New 2025 Child Support Tables in Ontario: Does Your Existing Order Change?

If you already pay or receive child support in Ontario, you may have heard that the child support tables changed. It is natural to wonder whether your monthly amount is now wrong, and whether someone will adjust it for you.

This article explains which tables apply to which period, what the new Ontario figures look like, and the two main ways to update an order or agreement. Your own numbers depend on your facts, so a lawyer can confirm what applies to you.

What changed on October 1, 2025

Updated Federal Child Support Tables took effect on October 1, 2025. The 2025 tables apply to support owed from that date onward, and the 2017 tables apply to support owed from November 22, 2017 to September 30, 2025.

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

Depending on income and the number of children, the new amounts may be lower or higher than under the 2017 tables. The only way to know for your situation is to compare your current order with the 2025 table.

Does my existing order change automatically?

No. The 2025 tables do not automatically change an existing order made before October 1, 2025. Your current amount stays in place until it is formally updated.

There is a useful link, though. 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. Under the Divorce Act, a court can vary a child support order only after it is satisfied that a change of circumstances has occurred since the order was made or last varied. Any change that would result in a different child support order counts under the Guidelines.

The Divorce Act applies to married spouses who are divorcing. Unmarried parents, and married parents not seeking a divorce, are governed by Ontario's own family law statute and guidelines, so it is worth confirming how the rules apply to your family.

Sample 2025 Ontario table amounts

These are monthly amounts from the 2025 Ontario table at the start of each income band.

Amounts inside each income 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 for one child is $450 plus 1.26% of income over $50,000.

Above $150,000, the top row adds a percentage to the $150,000 amount, and a court may use a different approach if the full table amount seems inappropriate. No child support is payable under the tables by a payor whose annual income is below $12,000. Special or extraordinary expenses under section 7 are paid on top of the table amount.

Two ways to update your support

Ontario's online Child Support Service can set up or update child support without going to court, but only in some situations. It issues a Notice of Calculation or Recalculation that is sent to FRO for enforcement. The fee is a non-refundable $80 each time, and a fee waiver is possible for low-income households.

You cannot use the online service in several situations:

• Parenting time is shared or split.
• A parent or child lives outside Ontario.
• A child is over 17.5 or married.
• The order involved undue hardship or imputed income.
• The payor is self-employed, earns over $150,000 or under $12,000, earns cash income, or is a partner or majority shareholder in a business.

If the online service is not available, you can go to court. The forms are Form 15 to ask for a change without the other parent's consent and Form 15D where both consent, along with a Form 13 financial statement. Proof needed includes three years of tax returns, notices of assessment and proof of current income. If you were unemployed in the last three years, you must also file a Record of Employment or other proof and a statement of any benefits still owed, such as severance.

What FRO can and cannot do

FRO cannot change the amount owed; only a judge can. Arrears keep building under the existing order until it is changed. The recalculation service can also update the amount, as noted above.

This matters if the new table helps you. A recipient whose amount would go up, or a payor whose amount would go down, should not assume the change is happening in the background. The old amount keeps applying until the order is updated. Payors who lose their job should contact FRO immediately.

What to do next

• Find your current order or agreement and note the date it was made, the income used and the amount.
• Find the 2025 table amount for the paying parent's current income and number of children, and compare.
• Gather three years of tax returns and notices of assessment, plus proof of current income.
• Check whether any online service exclusion applies, such as shared parenting or self-employment.
• Decide whether to apply online or in court, and whether the other parent is likely to consent.
• Speak with a lawyer if your situation is complicated, such as shared parenting, business income or income over $150,000.
