In Ontario the majority of child support payments are enforced by the Family Responsibility Office (FRO) if the payments are made pursuant to a court order or a registered domestic contact, unless the parties have withdrawn their file from the FRO.
The support obligation in Ontario, unlike other jurisdictions, is not automatically extinguished under the law when the child turns 18.
There are two ways to cease the enforcement of child support. If both the payor and the recipient agree that the support should be terminated, they can file their consent with the FRO and the FRO will close the file accordingly.
If the parties can’t agree whether the support obligation should end, there’s nothing the FRO can do. Instead, the support payor must bring a motion to change before the court that granted the child support payments in the first place.*
It’s perhaps a good idea to discuss the proposed termination with the recipient to find out whether a consent order to terminate child support could be a possibility. If so, the support payments may be terminated without the parties’ attending the court by way of a consent motion. If not, the support payor will have to ask the court to change or terminate the support.
