Account maintenance

Changes in your business may result in changes to the data you provided to us at the time you applied for, or last renewed your participation in, electronic filing

An account maintenance option is available to all registered users of EFILE.

If you are a discounter, you must also contact the Discounter and e-Services Projects Section at 613-941-8864 to advise them of changes to the information you previously provided for discounting purposes.

To modify your account information for electronic filing, sign in with your EFILE Number and password and select "Maintain account" on the resulting webpage.

When you maintain your account, you will see your current EFILE account information. Since we use this information to contact you throughout the year, please ensure that the following information is current:

The system will verify the submitted form and will generate error messages, if applicable. Make any required corrections, and resubmit the form. Once the form has been accepted and your account updated, the system will display a confirmation page, similar to the following example.
