I had a couple of recurring transactions set up on my credit card. I then had a call from MBNA telling me of some potential fraud on my account. As a precaution they cancelled my card and issued me with a new number. My recurring transactions continued as before despite both the card number, expiry date and CCV number changing.
So it seems cancelling your card will not stop transactions like these.
