It is best to change your address with the Canada Revenue Agency (CRA) before filing with your new address. If it is not changed at the CRA when you try to Netfile, you will not be eligible to do so due to the difference of address. Please see this CRA page to change your address. Please make sure your address has been changed before trying to Netfile.
