Key takeaways
  • A drop in the payor's income after a job loss can count as a change of circumstances that lets you ask for a new amount.
  • The Family Responsibility Office cannot change what you owe, and arrears keep building under the existing order until it is changed.
  • Be ready to prove your income, because the proof needed in court includes three years of tax records, and a court can impute income in some cases.

Losing your job or taking a pay cut does not reduce your child support. The order you signed or were given stays in place until it is formally changed, and the payments keep coming due whether or not the money is there.

This article explains how a change usually works in Ontario, what proof you will need and why acting quickly matters. It is general information, not advice on your own order, so a lawyer can confirm how it applies to you.

Why waiting makes things worse

Many payors assume the Family Responsibility Office (FRO) will adjust the amount once they explain their situation. It cannot. FRO cannot change the amount owed; only a judge can, and arrears keep building under the existing order until it is changed.

FRO also asks payors who lose their job to contact it immediately. Telling FRO is not the same as changing the order, but it keeps them informed while you start the process to change it.

A court can vary an order prospectively or retroactively, but it is not guaranteed to go back in time for you. The safest assumption is that the sooner you apply, the less unpaid support piles up in the meantime.

When a lower income counts as a change

Under the Divorce Act, a court may vary, rescind or suspend a child support order on application by either or both former spouses, but first it must be satisfied that a change of circumstances has happened since the order was made or last varied. Any change that would result in a different child support order qualifies, and a drop in the payor's income after a job loss is a named example.

That test comes from the Divorce Act. How it applies if you were never married, or are married but not seeking a divorce, depends on your situation, so it is worth confirming with a lawyer.

Courts do not simply accept a lower number, though. A court may impute income if a spouse is intentionally under-employed or unemployed, or unreasonably deducts expenses from income. There is an exception: income is not imputed where the under-employment or unemployment is required by the needs of a child, or by the spouse's reasonable educational or health needs.

In plain terms, being laid off and looking hard for work looks very different from quitting a well-paid job. How a court sees your situation depends on the facts.

Ways to ask for a change

RouteWhat it involvesLimits
Online Child Support ServiceCan update child support without court and issues a Notice of Recalculation sent to FRO; the fee is a non-refundable $80 each time, with a fee waiver possible for low-income householdsNot available in several situations, such as a self-employed payor, income over $150,000 or under $12,000, shared or split parenting, or a parent or child outside Ontario
Court, with consentForm 15D is the form where both parents consentBoth parents must agree
Court, without consentForm 15 asks for a change without the other parent's consentYou must prove the change in circumstances

If you go to court, you will usually also file a Form 13 financial statement with a Form 13A certificate of financial disclosure. If your payor income is under $12,000, no table child support is payable at that level under the federal tables, but whether that applies to you depends on your whole situation.

What proof you will need

Proof needed in court 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, along with a statement of any benefits still owed, such as severance.

If you are self-employed, expect to provide three years of financial statements and a breakdown of payments to non-arm's-length persons as well. Courts may look at income over the last three years where income varies.

What to do next

Frequently asked questions

Will my child support go down automatically if I lose my job?

No. FRO cannot change the amount owed, only a judge can, and arrears keep building under the existing order until it is changed. You need to apply for a change.

Can the court reduce support for the months I already missed?

A court may vary an order prospectively or retroactively, but only after it is satisfied there was a change of circumstances. Whether it goes back, and how far, depends on the facts, so applying early matters.

Can I use the online Child Support Service to ask for a lower amount?

Sometimes. It can update support without court for a fee of $80 each time. It is not available if, for example, the payor is self-employed, earns cash income, or parenting time is shared or split.

What if the court thinks I could earn more than I do?

A court may impute income if a spouse is intentionally under-employed or unemployed. It will not do so where the situation is required by a child's needs or the spouse's reasonable educational or health needs.
