CAN I USE A TAX FREE SAVINGS ACCOUNT (TFSA) TO TRADE STOCKS THROUGH A CANADIAN BANK?

I haven’t paid for or sole holds before, so my subject is two-fold.
I listened of the TFSA, as well as that we can use it to have taxation giveaway income, as well as you’re authorised up to 5 k per year in brand new principal capital, or 10 k if it’s your initial time.
My question, can I use this income to buy holds upon the US or Canadian Stock Markets?
If so, how do I set this up? Can I buy holds online around Scotia Bank or do I have to use the little alternative website to buy as well as sell stocks?
I do not have the TFSA yet, though what I’ve found from the Scotia website is that they often suggest holds or scotia mutual funds, that I’m not as well meddlesome in removing in to during the moment…..
I would goal there is the approach to set it all up with Scotia as well as buy from there, though if not I’d similar to to know how to traffic in holds whilst receiving value of this TFSA.
