Custody Agreements in Ontario: A Real Talk Guide for Parents
When You Just Want What’s Best for Your Kids
There’s no manual for navigating a breakup or divorce—especially when kids are involved. One minute you’re juggling pick-ups and piano lessons as a family, and the next, you’re trying to figure out who gets what weekends.
Welcome to the world of custody agreements in Ontario. It’s not glamorous. It’s not easy. But it matters—deeply. Because at the end of the day (scratch that—every day), your child’s stability and emotional well-being are on the line.
Let’s strip away the courtroom lingo, get past the “legalese,” and talk like two people who just want kids to be okay. Sound good?
So… What Is a Custody Agreement?
In plain English? A custody agreement is a written plan that outlines how separated or divorced parents will care for and raise their child.
Legally, it’s more structured. It says:
- Who makes important decisions (like schooling, medical care, religion, etc.)
- When each parent spends time with the child
- How communication and responsibilities are handled
These agreements can be informal (a written understanding between you and your ex), or formalized into a court order. Some couples figure it out on their own. Others need lawyers or the court to step in.
What’s important is that the agreement reflects what’s best for the child—not just what’s easiest or “fair” for the adults.
Ontario Has Updated Language—Here’s What That Means
Thanks to updates to the federal Divorce Act and Ontario’s Children’s Law Reform Act, the language around custody has changed. These days, we talk about:
- Decision-making responsibility (instead of “custody”)
- Parenting time (instead of “access” or “visitation”)
Why the change? Because these terms reflect what’s really going on. It’s not about possession—it’s about responsibility, presence, and care.
Types of Custody (a.k.a. Decision-Making Responsibility)
Here’s how it generally breaks down in Ontario:
✅ Sole Decision-Making Responsibility
One parent has the exclusive right to make major decisions about the child’s life. Think: healthcare, education, extracurriculars, religion. The other parent may still have parenting time, but no say in those big-picture choices.
This is typically used in high-conflict situations, or when the other parent isn’t involved or available.
✅ Joint Decision-Making Responsibility
Both parents must agree on major decisions. It works best when communication is solid and mutual respect still exists (even if the relationship didn’t work out romantically).
✅ Split Responsibility
In rare cases—often when there’s more than one child—parents divide decision-making by child. For example: one child primarily with Parent A, another with Parent B.
✅ Shared Parenting Time (Not the Same as Shared Custody!)
This refers to time, not decision-making. If each parent has the child 40% of the time or more, it may be considered shared parenting time. This matters for emotional bonding and child support calculations.
Wait—What’s in a Custody Agreement Besides Decision-Making?
A well-made custody agreement covers more than just who makes decisions. It should include:
- A regular parenting schedule (weekdays, weekends, holidays, school breaks)
- Exchange details (who drops off/picks up, and when)
- Vacation and travel rules (especially for out-of-province or international trips)
- Communication expectations (with both the child and the other parent)
- Conflict resolution methods (mediation? renegotiation timelines?)
Think of it like a co-parenting manual. The clearer it is, the fewer fights you’ll have down the road.
What If You and Your Ex Agree on Everything?
First off—bravo. That’s no small feat.
If you’re aligned on parenting, you can draw up your own written custody agreement. But—and this is big—you should still get it reviewed by a family lawyer and possibly file it with the court. Why?
Because people change. Circumstances change. And if one parent later breaks the agreement? You’ll want the legal weight to enforce it.

What If You Can’t Agree? (Hint: You’re Not Alone)
Plenty of parents just can’t get on the same page. And that’s okay. There are still options before you head to court.
🔹 Mediation
You and your ex work with a neutral third party to create an agreement. It’s voluntary, confidential, and way less combative than a court case.
🔹 Arbitration
A private decision-maker (sort of like a judge, but less formal) hears both sides and makes a binding decision. This works well if you want a quicker result and more privacy than public court.
🔹 Collaborative Family Law
Each parent hires a specially trained lawyer, and everyone agrees not to go to court. You negotiate together in a structured process.
🔹 Going to Court
If nothing else works, court is an option—but it’s the most expensive, time-consuming, and emotionally taxing route. Courts will always put the child’s best interests first. But if you’re in a high-conflict situation, it may be the only safe or viable path.
The Best Interests of the Child: Always the Bottom Line
Let’s not lose sight of this.
In Ontario, the courts—and every decent lawyer or mediator—base all decisions on one question: What’s best for the child?
They’ll look at:
- The child’s relationship with each parent
- Stability of home environments
- Emotional, psychological, and physical needs
- The ability of each parent to provide love, guidance, and structure
- The child’s own views (if they’re old/mature enough to express them)
It’s not about punishing one parent or rewarding the other. It’s about building a healthy, supportive future for your kid.
Can a Custody Agreement Be Changed Later?
Absolutely. Life happens.
- Maybe you move.
- Maybe your job schedule shifts.
- Maybe your child’s needs change as they grow.
The good news? Custody agreements in Ontario can be updated—if both parents agree. If they don’t, you can ask the court to vary the agreement. You’ll have to prove that there’s been a material change in circumstances that affects the child’s well-being.
Just don’t go rogue. Making your own changes without agreement or court approval can land you in hot water.
What If One Parent Breaks the Agreement?
Let’s be honest—it happens.
One parent doesn’t show up for their parenting time. Or picks up the child on the wrong day. Or makes a major decision (like switching schools) without consulting the other parent.
When that happens, you’ve got options:
- Talk it out (if it’s safe and reasonable)
- Use mediation to resolve the conflict
- Document everything (texts, missed pick-ups, etc.)
- Apply to enforce the agreement through the court
If child support is also involved, the Family Responsibility Office can enforce payments by garnishing wages, suspending licenses, and more.
Tips to Make Shared Custody Actually Work
This isn’t legal advice—it’s parenting wisdom, gathered from real families who’ve been through it.
- Stick to the schedule. Kids crave predictability.
- Speak positively about the other parent. Your child is half them, after all.
- Use tech wisely. Shared calendars, co-parenting apps, even just clear texts help avoid confusion.
- Don’t compete. You’re not in a popularity contest.
- Check your ego. This is about your child’s peace of mind—not proving a point.
And when it gets tough? Remind yourself: “I’m doing this for them. Not for me.”
A Note on DIY Agreements (a gentle caution)
There’s something appealing about working it all out without the legal system involved. And sometimes it works beautifully. But without legal backing, even the most well-meaning agreement can fall apart.
If you’re going the DIY route, at least get a lawyer to review it. Or better yet, consider a flat-rate package to formalize it properly without blowing your savings.

This Isn’t Just Paperwork—It’s Their Childhood
Let’s bring it back to what really matters.
Custody agreements aren’t just about legal boxes or parenting “wins.” They’re about setting up a stable, loving, functional system that allows your child to thrive. Even if the grown-ups couldn’t make it work, your child can still grow up knowing they’re supported and cared for—every step of the way.
So take the time. Ask the hard questions. Get the help you need. And remember: it’s not about who’s right. It’s about what’s right for your child.
