A permanent resident card is a special card that's given to individuals who have been granted the status of permanent resident. This means they can live in Canada indefinitely, even though they haven't become citizens. The card serves as official proof that they have the right to stay in Canada and have access to various privileges like working, studying, as well as accessing healthcare services. It's an essential identification document, especially when they're traveling in and out of Canada, as it shows immigration officials and other authorities that they have legal permission to enter the country.

This card is crucial for anyone holding permanent resident status in Canada.
