Does Canada also have immigration supervision for elderly green card holders?

Canada also has immigration supervision for elderly green card holders. According to relevant public information, Canada requires permanent resident maple leaf card holders, which is equivalent to the green card of the United States, and must live for two years within five years after obtaining an immigrant visa to retain permanent resident status. Immigration supervision does not mean putting illegal immigrants in prison. Immigration supervision is a vivid metaphor. If you want to immigrate, you can't leave the country you want to immigrate for a long time, because if you leave for a long time, you can't apply for naturalization or lose your immigration status.
