Can multiple Canvas accounts be associated with the same email address?

[sadaf_alam]

I am using the Free Teacher's version, and am trying to add users to my course. I think I have it figured out, but I am wondering if one email address can have multiple Canvas accounts associated with it. Our students do not have school-issued email addresses, and many will be enrolled through their parents' emails. I wonder if this could be a potential issue for siblings?
