Beware: Famous money gurus’ advice could wreck Canadians’ finances — why some multimillionaires get it wrong (and what to do instead)

Other high-profile advice can be just as blunt. Kevin O'Leary (2) has suggested that people earning $70,000 should avoid buying a home. In Canada, real estate markets vary (3) between cities like Toronto, Calgary and Halifax, and that kind of blanket advice can miss the mark entirely.

Meanwhile, Dave Ramsey’s suggestion (4) that retirees can withdraw 8% annually from their savings has been widely debated. Many financial planners warn that such a rate could quickly deplete retirement funds — especially in Canada, where a longer life expectancy (5) increases the risk of outliving savings.

The core issue is context. Much of this advice assumes what worked for wealthy individuals will work for everyone — even though most households face very different financial realities, particularly in a high-cost country like Canada.

Social media is amplifying bad advice

The rise of financial influencers, or “finfluencers (6),” has made the problem worse.

Social media has become a major source of money advice (7) for younger Canadians. Platforms such as TikTok, Instagram and YouTube are now filled with content on budgeting, investing and side hustles, often presented in quick, digestible clips. That sounds promising, right?

However, this advice comes with risk. Research highlighted by the CFA Institute (8) shows that while younger generations increasingly rely on social media for financial education, the quality of advice can vary widely.

Part of the issue is that anyone can present themselves as an expert. Unlike licensed financial planners, influencers aren’t required to meet professional standards (9), yet their content can still shape real financial decisions.

That creates an environment where bad advice spreads quickly — and can be costly to follow.

Not all billionaire advice is wrong

Still, not all guidance from wealthy investors should be dismissed. In fact, some of the most reliable advice is also the simplest.

Both Mark Cuban and Warren Buffett emphasize one key principle (10): avoid high-interest debt.

Paying off debt delivers a return equal to your interest rate. For Canadians carrying credit card balances — where interest rates often exceed 20% (11) — eliminating that debt can provide a guaranteed return that’s hard to beat in the market.

Buffett also consistently advocates for low-cost index funds and long-term investing. This approach aligns well with Canadian options (12) like ETFs tracking the S&P/TSX Composite or global markets through registered accounts like TFSAs and RRSPs.

These notions are widely supported, and notably far less extreme than many viral money tips.

What financial advisors actually say

Professional financial planners tend to agree on a more grounded approach.

Across the board, financial experts emphasize the same fundamentals:

• Pay down high-interest debt: Eliminating debt first prevents interest from compounding against you. This is especially important in Canada, where household debt levels remain among the highest in the G7 (13).
• Build a budget and emergency fund: With rising living costs, having a financial buffer is critical. An emergency fund (14) can help Canadians weather job loss, rate hikes or unexpected expenses without relying on credit.
• Invest consistently over time: Rather than trying to time the market, steady contributions — particularly through tax-advantaged accounts like TFSAs and RRSPs (15) — allow Canadians to benefit from long-term growth.
• Diversify and rebalance portfolios: Spreading investments across sectors and geographies — and periodically rebalancing — helps manage risk, especially in a smaller market like Canada that is heavily weighted toward financials and energy.

Advisors also stress focusing on “needle movers” — major expenses like housing, transportation and income — rather than small lifestyle cuts like skipping coffee.

In other words, the most effective strategies aren’t flashy or extreme. They’re consistent and personalized.

How to protect yourself

With so much conflicting advice online, the key is learning how to filter what you hear.

Start by questioning one-size-fits-all rules. Personal finance depends on your income, location and goals, not someone else’s success story.
