Instructors can export their course content using this Guide:
Then, an instructor could create a Free For Teacher (FFT) account and upload the course export file to a course in his/her FFT account.
How do I import a Canvas course export package?
However, as you may know, the FFT account would have some limitations compared to a paid Canvas account that is at your school or business. (By the way, I don't believe there is any way for an individual to purchase a Canvas environment for himself/herself.) You'll want to review the comparison PDF document that is linked in this Guide:
Canvas Free-for-Teacher FAQ (canvaslms.com)
I hope this will be of some help to you. Sing out if you have any questions...thanks!
