Certain entry requirements are necessary depending on where you come from and the reason for your visit. Visitors to Canada, including tourists, students, and workers, may need a Temporary Resident Visa (TRV) from Immigration, Refugees and Citizenship Canada (IRCC) to enter Canada. There are some countries which we refer to as visa-exempt countries. These are the ones that do not need a TRV to enter Canada on a visit. These countries are determined by the Federal Government of Canada.
