Why the Active vs. Passive Debate Misses the Point Entirely
The moment you decide which index to track, S&P 500, Nasdaq 100, or S&P/TSX Composite, you've made an active choice. There is no neutral investment. The portfolio you're calling "passive" already carries sector bets, concentration risk, and a particular view on how value gets distributed across the market.
The debate between active and passive has calcified into tribal loyalty, where investors feel pressured to pick a side and defend it. Meanwhile, the institutions managing the largest pools of capital in Canada, pension funds like CPPIB, use both. They run low-cost index exposure as their core and layer active mandates on top where information inefficiencies create opportunity.
Why the Binary Breaks Down
Passive investing now controls over 50% of U.S. equity fund assets, though Canada lags significantly at 22.6% as of year-end 2025. That's a tectonic shift, but it hasn't eliminated the need for price discovery. Active managers still set the prices that passive funds then track. The more capital that flows into indexing, the fewer people are doing the fundamental research required to value companies accurately. That creates opportunity for the active managers who remain, particularly in corners of the market where information doesn't move instantly, small caps, emerging markets, private credit.
At the same time, many "passive" products have become active without admitting it. Smart Beta ETFs use screens to overweight quality, momentum, or value factors. That's stock selection. It's just rules-based instead of discretionary. Many products marketed as passive are really selling a marketing label built on rule-based stock selection.
The Core-Satellite Model
A more useful framework: build a passive core that provides low-cost exposure to broad beta, then use active satellites to chase alpha in specific pockets where managers have an edge. For a Canadian investor, that might mean an S&P/TSX 60 ETF charging 0.05% as the foundation, with an active small-cap manager or a sector-specific fund in the satellite positions.
The advantage is cost control. The average passive ETF in Canada runs 0.05% to 0.20% in fees. Active mutual funds still hover between 1.5% and 2.2%. A portfolio that is 70% passive and 30% active lands at a blended fee well below what an all-active approach would cost, while still allowing room for tactical bets.
Where Active Still Outperforms
Fixed income is the clearest case. Active bond managers tend to beat their benchmarks more consistently than equity managers, largely because bond indices are "bums indices", they overweight the most indebted issuers. A passive corporate bond ETF gives you the heaviest exposure to the companies that have borrowed the most, which is not always where you want to be. Active managers can avoid that.
Active management also holds an advantage in volatile or bear markets. Passive funds must stay fully invested. Active managers have the mandate to move to cash, hedge, or trim positions when conditions deteriorate. That flexibility has value, even if it doesn't show up in every trailing 10-year return.
The Canadian Concentration Problem
The S&P/TSX Composite has a structural problem: the top 10 holdings account for roughly 35-40% of the index's total value, and those names are heavily tilted toward Financials and Energy. A purely passive approach to Canadian equity means you're taking a massive sector bet whether you intended to or not. An active manager, or even just a strategic tilt toward global diversification, can reduce that imbalance.
The Real Question
The debate shouldn't be "active or passive." It should be "where does active add value, and where does it just add cost?" That's a question with different answers depending on the asset class, the investor's time horizon, and the current state of market efficiency.
The greatest risk isn't picking the wrong camp. It's paying active fees for a manager who simply mimics the index, what the industry calls closet indexing. Active share measures how much a fund's holdings differ from its benchmark. If you're paying 2% for a portfolio with 60% active share, you're funding a high-cost index tracker.
