Temporary Resident Visa (TRV)
Temporary Resident Visa (TRV), also referred to as a “visitor visa” or “entry visa,” is a travel document that is placed in your passport and is used to enter or re-enter.
It does not give you any status inside the country and is usually issued for the same length of time as your study or work permit. A TRV allows you to travel to a country (that is, to the border), while a study permit will enable you to stay and study inside that country. A study permit is a document showing your status, but you must have a valid TRV to enter if you are a citizen of a visa-required country.
If you’re a citizen of a visa-required country, you will need a TRV to travel to or re-enter Canada.
If you are from a visa-exempt country, you will need an Electronic Travel Authorization (eTA) to travel by air.
Once you are in that country, you are not required to have a valid TRV since it is only for entry. However, it is highly recommended to always have a valid TRV in the event of an unexpected trip abroad. Otherwise, you must apply for a TRV from outside. It may take a long time, and you may not be able to return in time.
