If you've just gotten a support order — or you're on the paying end of one — you've probably heard the name before you understood what it actually does. The Family Responsibility Office, known as FRO, is the Ontario government body that collects and enforces child and spousal support. Understanding how FRO works upfront saves a lot of confusion once your case is enrolled.

This guide covers what FRO is, how a case gets opened, what happens once it's running, and what its enforcement powers actually look like.

What FRO Is and Where It Comes From

FRO was established under the Family Responsibility and Support Arrears Enforcement Act, 1996, and it exists to make sure court-ordered — and certain agreement-based — child and spousal support actually gets paid. It doesn't decide how much support is owed; that comes from a court order or a filed domestic contract. FRO's job starts once that amount already exists.

How a Case Gets Enrolled

Every Ontario support order, and every domestic contract with support terms that has been filed with the court, is automatically enrolled with FRO. You don't need to apply separately — enrollment happens as part of the order or filing process itself.

Once enrolled, FRO typically works alongside a Support Deduction Order, which directs the payor's income source (usually an employer) to deduct support directly from their pay and send it to FRO, which then forwards it to the recipient.

What Happens After Enrollment: The Basic Cycle

  1. The order or agreement is filed, triggering automatic FRO enrollment.
  2. A Support Deduction Order goes out to the payor's employer or other income source, where applicable.
  3. Payments are deducted and sent to FRO, which forwards them to the recipient.
  4. FRO tracks the case, including any arrears that build up if payments are missed or incomplete.
  5. If payments stop or fall short, FRO can use its enforcement tools to collect what's owed.

FRO's Enforcement Toolkit

When a payor falls behind, FRO doesn't need to go back to court for a new order before acting — it has its own set of enforcement tools, including:

These tools can be used individually or in combination, and FRO generally escalates as arrears persist rather than jumping straight to the most severe option.

What Recipients Can Expect

What Payors Can Expect

Common Misunderstanding: Support and Parenting Time Are Separate

Support and parenting time are legally distinct issues, each enforced through its own process. A parent can't lawfully withhold parenting time because support isn't being paid, and a payor can't lawfully withhold support because parenting time isn't happening as agreed. If either issue is a real problem, it needs to be addressed on its own terms — support through FRO or a support variation, parenting time through the family court process.

Frequently asked questions

Do I have to apply to FRO separately after getting a support order?

No. Enrollment with FRO happens automatically once a support order is made or a domestic contract with support terms is filed with the court — there's no separate application step.

What if my ex and I have a private agreement that isn't filed with the court?

An informal agreement that hasn't been filed doesn't get FRO's automatic enforcement. If you want FRO involved, the support terms generally need to be part of a court order or a domestic contract that's been properly filed.

Can FRO change how much support I pay or receive?

No. FRO enforces the amount set out in the order or agreement — it doesn't have authority to change that amount. If circumstances have changed, a motion to change the order is the correct process, not a request to FRO.

What should I do if I'm falling behind on payments?

Contact FRO and consider whether a motion to change the underlying order is appropriate given your circumstances. Waiting quietly tends to let arrears — and the enforcement response to them — build up rather than resolve.

How do I update my information with FRO?

Both payors and recipients are generally expected to keep FRO informed of changes like address, employment, or banking details, since that information affects how deductions and payments are processed.
