting down. The spread between "now" and "then" is the opportunity.

The four most common mistakes

1. Melting down too aggressively. Pulling enough to push yourself into the 31% bracket today, just to avoid the 35% bracket later, is a 4-point arbitrage on a small slice of income — it rarely justifies the cash-flow drag and lost growth. Stay below the next bracket break.

2. Forgetting the spousal RRSP attribution rule. If you contributed to a spousal RRSP, any withdrawal within three calendar years of the last contribution gets attributed back to the contributing spouse's tax return — usually at a higher rate. Plan contributions and withdrawals around the three-year rule.

3. Not using the TFSA as the destination account. Every dollar of melted-down RRSP money that isn't needed for living expenses should be re-contributed to a TFSA. The TFSA limit is contribution-only — once it's in, future growth and withdrawals are tax-free for life and don't count toward OAS clawback. Most Ontarians have unused TFSA room in retirement.

4. Triggering the OAS clawback by accident. The 2026 recovery threshold is roughly $94,000. Combined RRSP withdrawal + CPP + OAS that pushes household income above that costs 15 cents on the dollar in clawback. The meltdown should be sized to stay below the threshold, not to maximize withdrawal.

How to actually run it

The mechanics are straightforward once the plan is set:

1. Project RRIF minimums at age 75 using a realistic growth assumption (5% real return is standard).
2. Estimate the marginal tax rate at that age, including CPP, OAS, and any pensions.
3. Compare against your current marginal rate. The difference is the per-dollar opportunity.
4. Decide the annual withdrawal amount — usually targeting the top of your current bracket, or the OAS clawback floor, whichever comes first.
5. Withdraw equal amounts from each spouse's RRSP when both have balances. This keeps both spouses in lower brackets rather than pushing one into a higher one.
6. Route the after-tax proceeds first to the TFSA (until both spouses' TFSA contribution room is used), then to a non-registered investment account.
7. Re-evaluate annually. Tax brackets, OAS thresholds, and your portfolio values all change every year.

The decision can be expressed as a single number per year. The plan supporting it shouldn't be more complicated than a one-page schedule.

Working with a planner on this

The meltdown is one piece of a connected retirement plan that also includes CPP and OAS timing, pension income splitting after 65, sequence-of-returns risk in the early years, withdrawal-order rules across RRSP, TFSA, and non-registered accounts, and estate-tax exposure at the second death. Each of those decisions changes the others.

The right meltdown plan for your situation depends on your specific RRSP balances, pension structure, marital status, expected longevity, and risk tolerance — not on a generic rule of thumb.

The 60-to-71 window doesn't last forever, and the cost of missing it climbs every year. The meltdown isn't aggressive tax planning. It's the calm, paced version of a tax bill you're going to pay anyway — paid now at 24%, instead of later at 35%, while keeping your retirement income stable. If you're in your early 60s with substantial RRSP balances, the planning conversation is worth having this year, not next.
