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 will 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 must re-apply for a temporary resident visa at a Canadian visa office outside Canada before you can re-enter Canada.
I remembered I saw this policy somewhere before... + i! a2 `4 ]) S E9 [& Z: \# ]) O! K% Q0 @5 C R q
