If you leave Canada and want to return, you must have:
A valid passport or travel documents A valid study permit if you are returning to
study in Canada A valid temporary resident visa if you are a citizen of a designated
country for which Canada requires a visa.
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 require 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 must re-apply for a temporary resident
visa at a Canadian visa office outside Canada before you can re-enter Canada.
