Questrade vs mBank: Which Broker Wins in 2026?

Questrade edges out mBank on our independent rating system, both scoring 3.3 out of 5 on the surface, but Questrade's internal scoring (3/4) outpaces mBank's (1/4) once regulatory strength and commission structure are factored in. Questrade is generally the stronger all-round pick thanks to its SEC oversight and lower per-lot commission. That said, mBank remains a compelling option for beginners who want to start without a large deposit. Your ideal choice depends on your budget, regulatory preference, and desired market access.

Both brokers advertise spreads starting from 0 pips, so pricing on the spread side is essentially a tie. The real differentiator is commission: Questrade charges just $0.01 per lot, while mBank charges $0.19 per lot. Neither broker charges deposit or withdrawal fees, so overall, Questrade is the cheaper option for active traders who execute frequent lots.

Questrade requires a $1000 minimum deposit to open an account, which may be restrictive for beginners or casual traders. mBank, on the other hand, has no minimum deposit requirement at all, making it far more accessible for those just starting out or testing strategies with limited capital.

Questrade is regulated by the SEC, a tier-1 regulatory body widely regarded as one of the most rigorous in the world. mBank is regulated by Poland's KNF, a respected regional regulator but generally viewed as carrying less global weight than the SEC. For traders prioritizing maximum regulatory assurance, Questrade holds the edge.

Questrade offers a Proprietary Web platform and a Proprietary Mobile app, covering the essentials for most traders. mBank goes a step further, supporting its Proprietary Web and Mobile platforms plus a dedicated desktop application called mBank Trader, giving users more flexibility in how they access the markets.

Yes, nothing prevents you from opening accounts with both brokers simultaneously. Many traders strategically diversify across multiple platforms to take advantage of Questrade's lower commissions for certain trades while using mBank for broader market access like ETFs and CFDs. Just be mindful of managing separate account minimums and verification requirements.

mBank provides higher maximum leverage at 1:5, compared to Questrade's more conservative 1:3 cap. Traders seeking more aggressive position sizing relative to their capital may lean toward mBank, though higher leverage also carries increased risk and should be used cautiously.

mBank supports a wider range of markets, including stocks, ETFs, CFDs, indices, and forex — five categories in total. Questrade covers stocks, forex, indices, and commodities, totaling four categories. If diversified asset access is a priority, mBank has a slight structural advantage.

Questrade was founded in 1999 in Toronto, Canada, giving it a one-year head start over mBank, which was established in 2000 in Warsaw, Poland. Both brokers have multi-decade track records, so longevity is not a major differentiating factor between the two.
