Quick Answer
A healthy single 65-year-old in Ontario with $750,000 in RRSPs and no defined-benefit pension faces one of the most consequential decisions in Canadian retirement planning: when to start CPP, when to start OAS, and how fast to draw down the RRSP. The default plan most retirees pick — CPP at 65, OAS at 65, RRIF withdrawals starting at 71 — leaves roughly $84,000 of lifetime tax on the table compared to the optimal sequence. The optimal play: defer CPP to age 70 (locking in a 42% larger lifelong cheque under the CPP Act's 0.7%/month enhancement), defer OAS to age 70 (locking in a 36% larger lifelong cheque under the OAS Act's 0.6%/month enhancement), and use ages 65-69 as an RRSP meltdown window — withdrawing $50,000/year while in the lowest possible Ontario marginal bracket (~20-24% combined). This collapses the RRSP balance before the mandatory 5.28% RRIF minimum kicks in at 71, and keeps total income safely below the OAS clawback threshold of $95,323 even into the late 80s. The break-even age is 82 — well inside median Canadian life expectancy. The exceptions matter: terminal diagnosis, family history of <80 lifespan, or a defined-benefit pension already pushing into the top bracket can flip the answer.
Key Takeaways
- 1The 2026 CPP maximum at age 65 is $1,507.65/month ($18,091.80/year). Deferring to 70 locks in a 42% enhancement under the CPP Act (0.7%/month × 60 months) — the maximum cheque rises to $2,141.86/month or $25,702/year. That's an extra $7,610/year of fully-indexed, longevity-protected income for the rest of your life. Break-even versus taking CPP at 65 happens at age 81-82.
- 2The 2026 OAS maximum (age 65-74) is $742.31/month. Deferring to 70 locks in a 36% enhancement under the OAS Act (0.6%/month × 60 months) — the cheque becomes $1,009.54/month or $12,114/year. After age 75, the 10% top-up bumps it further. OAS deferral break-even is also age 82-83.
- 3The OAS clawback (recovery tax under ITA s. 180.2) kicks in at $95,323 of net income in 2026 and claws back 15 cents of every dollar above the threshold. For a single retiree with $750K in RRSPs growing inside the account until 71, the mandatory 5.28% RRIF minimum plus indexed CPP and OAS will breach the clawback threshold in the late 70s — costing $3,000-5,000/year in clawed-back OAS for the rest of life.
- 4The RRSP meltdown strategy: between ages 65 and 69, with no CPP or OAS income and no other taxable income, you can withdraw $50,000/year from the RRSP at a combined Ontario marginal rate of roughly 20-24%. That same $50,000 withdrawn at 75 (stacked on top of CPP, OAS, and RRIF minimums) is taxed at 30-44% and may also trigger OAS clawback. The 5-year window between retirement and CPP/OAS start is the single most valuable tax-planning lever in Canadian retirement.
- 5The TFSA is the bridge. Withdrawing $50K from the RRSP, paying $10-12K of tax, and contributing the remaining $38K to the TFSA (using accumulated 2026 cumulative room of $109,000) shifts after-tax dollars into a never-taxed bucket — and reduces future OAS clawback exposure because TFSA withdrawals don't count as income.

David retires at 65. Toronto, single, never married, no children. Owns his Yonge-and-Eglinton condo outright (worth ~$700,000), $750,000 in RRSPs accumulated over a 35-year career as a mid-senior engineering manager, $80,000 in TFSA, $40,000 in a non-registered chequing/savings bridge. He's eligible for the maximum CPP at 65 (he hit the YMPE cap most years). Eligible for the full OAS at 65. No defined-benefit pension. Healthy, non-smoker, parents both lived past 85.
His question — the one almost every Canadian asks the year they retire: when do I start CPP, when do I start OAS, and how fast do I draw down the RRSP?
Most retirees default to: CPP at 65, OAS at 65, leave the RRSP alone until the mandatory conversion to RRIF at age 71. It's the path of least resistance. It's also the path that leaves roughly $84,000 of lifetime tax on the table compared to the optimal sequence.
The Default Plan — And Why It Costs $84,000
Under the default plan, David starts CPP at 65 ($18,092/year at the 2026 maximum), starts OAS at 65 ($8,908/year), and lets his $750,000 RRSP compound. At 5% nominal growth, the RRSP grows to roughly $1,000,000 by age 71 — at which point the CRA forces conversion to a RRIF and a mandatory minimum withdrawal of 5.28% per year (CRA Regulation 7308, the prescribed factor for age 71).
That's $52,800 of forced taxable income at 71, stacked on top of indexed CPP (~$20,400) and indexed OAS (~$10,000) for a total of $83,200 of net income at 71. Still under the OAS clawback threshold of $95,323. But the RRIF minimum percentage climbs every year — 5.82% at 75, 6.82% at 80, 8.51% at 85. By age 78, David's mandatory income breaches the clawback threshold, and the CRA starts taking back 15 cents of every dollar of OAS.
The OAS clawback trap
Section 180.2 of the Income Tax Act imposes the OAS recovery tax: 15% of every dollar of net income above $95,323 (2026 threshold), up to a full clawback at roughly $155,000. For a default-plan retiree with $750K in RRSPs growing untouched to age 71, the RRIF minimums compound past the threshold in the late 70s and only get worse. By age 85, David is losing ~$3,400/year of OAS to clawback. Cumulative cost over ages 78-90: roughly $30,000-$45,000 of OAS gone — for no reason other than not running the math at age 64.
The Optimal Sequence: Defer CPP and OAS, Melt the RRSP First
The optimal plan has three moving parts that work together. Each one alone is worth thousands; together they compound to the $84,000 lifetime delta.
1. Defer CPP to age 70 (+42% lifelong increase)
The CPP Act gives you a 0.7%/month enhancement for every month you delay CPP past age 65, capped at 42% at age 70. On the 2026 maximum CPP of $1,507.65/month at 65, deferring to 70 produces $2,141.86/month, or $25,702/year — an extra $7,610/year of fully indexed, longevity-protected income for the rest of David's life. The break-even is age 81-82: if David lives past 82, he's ahead on lifetime CPP dollars. His parents both lived past 85, so the actuarial bet is strongly in his favour.
2. Defer OAS to age 70 (+36% lifelong increase)
The OAS Act gives you a 0.6%/month enhancement for every month you delay OAS past age 65, capped at 36% at age 70. On the 2026 maximum OAS of $742.31/month at 65-74, deferring to 70 produces $1,009.54/month, or $12,114/year. After age 75, the 10% OAS top-up applies on top of the deferred amount — bringing the deferred-OAS cheque above $1,110/month at age 75+.
Unlike CPP, OAS isn't funded by your contributions — it's funded from general government revenue. So the deferral decision is purely an actuarial bet: do you live past 82-83? For a healthy 65-year-old non-smoker, median life expectancy is well past that. Defer.

3. The RRSP meltdown: $50,000/year for 5 years at 20-24% marginal rate
Here's the move most retirees miss. With no CPP, no OAS, and no employment income between ages 65 and 69, David's only taxable income comes from the RRSP withdrawal itself. Withdrawing $50,000/year places him in Ontario's combined marginal bracket of roughly 20-24% (he stays under the federal first-bracket threshold and the Ontario surtaxes don't kick in until ~$112K). Total tax on each $50,000 withdrawal: approximately $10,000.
Compare that to the same $50,000 withdrawn at age 75, stacked on top of indexed CPP (~$22,000), indexed OAS (~$11,000), and a RRIF minimum (~$60,000): total income $143,000+, marginal rate 30-44%, tax on the $50,000 withdrawal: $15,000-$22,000 — plus $7,000+/year of OAS clawback. Same dollars out of the same account, taxed differently because of when they leave.
Over 5 years (ages 65-69), David melts down $250,000 of RRSP at a blended 20-22% marginal rate, paying roughly $50,000 in total tax. The remaining $200,000 of after-tax cash funds his living expenses (~$40,000/year is enough for a Toronto retiree with a paid-off condo) and tops up his TFSA (~$36,000 of accumulated room used in year 1, then $7,000/year of annual room).

Where the Sequence Fails: 3 Scenarios That Flip the Answer
The CPP-OAS-RRSP sequence is the right answer for most single retirees in Ontario with $300K-$2M in RRSPs and no defined-benefit pension. It's the wrong answer in three specific situations.
- You have a defined-benefit pension above $80,000/year. A retired teacher with $90,000 of OTPP income or a federal civil servant with $95,000 of PSPP income is already in the 30%+ marginal bracket at 65. There's no "low-income window" to exploit. The meltdown adds tax at high rates instead of low ones. For DB-pension retirees, the better play is usually: take CPP at 65, defer OAS to 70 separately (it's a different decision), and stretch RRIF minimums.
- Terminal diagnosis or family history of life expectancy under 80. The deferral is an actuarial bet, and the break-even is age 82-83. If you're unlikely to live past 80, take both benefits at 65 — the cash-in-hand of the smaller cheque outweighs the larger cheque you may not collect.
- You qualify for GIS. The Guaranteed Income Supplement claws back at 50% per dollar — steeper than the OAS clawback's 15%. For a retiree with a small RRSP ($100K-$200K) and limited CPP, the meltdown would entirely disqualify GIS for those years — usually costing more than the marginal-rate savings.
The Decision Lever That Mattered
David's $84,000 of lifetime tax savings doesn't come from one clever move. It comes from running the math once at age 64 instead of defaulting to the path of least resistance. The default plan isn't wrong because the individual decisions are wrong — taking CPP at 65 is fine in isolation, taking OAS at 65 is fine in isolation, leaving RRSPs alone is fine in isolation. The default plan is wrong because the three decisions interact, and the interaction compounds against you over a 25-year retirement.
The lever isn't a tax trick. The lever is the willingness to spend two hours with a CFP modeling the 25-year tax curve under both plans, comparing the deltas, and accepting that the higher-tax years 65-69 buy you lower-tax years 75-90. Most retirees never run that math. That's the $84,000.

Q:Should I take CPP at 65 or defer to 70 in 2026?
A:For a healthy 65-year-old with adequate non-CPP income, deferring CPP to age 70 is usually the right call. The CPP Act gives you a 0.7% monthly enhancement for every month you delay past 65, capped at 42% at age 70. On the 2026 maximum CPP of $1,507.65/month at 65, that's $2,141.86/month at 70 — an extra $7,610/year of fully-indexed, longevity-protected income for life. Break-even versus taking at 65 happens at age 81-82, well within median Canadian life expectancy (84.4 for men, 87.0 for women at age 65). The exceptions: terminal diagnosis, family history of lifespan under 80, or genuine cash-flow need at 65. For a single retiree with $750K in RRSPs and no defined-benefit pension, deferring CPP is almost always the right call — the larger CPP cheque at 70 reduces the pressure on RRSP withdrawals in your late 70s and 80s.
Q:How does the OAS deferral enhancement work in 2026?
A:The OAS Act allows you to defer Old Age Security from age 65 to a maximum of age 70 for a 0.6%/month enhancement, totalling 36% if deferred the full 5 years. On the 2026 maximum OAS of $742.31/month at age 65-74, the deferred amount at 70 is $1,009.54/month — an extra $3,207/year of indexed income for life. After age 75, the 10% top-up applies on top of the deferred amount. Unlike CPP, OAS is funded from general government revenue (not contributions), so the deferral decision is purely an actuarial bet on longevity. Break-even is age 82-83. The deferral is most valuable when other income sources (CPP, RRSP withdrawals) can cover the gap between 65 and 70, and when you're trying to avoid the OAS clawback (recovery tax of 15% on income above $95,323 in 2026).
Q:What is the RRSP meltdown strategy?
A:An RRSP meltdown is the deliberate, accelerated withdrawal of RRSP funds during low-income years — typically between retirement and the start of CPP/OAS, or between retirement and age 71 (the mandatory RRIF conversion deadline). The goal is to pull money out of the RRSP at low marginal tax rates rather than letting it compound into a large RRIF balance that triggers mandatory withdrawals at 5.28%+/year starting at age 71, often at high marginal rates and OAS-clawback-triggering levels. For a single retiree with $750,000 in RRSPs and no employment income from age 65, withdrawing $50,000/year for five years (ages 65-69) takes $250,000 out of the RRSP at a blended combined Ontario marginal rate of roughly 20-24% — far below the 30-40%+ rate the same dollars would face if withdrawn at 75 stacked on top of CPP, OAS, and RRIF minimums. The withdrawn funds can be contributed to TFSA (using cumulative room of $109,000 in 2026), invested in a non-registered account, or simply spent.
Q:How much does OAS clawback cost a retiree with $750,000 in RRSPs?
A:The OAS clawback (recovery tax under ITA s. 180.2) starts at $95,323 of net income in 2026 and claws back 15 cents of every additional dollar of income. OAS is fully clawed back at roughly $155,000 of income. For a single retiree who takes CPP and OAS at 65 and leaves the $750,000 RRSP to grow until the mandatory RRIF conversion at 71, here's the trajectory: at 71, the 5.28% RRIF minimum on a balance grown to ~$1,000,000 (assuming 5% nominal growth and no withdrawals from 65-70) is $52,800. Add indexed CPP (~$22,000) and OAS (~$10,900), and net income is ~$85,700 — under the clawback. But by age 78, the 6.36% RRIF minimum on a still-growing balance pushes income past $95,323, triggering ~$2,500/year of clawback. By age 85, the 8.51% minimum and 8.99% at 86 push the clawback to $5,000+/year. Over a 25-year retirement (65-90), the cumulative cost of OAS clawback in the default-plan scenario is roughly $45,000-$60,000. The RRSP meltdown strategy keeps the RRIF balance small enough at 71 that the minimums stay under the clawback threshold for the rest of life.
Q:What is the combined CPP and OAS amount at age 70 in 2026?
A:For a Canadian who qualified for the maximum CPP at age 65 ($1,507.65/month in 2026) and deferred to 70 (+42% under the CPP Act), the CPP cheque at 70 is $2,141.86/month or $25,702/year. The OAS deferred from 65 to 70 (+36% under the OAS Act) increases from $742.31/month to $1,009.54/month or $12,114/year. Combined, the deferred CPP+OAS at age 70 totals $3,151.40/month or $37,816/year, indexed for inflation each year thereafter. By comparison, taking both at 65 produces $2,250/month or $27,000/year — a difference of $10,816/year of fully indexed, longevity-protected income that lasts the rest of your life. After age 75, the OAS 10% top-up adds another ~$100/month, bringing the deferred combined total above $3,250/month at 75+.
Q:Should I convert my RRSP to a RRIF before age 71?
A:You don't have to convert your RRSP to a RRIF before age 71 to start withdrawing — you can take ad-hoc lump-sum withdrawals directly from the RRSP at any age. The conversion to RRIF is only mandatory by December 31 of the year you turn 71. For meltdown strategy purposes, ad-hoc RRSP withdrawals are usually preferable to early RRIF conversion: you control the timing and amount precisely, whereas a RRIF locks you into mandatory minimums. The downside of RRSP withdrawals: the financial institution applies withholding tax at source (10% on amounts up to $5,000, 20% on $5,001-$15,000, 30% on amounts over $15,000 in 2026). The withholding is a prepayment of your actual tax owing, reconciled on your T1 return — so if your actual marginal rate is 22%, you get a refund on the over-withheld portion. Some retirees prefer to convert a small portion of the RRSP to a RRIF at 65 (e.g. $50,000) to use the $2,000 pension income tax credit annually. The pension credit alone is worth $400/year ($2,000 × 20% federal credit) — modest but stackable across 6 years (65-70) before mandatory conversion.
Q:When does the RRSP meltdown strategy NOT work?
A:The RRSP meltdown is the wrong call in three specific situations. First, if you have a defined-benefit pension that already puts you above $80,000 of guaranteed income from age 65, your 'low-income window' between 65 and 70 isn't actually low — adding $50,000 of RRSP withdrawals on top pushes you into the 33-44% marginal bracket immediately, eliminating the arbitrage. Second, if you have terminal health or strong family history of life expectancy under 80, deferring CPP and OAS gives back the actuarial bet — you may not live to the break-even age of 82. Third, if you qualify for the Guaranteed Income Supplement (GIS) — applicable when income is below approximately $22,000 for a single person in 2026 — the meltdown can disqualify you from GIS for those years, costing more than the marginal-rate savings. The meltdown is most valuable for single retirees with $300K-$2M of RRSPs, no DB pension, no GIS exposure, and a normal life expectancy. That's a large slice of the Canadian retiree population, but not all of it.
Q:How much tax does the optimal CPP-OAS-RRSP sequence save versus the default plan?
A:For the scenario in this article — a single, healthy 65-year-old in Ontario with $750,000 in RRSPs, $80,000 in TFSA, no defined-benefit pension, full CPP eligibility, and median life expectancy to age 87 — the optimal sequence (defer CPP and OAS to 70, melt $50,000/year from RRSP 65-69) saves approximately $84,000 in lifetime tax versus the default (take CPP and OAS at 65, leave RRSP to grow, mandatory RRIF at 71). The savings come from three sources: (1) ~$30,000 from avoiding OAS clawback in years 78-90 by keeping RRIF balance smaller; (2) ~$25,000 from withdrawing RRSP at 20-24% marginal rates in years 65-69 instead of 30-40% rates in years 75-90; (3) ~$29,000 from the larger inflation-protected CPP+OAS cheque after 70 ($10,816/year × ~17 years of expected life past age 70, net of tax). The savings figure varies by longevity assumption — at age 80 the optimal sequence is roughly break-even; at age 87 it's $84,000 ahead; at age 92 it's $130,000+ ahead.
Question: Should I take CPP at 65 or defer to 70 in 2026?
Answer: For a healthy 65-year-old with adequate non-CPP income, deferring CPP to age 70 is usually the right call. The CPP Act gives you a 0.7% monthly enhancement for every month you delay past 65, capped at 42% at age 70. On the 2026 maximum CPP of $1,507.65/month at 65, that's $2,141.86/month at 70 — an extra $7,610/year of fully-indexed, longevity-protected income for life. Break-even versus taking at 65 happens at age 81-82, well within median Canadian life expectancy (84.4 for men, 87.0 for women at age 65). The exceptions: terminal diagnosis, family history of lifespan under 80, or genuine cash-flow need at 65. For a single retiree with $750K in RRSPs and no defined-benefit pension, deferring CPP is almost always the right call — the larger CPP cheque at 70 reduces the pressure on RRSP withdrawals in your late 70s and 80s.
Question: How does the OAS deferral enhancement work in 2026?
Answer: The OAS Act allows you to defer Old Age Security from age 65 to a maximum of age 70 for a 0.6%/month enhancement, totalling 36% if deferred the full 5 years. On the 2026 maximum OAS of $742.31/month at age 65-74, the deferred amount at 70 is $1,009.54/month — an extra $3,207/year of indexed income for life. After age 75, the 10% top-up applies on top of the deferred amount. Unlike CPP, OAS is funded from general government revenue (not contributions), so the deferral decision is purely an actuarial bet on longevity. Break-even is age 82-83. The deferral is most valuable when other income sources (CPP, RRSP withdrawals) can cover the gap between 65 and 70, and when you're trying to avoid the OAS clawback (recovery tax of 15% on income above $95,323 in 2026).
Question: What is the RRSP meltdown strategy?
Answer: An RRSP meltdown is the deliberate, accelerated withdrawal of RRSP funds during low-income years — typically between retirement and the start of CPP/OAS, or between retirement and age 71 (the mandatory RRIF conversion deadline). The goal is to pull money out of the RRSP at low marginal tax rates rather than letting it compound into a large RRIF balance that triggers mandatory withdrawals at 5.28%+/year starting at age 71, often at high marginal rates and OAS-clawback-triggering levels. For a single retiree with $750,000 in RRSPs and no employment income from age 65, withdrawing $50,000/year for five years (ages 65-69) takes $250,000 out of the RRSP at a blended combined Ontario marginal rate of roughly 20-24% — far below the 30-40%+ rate the same dollars would face if withdrawn at 75 stacked on top of CPP, OAS, and RRIF minimums. The withdrawn funds can be contributed to TFSA (using cumulative room of $109,000 in 2026), invested in a non-registered account, or simply spent.
Question: How much does OAS clawback cost a retiree with $750,000 in RRSPs?
Answer: The OAS clawback (recovery tax under ITA s. 180.2) starts at $95,323 of net income in 2026 and claws back 15 cents of every additional dollar of income. OAS is fully clawed back at roughly $155,000 of income. For a single retiree who takes CPP and OAS at 65 and leaves the $750,000 RRSP to grow until the mandatory RRIF conversion at 71, here's the trajectory: at 71, the 5.28% RRIF minimum on a balance grown to ~$1,000,000 (assuming 5% nominal growth and no withdrawals from 65-70) is $52,800. Add indexed CPP (~$22,000) and OAS (~$10,900), and net income is ~$85,700 — under the clawback. But by age 78, the 6.36% RRIF minimum on a still-growing balance pushes income past $95,323, triggering ~$2,500/year of clawback. By age 85, the 8.51% minimum and 8.99% at 86 push the clawback to $5,000+/year. Over a 25-year retirement (65-90), the cumulative cost of OAS clawback in the default-plan scenario is roughly $45,000-$60,000. The RRSP meltdown strategy keeps the RRIF balance small enough at 71 that the minimums stay under the clawback threshold for the rest of life.
Question: What is the combined CPP and OAS amount at age 70 in 2026?
Answer: For a Canadian who qualified for the maximum CPP at age 65 ($1,507.65/month in 2026) and deferred to 70 (+42% under the CPP Act), the CPP cheque at 70 is $2,141.86/month or $25,702/year. The OAS deferred from 65 to 70 (+36% under the OAS Act) increases from $742.31/month to $1,009.54/month or $12,114/year. Combined, the deferred CPP+OAS at age 70 totals $3,151.40/month or $37,816/year, indexed for inflation each year thereafter. By comparison, taking both at 65 produces $2,250/month or $27,000/year — a difference of $10,816/year of fully indexed, longevity-protected income that lasts the rest of your life. After age 75, the OAS 10% top-up adds another ~$100/month, bringing the deferred combined total above $3,250/month at 75+.
Question: Should I convert my RRSP to a RRIF before age 71?
Answer: You don't have to convert your RRSP to a RRIF before age 71 to start withdrawing — you can take ad-hoc lump-sum withdrawals directly from the RRSP at any age. The conversion to RRIF is only mandatory by December 31 of the year you turn 71. For meltdown strategy purposes, ad-hoc RRSP withdrawals are usually preferable to early RRIF conversion: you control the timing and amount precisely, whereas a RRIF locks you into mandatory minimums. The downside of RRSP withdrawals: the financial institution applies withholding tax at source (10% on amounts up to $5,000, 20% on $5,001-$15,000, 30% on amounts over $15,000 in 2026). The withholding is a prepayment of your actual tax owing, reconciled on your T1 return — so if your actual marginal rate is 22%, you get a refund on the over-withheld portion. Some retirees prefer to convert a small portion of the RRSP to a RRIF at 65 (e.g. $50,000) to use the $2,000 pension income tax credit annually. The pension credit alone is worth $400/year ($2,000 × 20% federal credit) — modest but stackable across 6 years (65-70) before mandatory conversion.
Question: When does the RRSP meltdown strategy NOT work?
Answer: The RRSP meltdown is the wrong call in three specific situations. First, if you have a defined-benefit pension that already puts you above $80,000 of guaranteed income from age 65, your 'low-income window' between 65 and 70 isn't actually low — adding $50,000 of RRSP withdrawals on top pushes you into the 33-44% marginal bracket immediately, eliminating the arbitrage. Second, if you have terminal health or strong family history of life expectancy under 80, deferring CPP and OAS gives back the actuarial bet — you may not live to the break-even age of 82. Third, if you qualify for the Guaranteed Income Supplement (GIS) — applicable when income is below approximately $22,000 for a single person in 2026 — the meltdown can disqualify you from GIS for those years, costing more than the marginal-rate savings. The meltdown is most valuable for single retirees with $300K-$2M of RRSPs, no DB pension, no GIS exposure, and a normal life expectancy. That's a large slice of the Canadian retiree population, but not all of it.
Question: How much tax does the optimal CPP-OAS-RRSP sequence save versus the default plan?
Answer: For the scenario in this article — a single, healthy 65-year-old in Ontario with $750,000 in RRSPs, $80,000 in TFSA, no defined-benefit pension, full CPP eligibility, and median life expectancy to age 87 — the optimal sequence (defer CPP and OAS to 70, melt $50,000/year from RRSP 65-69) saves approximately $84,000 in lifetime tax versus the default (take CPP and OAS at 65, leave RRSP to grow, mandatory RRIF at 71). The savings come from three sources: (1) ~$30,000 from avoiding OAS clawback in years 78-90 by keeping RRIF balance smaller; (2) ~$25,000 from withdrawing RRSP at 20-24% marginal rates in years 65-69 instead of 30-40% rates in years 75-90; (3) ~$29,000 from the larger inflation-protected CPP+OAS cheque after 70 ($10,816/year × ~17 years of expected life past age 70, net of tax). The savings figure varies by longevity assumption — at age 80 the optimal sequence is roughly break-even; at age 87 it's $84,000 ahead; at age 92 it's $130,000+ ahead.
