How is child support calculated in Canada?
Under the Federal Child Support Guidelines the basic amount is read from a table. There is a separate table for each province and territory, and the one that applies is generally the one where the paying parent lives. The table is keyed to the paying parent's annual income and the number of children. Income is listed in $1,000 bands; the monthly amount is the band's basic amount plus a percentage of the income above the band's lower limit. Schedule I gives a worked example for British Columbia, 2 children and $51,250: $807 + 1.54% of $250 = $810.85, and this tool reproduces it.
What changed in 2025. The updated tables came into force on 1 October 2025. Justice Canada says a parent with income of $16,000 or less now has a basic table amount of $0, and that orders made before 1 October 2025 are not updated automatically. Child support under the tables is not taxable to the parent who receives it and not deductible by the parent who pays it.
Worked example. In Ontario at $60,000 a year, one child comes to $554.00 a month and two children to $911.00 a month. The table stops at $150,000. Above that, section 4 sets the table amount for the first $150,000 and leaves the court to decide the balance. This tool shows the "$150,000 or greater" row of Schedule I as an estimate and the table amount at $150,000 beside it.
Frequently asked questions
How much is child support in Ontario?
It depends on the paying parent's income and the number of children. Using the 2025 Ontario table, a parent earning $60,000 pays $554.00 a month for one child and $911.00 a month for two. At $100,000 it is $932.00 for one child and $1,984.00 for three. Special expenses under section 7 are separate.
Do the tables use the paying parent's income only?
Yes. Section 3 of the Guidelines bases the table amount on the income of the spouse against whom the order is sought. The other parent's income matters for special expenses (section 7), for shared parenting time (section 9) and for undue hardship.
What if the paying parent earns more than $150,000?
Section 4 says the court can use the table amount, or, if it finds that inappropriate, the table amount for the first $150,000 plus whatever it considers appropriate for the balance. For example, Ontario with 2 children at $200,000 shows $2,135.00 for the first $150,000 and $2,745.00 if the Schedule I formula row is carried on.
Does my existing child support order change automatically?
No. Justice Canada says the updated table amounts do not automatically apply to an order made before 1 October 2025. You can ask to recalculate or vary the order.
Which province's table is used?
Generally the table for the province or territory where the paying parent habitually lives when the application is made (section 3(3)). The Guidelines add rules for a parent who has moved or is about to move, or who lives outside Canada.
