If required child support hasn’t arrived, or if you’re the payor who has fallen behind or can no longer manage the ordered amount, the lawful next step depends on which side of the problem you’re on. This page walks a recipient and a payor through what Ontario’s Family Responsibility Office (FRO) can do, what the courts can do, and what each reader should do now.

How child support reaches enforcement in Ontario
Ontario court support orders are automatically filed with the Family Responsibility Office (FRO) for enforcement. A domestic contract or separation agreement is different: it must be filed with an Ontario court (using Form 26B and the FRO registration package) before FRO can enforce it. FRO enforces an enforceable filed obligation; it does not create the entitlement, and it cannot change the amount in either an order or a domestic contract. Changing a court order is done through the court under section 37 of the Family Law Act; the route for changing a domestic contract can differ, and legal advice about the specific agreement is the right starting point.
When an FRO case is open, support should be paid through FRO rather than directly between the parties, and payment records should be kept on both sides.
What happens if my ex doesn’t pay child support in Ontario?
If you have an Ontario order, the first practical step is to confirm the FRO case is open and current. Parties can opt out through the legally available process, so don’t assume an older matter is still being administered.
If you are relying on a separation agreement that was never filed with the court, filing and FRO registration will usually be needed before collection can begin.
Ontario’s guidance tells recipients to contact FRO if no payment has been received for more than 30 days, and not to contact the payor’s employer directly. That 30-day instruction is administrative. It isn’t a promise about when funds will be recovered.
Denied parenting time is not a lawful reason for a payor to stop support. The two obligations are separate and each has its own remedy.
Can I report unpaid child support to FRO?
Yes. A recipient can submit a Statement of Arrears to report unpaid support, special expenses, or court costs covered by the enforceable instrument. FRO reviews the statement against the order or contract, so the amounts claimed must correspond to what the enforceable terms actually require; not every expense a recipient has incurred will qualify.
Before submitting, gather:
- the court order or filed agreement that creates the obligation;
- a complete payment record showing what was paid, when, and through which channel;
- receipts or proof for any special or extraordinary expenses you are claiming; and
- documentation of any court costs covered by the enforceable terms.
Arrears remain owing unless they are addressed through payment or a lawful court process. A recipient’s delay in enforcing support does not, by itself, erase the obligation, though limitation and procedural issues can be fact-specific. That is one reason older arrears often benefit from legal advice before a claim is finalized.
If you are the payor: falling behind or unable to meet the ordered amount
Financial hardship is a reason to seek advice and a lawful change, not permission to stop paying. Under section 37 of the Family Law Act, Ontario courts have discretion to vary, suspend, or discharge child support and to address arrears when the legal requirements are met. A payor cannot achieve that result by unilaterally reducing or ending payments.
Two points from the Supreme Court of Canada’s decision in Colucci v. Colucci, 2021 SCC 24, matter here:
- A retroactive decrease requires clear effective notice of an intended change, supported by available financial information. Simply raising the subject is not enough, and the payor carries the burden of full and frank financial disclosure. Delay and incomplete disclosure can materially limit any retroactive relief.
- Present inability to pay arrears does not by itself justify rescission. Colucci treats rescission as exceptional, available where the payor establishes that even with a flexible payment plan the debt cannot and will never be paid. Temporary suspension or a payment arrangement should be considered first.
If you have fallen behind, contact FRO promptly. Ontario’s guidance indicates a voluntary arrears payment schedule may be available while ongoing support continues. A voluntary arrangement addresses administration; it does not change the underlying order. If the amount itself needs to change, that has to go through the court.

What can FRO do to enforce child support?
FRO has a range of enforcement tools and chooses action based on the case. There is no fixed automatic ladder and no guaranteed timing. The tools include:
Deduction from income.
FRO can issue a support deduction notice to an employer or another income source so that support is deducted directly. The amount and source depend on the enforceable obligation.
Bank account garnishment.
Ontario’s guidance states FRO may take up to the amount owed from an account held only by the payor, and no more than 50% from a joint account, with a dispute process available to a joint holder. These are legislative maxima, not predictions for any specific account.
Interception of federal payments (tax refunds, EI, and other federal money).
Under the federal framework, certain federal payments can be redirected toward support, including categories such as tax refunds and Employment Insurance benefits, and federal employee, contractor, and specified pension money. These are categories the legislation allows, not a complete list or a guarantee that any particular payment will be intercepted.
Property steps.
FRO can file a lien against personal property and use writ remedies authorized by statute. Accumulating arrears can create property and credit consequences beyond ongoing deductions.
Driver’s licence.
FRO can begin a driver’s-licence suspension by notice. Suspension is not automatic on a first missed payment. Ontario’s guidance describes responses such as paying the arrears, arranging a voluntary payment plan, or seeking a court order refraining from suspension. A notice carries a deadline and needs prompt attention.
Passport and specified federal licences.
Under the federal scheme, FRO may ask that a Canadian passport, or specified federal aviation or marine licences, be denied or suspended when the statutory threshold is met. Current federal guidance describes three or more missed payments or arrears of at least $3,000. Not every professional licence is covered by this framework.
Can someone go to jail for not paying child support in Ontario?
Jail is possible, but it is not automatic and FRO does not put anyone in jail directly. It happens, if at all, through a formal court process.
FRO can require a payor to attend a default hearing by serving statutory materials and requiring financial disclosure and proof. At that hearing, under section 41 of the Family Responsibility and Support Arrears Enforcement Act, arrears and ability to pay are presumed as set out in the statute unless the contrary is shown. The court can make payment and compliance orders, require security or reporting, or direct the payor to bring a motion to change the order.
The court also has power to order imprisonment for up to 180 days, continuously or intermittently, or until the specified arrears or payment is made, whichever comes first. Imprisonment does not discharge the arrears; the debt remains.
The practical takeaway is not the worst-case number. It is that ignoring a default hearing or a disclosure obligation materially increases court risk. A payor served with these materials should bring complete financial evidence and, where possible, obtain advice before the hearing.
When one parent lives outside Ontario
FRO can enforce when one person is in Ontario and the other is in a reciprocating jurisdiction. Canadian reciprocating orders can be registered in Ontario, and orders under the Divorce Act may be sent directly to FRO as Ontario’s guidance describes. The exact procedure depends on the order, the location, and the reciprocal arrangement. Location does not necessarily end enforcement, but the correct statutory route matters.
If the other parent is in a non-reciprocating jurisdiction, Ontario’s guidance recommends obtaining legal advice about the available options. There is no universal enforcement route that reaches every country.
Take the next step that fits your situation
- If you are owed support and want to know how to move a stalled case forward: confirm your FRO case status, gather your order or filed agreement with a full payment record, and use the Statement of Arrears. Do not approach the payor’s employer. Advice helps when arrears are older or the enforceable terms are in doubt.
- If you have fallen behind or cannot manage the ordered amount: contact FRO about a voluntary arrangement, keep paying what the order requires while you act, and get advice early about a proper motion to change, with full disclosure.
- If a notice has arrived, whether it is a support deduction notice, a garnishment, a driver’s-licence suspension notice, a federal passport or licence denial or suspension, or default-hearing materials, the deadline on that notice is the priority, and advice before it expires is more useful than after.
