In Canada, courts do not award full custody of a child simply because one parent asks for it. They look at evidence of family violence, neglect, serious parenting concerns, chronic conflict, and each parent’s ability to provide a safe, stable environment.
In this guide, we explain:
- The main grounds courts consider
- The evidence that can support a sole decision-making application
- How the court process works when parents cannot agree
Full Child Custody Under Canadian Law
“Full custody” is not a legal term in Canada. Parliament removed the word from the Divorce Act in 2021.
The new term is sole decision-making responsibility: one parent holds the authority to decide the child’s health care, schooling, religion, and travel. The other parent usually keeps parenting time anyway. Courts treat those two things as separate orders, which surprises most people who call our office.
Sole Decision-Making Responsibility vs. Parenting Time
Sole decision-making responsibility answers who decides. Parenting time answers when the child is with each parent. A judge can grant one parent every major decision and still order a generous schedule for the other, including supervised parenting time where safety requires it.
| Aspect | Full Custody / Sole Decision-Making Responsibility | Parenting Time |
|---|---|---|
| Core Idea | Who makes major life decisions for the child. | When and how a child spends time with each parent. |
| Legal Focus | Decision-making authority, not where the child sleeps. | Care and scheduling, including daily time, routines, and exchanges. |
| Typical Decisions | Education, medical care, religion, travel, and passports. | Bedtime, meals, transportation, and activities during that parent’s time. |
| Possible Setups | Sole decision-making (one parent decides) or joint decision-making (parents decide together). | Equal or shared time, primary residence, supervised time, or limited contact. |
| Change Triggers | Inability to cooperate, safety risks, or the history of care. | The child’s age and needs, logistics, school, and community stability. |

Three Grounds Accepted by Courts for Sole Decision-Making
No checklist guarantees a custody decision. Ontario judges award sole decision-making when the record shows that joint decision-making would fail the child. Three fact patterns carry the most weight, and getting sole custody in Ottawa almost always rests on one of them.
1. Family Violence, Abuse and Coercive Control
Family violence is the strongest ground available. The Divorce Act defines it broadly enough to capture physical abuse, sexual abuse, emotional abuse, and coercive control, which means a pattern of intimidation that never leaves a bruise. A judge weighs the violence itself and its effect on the parent’s capacity to cooperate. Documented domestic violence frequently ends any realistic argument for joint decision-making.
If you or the child face immediate danger, a restraining order in Ontario moves faster than a custody application.
2. Neglect, Substance Abuse and Untreated Mental Health
Neglect means the basics went unmet: supervision, meals, medical appointments, school attendance. Substance abuse counts when it impairs parenting, not because a parent drinks. The same test applies to mental health. A diagnosis proves nothing on its own; untreated illness that destabilises the home does. Abandonment, where a parent drops out of the child’s life for months, supports an unfit parent argument on its own.
3. Parental Alienation and Unworkable Co-Parenting
Parental alienation describes one parent systematically turning a child against the other. Courts take it seriously and sometimes respond by moving decision-making rather than restricting contact. Chronic failure of communication also qualifies. Where co-parenting has collapsed into daily conflict, joint decision-making stops functioning, and a high-conflict separation becomes its own ground.
The Best Interests of the Child Test Decides Custody
Every custody decision in Ontario runs through one test. The Children’s Law Reform Act and the federal Divorce Act both direct judges to the best interests of the child, and nothing else. Not fairness between parents. Not who filed first.
The Statutory Factors Judges Weigh
The statutes list the factors a judge must consider:
- Family violence and its impact on the child and other family members
- Each parent’s ability to meet the developmental needs of the child, including health, schooling, and routines
- The history of care, meaning who has acted as primary caregiver
- The child’s views, sometimes captured formally in a Voice of the Child Report
- Stability at home, at school, and in the community
- Any civil or criminal proceeding touching safety
Why the Status Quo and History of Care Matter
Judges dislike disruption. The status quo carries real weight, because a child already settled in a school and a home environment has something to lose. That favours whichever parent has functioned as primary caretaker, handled appointments, and kept the routine intact.
Parental capacity gets assessed on the record, not on assertion. A parent who can show two years of school pickups has a stronger case than one who describes their own devotion.

Evidence Supports a Full Custody Application
A custody application succeeds or fails on documents. Ontario courts apply the balance of probabilities, a lower burden of proof than criminal law, but they still need something more than one parent’s account.
Records, Reports and Disclosure That Carry Weight
The material that moves judges tends to be third-party:
- Police record checks, occurrence reports, and safety plans
- Medical records and school records showing involvement or absence
- Children’s Aid Society files and letters
- Messages and calendars establishing a pattern of missed visits
- A financial statement, plus any expert assessment the court orders
An affidavit tells your story. Records prove it. A social worker’s report or a psychological assessment can settle a disputed fact that no amount of argument would.
What a Voice of the Child Report Adds
The Office of the Children’s Lawyer can be appointed to prepare a Voice of the Child Report, which puts the child’s preference before the judge without dragging the child into the courtroom. Weight rises with age and maturity.
It is one factor, never the deciding one, and no parent should treat it as a verdict.
The Ontario Family Court Process for a Parenting Order
Parenting cases run in the Ontario Court of Justice or the Superior Court of Justice. Divorce claims must go to the Superior Court. A parenting order alone can go to either, depending on whether your area has a unified family court.
From Application to Case Conference and Motions
You start by filing an application for decision-making responsibility, parenting time, and often child support. Form 35.1, the affidavit in support of a parenting claim, gets sworn and filed with it. Both parents then complete the Mandatory Information Program.
The first appearance is a case conference. No judge decides anything final there. If something cannot wait (such as school registration or supervised parenting time), you bring a motion for an interim order, and that court order governs until the case resolves. Everything filed goes into the continuing record.
Settlement, Minutes of Settlement and Trial
Most families never reach trial. Negotiation, mediation, or a settlement conference usually produces minutes of settlement and a final order. Reaching a custody agreement without court is faster and cheaper than litigating, and family mediation works even in tense files. Trial remains available when safety demands it.

Full Custody in Canada: Frequently Asked Questions
Is joint custody the default in Ontario?
No. Ontario has no automatic joint custody presumption. A judge assesses each case under the Divorce Act and the Children’s Law Reform Act, prioritising safety and the child’s best interests.
Where conflict runs high, or the home is unsafe, sole custody may be appropriate.
Do I need proof to get sole custody?
Yes, and credible proof. Gather court documents, messages, police notes, school updates, and any report already prepared. A judge may order supervised parenting time where risk exists, or preserve the status quo to protect the child.
Can a father get full custody in Canada?
Yes. Canadian law contains no maternal preference, and fathers receive custody of a child regularly. What decides it is the record: caregiving history, stability, and whether the other parent’s conduct puts the child at risk.
Can I relocate with the child after getting full custody?
Relocation triggers strict notice requirements and a fresh best-interests analysis, even for a parent with sole decision-making. Moving with children requires the judge to weigh schooling, support networks, and the other parent’s schedule.
International moves may engage the Hague Convention.
Does full custody end the other parent’s child support?
No. Decision-making and money are separate questions in Canadian law. A non-custodial parent still pays under the guidelines, and the amount tracks income and parenting time, not who holds authority.
