When parents separate or divorce, one of the most emotional and important issues they face is child custody. Many parents worry about where their child will live, who will make decisions for them, and how parenting time will be shared. Understanding how child custody is decided in Ontario can help parents feel more prepared and make informed decisions during a difficult time.
Ontario family courts focus on one primary goal when deciding custody matters: the best interests of the child. Every custody decision is guided by this principle, regardless of the parents’ disagreements or personal circumstances.
In Ontario, child custody refers to the legal authority to make important decisions about a child’s life. These decisions typically involve education, healthcare, religion, and general well-being. Custody is different from access, which refers to parenting time or visitation.

Custody can be shared between parents or awarded to one parent, depending on the situation and what arrangement best supports the child’s needs.

Ontario courts do not automatically favor one parent over the other. Instead, judges carefully evaluate what arrangement will best support the child’s physical, emotional, and psychological well-being.
Factors that courts consider when determining the best interests of the child include:
Courts aim to minimize disruption in the child’s life while ensuring safety, consistency, and emotional security.
There are several types of child custody arrangements recognized under Ontario law. The court will determine which option works best based on the family’s circumstances.
Sole custody means one parent has the authority to make major decisions for the child. The other parent usually still has access unless it would not be in the child’s best interests.
Joint custody means both parents share decision-making responsibility. This requires strong communication and cooperation between parents.
Shared custody typically involves the child spending at least 40% of their time with each parent. This arrangement often supports active involvement from both parents.

Parenting time, also known as access, refers to the amount of time a child spends with each parent. Ontario courts recognize that children benefit from meaningful relationships with both parents whenever possible.
When determining parenting time, courts consider:
The goal is to create a schedule that supports stability while allowing both parents to remain actively involved in the child’s life.
Parents are often surprised to learn that Ontario courts are not interested in past relationship conflicts unless they directly affect the child. Judges focus on each parent’s ability to act in the child’s best interests moving forward.
However, certain behaviors can negatively impact custody decisions, including:
Courts expect parents to encourage a healthy relationship between the child and the other parent, even after separation.
A child’s wishes may be considered, especially as they grow older and become more mature. While younger children may not have their preferences weighed heavily, teenagers often have more influence in custody decisions.
Courts may gather a child’s views through:
Ultimately, the child’s preferences are just one factor and are considered alongside the overall best interests standard.
Not all custody disputes need to be resolved in court. Many parents reach agreements through negotiation, mediation, or collaborative family law. These options can be less stressful, faster, and more cost-effective.
Parents who can communicate effectively often benefit from creating a customized parenting plan that suits their family’s unique needs. A family lawyer can help ensure the agreement is legally sound and protects everyone involved.

Custody arrangements are not always permanent. If there is a material change in circumstances, a custody order may be reviewed or modified. Examples include relocation, changes in a child’s needs, or concerns about a parent’s ability to provide care.
Courts will reassess the situation and determine whether a change is necessary to protect the child’s best interests.
Child custody disputes are emotionally charged and legally complex. Having proper legal guidance ensures that your rights are protected and that the focus remains on your child’s well-being.
