Hello, my dear friend, I am very honored to serve you: Even if Canadian permanent residents have lived in the country for less than two years, as long as the maple leaf card has not expired, they can still enter Canada. However, if the identity holder has lived in Canada for less than 730 days in the past five years, they may be deemed to have lost their permanent resident qualification. As for whether the maple leaf card can be renewed after it expires, it needs to be judged based on the specific circumstances. As long as you meet the entry conditions of the Canadian Immigration Department and can provide sufficient and reasonable explanations and evidence of the reasons why you are not living in Canada, you may have the opportunity to apply for an extension of the maple leaf card. However, each case will be evaluated based on its unique situation, so it is recommended that you consult the Canadian immigration department or Canadian embassies and consulates abroad for specific matters, and to know in detail the application conditions and procedures for renewing the maple leaf card.
