TD RESP - do I need to keep my bank account with them?

Hi guys.

I've been with TD since forever. I've also opened an RESP for my kid with them a few years ago.
Now I'm in the process of switching my checking and savings accounts over to another bank and I wonder: will I be forced to also close my RESP with TD or can I keep that as the only service I have with them?
The RESP is not via TD Waterhouse. It's with TD Bank itself.

Thanks!
Thought I'd ask here before I call them and have them try to BS me into not closing my other accounts.
