I don't think that is correct, PMM
Your family members are your spouse or common-law partner, if applicable, and your dependent children (start with the oldest). You must include all of your family members (who are not already permanent residents of Canada or Canadian citizens), whether they intend to immigrate with you or not. Any other relative (your mother, father, sister or brother, for instance) is not considered a family member for the purpose of this application. If you have more than three family members, attach a separate sheet of paper with the same information provided in the same order
See the guide, "Details of Family Members"
