Best Day Trading Platforms in Canada (October 2026): 9 Brokers Ranked by Commissions, Currency Fees and Margin Rates

How we ranked them

Fees were checked on October 9, 2026, using each broker's own pricing page where we could reach it. Fees change, so confirm before you open an account.

We ranked on four things, in order of how much they cost a busy trader:

1. Currency conversion. Charged every time you swap Canadian and US dollars.
2. Commissions. Charged per trade or per share.
3. Margin interest. Charged if you borrow to trade.
4. Tools. Speed, charts, Level 2 quotes and order types.

A warning before the ranking. The research is clear that most day traders lose money. Low fees slow the losses. They don't change the odds.

The comparison

Sources: broker pricing pages, October 9, 2026. Exchange and regulatory fees can apply on top.

1. Interactive Brokers: lowest total cost

IBKR is the only broker here that charges a commission on every trade and still comes out cheapest for many active traders. The reason is everything else.

• Commissions: C$0.01 per share with a C$1 minimum on Canadian stocks, capped at 0.5% of the trade. About US$0.005 per share with a US$1 minimum on US stocks. High-volume traders can pick tiered pricing that starts lower.
• Currency conversion: about 0.002% of the amount, with a minimum near US$2. On US$10,000 that's about US$2. At a typical broker it's about US$150.
• Margin: rates are set at a benchmark plus a small markup and are the lowest of any broker on this list.
• Tools: Trader Workstation is built for professionals, with direct routing and every order type.

The downside is complexity. The platform takes time to learn. See how to open an Interactive Brokers account in Canada.

Best for: anyone trading US stocks often, using margin, or trading size.

2. Questrade: best $0 platform

Questrade charges $0 on Canadian and US stocks and ETFs. Its Edge desktop platform has proper charting, hotkeys and advanced orders, which most free apps lack.

The cost to watch is currency conversion at about 1.5%. Questrade lets you hold US dollars in both registered and non-registered accounts, so you can convert once and keep trading. It also supports Norbert's Gambit for cheap conversion.

Best for: active traders who want free trades and a desktop platform.

3. Webull Canada: best free mobile tools

Webull charges $0 on Canadian and US stocks and gives new users free Nasdaq Level 2 quotes for a trial period. Its charts are among the best on a phone.

Best for: chart-focused traders who work from mobile.

4. National Bank Direct Brokerage: $0 at a bank

NBDB has charged $0 on all online stock and ETF trades since 2021. Its posted margin rates are 6.25% in Canadian dollars and 8.75% in US dollars.

Two costs to know: currency conversion is about 1.7% on amounts under US$25,000, and there's a $100 annual fee unless you hold $20,000, are 30 or younger, or meet another exemption.

Best for: traders who want everything at one bank.

5. BMO InvestorLine: $0 at a Big Five bank

BMO moved to $0 stock and ETF trades on September 14, 2026, the first of the five big banks to do it. See what changed at BMO.

Best for: existing BMO customers.

6. Wealthsimple: lowest posted margin rates

Wealthsimple charges $0 commissions and publishes its margin rates. As of September 18, 2026:

Currency conversion is 1.5% in a Canadian-dollar account. A US-dollar account costs $10 a month on Core and is included on higher tiers, with conversion fees that fall from 1.5% to 0% as the amount rises.

The catch is tools. It has no Level 2 data or direct routing, so it suits swing traders more than true day traders.

Best for: borrowing cheaply for longer holds.

7 to 9. Qtrade, Moomoo and TD

• Qtrade went to $0 on stocks and ETFs on October 28, 2025. Strong research, lighter trading tools.
• Moomoo Canada charges per share on both Canadian and US stocks, with a US$1.99 minimum on US trades. You're paying for its tools.
• TD Direct Investing charges $9.99, or $7.00 if you make 150 or more trades a quarter. Its TD Active Trader platform is powerful, but the commissions are hard to justify now that rivals are free.

What it really costs: two examples

Example 1: Canadian stocks. You make 20 round trips a month (40 trades) of 200 shares of a $30 stock.

For Canadian stocks alone, a $0 broker wins.

Example 2: US stocks, converting each time. You buy US$5,000 of a US stock with Canadian dollars and sell it the same day, converting back.

Do that ten times a month and the "free" broker costs about US$1,500.

The fix is simple: hold US dollars. Convert once, then trade US stocks in a US-dollar account. With no conversions, the $0 brokers are free again.

Three rules Canadian day traders should know

1. There's no pattern day trader rule here. Canada never had the US$25,000 minimum. The US replaced its own rule on June 4, 2026.

2. The CRA may call it a business. If you trade often, hold for short periods and spend real time on it, your profit is likely business income. All of it is taxed, not half.

3. A TFSA isn't a loophole. The CRA has reassessed people who day traded in a TFSA and taxed their gains. Keep frequent trading out of registered accounts. More in TFSA vs cash vs margin accounts.

How to choose

• You trade Canadian stocks only: Questrade or Webull Canada.
• You trade US stocks often: Interactive Brokers, or a $0 broker with a US-dollar account.
• You use margin: Interactive Brokers, then Wealthsimple.
• You want it all at your bank: National Bank or BMO.
• You trade options: see our options platform ranking.
