Consider a parent in Ontario who earns $85,000 and supports two children. The table amount is $1,296 a month, or $15,552 a year. Add $400 a month of child care shared by income and that parent pays about $234 more, for a total near $1,530. Enter your own income and children above.
What the table amount is
Child support in Canada follows the Federal Child Support Guidelines. For most parents the amount comes straight from a table. It depends on the paying parent’s income, the number of children and the province. This page uses the Ontario table that took effect on October 1, 2025.
How the table is read
Each row covers $1,000 of income and gives a basic monthly amount plus a percentage of the income above the start of the row. At $85,000 for two children, the basic amount is $1,296, plus 1.56% of anything above $85,000. Past $150,000, the last row applies to the whole extra income.
Income that counts
The guidelines start from the paying parent’s total income as reported for tax, with some adjustments. Bonuses, self-employment income and investment income can count. Enter your yearly figure before tax. Support can be reviewed if your income changes, and the other parent can ask for updated tax returns each year.
The $16,000 threshold
The 2025 update raised the income level below which no table amount is owed, from $13,000 to $16,000. Under that, the calculator shows zero. A court can still order something in special cases. Between $16,000 and $45,000, the new amounts are often lower than the old ones.
Extra expenses
Child care, medical premiums, dental care, school fees and activities fall under special or extraordinary expenses. Parents usually split them in proportion to income. The calculator does likewise: it divides your income by the combined income of both parents, then applies that share to the monthly amount you enter.
Shared parenting
A different rule applies once a child spends at least 40% of the time with each parent. The court compares both parents’ table amounts and adjusts for the extra cost of shared care. This page does not cover it. A lawyer or a family law information centre can explain how it works in your case.
Tax and other points
Since 1997, child support has not been taxable to the parent who receives it, and the paying parent cannot deduct it. Undue hardship, very high incomes and support for adult children are handled case by case. This estimate is for information only. It is not legal advice.
Toronto and when support changes
Family courts in Toronto use the same tables as the rest of Ontario. Many parents settle by agreement and file it with the Family Responsibility Office, which collects and sends the payments. Courthouses also host family law information centres, where you can get free help with forms and next steps.
A change in income, parenting time or the number of children can justify a review. Children who stay in school past 18 may still be owed support. Keep your tax returns and notices of assessment, since both sides usually share them once a year.
Where to go next
The Canada Child Benefit calculator shows how family benefits add up. Your take-home pay is in the income tax calculator. To fit the payment into a plan, use the monthly budget calculator. Support between partners has its own spousal support calculator.
