Section 3(2) of the FCSG provides that if the child is over 19 but still a “child of the marriage” in need of support: (a) the amount determined by applying the Guidelines as if the child were under 19; or (b) if the court considers that approach to be inappropriate, the amount that it considers appropriate, having regard to the condition, means, needs and other circumstances of the child and the financial ability of each spouse to contribute to the support of the child.

When determining whether a child over the age of majority who is pursuing post-secondary education is still a “child of the marriage” for support purposes, the court considers factors such as the contribution of the child to their education, the reasonableness of career plans and the parents’ plans for the education of their children before the breakdown of the marriage: See a longer list of factors in Farden v. Farden .
