More Canadians are becoming millionaires — but many are making mistakes that could cost them dearly. Here's how to stop the bleed

Much of that growth is tied to real estate. As home values rose in major cities and even mid-sized markets over the past decade, many middle-class homeowners became millionaires without making any conscious investment decisions. They simply stayed in place.

But here’s the thing: A seven-figure net worth doesn’t automatically mean you’re financially set for retirement. And many of these new millionaires don’t feel wealthy — because in practical terms, they may not be. Here’s why.

The hidden millionaire phenomenon

Most Canadians agree they need around $1.7 million for a comfortable retirement, according to a 2026 BMO Retirement Survey (2). But if your $1 million net worth includes a $900,000 home and only $100,000 in cash savings, you’re likely well short of what you’ll actually need to fund a 30-year retirement — even before factoring in inflation.

Financial researchers have started using the term “hidden millionaire” to describe people who built most of their wealth through home equity and retirement savings, but don’t think of themselves as investors or high-net-worth individuals. They didn’t pick stocks or build a portfolio. They paid their mortgage, contributed to their Registered Retirement Savings Plan (RRSP) and watched their home value appreciate. Now they’re sitting on a million dollars — and have no idea what to do with it.

Why hidden millionaires may be putting themselves at risk

If you’ve crossed the seven-figure threshold without consciously managing your wealth, there’s a real chance your money isn’t working as hard as it could, or is slowly eroding. Here are some considerations:

Lifestyle creep is a slow leak. The biggest threat to any millionaire’s wealth isn’t a market crash — it’s gradually spending more as your income rises. Retirement savings that look impressive today can shrink faster than expected if your spending isn’t kept in check. The simple principle of living below your means doesn’t disappear once you hit a million dollars: It becomes more important.

Concentrated wealth is a vulnerability. Many hidden millionaires have most of their net worth tied up in one or two places — typically a home, and a single employer’s pension or stock plan. That concentration creates risk. If property values in your area decline, or if a company’s shares drop sharply, a large portion of your wealth can evaporate. A 2025 study in the Journal of Asset Management found that broad diversification across asset classes reduces risk and improves returns compared to putting everything all in one place, even through major market shocks (3).

Cash sitting idle is money left behind. A common mistake when rolling over or transferring registered accounts is failing to reinvest funds. Money that sits as cash inside a Tax-Free Savings Account (TFSA) or Registered Retirement Income Fund (RRIF) isn’t growing. A 2025 TD Bank survey states that about 4 in 10 Gen Z and Millennial Canadians keep most of their TFSA balances as cash — and are missing out on the account’s primary advantage: Tax-free compounding (4).

How hidden millionaires can make their wealth last

The good news is that none of these scenarios require anyone to start over from scratch. A few intentional shifts in how you manage your money can make a significant difference over the long run.

Get professional guidance. One of the most consistent habits among wealthy Canadians is working with a qualified professional. However, many hidden millionaires who didn’t consciously build their wealth through investments don’t think to seek that kind of help. A fee-only financial advisor or certified financial planner can help you assess your readiness for retirement, identify gaps and build a strategy that fits your specific situation. The Financial Planning Standards Council (FP Canada) keeps a national directory of certified planners (5).
