Mutual Funds vs. ETFs in Canada: Why Dimensional Uses Mutual Funds

In this episode of Rational Reminder, Ben Felix, Cameron Passmore, and Ben Wilson return with a classic AMA format—answering listener questions that dig deep into the behavioral and evidence-based foundations of sensible investing. From lump-sum investing to the psychology of advice, the trio blend data, humor, and clear thinking to demystify complex financial ideas. They discuss the behavioral logic behind dollar-cost averaging, why mutual funds might actually be more tax-efficient than ETFs in Canada, and whether technology could ever truly replace human financial advisors. Plus, they share their biggest investing mistakes (yes, Bitcoin makes an appearance), dissect the rise of "buffered" ETFs, and explain why chasing complexity usually costs investors more than it helps.
