Here is the situation a lot of Ontario parents find themselves in a year or two after a separation is finalized. The parenting arrangement that both sides agreed to, or that a judge ordered, made complete sense at the time. But life moved on. Someone got a new job with different hours. A child hit a certain age and started having real opinions about where they want to spend their weekdays. One parent remarried, moved to a new city, or the original parenting schedule just stopped working for reasons nobody could have fully predicted when the order was made.
And now you are wondering whether you can actually change things or whether you are stuck with an order that no longer fits your family.
Changing a parenting order in Ontario is possible. But it is not as simple as both parents deciding something new makes more sense and moving on. There is a court process with specific requirements, a legal threshold you have to clear, and formal steps that protect the outcome once you get there. Understanding those steps from the beginning saves real time, money, and frustration later.
What Is a Parenting Order and Can It Be Changed?
A parenting order is a legally binding court order that sets out how parents share time with and make decisions for their children after separation. In Ontario, parenting orders can be varied through either a formal court application or a consent agreement between both parents, but only when specific conditions are met.
Parenting orders in Ontario are made under one of two pieces of legislation. The federal Divorce Act applies to married couples who have divorced. Ontario’s Children’s Law Reform Act governs unmarried parents and situations falling outside the Divorce Act. The 2021 amendments to the Divorce Act replaced “custody” and “access” with “parenting time” and “decision-making responsibility,” reflecting a shift in how Canadian family law describes parenting arrangements. Existing custody and access orders made before 2021 remain valid, but any new orders or variations use the updated terminology.
The governing principle behind any parenting order, whether original or varied, is the best interests of the child. Courts do not look at what is most convenient for either parent. They look at what arrangement genuinely serves the child’s needs, stability, and well-being.
Does an Informal Change to the Parenting Schedule Actually Hold Up?
No. An informal change to a parenting arrangement, even one both parents have been following for months, is not legally enforceable.
This trips up a lot of separated parents in good faith. A lot of families drift away from the terms of their existing parenting order over time. The schedule shifts informally. One party starts picking up the kids on a different night. Both sides seem fine with it. Nobody has any reason to go to court. Why would they?
Until a disagreement surfaces. Because when that happens, what family court cares about is the agreement or court order that is on file, not the informal arrangement the two of you had been running. If one parent decides to snap back to what the original order says, there is very little the other parent can do to stop them if nothing was ever formally changed.
A parenting order is a court order. It does not stop being enforceable just because neither party has been following it strictly. If you want the existing parenting arrangement to change in a way that is actually protected, you need to either get the change approved through the formal court process or reach an agreement through proper legal channels. An informal understanding, however reasonable it feels at the time, gives neither parent any real security when things get difficult.
What Courts Need to See Before Changing a Parenting Order in Ontario
Courts do not vary a parenting order simply because one parent wants a different arrangement. There is a specific legal threshold that must be cleared first, and it is deliberately set to protect children’s stability.
The Supreme Court of Canada established the governing test in Gordon v. Goertz [1996] 2 SCR 27, which remains the standard across Canada. Under Section 17(5) of the Divorce Act, and the equivalent provision in Section 29 of Ontario’s Children’s Law Reform Act, the threshold is called a material change in circumstances.
The three-part test requires:
- A genuine change in the condition, means, needs, or circumstances of the child or in the ability of one of the parents to meet those needs
- That the change was not foreseen and could not reasonably have been anticipated when the original order was made
- If the change is established, the court then asks what new arrangement is in the best interests of the child
Those are two separate inquiries, and courts do not skip the first to get to the second. Establishing a material change in circumstances is a threshold question. Only after it is satisfied does the best interests analysis begin.
This approach exists because the whole point of a parenting order is to give children stability. If any parent who wanted a different arrangement could walk into family court without showing something had genuinely changed, existing orders would mean very little and children would be pulled through relitigation repeatedly. The threshold filters out the cases where nothing real has shifted while keeping the door open for parents whose situations have genuinely changed.
What Actually Qualifies as a Material Change in Circumstances?
A material change is one that is real, significant, and was not reasonably foreseeable when the original order was made. Not every development in a family’s life meets that bar.
Changes that courts in Ontario have recognized as material include:
- Relocation of a parent to another city, region, or province, particularly where the move significantly affects parenting time or the child’s established routine
- A meaningful shift in one parent’s work schedule that makes the existing parenting order genuinely unworkable on a sustained basis
- Serious health issues affecting either a parent or the child’s needs in ways the original arrangement cannot accommodate
- Safety concerns including evidence of family violence, substance abuse, or neglect that were not present or not known when the original order was made
- One parent consistently and deliberately failing to follow the parenting order over time, which can itself constitute a significant change
- A child’s clearly expressed and consistent views as they mature, particularly when those views are genuine and have not been influenced by one parent
What generally does not qualify: preferring a different schedule without a substantive reason, predictable changes that were foreseeable at the time of the original order, or minor disruptions that families navigate through communication rather than court. Courts are also careful about whether the change relied on was already contemplated in the original order. If the original order was made knowing a parent might relocate, a later relocation may not satisfy the threshold.
One thing worth being honest about before filing anything: some parents arrive with strong conviction that they have a clear material change argument, and the actual facts are closer to inconvenience than genuine change in the circumstances of the child. A family law lawyer will tell you plainly which one you are looking at before you spend time and money on an application that may not survive the threshold stage.
How Do You File a Motion to Change a Parenting Order in Ontario?
Once there is a genuine material change in circumstances to point to, the formal step for changing a parenting order in Ontario is making a motion to change. The process unfolds as follows.
The primary form is a Motion to Change, Form 15, filed with the Ontario family court that made the original parenting order. This is important: you file at the original court, not at whichever courthouse is most convenient based on where you live now. Along with the motion, you file a supporting affidavit setting out the material change in circumstances and explaining the new arrangement you are asking for and why it reflects the best interests of the child.
A few practical points worth knowing before you start:
- If you are also seeking a change in child support alongside the parenting variation, you will need to file a Financial Statement, Form 13, as well. Parenting time directly affects how child support is calculated under the Federal Child Support Guidelines, so courts typically address both at once rather than in separate proceedings.
- The other parent must be served with the motion and has the right to file a responding affidavit
- Most contested motions go through a case conference before any formal hearing, where a judge helps both sides identify what is genuinely in dispute and whether anything can be resolved without a full argument
- If the matter remains contested after the case conference, it proceeds to a hearing at the Superior Court of Justice where a judge decides whether the threshold is met and, if so, what the new parenting order should say
Timelines vary. Some files resolve quickly through negotiation after the motion is filed. Others take many months before a hearing date is reached. During the entire period, the existing parenting order remains in force. One principle that family law professionals flag consistently: filing a variation application does not suspend the original order while the case is pending. Both parents are expected to follow the existing order until a new one is made. Unilaterally deviating from the order while the case is in progress creates problems for the parent who does it, regardless of how understandable their reasons seem.

The Ministry of the Attorney General also provides justice services and free information about family law matters through community legal education resources for parents who are seeking general guidance before retaining a family lawyer.
When Both Parents Agree to the Change
When both parents agree on the variation, the process is considerably faster and far less adversarial than contested litigation.
An agreed change can be documented through a consent motion to change, which is a joint request to the court asking it to replace the existing order with new terms both parents have accepted. Courts still review the proposed change to confirm it serves the best interests of the child. A judge will not approve something that raises genuine concerns about a child’s safety or wellbeing just because both parents signed off on it. But where the agreed change is reasonable and genuinely child-focused, consent motions move through the system quickly.
Mediation is another path worth knowing about. A neutral third party helps both parents work through the issues and reach a parenting arrangement they can both live with. If mediation produces an agreement, it can be filed with the family court and converted into an enforceable parenting order. The court will consider the agreement and, assuming it reflects the child’s best interests, approve it.
Even when both parents are cooperative, going through the formal process is worth doing. An informal agreement provides no legal protection if the relationship between the parents deteriorates later. A court-approved variation order does.
Whether you reach an agreement through mediation or direct negotiation, getting legal advice before finalizing anything matters. Ontario’s family law has specific requirements around what parenting agreements need to address. A family law lawyer can review the terms before anything is filed and flag anything that could create problems once the order is in place.
What Happens If the Situation Is Urgently Wrong?
Most variation applications take months to move through the regular court process. That is the reality of family justice in Ontario. But some situations genuinely cannot wait, and where a child faces an immediate risk of harm, a parent can bring an emergency motion requesting urgent temporary relief.
Courts treat emergency motions seriously and scrutinize them carefully, because they are sometimes filed as a tactical first move in a parenting dispute rather than a genuine response to an urgent child safety concern. Judges are not naive about this, and they look closely at whether the circumstances actually meet the threshold for emergency relief.
To succeed, the moving parent needs to demonstrate that the child faces a real and immediate risk, that the situation cannot be managed by following the existing parenting order while waiting for a regular hearing, and that the temporary change requested is necessary and proportionate. Specific, documented evidence of the risk makes a meaningful difference. General concerns without concrete evidence rarely succeed on an emergency basis.
If an emergency motion is granted, it produces a temporary parenting order that stays in place until the matter can be heard properly at a full hearing. That full hearing is where both parties present their complete evidence and the court makes a final determination on the parenting arrangement.
Frequently Asked Questions About Changing a Parenting Order in Ontario
How long does it take to change a parenting order in Ontario?
An agreed or consent variation can often be finalized within a few weeks to a couple of months, depending on court scheduling. A contested variation application typically takes between six months and well over a year. In complex matters that proceed to trial, the timeline can be longer.
What is the legal test for changing a parenting order?
The governing test comes from Gordon v. Goertz [1996] 2 SCR 27. A parent must first establish a material change in circumstances since the original order was made, meaning a genuine change in the child’s needs or a parent’s ability to meet them that was not reasonably foreseeable when the order was issued. Once that threshold is met, the court conducts a full best interests of the child analysis to determine what the new arrangement should be.
Can I change a parenting order without going to court?
Yes, if both parents agree. A consent motion to change documents the new arrangement and converts it into an enforceable order through the court without a contested hearing. Even agreed changes should be formally filed with the court rather than left as an informal understanding, because informal arrangements are not legally enforceable if one parent later reverts to the original order.
Can a child decide which parent to live with in Ontario?
A child’s views and preferences are one factor courts consider, but they are not determinative on their own. The weight given to a child’s preferences depends on their age, maturity, and the genuineness and consistency of those views. There is no fixed age in Ontario at which a child’s choice is automatically followed.
What qualifies as a material change in circumstances in Ontario?
Material changes recognized by Ontario courts include parental relocation, a significant shift in a parent’s work schedule, documented safety concerns such as family violence or substance abuse, one parent consistently failing to follow the existing parenting order, and a child’s own clearly expressed and consistent preferences as they mature. Predictable changes or general dissatisfaction with the arrangement typically do not qualify.
What happens if one parent wants to move to another city?
Relocation is one of the most common grounds for a variation application. Under the 2021 Divorce Act amendments, a parent who plans to relocate must provide at least 60 days’ notice to the other parent. If the parents cannot agree on how the relocation affects parenting time, a court decides based on the best interests of the child.
Does a parenting order automatically end when a child reaches a certain age?
No. A parenting order remains in effect until it is formally varied by agreement or court order, or until the child is no longer subject to parenting orders under applicable legislation. A child’s changing needs and preferences as they age can support a variation application but do not automatically alter the existing order.
