Self Directed RRSP trustee in Alberta

[Cynthia Ganga]

I'm getting the run around from private wealth management firms that I've talked to about starting an RRSP to invest in small businesses and property. It's allowed by CRA but I'm finding it hard to find a trustee (company that manages the paperwork). 

Any suggestions? 

This needs to specifically be BOTH small business shares in private corporations and mortgages or property.
