Think CPP and OAS will be enough? Most Canadians find out too late — here’s how to avoid the retirement shock

Imagine you’re 64, a year away from retirement, and finally sitting down to run those post-employment numbers. You punch in your expected Canada Pension Plan (CPP) and Old Age Security (OAS) payments and feel a momentary wave of relief — until you compare those benefits to your actual monthly expenses. The gap is bigger than you expected. Suddenly, that all too familiar assumption that CPP and OAS will be enough just doesn’t hold up.

This is a common wake-up call for Canadians approaching retirement. Government benefits provide a foundation, but they rarely replace enough income to maintain the lifestyle most people want or expect in retirement. This, despite how out-of-favour the Registered Retirement Savings Plan (RRSP) has become among working Canadians. For some, the RRSP is either outdated or too complicated or only useful for high-income earners, but the opposite is true. A well-planned RRSP can be the tool that fills the gap between what government programs provide and what you’ll actually need to live securely and comfortably in retirement.

Here's how an RRSP continues to be one of the most effective ways to save for a quality retirement.

Calculate the retirement income you’ll actually need

Start by estimating your monthly expenses in retirement — housing, food, utilities, transportation, medical costs and discretionary spending. Then compare this total to your projected CPP and OAS income. The difference is the amount your personal savings, including your RRSP, must cover.

Reduce taxes today with RRSP contributions

RRSP contributions lower your taxable income, which can leave more money in your pocket each year. Use available contribution room strategically — especially in high-earning years — to maximize the tax benefit.

Invest for long-term growth

Keep your RRSP invested. The tax-deferred structure allows your investments to compound faster than they would in a taxable account. Whether you prefer low-cost index funds, balanced portfolios or more active strategies, consistency is key.

Plan your withdrawals wisely

When you convert your RRSP to a RRIF, you control how and when to draw income. Coordinating RRIF withdrawals with CPP, OAS and other savings can help you reduce taxes and stretch your income through retirement.

Ignore myths that discourage smart planning

RRSPs aren’t just for high-income earners. They aren’t outdated. And they aren’t inferior to TFSAs — they simply serve a different purpose. When used properly, the RRSP remains one of the strongest tools Canadians have for funding retirement.

Using these steps, you can build a retirement plan that doesn’t rely solely on government benefits — and offers the financial security and lifestyle you’re aiming for.

Bottom line

CPP and OAS alone won’t fund the retirement most Canadians expect — but an RRSP can. By calculating what you’ll truly need, contributing consistently, investing for growth and planning withdrawals strategically, you can turn your RRSP into a reliable source of income that fills the gap and protects your standard of living for decades to come.
