This paper explores the factors considered by Canadian court judges in 14 cases where the provincial legislation that obligates adult children to provide support for their parents was referred to. This exploration takes place within the context of intergenerational relationships with a focus on exchange between parents and adult children. Analysis revealed that the courts promote the obligation of family members to provide for one another according to the legislation and that the responsibility to provide this support is based on certain priorities. Nuclear family obligations come before those of the extended family. Of the factors considered by the court, this paper focusses on three: the eligibility of the parent, who is initiating the court proceedings, and the definition and prioritizing of responsibilities between parents and adult children.
