While a study permit authorizes international students to pursue their studies while in Canada, a Temporary Resident Visa (TRV) allows a person to enter Canada. Depending on the country of citizenship, an international student may need a TRV for entry.
For overseas applications, applicants from countries whose citizens require TRV in order to enter Canada will be issued a TRV automatically if the application for a study permit is approved. These applicants do not need to submit a separate application for a TRV and there is no separate fee. The same applies to applicants from countries whose citizens need an Electronic Travel Authorization (eTA) in order to enter Canada by air.
