A family court order is based on the circumstances that exist when it is made. Whether the order deals with parenting arrangements, child support, spousal support, or another ongoing family law matter, the court makes its decision based on the evidence available at that time.
Life, however, rarely remains the same. A parent may lose a job, receive a promotion, relocate for work, retire, or experience health challenges. Children grow older, their educational and social needs change, and parenting schedules that once worked well may no longer be practical. Financial circumstances can also improve or decline in ways that neither party anticipated.
Ontario family law recognizes that these changes can happen. Rather than requiring families to follow an order that no longer reflects their circumstances, the law provides a process for asking the court to review certain aspects of an existing order. That process is known as a Motion to Change.
Before returning to court, it is important to understand whether a Motion to Change is the appropriate legal process for your situation.
Family law is unique because many court orders continue to affect people for years after they are made. Parenting arrangements may remain in place until a child reaches adulthood, while child support or spousal support obligations can continue for many years depending on the circumstances.
It would be unrealistic to expect every family to remain exactly the same throughout that time.
Children who were toddlers when an order was made may now be entering high school. Parents who once lived in the same community may now work in different cities. Financial circumstances can improve dramatically or decline unexpectedly through no fault of either party.
The courts understand that these developments are part of life. At the same time, they also recognize the importance of stability. If court orders could be changed every time someone became dissatisfied with the outcome, families would face constant uncertainty and repeated litigation.
For that reason, Ontario courts generally require evidence that something significant has changed before they will consider modifying an existing order.
A Motion to Change is a legal procedure to ask the court to vary or update an existing family court order, or in some cases a domestic contract that has been incorporated into a court order.
Unlike the original court proceeding, a Motion to Change does not start the family law dispute from the beginning. Instead, it asks whether the order should be varied because circumstances have materially changed since it was made.
This distinction is important. The court is not deciding whether the original judge made the right decision based on the evidence available at that time. Instead, it is asking a different question: Does the existing order still make sense in light of today's changed circumstances?
That difference is what separates a Motion to Change from an appeal, a distinction that many people misunderstand.
One of the most important concepts in any Motion to Change is the idea of a material change in circumstances.
In simple terms, this means the change must be significant enough that it could have affected the original order had it existed when the judge made that decision. Generally speaking, the change should be significant rather than minor, ongoing rather than temporary, and something that was not reasonably anticipated when the original order was made. The court considers each family's circumstances individually, but the underlying question remains the same: does the existing order still reflect the family's current reality?
Minor inconveniences or temporary setbacks will not usually justify changing a court order. Instead, the court looks for meaningful changes that have altered the family's circumstances in a lasting way.
A substantial increase or decrease in income may justify reviewing child support. A child developing new educational or medical needs may affect parenting arrangements. Retirement, disability or long-term illness may influence support obligations. Likewise, if one parent plans to move a considerable distance away, the existing parenting schedule may no longer be practical.
Every case is different. What constitutes a material change in one family may not satisfy the legal test in another. This is one reason why obtaining legal advice before bringing a Motion to Change is often worthwhile.
A Motion to Change is not an opportunity to argue that the judge reached the wrong decision during the original case. Ontario courts expect family court orders to provide stability and finality, and they will generally not reconsider issues that have already been decided unless there has been a genuine material change in circumstances.
If your concern is that the judge misunderstood the evidence, misapplied the law, or made an error when issuing the original order, a Motion to Change is usually not the appropriate procedural step to take. In those situations, an appeal may be the better legal option. Understanding this distinction can help avoid unnecessary delays, expense, and frustration.
While every family's circumstances are unique, there are several situations that commonly give rise to a Motion to Change in Ontario family law.
One of the most frequent involves child support. Child support is generally based on the paying parent's income, so a significant increase or decrease in earnings may justify reviewing the existing order. A job loss, career change, retirement, disability, or the receipt of a substantial promotion may all affect the amount of support that should be paid. Similarly, as children grow older, expenses related to education, extracurricular activities, or post-secondary schooling may also change.
Changes involving parenting arrangements are another common reason families return to court. Children do not have the same needs at age five as they do at age fifteen. School schedules become more demanding, extracurricular commitments increase, and children often become more independent. A parenting schedule that once worked well may become increasingly difficult to manage. In other situations, one parent may wish to relocate, or ongoing conflict between the parties may make the existing arrangement unworkable.
Changes involving spousal support can also justify a Motion to Change. A recipient may become financially self-sufficient, while the person paying support may experience retirement, illness, or an unexpected reduction in income. In some cases, a significant improvement in one party's financial circumstances may lead to a request that support be reduced or terminated. In others, a substantial decline in financial resources may result in a request to increase support.
The common thread in each of these situations is that the court is not reconsidering the original decision simply because one party wishes the outcome had been different. Instead, the court is assessing whether the facts have changed enough that the existing order is no longer appropriate.
One of the most common misconceptions in family law is that a Motion to Change and an appeal accomplish the same thing. They do not.
An appeal asks a higher court to review whether the original judge made a legal, factual, or procedural error when making the decision. The focus is on whether something went wrong during the original hearing. Appeals are subject to strict deadlines, and the appeal court generally reviews the existing record rather than hearing the case all over again.
A Motion to Change, on the other hand, accepts that the original decision may have been entirely correct when it was made. The issue is not whether the judge made a mistake but whether the family's circumstances have changed enough that the order should now be updated.
A simple example illustrates the difference. Imagine that child support was correctly calculated based on a parent's annual income of $95,000. Two years later, that parent unexpectedly loses their job and begins earning significantly less. The original judge did not make an error; the order accurately reflected the evidence available at the time. However, the parent's financial circumstances have now changed substantially, making a Motion to Change the appropriate legal process.
Conversely, if a party believes the judge misunderstood the evidence or incorrectly applied the law when making the original order, an appeal may be the more appropriate legal remedy.
Understanding this distinction before beginning legal proceedings can save considerable time, expense, and frustration.
Every Motion to Change follows its own path, but the process generally begins with a careful review of the existing order and the circumstances that have changed since it was made.
Before commencing a court proceeding, it is important to gather documentation that supports the requested change. Financial records, income tax returns, employment information, medical reports, school records, or other relevant evidence may all play an important role depending on the issues involved. The stronger the evidence demonstrating the material change in circumstances, the better positioned the court will be to understand why the existing order should be varied.
Once the appropriate court materials have been prepared and served, the other party has an opportunity to respond. In some cases, the parties are able to negotiate a resolution early in the process, avoiding the need for a contested hearing. In others, multiple court appearances may be necessary before the matter is resolved.
It is important to recognize that the court's objective is not to reward one party or punish the other. Rather, the court seeks to ensure that any ongoing order continues to reflect the family's current circumstances and, where children are involved, serves their best interests.
When a Motion to Change involves child support or spousal support, updated financial disclosure is often one of the most important parts of the process. Income tax returns, notices of assessment, pay stubs, business records, and other financial documents may be required to give the court an accurate picture of each party's current financial circumstances.
Providing complete and accurate disclosure helps ensure that support decisions are based on reliable information. Failing to disclose relevant financial information can delay the court process and, in some cases, affect the outcome of the motion.
Not every disagreement requires a judge to resolve it.
In many family law matters, parents and former spouses are able to reach an agreement after discussing the changes that have occurred since the original order was made. As children grow older or financial circumstances evolve, both parties may recognize that updating an existing arrangement is in everyone's best interests. Resolving these issues cooperatively can often save considerable time, legal expense, and emotional stress.
Alternative dispute resolution methods such as negotiation and mediation may provide an opportunity to address changing circumstances without proceeding to a contested hearing. Even when a Motion to Change has already been started, settlement discussions frequently continue throughout the process. Reaching an agreement before a final hearing often allows the parties to maintain greater control over the outcome while avoiding the uncertainty of asking a judge to decide.
That said, informal agreements should be approached with caution. Verbal arrangements or casual exchanges through text messages and email will not adequately protect either party if disagreements arise later. Where parenting, support, or other ongoing legal obligations are involved, it is advisable to ensure that any new agreement is properly documented and, where appropriate, formalized through the court.
Although the concept of a Motion to Change may sound straightforward, these cases often involve complex legal and evidentiary issues. Before bringing a motion, it is important to determine whether the circumstances truly meet the legal threshold required by the court. Filing an application without sufficient grounds can result in unnecessary legal costs and delays, while waiting too long to address significant changes may create additional complications.
An experienced family lawyer can assess whether the facts are likely to constitute a material change in circumstances, explain the available legal options, and help develop an appropriate strategy based on the unique facts of the case. This often includes reviewing existing court orders, gathering financial disclosure, preparing court documents, negotiating with the other party, and presenting persuasive evidence if the matter proceeds before a judge.
Legal advice can also help identify situations where a Motion to Change may not be the most appropriate solution. In some circumstances, an appeal, a negotiated agreement, or another legal process may better address the issues involved. Understanding these distinctions early can help families make informed decisions while avoiding unnecessary litigation.
Family court orders are intended to provide stability, but they are not always meant to last forever. As families grow and circumstances evolve, orders involving parenting, child support, and spousal support may no longer reflect the realities of everyday life. Ontario's Motion to Change process recognizes that meaningful changes sometimes require existing court orders to be updated.
Successfully changing a family court order requires more than showing that life has become more difficult or inconvenient. The court must be satisfied that a genuine material change in circumstances has occurred since the original order was made and that modifying the order is justified under Ontario family law.

A material change is one that is significant, ongoing, and affects the basis upon which the original order was made. Examples may include a substantial change in income, a parent's relocation, a child's changing needs, or a significant change in parenting arrangements. Whether a particular change meets the legal test depends on the specific facts of the case.
Possibly. Child support is generally based on the paying parent's income, so a significant increase or decrease in earnings may justify reviewing the existing order. The court will consider the nature of the income change, supporting financial disclosure, and any other relevant circumstances before deciding whether the order should be varied.
Yes. Many parents are able to reach an agreement without asking a judge to decide the issue after a contested hearing. However, it is often advisable to have any new agreement properly documented to ensure it is legally enforceable and accurately reflects the parties' intentions.
Unlike an appeal, there is generally no fixed deadline for bringing a Motion to Change. However, delaying after a significant change in circumstances may complicate the case and, in some situations, affect the relief that may be available. Seeking legal advice promptly is recommended.
Although individuals may represent themselves in family court, Motions to Change involve procedural rules, legal tests, financial disclosure requirements, and evidentiary considerations. Working with an experienced family lawyer can help ensure the matter is properly prepared and presented.
