Do Canadian immigrants need to be handled by the whole family now?

Canadian immigrants are treated on a family basis. The applicant is called the main applicant, and the family members of the main applicant are called the deputy applicants. The so-called family members refer to the spouse and children under the age of 23 of the principal applicant.

Deal with it as a family. However, when new immigrants land, only the main applicant must go, and the deputy applicants are not required to land with the main applicant.
