Glad to know you already applied.
Changing Course
After reaching canada if you are changing schools and/or your program of study but remain at the same level (e.g., secondary level), you do not need to modify your study permit.
However, if for example you are a student at the primary school level and you are moving on to secondary school, or if you are a secondary school student and you are moving on to post-secondary studies, or if you are moving from post-secondary studies to secondary studies, you need to submit an application to modify your study permit at the Citizenship and Immigration Canada Case Processing Centre in Vegreville, Alberta.
Note: If you are a student at the post-secondary level, and you are moving from a bachelor’s to a master’s (or vice versa), or a master’s to doctorate studies (or vice versa), you also need to submit an application to modify your study permit at the Citizenship and Immigration Canada Case Processing Centre in Vegreville, Alberta.
Job
It is possible to work in Canada while you are here as a student, and there are opportunities for jobs on and off campus. You will need to apply.
1. You may work on campus at the institution where you study without a work permit.
2. You may work off campus but to qualify for the program, you must already hold a valid study permit, and you must have been a full-time student at a participating institution for at least six of the last 12 months before you apply.
However it is easy to find job in Ontario province if you got off campus work permit and some special skills.
