感谢大家帮助。我是在CIC网上看了以下陈述才来求证的 " y2 _( {+ a+ O& _1 `0 i- @ " | L1 T/ G8 S6 J$ h6 TIf you leave Canada and want to return, you must have: . K: U4 B8 k' k6 Y/ ?$ z0 D# f6 @ T' Z# K2 C) ?

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...# Z9 t' ^5 F7 b1 u1 j- o* H

Maybe someone can call CIC 1888-242-2100 for confirmation.
