I see you are in Canada and things may be different there, but in the UK it is simple - student has the form that they will use to apply for their licence from the beginning of their training and the examiner enters the marks from each exam as they are done - since the student keeps the form there is no problem moving to another school and the situation you are in should not arise. I suggest you find out if the system is supposed to be the same where you are and, if it is, get the exam marks entered on a form asap.
(as has been discussed elsewhere it may be not so easy to get the other student records however)
