你們都是加拿大的永久居民,那你們一定有Landing paper(Confirmation of Landing?). 自己開車的話,沒有楓葉卡,有Landing paper也是可以的.可打電話到Canada Immigration and Citizenship詢問.
我自己的經驗:
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.
