Set up or update your child support online
You can set up child support or adjust the amount of child support you currently receive or pay online.
If you have questions about your online application or how to set up or update child support online, contact the online Child Support Service Contact Centre at
Respond to letter in mail
If you’ve received a letter in the mail from the Ministry of the Attorney General, it’s to let you know the other parent or caregiver of your child/children has started to set up or update child support online.
You must respond online within 25 calendar days from the date of the letter. Keep the letter on hand because you’ll be asked to enter the identification number printed at the top of the page.
If you don’t respond, the ministry may recalculate the child support amount based solely on the income information provided by the other parent or caregiver.
How to arrange child support
You can set up, update and enforce child support in one of three ways:
- Online: you and the other parent or caregiver both enter information to arrange child support
- Written agreement: you and the other parent or caregiver write an agreement yourselves, or with the help of a lawyer or mediator, to arrange child support
- Court: you and the other parent or caregiver arrange child support by filing documents in court
Calculate your child support amount
Child support payments are based on:
- the number of children
- the province or territory where the paying parent lives
- the paying parent’s annual income
Get a rough estimate of the child support amount to be paid/received using this simple calculator from the federal government.
As of November 22, 2017, Ontario is changing the provincial Child Support Tables (Schedule I of O. Reg. 391/97) to align with updates to the federal Child Support Tables. The amendments update the tables to reflect more current tax rules.
These updates could result in a small change to the child support amount required to be paid.
How to pay and receive child support
When child support is set up online or in court, it is automatically filed with the Family Responsibility Office (FRO). It helps families get the support they are entitled to by collecting, distributing and enforcing child and spousal support payments. It also determines how the money is to be paid and received (e.g. monthly through direct deposit).
If you arrange child support through a written agreement (also known as a domestic contract), you can still have FRO determine how support is paid and received.
To do this, you must:
- Submit a copy of your written agreement and a completed affidavit (a form that shows the date the agreement was submitted – and by whom) to the courthouse nearest you
- submit by mail or in person
- find a courthouse in your community
- Send a copy of your written agreement only to FRO:
- by mail:
Family Responsibility Office
Ministry of Community and Social Services
PO Box 200 STN A

- by fax:

Enforce child support
If child support payments are not made, the Family Responsibility Office has the authority to collect the money owed from the parent or caregiver who’s supposed to be paying. The FRO can use different methods such as:
- reporting the parent or caregiver who’s supposed to be paying to the credit bureau
- suspending the driver’s licence, Canadian passport or federal licence (e.g. a pilot’s licence) of the parent or caregiver who is supposed to be paying
- garnishing bank accounts
Provide proof of income
The parent or caregiver paying child support must provide the other parent or caregiver proof of income every year – and within 30 days of the original court order or agreement date.
You and the other parent or caregiver may agree to another timeframe. In that case, the paying parent or caregiver must provide the other parent or caregiver with a copy of the following:
- their last income tax return
- their last notice of assessment or reassessment for that tax return
If your order or agreement includes special expenses (e.g. orthodontics, prescription drugs, club and sports fees or child care), both you and the other parent or caregiver must provide:
- information about the status and amount of the expenses
- any loan, scholarship or bursaries the child has received or will receive in the coming year that will affect the expenses, if applicable
Withdraw child support
If you and the other parent or caregiver decide you no longer want payments to go through the Family Responsibility Office you can withdraw your support order.
