Hogwarts School of Continuing Education?

Today I received a Hogwarts Acceptance Letter sent to me from Canada. Canada Hogwarts. ???

There was no context except a note from Dumbledore (beyond the grave, at that):

Dear Miss K. Dietrich,

I have been informed by the MINISTRY that your Acceptance letter has been in their possession from some time and that you have, unfortunately, never received it.  I offer you my apologies and hope that you are still seeking a magical education.  Please report to Professor Flitwick who will be overseeing the courses for older students. Forward your reply no later than July 31st.

Albus Dumbledore


I'm confused.

**EDIT**


Chelsea sent it!! How lovely is she?  It's from Etsy. I mean Hogwarts.
