Can your ex move away with your kids in Ontario?

Whether your ex can move away with your kids in Ontario depends on whether the move is a "relocation" and whether it is in your children's best interests — not on what is easier for her. If a parenting order is in place, she has to give you 60 days' written notice before moving the children, and you have 30 days to object in writing. The court then decides, weighing the reasons for the move, the role you play in your children's lives, and the impact on your relationship with them. By the end of this article you will know what counts as a relocation, what the notice rules are, and the exact step to take if you object.

A father who has just learned his children might be moved hours away is rarely worried about the law in the abstract. The fear is concrete and specific: fewer bedtimes, missed hockey practices, a two-hour drive that turns every other weekend into a logistics problem. The law does not ignore that fear. It is built around it.

This article is information, not legal advice. It explains how relocation works in Ontario so you can have a grounded conversation about your own situation.

What counts as a "relocation" versus an ordinary move?

Not every move triggers the relocation rules. The law draws a line between a routine change of address and a relocation — and the difference decides which process applies.

A change of residence is a move that does not have a significant impact on your children's relationship with you. A parent who moves across town, or to the next suburb, has changed residence. The school run still works. Your parenting time still happens on the same schedule. The move is real, but it does not break the arrangement.

A relocation is a move that will have a significant impact on your children's relationship with you or another person who has parenting time. A move from Toronto to Thunder Bay is a relocation. So is a move that, on paper, looks shorter but still makes the existing parenting schedule unworkable — a two-hour drive each way can do that as surely as a flight across the country.

The test is impact, not distance. The Department of Justice fact sheet on moving after separation or divorce is direct about this: even a short move can be a relocation if it considerably affects the parenting schedule. That is the question a court asks first — does this move break the arrangement your children rely on?

This matters because the two situations carry different obligations. A relocation triggers formal notice and an objection window. A simple change of residence carries a lighter notice duty and cannot be objected to in the same way. If you are unsure which one you are facing, map it against your current schedule before anything else — see how parenting time and decision-making actually work in Ontario so you know exactly what the move would disrupt.

What are the notice rules — the 60 days and the 30 days?

If there is a parenting order or agreement in place, the other parent has to give you written notice before relocating. This is not a courtesy. It is a legal requirement under the Divorce Act — the federal law that applies if you were married — and under Ontario's Children's Law Reform Act, which applies if you were not. Both were brought into line with each other in 2021, so the relocation rules are now broadly the same whether or not you were married.

The notice rules break down into two numbers you need to hold onto.

60 days' written notice. A parent planning to relocate with the children must give you at least 60 days' written notice before the move. Section 16.9 of the Divorce Act sets this out. The notice has to be in writing and has to include the expected date of the move, the new address and contact details, and a proposal for how parenting time would work after the move.

30 days to object. Once you receive a proper notice, you have 30 days to object in writing. Your objection has to say that you disagree with the move and set out why — your role in the children's lives, the impact on your relationship, and your view on the proposed new schedule.

If you object within that window, the relocating parent cannot simply move the children. The disagreement goes to the court, which decides whether the relocation can go ahead. If you do not object within 30 days, and there is no other court order stopping the move, the relocation can proceed. The clock is real. Missing it weakens your position, so the date you receive the notice is a date to write down.

How does the court decide — and what is the Barendregt approach?

When you and the other parent disagree about a relocation, the court decides one question: is the move in the children's best interests? There is no presumption either way. The court does not start from the position that the children should move, and it does not start from the position that they should stay. It looks at the specific family in front of it.

The leading case is Barendregt v. Grebliunas, 2022 SCC 22, a Supreme Court of Canada decision that governs relocation across the country, including Ontario. It confirms that the analysis is highly fact-specific and centres on the child's physical, emotional, and psychological wellbeing. The Supreme Court's plain-language summary of the case is worth reading in full.

Three factors carry real weight:

• The reasons for the move. A move for a genuine reason — a job, family support, a safer living situation — lands differently than a move that looks designed to cut you out. The court can and does examine the purpose behind the relocation.
• Each parent's role. The court looks at how involved you actually are. The father who does pickups, helps with homework, and shows up to appointments stands on different ground than one who sees the children occasionally. This is where your day-to-day involvement becomes evidence.
• The impact on the child's relationship with you. The court weighs what the move would do to your bond with your children and whether a new schedule could realistically preserve it.

Barendregt also changed how courts ask one specific question. Judges are no longer allowed to put the relocating parent in a "double-bind" — they cannot ask whether she would still move if the children had to stay behind. That question used to trap the moving parent and skew the analysis, and the Supreme Court removed it. The focus stays where it belongs: on the children, not on testing the adults.

A move that alters the schedule is itself a material change in circumstances. So if you already have a parenting order, the relocation request runs alongside the rules for changing a parenting order in Ontario.

What can you do if you object to the move?

You have more options than waiting and hoping. If you receive a notice of relocation and you disagree, there is a defined path.

First, object in writing within the 30-day window. State plainly that you do not agree to the move and give your reasons. Keep a copy and proof of when you sent it. This written objection is the step that stops an automatic relocation and moves the decision to the court.

Second, try to resolve it directly or through mediation before it becomes a court fight. Sometimes a relocation dispute is really a schedule dispute — the other parent has a genuine reason to move, and the real question is how your time gets protected afterward. A revised parenting plan that builds in longer blocks, more video contact, and a clear travel arrangement can address the move without litigation. Working this out by agreement is faster, cheaper, and easier on the children.

Third, if agreement is not possible, the matter goes before a judge. Either parent can bring it to court, and the court can allow the move, prohibit it, or allow it on conditions — for example, a changed schedule or a requirement that the moving parent cover travel costs. Understanding how the family court process works in Ontario helps you see what that path looks like before you commit to it.

Build your case around your role, not your anger. The court responds to evidence of an involved father and the concrete harm the move would do to that relationship. A calm, specific record of your involvement is worth more than any argument about fairness.

What happens if there is no existing order?

This is where many fathers are caught off guard. If there is no court order and no written agreement about parenting, the formal 60-day notice rule under the Divorce Act does not automatically apply, and a parent may have more room to move with the children.

That does not mean she can move them anywhere with no consequence. Steps to Justice is clear that you can usually move a child without permission only if the move is not likely to have a big impact on the child's relationship with the other parent. A move that would significantly disrupt your relationship still puts the question of the children's best interests in play — and you can ask a court to weigh in.

The practical lesson is that the absence of an order cuts both ways. It gives a moving parent more freedom in the short term, and it gives you a reason to act quickly rather than assume nothing can be done. If you have no order, getting an interim parenting arrangement in place — by agreement or through the court — is what creates the notice protection you would otherwise lack. The sooner there is a defined schedule on paper, the harder it is for the children to be moved without the process that protects your relationship with them.

The one thing to do this week

Write down the date. If you have received a notice of relocation, note the exact day it arrived and count 30 days forward — that is your objection deadline, and it does not move. If you have not received notice but you are worried a move is coming, write down what your parenting schedule looks like now and how a move would change it. Either way, that single page — dates, your involvement, what stands to be lost — is the foundation of everything that follows.
