Can I go back to Canada? Can I still apply for renewal or membership change of Maple Leaf Card?

First, you have the right to enter Canada within the validity period of the maple leaf card. Even if the customs has doubts about your residence time, he must allow you to enter Canada for legal procedures. Only if the legal procedure fails can he let you leave the country within a time limit.

Second: When the customs has doubts about you, you'd better prepare sufficient reasons, such as family reasons, to win the sympathy and recognition of customs officials, who can have the right not to conduct further investigation on your situation, so that there will be no trouble at all. When you enter the customs, the customs officers will definitely ask you why you have to walk so long. You can also try to take the self-service entry channel without manual inspection.

Third: the invalidation of maple leaf card will not affect your legal residence in Canada at all, and immigration paper is the key, so keep the immigration paper at all times and you can use it to reissue the maple leaf card at any time.

Fourth: you can't change your card if you haven't lived for 5 years or 2 years. You just need to continue to live for 2 years.

Fifth: you need to return the maple leaf card when you are naturalized, regardless of whether the maple leaf card is invalid or not.
