Ontario Child Support Table: Monthly Amounts for 1, 2 and 3 Kids

If you are separating, one of the first questions is usually simple: how much child support is normal? In Ontario, for many families the starting point is a government table that links the paying parent's income to a monthly amount for one, two or three children.

This article gives sample amounts from the Ontario table at common income levels and walks through worked examples. The numbers are a guide only. Your own figure can differ because of extra expenses, parenting time and how income is measured, so treat this as a starting point for a conversation with a lawyer, not a final answer.

What the table is and how it is used

The basic child support amount depends on three things: the number of children, the province where the paying parent lives, and the paying parent's annual income. For children under the age of majority, the usual order is the table amount for the number of children and the payer's income, plus any special or extraordinary expenses.

The updated Federal Child Support Tables, including Ontario's, came into effect on October 1, 2025. For earlier periods the 2017 tables apply. The figures below are from the 2025 Ontario table.

Sample Ontario monthly amounts

The table below shows the monthly amount at several annual incomes of the paying parent. These come from Schedule I (Ontario) of the Federal Child Support Guidelines.

At $150,000 and above, the amounts shown are the base figure, and a percentage of income over $150,000 is added: 0.76% for one child, 1.22% for two children and 1.54% for three children.

Worked examples

Incomes rarely land exactly on a round figure. The table method is: monthly amount equals the basic amount plus a percentage of the income above the listed figure. The brackets are $1,000 wide, so incomes between brackets are worked out in between.

• One child, income of $60,500: $554 plus 0.92% of the $500 over $60,000, which is $558.60 a month.
• One child, income above $150,000: $1,327 plus 0.76% of the income over $150,000.
• Two children, income above $150,000: $2,135 plus 1.22% of the income over $150,000.
• Three children, income above $150,000: $2,781 plus 1.54% of the income over $150,000.

These examples use the amounts in the table above. Justice Canada's simplified Ontario tables are rounded, so the official tables or the online look-up tool give the exact figure.

What the table amount leaves out

The table amount is only part of the picture. Several things can change what is actually ordered.

• Special or extraordinary expenses: either parent can ask for things like child care tied to work or school, the child's share of health insurance premiums, health costs over insurance by at least $100 a year, extraordinary school or extracurricular costs, and post-secondary education costs. Basic table calculators usually leave these out.
• Shared parenting: if each parent has the child at least 40% of the time over a year, the amount is not simply the table amount. The court looks at both parents' table amounts, the higher costs of shared care and each parent's circumstances.
• Undue hardship: on a parent's application, a court may award a different amount if a parent or child would otherwise suffer undue hardship.
• High income: where the payer earns more than $150,000, the court uses the table unless it considers that inappropriate, in which case it uses the table amount for the first $150,000 plus an amount it sets for the rest.
• How income is measured: a court can impute income, for example where a parent is intentionally under-employed, so a calculator using a declared income may differ from a court's figure.

The tables change over time

The tables were updated to reflect more recent tax rules. Earlier versions were 2006, 2011 and 2017, so there is no fixed update schedule. That means any chart you find online may be out of date, so check the date it applies to.

The 2025 tables do not automatically change orders made before October 1, 2025. A different table amount may count as a change in circumstances, and a parent can apply to court or a recalculation service to update the amount.

What to do next

• Write down the paying parent's most recent annual income from the tax return, and note any bonuses, self-employment or corporate income.
• Use the federal look-up tool, which Ontario also recommends for a rough estimate, to check your figure.
• List any child-related costs that might count as special or extraordinary expenses, with receipts.
• Work out the real parenting schedule over a full year, since 40% or more changes the analysis.
• If you have an older order, check whether it pre-dates October 1, 2025, and speak with a lawyer about whether an update makes sense.
