Privacy Matters: Who Has Access to Your Financial Information?

I just received a cold call from a representative at TD Waterhouse (TWE Quote), my online broker. The person was trying to sell me something. She said she'd been looking over my portfolio. My question is: Just who at an online broker has that kind of access to my account? What gives Waterhouse the right to let strangers look at my holdings? Isn't this private information?
