I am not sure what the difference between SDRRSP (Self Direction RRSP) and RRSP. I know I could borrow the RRSP loan if I buy RRSP, but not for SDRRSP. The advantage of SDRRSP is I can make the decision what I want to buy and I do not need to pay the RRSP management fee to the RRSP broker.
Another question is how I could open a SDRRSP?
