按照以前的规定，是需要更换的。
但是，现在只是primary school跟high school是需要更换study permit. post-secondary是不用的。
援引CIC原话如下：
Post-secondary student
You may change your school, program, field of study or level of study (e.g. from the Bachelor level to the Masters level) 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.
