Material Change in Circumstances in Ontario

A material change in circumstances may justify changing an Ontario support or parenting order. The legal test depends on the kind of order and the change since the court last decided it.

A job loss or a child’s changed needs can support an application, but the evidence must satisfy the relevant test. Compare the present circumstances with those underlying the existing order before filing a motion to change.

Support and parenting use different variation rules

The Divorce Act lets a court vary support, parenting, and contact orders, but it uses different tests for each one. Section 17(4) governs child support, section 17(4.1) governs spousal support, and section 17(5) governs parenting orders and contact orders (section 17 of the Divorce Act).

Ontario provincial parenting orders use the terms decision-making responsibility, parenting time and contact. The Children’s Law Reform Act provides the provincial best-interests and variation rules.

Check the legislation and any review provision governing your existing order. A scheduled review can have a different scope from a variation based on a material change.

Spousal support under section 17(4.1)

In L.M.P. v. L.S., the Supreme Court confirmed the material-change threshold for varying a spousal support order, including a consent order. The change must be one that, if known when the order was made, would likely have resulted in different terms.

The justices applied the approach in Willick v. Willick. Compare the present spousal support circumstances with the facts underlying the order or its last variation.

Check What the Order Already Took Into Account

Under the Justice Canada variation guidance, the required change is substantial and continuing. Focus on what the parties actually contemplated or took into account rather than rejecting an event simply because it was foreseeable.

Retirement can be foreseeable without its financial consequences having been settled in the earlier order. The terms of the order and any incorporated agreement help establish what was already considered.

Child support under section 17(4) and the Guidelines

Under section 17(4), the court applies the variation conditions in the applicable child support guidelines. For an order based on a support table, section 14 of the Federal Child Support Guidelines includes a change that would produce a different order or provision.

For an order without a table determination, section 14 addresses changes in the condition, means, needs or other circumstances of a spouse or a child entitled to support. Income, parenting arrangements and a child’s expenses can affect child support obligations.

When the Court Can Impute Income

Under section 19, a court may impute income where the rule permits it. Intentional underemployment is one ground, with exceptions for a child’s needs and a spouse’s reasonable educational or health needs.

A lower salary does not automatically establish intentional underemployment. Provide evidence explaining the change in employment and earning capacity.

Parenting orders under section 17(5) and Gordon v. Goertz

In Gordon v. Goertz, the Supreme Court addressed a material change affecting the child before a fresh best-interests inquiry. Current parenting legislation must also be considered when reviewing what older orders call child custody arrangements.

Divorce Act section 17(5) addresses changes in the child’s circumstances since the order or last variation. Section 17(5.2) deems relocation of a child a change, while subsection (5.3) limits that rule where a court has prohibited the relocation.

The child’s best interests determine the parenting outcome. A parent’s request alone does not establish that the proposed arrangement should replace the existing order.

Timing matters, but not because the law sets a fixed delay

A motion to change does not require a universal three-month or six-month waiting period after a final order. Assess the evidence against the applicable test, including the substantial and continuing change needed for a spousal-support variation.

The existing order remains binding unless it expires under its terms or is lawfully changed, suspended or set aside. Filing a motion does not itself reduce support payments, and unpaid amounts can become arrears.

Record the Change and Give Notice

Keep the dated termination letter, income records or other documents showing what changed. For a job loss, record replacement income and reasonable efforts to find work; for a health-related loss, obtain relevant evidence of work limitations.

Communicate the proposed change and provide the required disclosure without unnecessary delay. If you cannot meet the existing obligation, obtain advice about available relief rather than assuming you must wait several months.

What counts and what does not

Income, Health and Retirement

A layoff or health condition may affect income and support needs. Explain the financial effect, expected duration and what the existing order already took into account.

Retirement requires the same comparison with the prior order. Age alone does not establish the outcome, and a voluntary income reduction may require evidence about why it was reasonable.

A Child’s Needs, Care and Safety

Changed education or health expenses can affect support. A changed parenting schedule or a child’s relocation requires consideration of the applicable parenting and support rules.

Evidence of family violence can be relevant to a child’s safety and best interests. Explain its effect on the child and the proposed parenting arrangements.

A New Household or Changed Financial Resources

A new common-law relationship can affect household expenses, but it does not automatically end spousal support. The court considers the financial evidence and the basis for the existing obligation.

Financial resources connected with property division may be relevant to support. A support variation does not itself reopen a completed property division.

Why Disagreement With the Old Order Is Insufficient

A variation is generally not an appeal of the original result. Identify the relevant change rather than asking the judge to reconsider the same facts.

If the concern involves fraud or missing disclosure when the order was made, a different legal remedy may apply. The appropriate procedure depends on the alleged defect.

Agreements, orders, and mediation are not the same thing

A separation agreement or cohabitation agreement can affect the support analysis. If its terms became a court order, L.M.P. v. L.S. requires the statutory variation test while considering what the agreement shows the parties took into account.

Changing an agreement that has not become a court order may involve a different legal test. A review clause can also define the issues and timing of a review, so read the actual document before choosing the procedure.

Mediation or arbitration may help resolve a dispute where appropriate. An agreement reached through divorce mediation does not, by itself, vary an existing court order.

How the Ontario motion to change process works

For a disputed change, follow Ontario’s requirements for documents, court issuance, service and proof. Use the current forms and check the directions for your court location.

1. Prepare Form 15 and the existing order. Identify the changes requested and explain the supporting facts. Include the filed agreement if that is the document you are asking to change.
2. Add the required financial or parenting evidence. Support requests generally require Form 13, income records and Form 13A. Parenting requests may require Form 35.1.
3. Have the court issue the motion. Submit the required package and obtain the issued copies before service.
4. Arrange service and file proof. Follow special-service requirements and serve any agency entitled to notice. File the required proof of service.
5. Follow the response and court directions. A disputed case may involve conferences, further disclosure and a hearing. Consent cases use the appropriate consent procedure, which can differ for child-support-only changes.

Disclosure Is Required From the Relevant Parties

The applicant must establish the basis for the requested variation. That burden does not remove the respondent’s applicable financial-disclosure duties.

Provide the records required for the particular claim. For retroactive changes or cancellation of arrears, provide income evidence covering the affected years as required in Ontario’s guidance.
