What is the difference between my study permit and visitor visa?
Your study permit is the piece of paper folded into your passport. It allows you to stay in Canada for the purpose of studying until a specified date. If you plan to continue studying after the expiry date, you must begin the extension process two months before it expires. Your visitor visa or temporary resident visa (TRV) is a sticker in your passport required to enter Canada only. Some countries do not require visitor visas. If you plan on leaving Canada and then returning, you will need a valid visitor visa.
