25. A family is composed of
(1) an adult and the adult’s dependent children;
(2) spouses and their dependent children or the dependent children of either spouse; or
(3) spouses who have no dependent children.
Despite the first paragraph, a person remains, ceases to be or becomes a member of a family in the circumstances determined by regulation, and an adult who does not meet the eligibility requirements set out in section 26 or to whom paragraph 2 of section 27 applies is not considered a member of a family.
