If you are talking about the AuthorizationRep form for a T1, you open a T1 tax file, fill out the name and SIN on INFO form, check mark the Enable Printing mark at the top of the AuthorizeRep form and check mark the box on Representative Information and authorization section ( I assume The info has been populated on EFILE Options Preparer already) , and select the level of authorization then put an expiry date if it applies. Once the form is filled out, you can click on EFILE Efile Authorization form menu.
