How Much Child Support Will I Pay in Ontario? 2025 Table Amounts

If you are separating or divorcing, one of the first questions is how much child support will be paid each month. In most cases the starting point is a set table, not a negotiation from scratch. The goal of the Guidelines is a fair standard of support and less conflict between spouses.

This article explains how the 2025 Ontario table amounts work, with figures at several income levels. These are the amounts at the start of an income band, so your own figure may differ slightly. A lawyer can confirm how the rules apply to your situation.

What the table amount depends on

The basic amount of child support is the amount in the applicable table for the number of children under the age of majority. Any special or extraordinary expenses under section 7 are added to it. The table amount depends on the paying parent's annual income, the number of children and the province where the paying parent lives.

Ontario's government says the new table amounts apply to all Ontario child support matters starting October 1, 2025. There is an exception for orders made before October 1, 2025. The 2025 tables do not automatically change an existing order, but a difference between the old amount and the 2025 table amount may count as a change in circumstances. That lets a parent ask a court or the recalculation service to update the order.

2025 Ontario table amounts (monthly)

These monthly amounts come from the 2025 Ontario table. Each is the amount at the start of the income band.

Amounts inside a band are calculated as the base amount plus a percentage of income above the band's start. For one child, for example, the $50,000 to $50,999 band is $450 plus 1.26% of income over $50,000.

Under the federal tables, no child support is payable by a payor whose annual income is below the $12,000 threshold.

Incomes over $150,000

The top row of the Ontario table is $1,327 plus 0.76% of income over $150,000 for one child, $2,135 plus 1.22% for two children, and $2,781 plus 1.54% for three children.

The court may order the full table amount. If it considers that amount inappropriate, it may instead use the table amount on the first $150,000 plus an amount it considers appropriate for the income above that.

How income is measured, and which tables apply

Income for child support is the annual income set out in sections 15 to 20 of the Guidelines. It starts from Total income on the T1 General tax return and is adjusted under Schedule III. If income varies, for example in seasonal work or self-employment, the court may look at the last three years to find a fairer figure.

• Use the 2025 tables for support owed from October 1, 2025 onward.
• Use the 2017 tables for November 22, 2017 to September 30, 2025.
• An order made before October 1, 2025 does not change automatically. A difference between the old amount and the 2025 table amount may count as a change in circumstances, which lets a parent ask a court or the recalculation service to update the order.

Other things that can change the amount, and next steps

Section 7 expenses, such as child care or certain medical and education costs, are paid on top of the table amount. If each parent has at least 40% of parenting time over a year, the court does not simply use the table. It considers the table amounts for each parent, the increased costs of shared parenting and each household's circumstances. Split parenting applies when there is more than one child and each parent has a majority of parenting time with at least one of them. In that case, support is the difference between the table amounts each parent would otherwise pay the other.

• Gather your last three years of tax returns and notices of assessment.
• Note the paying parent's current income and the number of children.
• Record the parenting-time schedule you actually follow.
• List child care, medical and school costs you want to raise.
• If you have an existing order, compare it with the 2025 table and speak with a lawyer about whether to ask for an update.
