If it says that your NETFILE account is locked, then there is nothing we can do as NETFILE is a CRA service that we do not control.

If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency
