I used up my 5 NETFILE tries to submit my tax returns. Is my account locked for 24h or permanently until I contact CRA?

You will have to contact the Canada Revenue Agency (CRA) to get unlocked. 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
