Students wishing to study in Canada for less than 6 months are not required to have a study permit. If you want to work on or off campus, however, you must have a Canadian study permit. A visitor permit issued at a port of entry will not be sufficient.
If you are considering staying longer than six months, you should apply for a study permit before entering Canada. For information on how to apply please visit this website.
