This paper digests 10 of the most frequently cited judicial decisions on child support rendered by courts of appeal in Canada in the past 3 years. The decisions address aspects of the Federal Child Support Guidelines, SOR/97-175 [Guidelines], that tend to be most prone to litigation, including imputing income (ss 18–19), support for adult children (s 3), special expenses (s 7), and averaging income (s 17). Other provisions highlighted in the cases include retroactive support orders, incomes in excess of $150,000, and shared custody. In addition, a summary discussion of some of the key Guidelines-related issues is also provided.
