Yes... but at that level of capital you also have to ask yourself whether you want to be trading individual securities or if a passive approach would suit you better, in which case TDW also offers you access to their low-cost e-series mutual funds. I'm also a happy TDW customer.
If you do want a cheaper broker then Questrade looks to be the cheapest option, and there are some referral codes around to give you a few free trades to start you off, too.
Definitely use your TFSA room first (you'll have $10k of total room in a few days time).
