How Much Is Child Support in Ontario at Common Incomes

Parents often want a realistic number before they talk to the other parent or a lawyer. In Ontario, the starting point is the child support table, which sets a monthly amount based on the paying parent's income and the number of children.

This article gives examples from the 2025 Ontario table at common income levels, explains how to read them and lists what can move the figure up or down.

How to read the table

The table amount depends on the paying parent's annual income, the number of children and the province where the paying parent lives. Updated tables took effect on October 1, 2025, and apply to support owed from that date onward. Ontario's government says the new amounts apply to all Ontario child support matters starting that date.

The figures below are monthly amounts at the start of each income band. Amounts inside a band are slightly higher, because each band adds a percentage of income above its starting point. For example, the $50,000 to $50,999 band is $450 plus 1.26% of income over $50,000 for one child.

Monthly examples for one, two and three children

The one-child figures are $450, $695, $932 and $1,327 at the four income levels. The two-child figures are $744, $1,144, $1,517 and $2,135. The three-child figures are $1,003, $1,501, $1,984 and $2,781.

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

Incomes above $150,000

For income 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.

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

What can change the number

The table amount is the starting point. Several things can push the real figure up or down:

• Special or extraordinary expenses, paid on top of the table amount, such as child care or extraordinary extracurricular costs.
• Shared parenting, where each parent has at least 40% of parenting time over a year, which has no automatic formula.
• Split parenting, where the difference between each parent's table amount is payable.
• Undue hardship, which can lead to a different amount, though it must be denied if the claiming household has a higher standard of living.
• The income figure used, since the court can consider three years of income, corporate income or imputed income.

Section 7 expenses are shared in proportion to the spouses' incomes, after deducting any contribution from the child. For child care, the court must first take into account subsidies, benefits, income tax deductions or credits, so the after-tax cost is what gets shared.

If your order was made before October 1, 2025, it does not automatically change. A difference between the old amount and the 2025 table amount may count as a change in circumstances that lets a parent ask for an update.

Getting a figure you can rely on

An example from a table is only as good as the income behind it. Income starts from Total income on the T1 General tax return and is adjusted under Schedule III. Gather three years of tax returns and notices of assessment, which are needed in court along with proof of current income.

• Find the paying parent's most recent tax return and notice of assessment.
• Estimate the children's child care, health and school costs for the year.
• Write down the real parenting schedule over a year.
• Ask a lawyer to confirm the income figure if there is self-employment, a company or irregular pay.

Ontario's online Child Support Service can set up or update child support without court, but it is not available in every situation. For example, it cannot be used if parenting time is shared or split, or if the payor is self-employed or earns over $150,000. Whether it fits your situation is worth confirming with a lawyer.

Support is also tax-neutral in the usual case. Child support under a court order or written agreement made after April 1997 is not deductible by the payer and is not included in the recipient's income.
