That may depend on what you want to do with the information.
If the student's enrollment in a course was actually "deleted", then there is no information to show unless they are restored to the course. If they are "concluded", then their information remains but may be hidden. The document Canvas enrollment status comparison explains the difference between the enrollment states.
If you just want to see which students were formerly in the class, you can go to Course Settings, Sections, and then pick the section the student was enrolled in. At the bottom will be "completed enrollments". If you click on their name, you can pull up grades or analytics about that user.
From the People page, you can click the three vertical dots at the top and choose "show prior enrollments". This gives a list of the prior users and their score, but little else. You can click on the student's name and be taken to their user page for the course. From there, you may be able to restore or delete the enrollment (this depends on permissions and your institution may control the enrollments). Viewing prior enrollments does not add them to the People page, it takes you to another page with the list of prior enrollments.
From the Grades page, you can click the dropdown at the top left that says Gradebook and change it to "Individual Gradebook". There is an option there to "Show concluded enrollments." You can then stick with the individual view or switch back to the "Traditional Gradebook". The concluded enrollments will not appear in the gradebook along with any grades they have.
