Best Discount Brokerage in Canada 2026: DIY Platforms Ranked

The Ranking: Best Discount Brokerages in Canada for 2026

Here is the short version before the detail. There is no single "best" brokerage for everyone — there is a best brokerage for your situation. The table below ranks the major Canadian self-directed platforms by who they fit, not by a single score, because the right choice for a 28-year-old building a first TFSA is not the right choice for a retiree drawing a RRIF or an active options trader.

A note on the numbers in that table: commission schedules in Canada move constantly, and the fee figures change without much warning. That is exactly why this ranking leans on the structural model (commission-free vs. per-share vs. flat-fee) and account fit, rather than quoting a dollar-per-trade that may be stale by the time you read this. Always confirm the live commission and fee schedule on the broker's own page before you open.

1. Wealthsimple — The Best Default for Most Canadians

For the typical Canadian DIY investor — someone building a TFSA, RRSP, or FHSA out of a couple of broad ETFs and checking in a few times a year — Wealthsimple is the brokerage to beat. The pitch is straightforward: zero commission on Canadian and US stock and ETF trades, no annual administration fee on its core self-directed accounts, and a mobile-first interface that does not assume you speak finance.

It covers every registered account a household needs: TFSA, RRSP, FHSA, RRIF, and non-registered. That matters because the account you hold an investment in does more for your after-tax return than the ticker you pick. A globally diversified ETF inside a TFSA grows and comes out entirely tax-free; the same ETF in a non-registered account hands the CRA half of every capital gain at your marginal rate — up to 53.53% in Ontario at the top bracket. Wealthsimple makes filling that registered room as low-friction as it gets.

The trade-offs are real and worth naming. The research and charting tools are basic compared to Questrade or Interactive Brokers. There are no US-dollar registered accounts, so US holdings inside a TFSA or RRSP get converted to and from Canadian dollars, and that currency conversion has a cost. And the security universe is narrower — fine for ETFs and large-cap stocks, limiting if you trade niche instruments. For a buy-and-hold portfolio, none of those matter much. For an active trader, they add up.

2. Questrade — The Upgrade for Hands-On Investors

Questrade is the platform you graduate to when Wealthsimple starts to feel too simple. ETF purchases are commission-free; stock trades carry a small per-share commission. What you pay for is depth: stronger charting, more order types, a broader security universe, and — the feature that wins over a lot of investors — US-dollar registered accounts.

That US-dollar account is not a gimmick. If you hold US-listed ETFs or stocks inside a TFSA or RRSP, a CAD-only platform converts your dollars on every buy, every sell, and every dividend. A US-dollar registered account lets you fund it once in US dollars and trade without repeated conversion drag. For an investor with meaningful US exposure, that can save real money over time.

Questrade covers the full registered lineup — TFSA, RRSP, FHSA, RRIF — just like Wealthsimple. The reasons to choose it over Wealthsimple come down to three things: you want US-dollar registered accounts, you want better tools, or you trade often enough that the order-type flexibility matters. If none of those describe you, the simpler, fully commission-free option is the better call.

3. The Big Six Bank Brokers — Convenience at a Price

TD Direct Investing, RBC Direct Investing, BMO InvestorLine, Scotia iTRADE, CIBC Investor's Edge, and National Bank Direct Brokerage are the brokerage arms of Canada's major banks. Historically they charged a flat per-trade commission well above the independents, plus a quarterly administration fee unless you held a minimum balance (often in the $15,000–$25,000 range) or set up automatic contributions.

The competitive pressure from Wealthsimple and Questrade has pushed several of them to cut fees — National Bank Direct Brokerage in particular moved to commission-free trading earlier than its peers — so the gap is narrower than it once was. But on a strict cost basis, the bank brokers are usually still the more expensive choice.

What you get for the premium is integration. Money moves instantly from your chequing account to your brokerage; everything sits under one login; and if you want to walk into a branch and talk to a human, you can. For some people that consolidation is worth a few dollars per trade and is the single thing that gets them to actually invest rather than leaving cash idle. That behavioural benefit is legitimate. Just go in knowing you are paying for convenience, not performance — the bank broker does not buy you better returns, only a smoother login.

4. Interactive Brokers — For the Power User Only

Interactive Brokers (IBKR) sits at the opposite end from Wealthsimple. It offers very low tiered or per-share pricing, the cheapest margin rates in the market, and access to a global universe of stocks, options, futures, and currencies. For a high-volume trader, an options strategist, or someone running a US-heavy book, nothing in Canada is more cost-effective.

The catch is the same as its strength: complexity. The platform assumes you know what you are doing. The interface is dense, the account setup is more involved, and the feature set will overwhelm a first-time investor. IBKR does support Canadian registered accounts including TFSA and RRSP, but it is not where you want to learn. If you are building a simple buy-and-hold TFSA, IBKR is the wrong tool — it is a professional's platform, and you would be paying in cognitive overhead for capabilities you will never use.

The Decision That Actually Moves Your Money: Account Before Platform

Here is the part most brokerage comparisons skip. The difference between the cheapest and most expensive platform on this list is, for a typical buy-and-hold investor, a handful of dollars a year. The difference between holding your investments in the right account versus the wrong one is hundreds or thousands of dollars a year. Choose the account sequence first, then the platform.

Run the math on why this order matters. Say you hold an investment that throws off a $2,000 capital gain in a year. Inside a TFSA, you keep all $2,000. In a non-registered account at Ontario's top 53.53% marginal rate, only half the gain is taxable (the 50% inclusion rate), so you are taxed on $1,000 — roughly $535 to the CRA, leaving $1,465. Same investment, same platform, same gain: the account it sits in decided whether you kept $2,000 or $1,465. No commission difference between brokerages comes close to that swing.

What About Halal Investors? The Platform Is Neutral — The Holdings Are Not

Muslim investors can use any of the brokerages on this list, because a brokerage is just the account that holds your investments — it is Shariah-neutral. What determines compliance is what you buy inside it, and here the default choice trips most people up.

The broad-market index ETFs that nearly every discount-brokerage portfolio is built on — the popular all-in-one asset-allocation funds and S&P 500 trackers — generally fail the AAOIFI Shariah screen. They hold conventional banks and insurers whose interest-bearing debt and impermissible income breach the AAOIFI Standard 21 limits (interest-bearing debt and cash-plus-interest-securities each capped at 30% of market cap, impermissible income capped at 5% of total income). Cash balances sitting in the brokerage account also typically earn interest, which is riba.

The fix is not a different platform — it is different holdings. A Muslim investor opens the same self-directed TFSA or RRSP at Wealthsimple or Questrade, then buys purpose-built Shariah-screened ETFs or individually screened stocks instead of the default index fund, and purifies any incidental impermissible income. For the full screening logic and a ranked list of compliant funds, see our guide to the best halal ETFs in Canada.

How to Actually Choose — A 60-Second Decision Path

1. Buy-and-hold, want the lowest cost and least hassle? Wealthsimple. Open a TFSA, buy a globally diversified all-in-one ETF, set up automatic contributions, done.
2. Hold meaningful US stocks/ETFs, or want better tools? Questrade, for the US-dollar registered accounts and deeper platform.
3. Already bank with a Big Six and value one login? Your bank's brokerage — accept the slightly higher cost as the price of integration, and check whether they have cut fees recently.
4. Trade frequently, use margin, or trade options/US markets heavily? Interactive Brokers, and only then.
5. Investing as a Muslim? Any of the above — just buy Shariah-screened holdings, not the default index ETFs.

The Bottom Line

For the majority of Canadians in 2026, Wealthsimple is the best discount brokerage — it costs the least, covers every registered account, and gets out of your way. Questrade is the better choice if you want US-dollar registered accounts or deeper tools, the Big Six brokers earn their premium only through same-bank convenience, and Interactive Brokers is the specialist's tool for active traders.

But the platform is the smallest decision you will make. Whether you keep $2,000 or $1,465 on a $2,000 gain comes down to the account, not the broker. Whether you build wealth or bleed it slowly comes down to the MER on what you hold, not the commission on the trade. Pick the account order first, keep your fund costs low, then choose whichever platform on this list fits how hands-on you want to be.
