Key takeaways
  • Decision-making responsibility covers significant decisions about a child's health, education, culture, language, religion and spirituality, and significant extra-curricular activities.
  • A court can give decision-making responsibility, or any part of it, to one parent, to both, or split it between them, with the child's safety, security and well-being as the primary consideration.
  • Parents can agree on decision-making in a separation agreement or parenting plan, but a court may disregard those terms if that is in the child's best interests.

When parents separate, one of the first questions is who gets to make the big decisions about the children. This used to be called custody. Ontario law now uses the term decision-making responsibility, though older orders and agreements still use the old word.

This article explains what decision-making responsibility covers, how it differs from everyday decisions, what sole, joint and divided orders mean, and how courts choose between them. It is general information, and a lawyer can tell you how it applies to your family.

What decision-making responsibility covers

Decision-making responsibility is about significant decisions concerning a child's well-being. These include health, education, culture, language, religion and spirituality, and significant extra-curricular activities.

Day-to-day decisions are different. The person who has parenting time has exclusive authority over day-to-day decisions during that time, unless the court orders otherwise.

Type of decisionWho generally makes it
Significant decisions such as health, education and religionThe person or people with decision-making responsibility
Day-to-day decisionsThe person with parenting time, during that time

The terms decision-making responsibility and parenting time replaced custody and access. If you have an older order or agreement, it may still use the old words, and it is worth asking a lawyer how it lines up with the current terms.

Which law applies to you

It depends on your marital status. The federal Divorce Act governs parenting between married spouses. Ontario's Children's Law Reform Act (CLRA) applies to unmarried or common-law parents and to married parents who are not divorcing. The two laws have parallel but separately numbered sections.

Under the CLRA, a child's parents start with an equal right to decision-making responsibility, whether or not they were ever married.

What changes after separation

If the parents live apart and the child lives with one parent with the other's consent, implied consent or acquiescence, the other parent's right to exercise decision-making responsibility is suspended until a separation agreement or court order says otherwise.

That suspension does not touch parenting time. Parenting time includes the right to visit with the child and to make inquiries and receive information about the child's well-being. Unless a court orders otherwise, a person with decision-making responsibility or parenting time may also ask for and receive information about the child's well-being.

Sole, joint and divided orders, and how courts choose

A court may allocate decision-making responsibility, or any part of it, to either spouse, to both, or to a non-spouse. This is how sole, joint and divided orders are made.

In choosing, the court's primary consideration is the child's physical, emotional and psychological safety, security and well-being. The best-interests factors include the child's needs given age and stage of development, the child's relationships, the history of care, the child's views and preferences, each parent's ability to communicate and cooperate, and family violence. They also include each parent's willingness to support the child's relationship with the other parent.

The list is not exhaustive, so a court may consider other factors while always giving priority to the child's safety. The court does not consider a person's past conduct unless it is relevant to their parenting time, decision-making responsibility or contact. Whether a joint or sole order fits depends on the facts of your family, and a lawyer can help you assess that.

Agreements and parenting plans

Separated cohabitants may agree in a separation agreement on decision-making responsibility and parenting time for their children. A domestic contract is unenforceable unless it is in writing, signed by the parties and witnessed.

An agreement does not bind the court on these issues. A court may disregard a provision on decision-making responsibility or parenting time if that is in the child's best interests. When the court makes a parenting order, it must include a written parenting plan the parties have agreed on, though it may change the plan if that is in the child's best interests.

A good plan spells out how decisions will be made and what happens with the schedule, holidays and travel. Each parent should show the draft plan to their own legal adviser before signing.

What to do next

Frequently asked questions

Is decision-making responsibility the same as custody?

It replaced the old idea of custody for significant decisions about a child. Parenting time replaced access. Older orders and agreements may still use the old words.

If my child lives with the other parent with my consent, do I lose all my rights?

Not all of them. Your right to exercise decision-making responsibility can be suspended in that situation until an agreement or order says otherwise, but your parenting time is not suspended. You also keep the right to make inquiries and receive information about the child's well-being.

Does the court prefer joint decision-making?

The law gives the court the option of sole, joint or divided orders. The choice turns on the child's best interests, with safety first. A lawyer can tell you how this may apply to your facts.

Can the court ignore our signed agreement?

Yes, on these issues. A court may disregard a provision on decision-making responsibility or parenting time if that is in the child's best interests.
