Child support is one of the most important financial issues separating parents must navigate, and recent changes to the Federal Child Support Tables will affect how support amounts are determined in Ontario and across Canada. These updates, which took effect on October 1, 2025, reflect the first comprehensive revision to the tables since 2017 and were designed to align support amounts with current tax rules and economic conditions.
Under Canadian family law, most child support orders and agreements use the Federal Child Support Guidelines, which include a set of tables that determine the basic monthly support amount based on the paying parent’s income, number of children, and province of residence. In Ontario, these federal tables are the standard reference for calculating parenting support after separation or divorce.
One major change in the 2025 update is the adjustment of the income threshold. The updated tables start the child support obligation at an annual income of $16,000, up from $13,000 in the 2017 version. This means that parents earning below $16,000 per year may now have a basic table amount of zero, though special or extraordinary expenses could still apply.
For parents in the $16,000 to $45,000 income range, the new table amounts tend to be lower than under the 2017 tables. On the other hand, for higher-income parents, the changes are generally minor, often a small adjustment up or down, usually within 1–2 % of the previous amounts.
It’s important to understand that existing child support orders or agreements do not automatically update to reflect the new tables. If your current order is based on the old table amounts, it remains in effect until you take action. However, if the updated table produces a significantly different amount, that difference could be considered a material change in circumstances, which may allow you to request a recalculation or apply to the court for a variation of the support order.
In practical terms, this means that both payors and recipients should review their current child support arrangements in light of the updated tables. Parents negotiating a new agreement or preparing for a court application after October 1, 2025 should use the 2025 Federal Tables to calculate the base amount. Simplified versions of the tables and online lookup tools are available to help estimate support levels, but the official legal version remains the authoritative source.
Finally, remember that the table amount is just the starting point. The Federal Child Support Guidelines also allow for additional contributions toward special or extraordinary expenses, such as childcare, medical costs, or educational activities, that are shared proportionately based on parental income.
