Depending on your citizenship, you may require a Temporary Resident Visa to enter Canada. This document is also called a TRV or an entry visa. A TRV is different from a study permit/work permit. It is used to enter Canada, while a study permit/work permit allows you to remain in Canada. TRVs are often issued for the same length of time as the study permit/work permit. If you have a study permit/work permit, a TRV is not needed while inside Canada, but it is a good idea to keep a valid TRV in case of sudden trips abroad.
