Leaving and coming back to Canada
If you leave Canada and want to return, you must have:
a valid passport or travel document
a valid study permit if you are returning to study in Canada and
a valid temporary resident visa, if you are a citizen of a designated country for which Canada requires a visa. The list of designated countries can be found in the Related Links section at the bottom of this page.
Note: If you are a citizen of a designated country and you travel to a country other than the United States, Greenland or Saint-Pierre et Miquelon, you need a multiple-entry visa to re-enter Canada. If your temporary resident visa has expired, or if your visa was only valid for a single entry, you will have to re-apply for a temporary resident visa at a Canadian visa office outside Canada if you want to re-enter Canada.
