1. New Terminology, What Replaced Custody and Access in Ontario

On March 1, 2021, amendments to the federal Divorce Act came into force across Canada, replacing the terms “custody” and “access” with new language that reflects a less adversarial approach to parenting after separation.

Old TermNew TermWhat It Means
CustodyDecision-making responsibilityWho makes major decisions for the child: education, healthcare, religion, extracurricular activities.
AccessParenting timeThe time each parent physically spends with the child. Replaces the adversarial implication that one parent has “access” as a lesser right.
Custody orderParenting orderThe court order setting out each parent’s decision-making responsibilities and parenting time.
Why the change? The old “custody vs. access” framing created a win-lose dynamic that was harmful to children and families. Parents with “access” often felt like visitors in their children’s lives. The new language emphasizes that both parents retain responsibilities for their children’s wellbeing, regardless of living arrangements. For files under the Ontario Children’s Law Reform Act (non-married parents), similar but slightly different terminology applies.

2. Decision-Making Responsibility

Decision-making responsibility refers to the authority to make significant decisions about a child’s life, not day-to-day parenting decisions (each parent makes those during their own parenting time), but major decisions about:

Sole vs. Joint Decision-Making Responsibility

Joint decision-making responsibility means both parents share the authority to make major decisions, they must consult each other and attempt to reach agreement. This does not require 50/50 parenting time. Joint decision-making is the most common arrangement in Ontario where parents are capable of communication.

Sole decision-making responsibility means one parent has the final authority to make major decisions. Courts award sole decision-making responsibility where joint decision-making is not workable, typically in high-conflict cases, situations involving family violence, or where one parent is persistently uncooperative. It is not automatically granted to the parent who has more parenting time.

Joint does not mean equal. Joint decision-making responsibility has nothing to do with how parenting time is divided. A parent can have joint decision-making responsibility but only 20% of parenting time, or vice versa. The two questions are separate.

3. Parenting Time and Schedules

Parenting time is the time each parent physically spends with the child. There is no legal presumption of equal parenting time in Ontario. The arrangement that best serves the child’s interests, based on all the circumstances, is what courts will order.

Common Parenting Schedules

ScheduleDescriptionBest Suited For
Week on/week off (50/50)Child alternates weekly between each parent’s home.Parents living close together, school-age children, cooperative co-parenting relationship.
Primary/secondary (70/30)Child primarily lives with one parent; other parent has every other weekend and one weeknight per week.Situations where one parent has been the primary caregiver, or where distance or work schedules make 50/50 impractical.
2-2-3 rotationChild alternates 2 days with one parent, 2 with the other, 3 with the first, then reverses.Younger children who benefit from more frequent contact with each parent; requires high parental cooperation.
Supervised parenting timeParenting time occurs in the presence of a supervisor (professional or agreed-upon third party).Situations involving safety concerns, family violence history, or where a parent-child relationship needs to be re-established carefully.

4. The Best Interests of the Child, How Courts Decide

The Divorce Act requires courts to consider only the best interests of the child when making any parenting order. There is no presumption in favour of either parent, and no automatic preference for mothers over fathers or vice versa.

The 2021 Divorce Act amendments codified a non-exhaustive list of factors courts must consider:

The child’s needs and circumstances

Age, developmental stage, special needs, cultural background, and what arrangements have provided stability to date.

The child’s relationships

The nature and strength of the child’s relationships with each parent, siblings, grandparents, and other significant people.

Each parent’s willingness to support the child’s relationship with the other parent

This factor often has decisive weight. A parent who actively undermines the child’s relationship with the other parent is viewed very negatively by courts.

History of caregiving

Who has historically been the primary caregiver? Courts consider the division of parenting responsibilities during the relationship.

Each parent’s parenting ability

Each parent’s capacity to meet the child’s physical, emotional, cultural, and psychological needs.

Any family violence

The 2021 amendments made family violence an explicit factor. Courts must consider the impact of family violence on the child’s safety and wellbeing. A history of violence can significantly limit a parent’s parenting time or decision-making responsibility.

The child’s own views and preferences

Depending on age and maturity, the child’s own preferences are given weight. Courts do not conduct direct interviews with children, a report from the Office of the Children’s Lawyer is the usual mechanism.

Stability and continuity

Maintaining stability in the child’s schooling, community, and routines. Courts are generally reluctant to disrupt an arrangement that is working for the child.

There is no age at which a child can “choose” which parent to live with. While a child’s views are given more weight as they get older, a teenager cannot simply decide to live exclusively with one parent without a court order. If parenting time arrangements need to change as a child ages, the parties need either a new agreement or a court variation order.

5. Relocation With a Child

One of the most significant changes in the 2021 Divorce Act amendments was a new relocation framework. If you want to move and take your child with you, new procedural rules apply.

The Relocation Process

A parent who wants to relocate with a child must give the other parent (and any other person with parenting time) at least 60 days written notice before the planned move. The notice must include the new address and contact information, the expected date of the move, a proposed revised parenting schedule, and how communication will be maintained.

If the other parent objects, the parent wishing to relocate must apply for a court order. The court then applies the best interests of the child test, with additional considerations:

Relocation cases are complex and high-stakes. A parent who relocates without proper notice or court approval may be ordered to return the child. A parent who objects to a relocation may inadvertently harm their case if their objection appears motivated by desire to control rather than concern for the child. Legal advice before any relocation step is essential.

6. Parenting Plans

A parenting plan is a written agreement between parents that sets out how parenting responsibilities and time will be divided. Courts strongly encourage parenting plans as an alternative to contested custody proceedings. A well-drafted parenting plan covers:

A parenting plan agreed to by both parties can be filed with the court and incorporated into a court order, giving it the force of an order that can be enforced if breached.

7. The Office of the Children’s Lawyer

The Office of the Children’s Lawyer (OCL) is an Ontario government office that can be appointed by a court to independently represent the interests of a child in family law proceedings. The OCL becomes involved in high-conflict cases where the court needs independent information about the child’s circumstances and wishes.

The OCL may provide:

OCL involvement cannot be requested by parents directly. The OCL can only be involved when appointed by the court. Judges typically consider OCL involvement when parents cannot agree, when allegations of abuse or family violence are made, or when the child’s own views are particularly relevant.

Parenting time and child support are legally separate questions, but they interact. In Ontario:

Child support is a right of the child. It cannot be waived by either parent. A separation agreement that purports to eliminate child support is not enforceable. Even where one parent “agrees” to give up support, courts can still order it. Section 7 expenses are also not optional.

9. Frequently Asked Questions

What replaced custody and access in Ontario?

The 2021 Divorce Act amendments replaced “custody” with “decision-making responsibility” (who makes major decisions for the child) and “access” with “parenting time” (the time each parent spends with the child). The underlying legal concepts are similar, but the new language reduces the adversarial framing of custody disputes.

How does a court decide who gets decision-making responsibility in Ontario?

Courts apply the best interests of the child standard, considering the child’s needs and circumstances, relationships with each parent, history of caregiving, each parent’s ability to support the child’s relationship with the other parent, any history of family violence, and the child’s own views. There is no presumption in favour of either parent.

Can a parent relocate with a child after separation in Ontario?

A parent who wants to relocate must give the other parent at least 60 days written notice. If the other parent objects, a court order is required. The test is the best interests of the child, including the reason for the move, its impact on the child, and whether meaningful parenting time with the other parent remains possible.

Does 50/50 parenting time mean no child support?

Not necessarily. Shared parenting arrangements use the set-off method, each parent’s obligation is calculated and the higher earner pays the difference. Even with equal parenting time, the parent who earns more usually pays something to equalize the child’s standard of living across both households.

What is the Office of the Children’s Lawyer?

The OCL is a provincial government office that can be appointed by a court to independently represent a child’s interests in family proceedings. It provides either a Voice of the Child report (an interview of the child by a social worker) or legal representation for the child. Parents cannot directly request OCL involvement, only judges can appoint them.

Can I change a custody or parenting arrangement after it is ordered?

Yes. Either parent can apply to vary a parenting order if there has been a material change in circumstances since the order was made, a change that, if known at the time, might have resulted in a different order. Examples include one parent relocating, a child’s needs changing significantly, or a parent’s circumstances substantially changing. The best interests of the child test is applied to the variation application.
