Joint vs. Sole Custody: Understanding Your Decision-Making Rights

The laws have changed. Here is how Ontario courts now define ‘Custody’ and ‘Parenting Time’ under the reformed CLRA.

Legal Strategy reviewed by Deepa Tailor, Senior Family Lawyer. Updated January 2026 to reflect current Ontario custody law and the reformed Children's Law Reform Act (CLRA) terminology.

Too Busy to Read? The 30-Second Answer

The Terminology Shift: Ontario courts have largely replaced the word "Custody" with "Decision-Making Responsibility."
Joint Decision-Making (Formerly Joint Custody): Both parents must agree on major choices (Religion, Education, Health). It requires high cooperation.
Sole Decision-Making (Formerly Sole Custody): One parent makes the final call. The other parent usually still has information rights and visitation.
The Key Distinction: "Custody" is about Decisions, not Schedule. You can have Joint Custody but only see the child every other weekend.

The Two Pillars of Parenting Law

Decision-Making Responsibility

(The Mind)

Formerly 'Custody'. This refers to who makes the major life choices:

  • 1.Health Care
  • 2.Education
  • 3.Religion
  • 4.Significant extracurriculars

Parenting Time

(The Schedule)

Formerly 'Access'. This refers strictly to where the child sleeps and physically resides.

Having 'Decision-Making' power does not automatically mean you get 50% of the time.

Which Arrangement is Right for You?

Joint Decision-Making

Pros

  • •Child benefits from both perspectives
  • •Parents feel equally involved

Cons

  • •High conflict risk
  • •If parents cannot communicate effectively, this arrangement fails quickly

Best For:

Parents who can separate their personal feelings from their parenting duties.

Sole Decision-Making

Pros

  • •High stability
  • •Decisions are made quickly without arguments

Cons

  • •The other parent may feel alienated or excluded

Best For:

High-conflict relationships, situations involving domestic violence, or when one parent is largely absent.

Busting Common Custody Myths

The 50/50 Myth

Myth: "If we have Joint Custody, I automatically get the kids 50% of the time."

The Legal Reality

Reality: No. You can have Joint Decision-Making power while the children live primarily with the other parent. The schedule is determined by the 'Best Interests of the Child,' not the decision‑making label.

How Judges Decide: The 'Best Interests' Test

Under the Children's Law Reform Act (CLRA), the court looks at specific factors:

The child's views and preferences (depending on age).

The history of care (Who has been the primary caregiver?).

The ability of each parent to act as a parent (and cooperate).

Any history of family violence (This is heavily weighted).

The stability of the home environment.
