That's great wynona! Don't loose that piece of paper what ever you do! And keep it.....forever! I'm serious.

You may need it later.
No, I would not fax it to the CRA's just yet. If I were you, I'd wait at least 30 days, even 60, and then pull my CR's and check to see if it's been removed. If it has no further action is needed.
I don't think a CRA would delete the baddie based on what you send them at this point. But that's just my opinion.
