你们都是加拿大的永久居民,那你们一定有Landing paper(Confirmation of Landing?). 自己开车的话,没有枫叶卡,有Landing paper也是可以的.可打电话到Canada Immigration and Citizenship询问.
我自己的经验:
1.Move to Canada in 2005. Two adults had maple card. Little daughter did not have maple card and held US passport. She got a entry permit at the port.
2.Went to Canada in June,2011. My wife lost her maple card. She used her landing paper. The custom officer let her enter without any questions.
