Canada's securities regulators just changed the rules for millions of stock trades — here's why it matters

The amendments come into force on November 2, 2026, provided all necessary ministerial approvals are obtained.

For most retail investors, this change won't show up as a line item in their brokerage app. But it matters — particularly for active traders, institutional investors and anyone holding dual-listed Canadian stocks.

What are active trading fees — and who actually pays them?

When a trade executes on a Canadian stock exchange, the marketplace — the exchange itself or an alternative trading system — charges a fee to the broker routing the order. These are called active trading fees, sometimes called "taker" fees, and they're part of the market infrastructure most retail investors never think about.

Brokerages typically absorb or pass on these fees depending on their pricing model. Zero-commission brokerages often make up the difference through other mechanisms, while full-service or active-trading platforms may pass transaction costs on directly to the investor. Either way, high exchange fees can influence the spread between buy and sell prices that all investors experience.

Before this regulator-initiated change, the fee structure differed depending on whether a stock was also listed in America. The CSA's amendment brings all securities priced at $1.00 or more under a single unified active trading fee cap of $0.0017 per share.

Why dual-listed stocks are at the centre of this change

This amendment will directly impact trading costs for investors who held shares in major Canadian companies like Shopify (TSX:SHOP), Barrick Gold (TSX:ABX) or Royal Bank of Canada (TSX:RY), all of which trade on both the Toronto Stock Exchange (TSX) and a U.S. exchange.

In a related move, the Canadian Investment Regulatory Organization (CIRO) published amendments to align Canadian trading increments for certain U.S. inter-listed securities with the equivalent minimum pricing increment used in the U.S. (2).

Together, these small but critical updates help create greater cross-border consistency — and potentially reduce the arbitrage opportunities that arise from fee and increment mismatches.

For Canadian investors who trade major Canadian firms or companies cross-listed on U.S. exchanges, this more consistent pricing structure means tighter spreads and more predictable execution costs.

What changes — and what doesn't — for retail investors

If you invest through a registered discount brokerage or a robo-advisor, the effect of this fee change is likely to be modest and indirect. The $0.0017 cap is charged at the marketplace level, not applied directly to your account like a commission.

That doesn't mean you won't benefit eventually. Lower infrastructure costs across the market tend to flow through over time — in tighter bid-ask spreads, lower per-trade costs for active traders and potentially reduced pricing pressure on discount platforms competing on commission-free structures.

The direct beneficiaries of these updates are active investors trading high volumes of dual-listed securities and institutional traders executing thousands of trades. Even a fraction-of-a-cent reduction per share can be meaningful at scale.

The CSA has stated it will monitor the impact of the fee cap change over time and assess whether further adjustments are required. Any future changes will be subject to public consultation.

Why regulators are tightening the screws on market fees

Canada's capital markets have undergone significant structural changes over the past decade, with multiple alternative trading systems competing alongside traditional exchanges for order flow. That competition has generally been good for investors — but it has also created a fragmented fee environment with varying caps across different security types.

The CSA received 10 responses during the public comment period following its January 23, 2025 request for comment. The final rule reflects consideration of that feedback.

The move to harmonize fee caps aligns with a broader global trend toward market structure reform — one that regulators in the U.S. and Europe have also been navigating. For Canada, the change reinforces that trading infrastructure costs are a legitimate investor-protection concern, not just a technical matter for exchanges and brokerages.

The November 2, 2026, implementation date gives brokerages, exchanges and alternative trading systems time to adjust their systems ahead of the change.

What should investors do?

To confirm you are getting the benefits of the trading fee cap, you need to do the following:

Check the fine print. Check whether your brokerage discloses how active trading fees affect your transaction costs — look for "execution fees" or "marketplace fees" in its fee schedule.

Review dual-listed holding. If you frequently trade dual-listed Canadian stocks, ask your brokerage whether the November 2026 rule change will affect your per-trade pricing.
