If you are currently studying in Canada on a study permit and you want to change your program of study, you will generally need to submit a new study permit application. This is because your current study permit is only valid for the program of study that is listed on the permit. If you want to change your program of study, you will need to apply for a new study permit that is specifically authorised for the new program.
There are a few exceptions to this rule. If you are currently studying in Canada on a study permit and you want to change your program of study within the same institution, you may be able to do so without having to submit a new study permit application. However, you will still need to inform Immigration, Refugees and Citizenship Canada (IRCC) of the change in your program of study and make sure that your study permit reflects the new program of study.
It is important to note that even if you are able to change your program of study without having to submit a new study permit application, you may still need to meet the eligibility requirements for the new program of study. This means that you may need to meet any academic or language requirements that are specific to the new program.
In general, it is a good idea to consult with the institution that you are attending or with IRCC before making any changes to your program of study. This will help ensure that you have all of the necessary information and documents in order to successfully change your program of study and continue studying in Canada.
