Immigration Legislation requires that an application for a study permit be accompanied by a letter from a Designated Learning Institution accepting the applicant to attend or to take any course at that institution. The letter should be recently issued and should outline the
type of course of study or program you are registered for,
the start date and the expected completion date, and
whether the program is full-time or part-time studies.
As you have not provided such evidence your application cannot be approved.
