One of the lowest minimum commission ($10) out there and cost/fess is important because they eat into your return especially when you just started to invest. Yes, it is a custodian account but there is really not much difference unless if you want to attend AGM. Otherwise, you will still be able to participate in all the relevant corporate actions (dividends, rights, etc.) at no additional cost. There are other brokerages that charge custodian fees, dividend handling fees, etc...
Continue to invest and build your portfolio until it is > $200,000 and you get to become a priority customer with the bank. As a priority customer, there will be no minimum commission :) I can always enter/buy rights, illiquid stocks without buying a minimum commission.
