A license subscription whose status is "Already canceled" means that it is not going to be renewed after its expiration date, but can still be used until the expiration date comes.
Please note that at the expiration date, all users will be automatically dropped out from courses they got enrolled in via the subscription in question.
A license subscription whose status is "Expired", cannot be used anymore. The users that are enrolled in the courses included in the subscription are not getting dropped out of them once the subscription expires.
