Hi there,
For tax purposes, the 'student' classification refers to a student with post secondary expenses, such as books or tuition or young kids that are enrolled in a qualifying institution. In most cases, there would be a T2202 document which would have been provided to you.
For more information, please refer to this article from the CRA website.

Hope this helps!
Thanks,
