Retirement Planning: CPP, OAS, RRSP, and You

Why Retirement Planning Cannot Wait

The single most valuable resource in retirement planning is time. A 25-year-old who invests $300 per month until 65 accumulates approximately $790,000 (at 7% average return). A 35-year-old investing the same amount has only $365,000 at 65. Waiting 10 years cost $425,000 — more than the 35-year-old’s entire portfolio.

Yet most young Canadians put off retirement planning because it feels impossibly distant and the present feels more pressing. The irony is that the years when retirement feels most irrelevant are precisely the years when action has the greatest impact.

This lesson gives you a concrete understanding of what retirement costs, what Canada’s public pension system provides, and what you need to fund yourself.

Canada’s Three-Pillar Retirement System

Canada’s retirement income system has three pillars:

1. Government pensions (CPP + OAS): Provide a baseline income
2. Employer pensions and registered plans (RRSP): Build additional retirement savings
3. Personal savings and investments (TFSA, non-registered): Fill the gap

No single pillar is designed to fund your entire retirement. Understanding how they work together is essential.

Pillar 1: Canada Pension Plan (CPP)

CPP is a mandatory contributory pension. If you work in Canada (outside Quebec, which has the QPP), you and your employer each contribute a percentage of your earnings to CPP. Self-employed individuals pay both portions.

How CPP Benefits Are Calculated

Your CPP retirement pension is based on your average earnings over your contributing years (roughly age 18 to 65). The calculation drops your lowest-earning years (up to 8 years or approximately 17% of contributing years) and uses a formula to determine your benefit.

CPP Amounts

Maximum CPP retirement pension at age 65: approximately $1,365 per month (2024 figures, indexed to inflation annually).

Average CPP retirement pension: approximately $815 per month. Most Canadians do not receive the maximum because they did not consistently earn at or above the maximum pensionable earnings ($68,500 in 2024) throughout their career.

When to Start CPP

You can start CPP as early as age 60 or as late as age 70:

Delayed CPP is usually better if you are healthy and have other income sources between 60-70. The 42% increase for waiting to 70 is essentially a guaranteed 8.4% annual return — far better than most safe investments. However, if you have health concerns or need the income immediately, starting earlier makes sense.

CPP Enhancement

Since 2019, enhanced CPP contributions mean that today’s younger workers will receive higher benefits than current retirees. The enhancement increases the maximum benefit by up to one-third for those who contribute throughout the enhancement period.

Pillar 2: Old Age Security (OAS)

OAS is a monthly pension available to most Canadians aged 65 or older. Unlike CPP, OAS is not based on employment contributions — it is funded by general tax revenue.

OAS Eligibility and Amounts

Full OAS: Available if you have lived in Canada for at least 40 years after turning 18. The maximum monthly payment is approximately $714 (2024, indexed quarterly to CPI).

Partial OAS: If you have lived in Canada for 10 to 40 years, you receive 1/40th of the full amount per year of residence.

Deferral: Like CPP, you can defer OAS to age 70 for a 36% increase (0.6% per month).

The OAS Clawback

OAS includes an income-tested recovery tax (commonly called the “clawback”). If your net income exceeds approximately $90,000 (2024 threshold, indexed), you repay 15 cents of OAS for every dollar above the threshold. At approximately $148,000 in net income, OAS is fully clawed back.

Critical planning point: RRSP/RRIF withdrawals count as income and can trigger the OAS clawback. TFSA withdrawals do NOT count as income. This is a major advantage of the TFSA in retirement — it provides income without triggering clawbacks. Balancing RRSP and TFSA usage in retirement is one of the most valuable retirement planning strategies.

Pillar 2.5: Guaranteed Income Supplement (GIS)

GIS provides additional monthly income to low-income OAS recipients. If your annual income (excluding OAS) is below approximately $21,000 for a single senior, you receive GIS payments of up to approximately $1,065 per month.

GIS is a critical safety net for Canada’s most vulnerable seniors, but it is income-tested aggressively. Every dollar of non-OAS income reduces GIS by 50 to 75 cents. RRIF withdrawals count as income and reduce GIS. TFSA withdrawals do not.

For low-income retirees, the combination of OAS + GIS provides approximately $1,779 per month ($21,348 per year), which is above Statistics Canada’s low-income threshold but leaves little margin.

Pillar 3: Your Personal Savings

Here is the uncomfortable math. The maximum CPP + OAS for a single person is approximately $2,079 per month ($24,948 per year). The average is closer to $1,529 per month ($18,348 per year).

If you want a comfortable retirement — defined by most financial planners as replacing 70% of your pre-retirement income — you need substantially more.

The Retirement Gap Calculation

Example: Current income of $60,000

You need $23,652 per year from your own savings. Using the 4% rule (a common retirement planning guideline that suggests withdrawing 4% of your portfolio per year provides approximately 30 years of income), you need a portfolio of approximately $591,300 at retirement.

How to Build $591,300

Starting at different ages, here is the monthly investment needed (assuming 7% average return):

At 25, you need $226 per month — roughly $52 per week. At 40, you need over three times that. Every year of delay increases the required monthly contribution significantly.

RRSP to RRIF Transition

By December 31 of the year you turn 71, your RRSP must be converted to a Registered Retirement Income Fund (RRIF), an annuity, or collapsed (with all funds taxed as income).

Most Canadians choose the RRIF. Your investments stay in the same portfolio, but you must withdraw a minimum percentage each year based on your age:

These mandatory withdrawals are taxed as income and can trigger OAS clawbacks. This is why many financial planners recommend drawing down RRSP/RRIF strategically in your 60s — before mandatory minimums kick in — to smooth out your taxable income and minimize clawbacks.

Pension Income Splitting

Canadian tax law allows couples to split eligible pension income, which can produce significant tax savings. If one spouse has a large pension or RRIF income and the other has little, splitting allocates up to 50% of eligible pension income to the lower-income spouse, reducing the couple’s overall tax burden.

Eligible income for splitting:

• RRIF payments (at any age if from a deceased spouse’s plan; otherwise at age 65+)
• Life annuity payments from a registered pension plan (at any age)
• Other pension payments (at age 65+)

Not eligible: CPP (which has its own sharing provisions), OAS, GIS

Pension splitting can save couples thousands per year in taxes and help avoid or reduce OAS clawbacks. For broader context on retirement planning approaches, see the retirement planning guide for different contexts.

Creating Your Retirement Plan

Step 1: Estimate Your Expenses

What will retirement cost? Common adjustments from working-life expenses:

• Lower: No commuting costs, no work clothes, no CPP/EI deductions, mortgage may be paid off
• Higher: More healthcare costs, more travel (early retirement), potentially more leisure spending
• Roughly the same: Food, housing (if renting), utilities, insurance

A common rule: plan for 70% of pre-retirement gross income as a starting point, then adjust based on your specific plans.

Step 2: Calculate Your Government Benefits

Use the Service Canada CPP estimator (available through My Service Canada Account) to project your actual CPP benefit based on your earnings history.

Step 3: Calculate Your Gap

Subtract expected CPP + OAS from your target income. The difference is what your personal savings must provide.

Step 4: Determine Required Savings

Apply the 4% rule: multiply your annual gap by 25 to get your target portfolio.

Step 5: Set Your Contribution Plan

Based on your current age and target portfolio, calculate the monthly contribution needed. Automate this contribution to your TFSA and RRSP, invested in a globally diversified ETF portfolio.

Step 6: Review Annually

Revisit your plan each year. Update assumptions for actual investment returns, salary changes, and evolving retirement goals.

Key Takeaways

• Canada’s retirement system has three pillars: government pensions (CPP/OAS), employer/registered plans (RRSP), and personal savings (TFSA).
• Maximum CPP + OAS provides approximately $25,000 per year — most Canadians need $15,000 to $25,000 per year more from personal savings.
• Delaying CPP to age 70 increases payments by 42% — a guaranteed return far exceeding most safe investments.
• OAS clawbacks make TFSA withdrawals (which do not count as income) especially valuable in retirement versus RRSP/RRIF withdrawals.
• The 4% rule suggests a portfolio of 25 times your annual retirement income gap.
• Starting at 25, you need approximately $226 per month to build a $591,000 retirement portfolio; waiting until 40 requires $745 per month.
• RRSP to RRIF conversion at age 71 triggers mandatory withdrawals — strategic drawdown in your 60s can minimize taxes and clawbacks.

In the final lesson, you will learn how Canadian taxes work — CRA basics, income tax brackets, RRSP deduction strategies, capital gains treatment, and why the TFSA is the ultimate tax shelter.
