What do you use? Remember your tax obligation as a Canadian, If you're buying US stocks paying dividends, you're paying 15% tax to uncle Sam on dividends.yeah thats the best way ...till you grow your account.
small gains..and minimize loss.
If you're buying your stocks through your TFSA..the US doesn't recognize our tax free accounts, uncle Sam is still owed his 15%. So your focus should be to buy stocks listed in the Toronto Stock Exchange first, if you can.
The only way you can avoid paying the 15% to uncle Sam is to purchase through your RRSP account (which Wealthsimple does not apply to, but if you have Questrade, you can do it)
