questrade - US$ RSP account fee change
Reduced USD in RSP commission fees
If you currently hold U.S. cash and trade USD securities in your TFSA, RRSP, spousal RRSP, or LIRA, the $5.00 U.S. flat-per-day commission fee payable each day you trade USD securities no longer applies.
LIFs, RIFs, spousal RIFs, and RESPs cannot directly hold U.S. dollars. These accounts will continue to hold USD units with each unit equal to one U.S. dollar. A $5.00 U.S. flat-per-day commission is applied each day you trade USD securities no matter how many trades you make. If you make no USD trades on a particular day no commissions are charged.
