What Do Judges Look for in Child Custody Cases in Ontario?

When parents separate, one of the most important—and often most emotional—questions is who will care for the child and make decisions about their upbringing. In Ontario, this is no longer framed as “custody” and “access” but as decision-making responsibility and parenting time, under both the Divorce Act and the Children’s Law Reform Act. Regardless of terminology, the guiding principle remains clear: the best interests of the child come first.

So, what exactly do judges consider when deciding parenting arrangements? Let’s break it down.

The Best Interests of the Child

The cornerstone of every parenting decision is the best interests of the child. This legal standard requires the court to focus on what will most benefit the child’s well-being, not the preferences of either parent. Judges do not automatically favor mothers over fathers; instead, they examine which arrangement promotes stability, safety, and healthy development.

Key considerations include:

  • Physical needs: Who can provide a secure home, proper nutrition, and basic care?
  • Emotional needs: Which parent can offer love, attention, and support for the child’s mental well-being?
  • Psychological and social needs: How can the child maintain healthy relationships and a sense of belonging?

If a child has special needs or a disability, judges also weigh which parent is better able to provide the necessary care and resources.

Stability and Continuity

Stability is critical for a child’s growth and adjustment after separation. Judges consider factors such as:

  • Where the child has been living and attending school
  • The importance of keeping siblings together
  • Maintaining ties to community, friends, and extended family

Frequent disruptions or major lifestyle changes can be harmful, so courts generally favor arrangements that preserve continuity—especially for younger children.

Parental Capacity and Cooperation

Judges assess each parent’s ability to meet the child’s needs consistently. This goes beyond financial support. It includes the capacity to:

  • Provide education and guidance
  • Support the child’s cultural, linguistic, religious, and spiritual upbringing
  • Encourage the child’s relationship with the other parent

One crucial element is cooperation. Courts look closely at whether each parent can communicate effectively and put the child’s interests above personal conflict. A parent who tries to alienate the child from the other parent, or refuses to share information, may harm their own case.

The Child’s Views and Preferences

Children’s voices matter, but they do not make the final decision. Judges take their wishes into account if they are mature enough to express them freely and understand the implications. For younger children, this carries less weight. For older teenagers, their preferences may significantly influence the outcome, provided those wishes align with their best interests.

Often, the child’s perspective is obtained through a Views of the Child Report or an investigation by the Office of the Children’s Lawyer (OCL). These processes ensure that the child’s input is heard in a neutral and safe manner.

Safety and History of Violence

Judges must also ensure the child is protected from any risk of harm. A history of family violence, abuse, or coercive control can heavily impact parenting decisions. The court will examine whether the child has been exposed to conflict and whether either parent poses a risk to the child’s safety or emotional well-being.

This includes considering any restraining orders, criminal charges, or previous involvement with child protection services. The goal is always to provide an environment that is free from fear and instability.

In summary, Ontario judges look at the big picture: what arrangement will allow the child to thrive physically, emotionally, and psychologically. This means evaluating parenting capacity, the ability to cooperate, the child’s needs and preferences, and any safety concerns. There is no automatic formula or bias toward one parent; every decision is tailored to the child’s unique circumstances.

For parents, understanding these factors is crucial. Approaching the process with a focus on the child—not the conflict—can make all the difference, both in the courtroom and in the child’s life.
