Child Custody in Ontario (2026): How It's Really Decided

This article explains how child custody works in Ontario as of 2026 and is general information, not legal advice. The terms, the test, and the factors come from the Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), the Children's Law Reform Act, R.S.O. 1990, c. C.12, and the Department of Justice. Every family is different, and a family lawyer can advise on your own situation.

Child custody Ontario parents search for still uses a word the law quietly retired. Since March 2021, Ontario courts no longer decide "custody" or "access" at all. What most people call a custody fight is now two separate legal questions, decided on one test: the best interests of the child. Understanding that split is the difference between arguing over a label and actually sorting out how your family will work. If you would rather have someone assess your situation first, our guide to the family situations a lawyer handles is a good place to start.

This guide takes the modern law apart in plain language: the terms that replaced custody and access, the two questions a court actually answers, the best-interests factors that drive every decision, what real arrangements look like across Canada, and how parents settle all of it, usually without a trial.

Child custody Ontario: the quick answer

Here is the compressed version of how child custody Ontario cases are decided today, unpacked in full below.

• "Custody" is gone from the law. Since 2021 the legal terms are decision-making responsibility, parenting time, and contact. Old orders using "custody" and "access" are still valid.
• It is really two questions. Who makes the major decisions (decision-making responsibility), and when the child is in each parent's care (parenting time). They are decided separately.
• One test governs both. A court considers only the best interests of the child, giving primary weight to the child's safety, security and well-being.
• No preferred parent. Ontario law has no preference for mothers or fathers, and no fixed formula or points score.
• Most families never see a judge. A parenting plan agreed between parents, often with a mediator, settles the vast majority of cases out of court.
• A child does not simply choose. The child's views count, weighed by age and maturity, but there is no magic age at which a child decides.

The word that no longer exists

The single biggest change is linguistic, and it is deliberate. In March 2021, amendments to the federal Divorce Act and Ontario's Children's Law Reform Act removed "custody" and "access" and replaced them with plainer, less combative terms.

The old words framed parenting as a prize one parent won and the other visited. The new language describes responsibilities and time instead. Three terms do the work now, set out in the Department of Justice's overview of the changes to the Divorce Act:

• Decision-making responsibility replaces custody. It is the authority to make significant decisions about a child's health, education, religion, language, and major activities.
• Parenting time replaces access. It is the time a child spends in the care of each parent, and the parent with the child during that time makes the everyday decisions.
• Contact is a newer, narrower idea: time a court can order between the child and someone who is not a parent, most often a grandparent.

The shift matters beyond vocabulary. An agreement or order made before March 1, 2021 using "custody" and "access" remains fully valid, and nobody has to return to court just to relabel it. But any new case, and the way lawyers and judges now talk, runs on the modern terms. Ontario's family law reforms arrived through the Moving Ontario Family Law Forward Act, which lined the province's Children's Law Reform Act up with the federal changes so married and unmarried parents are treated consistently.

Question one: who makes the big decisions

Decision-making responsibility answers who has the authority to make the major, long-term choices in a child's life: schooling, medical care, religion, and significant extracurriculars. It can be held by one parent alone or shared between both.

Sole decision-making responsibility gives one parent the final say on those major questions. Joint decision-making responsibility means both parents make them together, which works well when communication is functional and poorly when it is not. Courts can also divide it by subject, giving one parent authority over education and another over health, though a clean split is less common. Whichever applies, the parent caring for the child at a given moment still makes the ordinary daily calls, meals, bedtime, screen time, without needing to consult the other.

The two questions of child custody Ontario law now separates are easy to mix up, so it helps to see them side by side.

A worked example makes the distinction concrete. Consider two parents in Mississauga who communicate well about their daughter but live far enough apart that she is based mainly with her mother during the school week. They might agree to joint decision-making responsibility, because they can cooperate on school and medical choices, while parenting time is weighted toward one home for stability. Decision-making and living arrangements are set independently, which is exactly why treating "custody" as one all-or-nothing prize misreads how the modern system works.

Question two: where the child actually lives

Parenting time is the schedule: which nights the child is in which home, how holidays split, how pickups and drop-offs happen. It runs on a spectrum from mostly one home to a roughly even split, and it is decided separately from who holds decision-making responsibility.

Most arrangements fall into a few recognizable shapes. The table below sets out the common ones without pretending any is a default; the right pattern is the one that fits the particular child.

Schedules are usually recorded in a parenting plan, the practical document that turns a general agreement into specific weekdays, weekends, holidays, and travel rules. Ontario also expects a parent who wants to relocate with a child, a move that would affect the other parent's time, to give formal notice, generally 60 days, so the change can be worked out or brought to a court before it happens rather than after. Many separating couples set the whole schedule inside a separation agreement in Ontario, which records parenting, support, and property in one enforceable contract.

The one test behind every decision: the best interests of the child

There is only one test. A court making a parenting order considers only the best interests of the child, and it gives primary consideration to the child's physical, emotional and psychological safety, security and well-being. Everything else feeds into that.

This is not a vague slogan. Both the Divorce Act (section 16) and Ontario's Children's Law Reform Act (section 24) set out a specific list of factors a court must weigh, and family violence carries its own detailed sub-list. The factors are considered together for the individual child, not scored or ranked, which is why two families with similar facts can land in different places. The same Act carries a provision parents rarely hear about: under s. 61, a parent with decision-making responsibility can appoint a guardian by will, but the appointment lapses after 90 days unless that person applies to the court, one of the precedence rules covered in estate planning in Ontario. The explorer below lays the statutory factors out; open any one to see what it means in practice.

Two points cut through a lot of myths. First, there is genuinely no preference for mothers or fathers in the law; the "history of care" factor simply tends to reflect who was doing the daily caregiving before the split. Second, a willingness to support the child's relationship with the other parent is weighed heavily: a parent who keeps the other involved is viewed very differently from one who tries to cut them out. For the deeper background on how these pieces fit across the country, the Department of Justice's parenting arrangements resource is the neutral national source, and Ontario's own parenting and custody guidance covers the provincial process.

What the numbers say about real arrangements

Across Canada, most children of separated parents have lived primarily with one parent, but roughly equal shared parenting is climbing fast. National survey data gives a sense of what real outcomes, as opposed to the law on paper, actually look like.

These figures describe outcomes, not entitlements. They reflect caregiving history, geography, work schedules, and above all what parents agreed, rather than any thumb on the scale in the statute. The clear trend toward shared time tracks the 2021 reforms, which framed parenting time around the principle that a child should have as much time with each parent as is consistent with the child's best interests. Across the thousands of family requests we see at Olanur, parents increasingly arrive already expecting to share time, and asking how to make a two-home schedule work rather than who "wins."

How a custody agreement actually gets made

Most parenting arrangements are settled by agreement, not by a judge. Going to court is generally a last resort, used when parents cannot agree or when safety is at stake, and even many filed cases resolve on consent before trial.

There is a rough ladder of routes, from cheapest and calmest to slowest and most expensive. Parents can write their own parenting plan, sometimes using free templates and always ideally with each side getting independent legal advice before signing. They can also use a mediator, a neutral professional who helps them build the plan; Ontario subsidizes family mediation connected to its family courts, with on-site sessions free and off-site mediation charged on a sliding scale by income.

If agreement proves impossible, one parent applies to the Ontario Superior Court of Justice or the Family Court, files a parenting affidavit setting out the proposed plan, and a judge decides using the best-interests test. A custody agreement built carefully once, whether at the kitchen table or through mediation, tends to hold far better than terms imposed after a fight, and it keeps the decisions about the child with the people who know the child best.

What it costs, and the Ontario specifics

Cost is driven almost entirely by one choice: agree or litigate. A parenting plan reached directly or through mediation can cost very little, while a contested court battle is where the real money goes.

Rough, typical 2026 ranges tell the story. Independent legal advice on a parenting plan often runs around $1,500 per person, a one-hour consultation to understand your position commonly costs $300 to $500, subsidized on-site court mediation can be free, and a genuinely contested parenting trial can climb into five figures once you add court time and preparation. Those are typical market figures, not quotes; the deciding variable is conflict, not the province.

On the process side, Ontario runs parenting cases through the Superior Court of Justice, the Family Court branch, or the Ontario Court of Justice depending on where you live, and the same best-interests test applies in each.

When it's worth talking to a lawyer

Some parenting situations are safe to handle with a well-drafted plan and a review; others call for advice early. Reaching for a family lawyer tends to pay off when:

• There is any safety concern. Family violence, threats, or a child's exposure to conflict change everything, and courts can act quickly on supervised parenting time or emergency orders.
• The other parent already has a lawyer. A parenting plan negotiated on even footing protects you from agreeing to terms you did not fully understand.
• Relocation is on the table. A proposed move that would reshape the schedule is one of the most contested issues in family law, and the notice rules and timing matter.
• Communication has broken down. When parents cannot cooperate, options like parallel parenting or sole decision-making need careful framing.
• You are unsure of your position. A single paid consultation can tell you whether what you are about to sign is fair before it becomes hard to undo.

Frequently asked questions

Where to start this week

The most useful first move is often the smallest one: write down the parenting schedule and the major decisions as you would want them to work, then get that plan reviewed before anything is signed or filed. Child custody Ontario disputes rarely turn on the label; they turn on the details of the plan and whether it genuinely fits the child. Get those right, keep the tone cooperative where you can, and most families never need a courtroom at all.

If you would rather have a family lawyer review your parenting plan, advise on decision-making and parenting time, or step in where safety or relocation is at stake, Olanur can match you with a verified Ontario family lawyer, free and with no pressure.
