If your Canadian Immigration Maple Leaf Card has expired, the processing method will mainly depend on your current location and whether you meet the residence requirements for permanent residence status. Here are detailed answers for different situations:

1. If you are currently in Canada:

You can directly apply for the renewal of your Maple Leaf Card. As long as you have actually lived in Canada for a total of two years in the five years before applying for a new card, you can retain your permanent resident status and renew your Maple Leaf Card.

2. If you are outside Canada and meet the residency requirements:

If you need to enter Canada, it is necessary to show a valid Maple Leaf Card. If your Maple Leaf Card has expired, you can apply for a one-time Canadian permanent resident travel document to return to Canada. The application process is similar to that of a tourist visa, however you must meet the residency requirements for two years out of the five years prior to application.

3. If you are outside Canada and do not meet the residency requirements:

This situation is quite complicated. It is recommended not to enter the country directly because there is a possibility of revoking the permanent resident status. In this situation, the best thing to do is to consult an immigration consultant to understand the specific entry application procedures.

In addition, it is important to note that there is no correlation between the calculation of length of residence in Canada and the validity period of the Maple Leaf Card. The calculation method of residence time starts from the moment when the Immigration Bureau starts to examine you, and goes back in the corresponding direction until the time period five years ago. Generally speaking, when you apply to renew your Maple Leaf Card, when you apply for travel documents, and when you enter Canada, the Immigration Bureau will conduct relevant review work on whether your Maple Leaf Card validity period and the length of stay can meet the pre-set conditions.

Generally speaking, if your Maple Leaf Card expires, the most important thing is to determine whether you meet the residence requirements for permanent residence status, and to choose the appropriate solution based on your current location. If you have any doubts, it is recommended to consult a professional immigration consultant or lawyer.
