Introduction
When parents separate or divorce, one of the most important issues they face is determining who will care for their children. In Ontario family law, the terms child custody and child access are often used, but they have distinct meanings. Understanding the differences between custody and access is critical for making informed decisions and protecting your parental rights.
Working with an experienced family lawyer can help you navigate these sensitive matters. At Khan LLP, we provide guidance on all aspects of family law, including custody, access, and parental responsibilities.
What Is Child Custody?
In Ontario, child custody refers to the legal right and responsibility to make major decisions about a child’s life. These decisions include:
- Education (e.g., choice of school)
- Health care and medical treatment
- Religion and cultural upbringing
- General welfare and daily care
Custody does not necessarily mean where the child lives. Instead, it relates to decision-making authority. There are several types of custody arrangements:
- Sole Custody – One parent makes all major decisions.
- Joint Custody – Both parents share decision-making power.
- Shared Custody – Parents share custody when each has the child at least 40% of the time.
Each arrangement depends on the best interests of the child, which is the guiding principle in Ontario courts.
What Is Child Access?
While custody deals with decision-making, child access refers to the right of a parent to spend time with their child. Access arrangements define when and how a parent who does not have custody can interact with the child.
Forms of access may include:
- Reasonable Access – Flexible schedules based on the parents’ agreement.
- Fixed Access – Specific times and dates for visits, often set by a court order.
- Supervised Access – Required when safety or well-being is a concern.

Custody vs Access: The Key Differences
Although the two terms are often used together, they serve different purposes:
- Custody – Who makes important decisions for the child.
- Access – How much time the child spends with each parent.
In some cases, a parent may have custody, but the other parent has generous access. In others, both parents may share joint custody, with access divided equally or unevenly.
The courts always consider the child’s best interests when determining custody and access, which includes factors like emotional stability, parental involvement, and the child’s preferences (depending on age and maturity).
Parental Rights and Responsibilities
Parents in Ontario have both rights and obligations when it comes to custody and access. Some key principles include:
- Both parents are generally entitled to be involved in their child’s life.
- Parents have the right to information about their child’s health, education, and well-being.
- Denying access without a valid reason can lead to legal consequences.
- Custody decisions must always prioritize the child’s safety, health, and emotional needs.
Even when one parent is awarded sole custody, the other parent often retains access rights unless it is not in the child’s best interest.

How Courts Decide Custody and Access
Ontario courts use the best interests of the child test when making custody and access decisions. Factors include:
- The child’s emotional ties to each parent
- The stability of the proposed living arrangements
- Each parent’s ability to provide care
- The child’s cultural, linguistic, and religious background
- The child’s own wishes, depending on age
Courts aim to create arrangements that maintain strong, positive relationships between children and both parents whenever possible.
Modifying Custody or Access
Life circumstances can change after a custody or access order is made. Parents may need to request modifications due to:
- Relocation for work or family reasons
- Changes in a parent’s financial or living situation
- Concerns about the child’s well-being
- The child’s changing needs as they grow older
A family lawyer can assist in bringing a motion to court to vary the existing order.

Disputes and Legal Help
Disagreements about custody and access are common, especially during divorce or separation. Mediation or negotiation often helps resolve disputes without going to court. However, if conflict continues, a judge may need to make a binding decision.
Having professional legal representation is essential. At Khan LLP, our family law team ensures that custody and access arrangements prioritize your child’s needs while protecting your parental rights.
Conclusion
The difference between child custody and child access is simple but important: custody is about making major decisions, while access is about spending time with your child. Both arrangements aim to serve the best interests of the child.
