What is the test for awarding section 7 expenses for child support purposes?

[57] In awarding section 7 expenses, the trial judge calculates each party’s income for child support purposes, determines whether the claimed expenses fall within one of the enumerated categories of section 7 of the guidelines, determines whether the claimed expenses are necessary “in relation to the child’s best interests” and are reasonable “in relation to the means of the spouses and those of the child and to the family’s spending pattern prior to the separation.” If the expenses fall under clauses 7(1) (d) or (f) of the guidelines, the trial judge determines whether the expenses are “extraordinary”. Finally, the court considers what amount, if any, the child should reasonably contribute to the payment of these expenses and then applies any tax deductions or credits. See: Titova v. Titov, 2012 ONCA 864.
