Canada allows many types of people to be sponsored under the Family Class.
They are:
• Spouses: (married/ living together/ conjugal partners)
• Children: Dependent children who are under the age of 22 and are unmarried can be sponsored. As well, children who are over 22 and those who are married can also be sponsored, if they can prove they are full-time students and are financially dependent on the sponsor.
• Adopted Children: A person who is under 18 and whom the sponsor wants to adopt in Canada can be sponsored.
• Parents: Obviously, parents of the sponsor. And parents may also bring their dependent children with them.
• Grandparents
• Orphans: An orphan is described as someone whose parents are both deceased. An orphaned sibling, grandchild or a nephew or niece can be sponsored if they are under the age of 18 and are unmarried.
• Other Relatives: If the sponsor does not have any spouse, child, parent, sibling, grandparent, aunt, uncle, nephew, or niece living in Canada, and no relative living abroad who can be sponsored, then the sponsor may sponsor any other relative regardless of their age.
