Some Agency told me,If you want to change the Program after Visa Approval, it can only be done after I Enter Canada and The Embassy needs to be Informed about the Change and it would be to the Embassy's Discretion to allow that Change or not.
However, Citizenship And Immigration Canada Website Says:
•You may change your school, program and/or field of study without applying for a new study permit. You do not need to apply for a change to the condition of your study permit, either. You may continue to use your study permit as long as it is valid.
•If you are changing your level of study (e.g., bachelor’s to master’s), you do not need to apply for a change to the condition of your study permit, either.
