I do not have CRA Account and i sent my T1 for the first time with two of my friends in one package and one of my friend have got the acknowledgement from the CRA end.
If you don’t have a My Account and you want to check
on the status of your tax return, you will still need to contact the CRA. If
you are in Canada or the United States, you can call the CRA at 1-800-959-8281.
If you are somewhere else you can call 613-940-8495. Here are more ways to
contact the CRA:
