If the cancellation is not due to fraudulent charge, I would not bother to cut it. Once an account is closed, the charge could not go through unless from those "pre-authorized" types such as recurring bill payments.
Now if the cancellation is because you need a new card number due to fraudulent charges, charges made under the cancelled number would still go through for a while and carry over to the new number.
