Questrade vs Interactive Brokers (2026): Which Is Better for Canadian Traders?
The classic Canadian multi-asset question. Both are CIRO-regulated; they suit very different levels of experience. Both are regulated by CIRO and both carry CIPF protection up to CAD $1 million, so this is not a safety comparison — it is a fit comparison. Here is how they actually differ.
How we make money & how we research
We may earn a commission if you open an account through some links on this page, at no cost to you. We do not test brokers with live-funded accounts; our ratings are built from regulatory records (CIRO, CIPF, provincial regulators), public disclosures, and documented broker terms. See our methodology and affiliate disclosure. Trading forex and CFDs carries a high risk of loss.
The short answer
Questrade if you want a straightforward Canadian home for investing and trading, with registered accounts for the investing side. Interactive Brokers if you are experienced, trade actively across markets, and will use the access and pricing enough to justify the platform’s complexity.
Both are CIRO-regulated and CIPF-protected. Trading involves risk of loss.

Figures change. Minimum deposits, spreads and commission schedules are set by the brokers and revised periodically — always confirm the current numbers on the broker’s own site before you open an account. Our full reviews of Questrade and Interactive Brokers go deeper on each.
Regulation and safety
Both firms operate through Canadian entities registered with the Canadian Investment Regulatory Organization. That means segregated client funds, capital adequacy requirements, complaint and dispute-resolution processes, and CIPF coverage of up to CAD $1 million per account category if the firm becomes insolvent.
It is worth stating plainly what CIPF does and does not do. It protects against the failure of the dealer. It does not protect you against losing money on your trades — nothing does. A regulated broker is a floor, not a guarantee of outcomes.
You can verify both firms’ current registration independently with our CIRO broker checker, and we would encourage that rather than relying on any comparison page, including this one.
Platforms
Questrade offers Questrade Trading, QuestMobile, third-party platform options. Registered accounts — TFSA and RRSP — for its investing products, plus a full Canadian multi-asset offering.
Interactive Brokers offers Trader Workstation, IBKR Desktop, Client Portal, mobile, extensive API. Unmatched market access and among the most competitive cost structures for high-volume traders.
Both firms provide demo accounts. Given that platform preference is largely a matter of how a given interface fits the way you think, spending a week in each demo will tell you more than any amount of reading — including this page.
Costs
Questrade: Published commission schedule that varies by asset class. Interactive Brokers: Tiered and fixed commission structures with published rates.
The comparison that matters is total cost on the specific pairs you trade, at your actual volume, including any inactivity or withdrawal fees. A tighter headline spread can be more expensive once commission is added, and a commission structure can be cheaper for a frequent trader than a wider spread-only quote. Pull the current published schedules for both, apply your own monthly volume, and compare the total.
Do not overlook currency conversion. If you fund in CAD and the account is denominated in USD, you pay a conversion cost at both ends that can easily exceed the spread difference you were optimising for. Our tax guide covers why this matters at filing time too.
Who each one suits
Questrade fits canadians who want investing and trading in one place, with registered accounts for the investing side. Its main limitation is that forex is a secondary line rather than the core product; the specialist forex platforms are more capable.
Interactive Brokers fits experienced, active or multi-market traders who value access and cost over simplicity. Its main limitation is that trader Workstation has a genuinely steep learning curve and is overbuilt for casual users.
If you are still undecided, our broker quiz narrows it down by what you actually trade, and the full comparison table covers every CIRO-regulated option rather than just these two.
Frequently asked questions
Is Questrade or Interactive Brokers better for Canadian traders?
Neither is better in the abstract — they suit different traders. Both are CIRO-regulated and CIPF-protected, which means the safety question is settled for both. Questrade tends to suit canadians who want investing and trading in one place, with registered accounts for the investing side. Interactive Brokers tends to suit experienced, active or multi-market traders who value access and cost over simplicity. The right answer depends on what you actually trade and how often.
Are both Questrade and Interactive Brokers legal in Canada?
Yes. Both operate through CIRO-regulated Canadian entities and client assets are covered by CIPF up to CAD $1 million in the event of insolvency. You can confirm current registration yourself using the CIRO broker checker rather than taking anyone’s word for it, including ours.
Which has lower costs, Questrade or Interactive Brokers?
It depends on what and how much you trade. Spread-only pricing tends to favour lower-frequency traders; commission-based pricing with tighter raw spreads tends to favour high-volume traders. Both firms publish current schedules, and those schedules change — check them directly for the specific pairs you trade before deciding.
Can I have accounts with both?
Yes, and some traders do. There is nothing preventing you from holding accounts at more than one CIRO-regulated broker, and it can make sense if you want different platforms for different purposes. The practical costs are the time spent managing both and the additional record-keeping at tax time.
Does either offer TFSA or RRSP accounts for forex?
Registered accounts are generally not available for leveraged forex and CFD trading, because those positions do not fit within the qualified investment rules. Some brokers offer registered accounts for their conventional investing products while excluding forex. Our guide to forex trading taxes in Canada explains why this restriction exists.
