BMO InvestorLine Drops All Trading Fees: What It Means for Your Brokerage Choice
On September 14, 2026, a new cardholder at BMO InvestorLine placed an order for 11 shares of Canadian National Railway. The trade cost $0.00 in commissions. That same trade cost $9.95 the day before.
The move is BMO's response to five years of margin compression in Canadian online brokerages, where Wealthsimple and Questrade have conditioned an entire cohort of millennial and Gen Z investors to expect free trading. BMO becomes the first among Canada's Big Five banks to eliminate trading commissions, and the shift is permanent. The old $9.95 model is done.
What "Free" Actually Covers
The zero-commission applies to all online trades of Canadian and U.S. equities and ETFs. Phone-assisted trades still carry fees. So do over-the-counter securities and fractional shares. The quarterly account maintenance fee (typically $25 if your balance falls below $15,000) is also eliminated under the new structure.
Currency conversion is where the bank earns. When you buy a U.S. stock with Canadian dollars, BMO applies a foreign exchange spread of roughly 1.5 to 2 percent above the mid-market rate. On a $5,000 USD purchase, that spread costs you $75 to $100. BMO charges you nothing for the trade itself, but it takes $75 to $100 on the currency conversion.
Why the Big Five Held Out
Canadian banks resisted zero-commission longer than their U.S. peers because the market is more concentrated and the revenue model was more stable. In the U.S., Charles Schwab eliminated commissions in October 2019, forcing TD Ameritrade, E*TRADE, and Fidelity to follow within 72 hours. Canada's Big Five control 85 percent of retail brokerage assets, so there was less immediate competitive pressure.
That changed when Wealthsimple's user base passed 3 million in early 2025, pulling younger clients away from traditional bank platforms. The Investment Industry Regulatory Organization of Canada (now part of CIRO) reported that DIY investing accounts grew 34 percent from 2021 to 2025, with the steepest growth in the under-35 demographic. BMO is pursuing younger customers, betting they will stay as their account balances grow.
What You're Trading For
The practical trade-off is service depth. BMO InvestorLine Self-Directed accounts come with no dedicated advisor, slower phone support during volatility, and a platform that historically lags Questrade's desktop interface in speed. The bank is betting that institutional trust, a Tier 1 balance sheet, CDIC protection on cash balances, integration with your mortgage and credit card, outweighs those gaps.
For investors holding $250,000 or more, BMO offers a "Preferred" tier with live advisor access and estate-planning support, but those services carry separate fees. The free platform is designed as a funnel: bring clients in at zero cost, upsell them into AdviceDirect or proprietary BMO mutual funds as their portfolios grow.
The Hidden Costs That Remain
Management expense ratios on BMO's own ETF products range from 0.09 percent (BMO Aggregate Bond Index) to 0.74 percent (BMO Global Equity Fund). A $50,000 portfolio in the higher-MER fund pays $370 annually in embedded fees, invisible to most investors because they're deducted directly from fund returns. Commission-free doesn't mean cost-free.
The other structural cost is behavioural. Removing the $9.95 friction eliminates a psychological brake on overtrading. In the first six months after Robinhood launched commission-free trading in the U.S., average trade frequency among retail investors jumped 40 percent, according to a 2020 SEC staff report. More trades don't improve returns for most people. They erode them.
If you're an infrequent investor making four trades a year, the savings are $40. If you trade weekly, they're $500. If you're tempted to day-trade because the cost is zero, you've misunderstood what "free" means. The platform is free. Overconfidence is expensive.
